Statins are widely used for cardiovascular protection, but their effect on AKI remains uncertain. This study aims to investigate the association between statin therapy and the prognosis of critically ill patients with myocardial infarction-related acute kidney injury (AMI-AKI), providing evidence-based support for clinical decision-making. Methods: AMI-AKI patients were extracted from the MIMIC-IV database and divided into a statin group and a non-statin group based on statin use during their intensive care unit (ICU) stay. The primary outcome was 28-day mortality, and secondary outcomes included 90-day mortality, in-hospital mortality, and ICU mortality. Propensity score matching (PSM) and inverse probability of treatment weighting (IPTW) were used to balance baseline differences between groups. Cox proportional hazards models and logistic regression models assessed the association of statin use, statin type, and statin dosage with clinical outcomes. Survival analysis was performed using Kaplan-Meier curves and Log-rank tests, and subgroup analyses were conducted to explore effect heterogeneity. Results: A total of 3,844 AMI-AKI patients were included, of whom 72.6% received statin therapy during their ICU stay. Multivariable model results showed that statin use was significantly associated with reduced risks of 28-day mortality (HR = 0.621, 95% CI : 0.529-0.729), 90-day mortality (HR = 0.710, 95% CI : 0.617-0.816), in-hospital mortality (OR = 0.612, 95% CI : 0.489-0.767), and ICU mortality (OR = 0.535, 95% CI : 0.414-0.691). These associations remained significant after PSM and IPTW adjustments. Patients receiving simvastatin and standard-dose therapy showed the greatest reduction in mortality. Subgroup analysis revealed that the protective effect of statins was particularly pronounced in patients with AKI stage 3, age ≤65 years, those not using antiplatelet drugs, those without concomitant chronic heart failure (CHF), those undergoing coronary artery bypass grafting (CABG), or those receiving beta-blockers. Conclusion: Statin therapy is significantly associated with lower mortality risk in AMI-AKI patients, particularly with simvastatin and standard-dose strategies. This study supports integrating statins into the comprehensive treatment for critically ill AMI-AKI patients to improve clinical outcomes.

Introduction Acute myocardial infarction (AMI) is a critical condition resulting from thrombotic occlusion due to coronary plaque rupture or erosion, leading to myocardial ischemic hypoxia injury and necrosis. It can be classified into ST-segment elevation myocardial infarction (STEMI), caused by complete coronary artery occlusion, and non-ST-segment elevation myocardial infarction (NSTEMI), caused by partial or intermittent occlusion. Epidemiological data indicate that the prevalence of AMI is as high as 23.3%, with a mortality rate ranging from 7% to 10%, making it a significant cause of death among patients in intensive care unit (ICU) [ 1 ] . Acute kidney injury (AKI), a common complication in hospitalized patients with AMI, occurs in 12.1% to 55.6% of cases [ 2 ] . Its pathogenesis involves multiple pathophysiological processes, including ischemia-reperfusion injury, oxidative stress, inflammation, and nephrotoxicity [ 3 – 6 ] . AKI is an independent risk factor affecting both short-term and long-term prognosis in AMI patients, and mortality in patients with concomitant AKI is more than 10 times higher than in those without [ 7 ] . Therefore, strengthening clinical intervention for AKI following AMI is particularly urgent. Statins, or 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors, are widely used for the primary and secondary prevention of cardiovascular events due to their established lipid-lowering efficacy [ 8 ] . Their pleiotropic effects, including anti-inflammatory, immunomodulatory, and antioxidant activities, have expanded their potential applications in other diseases [ 9 – 11 ] . Studies have shown that statins significantly reduce cardiac and all-cause mortality in patients with AMI [ 12 ] , and multiple studies have also suggested their ability to lower the risk of developing AKI [ 13 – 15 ] . Furthermore, a retrospective study by Tang et al. involving 5,376 patients with chronic kidney disease (CKD) reported that statin users had a 55% lower risk of in-hospital mortality compared with non-users [ 16 ] . A retrospective study by Zheng et al. involving 2,034 patients with AKI also confirmed that statin use was significantly associated with reduced in-hospital mortality, although this association was only statistically significant in the atorvastatin subgroup [ 17 ] . However, conflicting findings exist: a large cohort study of 43,438 patients reported that statin users had a 30% increased risk of developing AKI compared to non-users [ 18 ] . Similarly,a study by Wang et al. observed no significant improvement in prognosis with statin use in patients with severe AKI associated with sepsis [ 19 ] . Currently, research on the impact of statins on short-term and long-term outcomes in AMI patients complicated by AKI remains limited. Given the contradictory nature of the existing evidence and the lack of specific clinical guidelines for statin therapy in this particular patient population, this study utilized real-world data to systematically evaluate the association between statin therapy and clinical outcomes in AMI patients with concomitant AKI, aiming to provide refined, evidence-based support for clinical pharmacotherapy in this group. 2. Methods 2.1Data Source Data for this study were obtained from the publicly available Medical Information Mart for Intensive Care IV (MIMIC-Ⅳ-2.2) database, which contains clinical information on critically ill patients admitted to the Beth Israel Deaconess Medical Center between 2008 and 2019. All patient information in the database has been de-identified to protect privacy; therefore, this study was granted an exemption for ethical approval and the requirement for informed consent was waived. One of the authors (Jiahui Li) completed the Collaborative Institutional Training Initiative (CITI) program and passed the relevant examinations (Certification No.: 10125720) to obtain access to the database. 2.2 Inclusion and Exclusion Criteria Patients diagnosed with AMI were identified using the International Classification of Diseases (ICD) code 9/10 (see Supplementary Table 1). Among these patients, those who developed AKI during their ICU stay were included. AKI was defined according to the Kidney Disease Improving Global Outcomes (KDIGO) criteria [ 20 ] : an increase in serum creatinine (SCr) by ≥ 0.3 mg/dL (26.5 µmol/L) within 48 hours, or an increase in SCr to ≥ 1.5 times baseline within 7 days, or urine output ≤ 0.5 mL/(kg·h) for 6 hours. Exclusion criteria were as follows: (1) patients with multiple ICU admissions, only the first ICU admission was included; (2) patients aged < 18 years; and(3) ICU stay duration < 24 h (discharged or death). 2.3 Data Extraction Clinical data during hospitalization were extracted from the MIMIC-IV-2.2 database using the database management tool Navicat Premium (version 16.3.7) via Structured Query Language (SQL). The extracted variables included: (1) Demographic information: age, sex, race, weight, height, insurance type, smoking history, and alcohol consumption history; (2) Vital signs measured within the first 24 hours of ICU admission: heart rate, respiratory rate, systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), peripheral oxygen saturation (SpO₂), and urine output; (3) Laboratory parameters measured within the first 24 hours of ICU admission: white blood cell (WBC) count, platelet count, blood glucose, hemoglobin, blood urea nitrogen (BUN), creatinine, red cell distribution width (RDW), anion gap, lactate, international normalized ratio (INR), activated partial thromboplastin time (APTT), potassium, sodium, calcium, and troponin T (TNT); (4) Comorbidities: hypertension, congestive heart failure (CHF), peripheral vascular disease (PVD), cerebrovascular disease (CVD), chronic pulmonary disease, chronic kidney disease (CKD), malignancy, liver disease, diabetes, obesity, and hyperlipidemia; (5) Disease severity scores: Sequential Organ Failure Assessment (SOFA), Simplified Acute Physiology Score II (SAPS II), Oxford Acute Severity of Illness Score (OASIS), and Charlson Comorbidity Index (CCI); (6) Therapeutic interventions within 48 hours of ICU admission: mechanical ventilation, vasopressors, coronary artery bypass grafting (CABG), percutaneous coronary intervention (PCI), and continuous renal replacement therapy (CRRT); (7) Medications administered within 48 hours of ICU admission: beta-blockers, antiplatelet agents, angiotensin-converting enzyme inhibitors (ACEI), and angiotensin II receptor blockers (ARB); and(8) Outcome variables: 28-day mortality, 90-day mortality, in-hospital mortality, and ICU mortality. For missing data (covariate missingness is illustrated in Supplementary Fig. 1), variables with a missing rate exceeding 20% were excluded. Variables with a missing rate below 20% were imputed using Multiple Imputation by Chained Equations (MICE), generating five imputed datasets. After imputation, estimates from the five datasets were pooled according to Rubin's rules to account for the uncertainty associated with missing data. This process was performed using the "mice" package in R software. 2.4 Statin Use Patterns Patients were divided into a non-statin group and a statin group based on their receipt of statin therapy during the ICU stay. Furthermore, the association between different types of statins and mortality was evaluated by examining four commonly used statins: simvastatin, rosuvastatin, pravastatin, and atorvastatin. To further explore the impact of statin dosage on patient mortality, patients were categorized into a standard-dose group and a high-dose group according to the administered statin dose. High-dose statin therapy was defined as a daily dose exceeding the following thresholds: simvastatin 40 mg, rosuvastatin 20 mg, pravastatin 40 mg, and atorvastatin 80 mg [ 21 ] .Patients receiving multiple types of statins or varying doses were excluded to ensure consistency in exposure assessment. 2.5 Clinical Outcomes The primary outcome was 28-day mortality. Secondary outcomes included 90-day mortality, in-hospital mortality, and ICU mortality. 2.6 Statistical Analysis The Shapiro-Wilk test was used to assess the normality of continuous variables. Normally distributed data are presented as mean ± standard deviation (SD) and were compared using the independent samples t-test. Non-normally distributed data are expressed as median (interquartile range, IQR) and were analyzed with the Mann-Whitney U test. Categorical variables, presented as frequencies (percentages), were compared using the chi-square or Fisher's exact test, as appropriate. Based on a directed acyclic graph (DAG), confounding variables requiring adjustment were identified. Only baseline variables influencing both exposure and outcome were included, while post-exposure variables or mediating variables were avoided. To mitigate imbalances in baseline characteristics between the two groups, propensity score matching (PSM) and inverse probability of treatment weighting (IPTW) were employed. Specifically, propensity scores (PS) were calculated using a multivariate logistic regression model incorporating all baseline covariates. A 1:1 nearest neighbor matching algorithm with a caliper width of 0.05 and without replacement was applied to generate a matched cohort with comparable baseline characteristics. Simultaneously, stabilized inverse probability weights based on the PS were used to construct two pseudo-populations, with weights truncated at the 1st and 99th percentiles to control extreme values. The balance of covariates after PSM and IPTW was assessed using standardized mean differences (SMD), with |SMD| < 0.1 indicating adequate balance, and visualized using density plots. Cox proportional hazards regression and logistic regression models were constructed in the original, matched, and weighted cohorts to evaluate the association between statin use and patient mortality. The multivariate model incorporates confounding variables including: demographic information (insurance type, race, sex, age, weight, smoking history, alcohol consumption history), vital signs (heart rate, respiratory rate, MAP, SBP, blood oxygen saturation, urine output), laboratory parameters (WBC, platelet count, hemoglobin, BUN, creatinine, RDW, anion gap, INR, APTT, potassium, sodium, calcium), comorbidities (hypertension, CHF, CVD, chronic pulmonary disease, CKD, malignancy, liver disease, diabetes, obesity, hyperlipidemia),severity scores of the disease(CCI, SOFA, OASIS, SAPS II), therapeutic interventions (mechanical ventilation, vasopressor use, CRRT), and medications (beta-blockers, antiplatelet agents, ACEI, ARB). Multicollinearity among variables was assessed using the variance inflation factor (VIF), and variables with VIF > 10 were excluded. All variables included in the multivariate Cox regression models had VIF < 10 (see Supplementary Fig. 5). Kaplan-Meier survival curves were estimated for 28-day and 90-day survival in the non-statin and statin groups within the original, matched, and weighted cohorts, with differences between groups compared using the log-rank test. In the original cohort, multivariate Cox and logistic regression models were constructed to assess the association between statin type and dosage with mortality, adjusting for the same variables as described above. Finally, subgroup analyses were performed to evaluate the consistency of the association between statin use and 28-day and 90-day mortality across different patient populations. Stratification was based on age (> 65 years or ≤ 65 years), sex (male or female), weight (> 80 kg or ≤ 80 kg), AKI stage (1, 2, or 3), comorbidities (CVD, CKD, CHF, diabetes, hyperlipidemia), therapeutic interventions (mechanical ventilation, vasopressors, CRRT, CABG), and medications (beta-blockers and antiplatelet agents), with interaction terms introduced for testing. All statistical analyses were performed using R software (version 4.5.1). All tests were two-sided, and P < 0.05 was considered statistically significant. 3. Results 3.1 Baseline Characteristics The patient selection process is illustrated in Fig. 1 . A total of 3,844 patients with AMI-AKI meeting the inclusion criteria were enrolled in this study. Among them, 2,792 patients (72.6%) received statin therapy after ICU admission, while 1,052 patients (27.4%) did not receive statins during this period. After PSM adjustment, 899 patients in the statin group and 899 patients in the non-statin group were included. Baseline characteristics of the original cohort are presented in Table 1 . Significant differences in multiple baseline characteristics were observed between the two groups (SMD > 0.1). Specifically, compared to the non-statin group, patients in the statin group had a higher proportion of males and greater body weight. Regarding vital signs, patients receiving statins exhibited relatively higher oxygen saturation and urine output, but lower heart rate and respiratory rate. Laboratory parameters showed that the statin group had relatively higher white blood cell count, hemoglobin, and calcium levels, but lower BUN, creatinine, anion gap and INR. Disease severity scores (including SOFA, OASIS, SAPS II, and CCI) were lower in the statin group compared to the non-statin group. Regarding comorbidities, the statin group had higher proportions of hypertension, chronic pulmonary disease, diabetes, obesity, and hyperlipidemia, but lower proportions of CHF, malignancy, and liver disease. In terms of therapeutic interventions, the number of patients receiving mechanical ventilation on the first day of ICU admission was higher in the statin group, while vasopressor use and CRRT were more common in the non-statin group. Patients in the statin group were more likely to undergo PCI and CABG. Furthermore, the proportion of patients receiving beta-blockers, antiplatelet agents, and ACEI was higher in the statin group.

Analysis Results DAG was constructed to identify confounders and mediators in the association between statin use and mortality (see Fig. 2 ). Confounders identified included: age, alcohol consumption history, smoking history, comorbidities (hypertension, CHF, PVD, CVD, chronic pulmonary disease, CKD, malignancy, diabetes, liver disease, obesity, and hyperlipidemia), and disease severity scores (SOFA, SAPS II, OASIS, and CCI). Relevant variables included: vital signs (heart rate, respiratory rate, SBP, DBP, MAP, oxygen saturation, urine output), laboratory parameters (WBC, platelet count, blood glucose, hemoglobin, BUN, creatinine, RDW, anion gap, INR, APTT, potassium, sodium, calcium), therapeutic interventions (mechanical ventilation, vasopressors, CRRT, PCI, CABG), and medications (beta-blockers, antiplatelet agents, ACEI, ARB). No mediators were identified. Confounders were required to be included in the regression models. Furthermore, as relevant variables may also act as confounders, they were considered for inclusion in the models. 3.3 Association Between Statin Use and Patient Mortality In unadjusted models, statin use was significantly associated with a reduced risk of 28-day mortality (HR = 0.446, 95% CI : 0.387–0.514, P < 0.001), 90-day mortality (HR = 0.491, 95% CI : 0.433–0.556, P < 0.001), in-hospital mortality (OR = 0.407, 95% CI : 0.342–0.484, P < 0.001), and ICU mortality (OR = 0.388, 95% CI : 0.319–0.471, P < 0.001). In multivariable-adjusted models, compared to the non-statin group, patients in the statin group exhibited a 37.9% reduction in 28-day mortality, a 29.0% reduction in 90-day mortality, a 38.8% reduction in in-hospital mortality, and a 46.5% reduction in ICU mortality. The significant protective effect of statins was consistently observed in both the matched and weighted cohorts (see Fig. 3 ). 3.4 Kaplan-Meier Survival Curves In the original cohort, patients with AMI-AKI in the statin group demonstrated significantly higher 28-day and 90-day survival rates compared to those in the non-statin group (P < 0.001; Fig. 4 A, B). The survival curves for the matched cohort (Fig. 4 C, D) and the weighted cohort (Fig. 4 E, F) were consistent with those of the original cohort (all P < 0.05). 3.5 Association of Statin Type and Dosage with Patient Mortality After applying the exclusion criteria, 2,593 patients were identified as having received a single type and dosage of statin therapy. The distribution of statin use was as follows: simvastatin (n = 247), rosuvastatin (n = 163), pravastatin (n = 91), and atorvastatin (n = 2,092). Table 3 shows the association between different types of statins and mortality. Compared with the non-statin group, the use of simvastatin and atorvastatin was significantly associated with lower mortality among patients with AMI-AKI. Specifically, patients receiving simvastatin exhibited a 54.5% reduction in 28-day mortality (HR = 0.455, 95% CI : 0.315–0.658, P < 0.001), a 42.7% reduction in 90-day mortality (HR = 0.573, 95% CI : 0.425–0.772, P < 0.001), a 60.5% reduction in in-hospital mortality (OR = 0.395, 95% CI : 0.242–0.645, P < 0.001), and a 71.1% reduction in ICU mortality (OR = 0.289, 95% CI : 0.157–0.534, P < 0.001). Atorvastatin also demonstrated a significant protective effect, with reductions of 36.1%, 27.6%, 39.1%, and 35.4% in 28-day, 90-day, ICU, and in-hospital mortality, respectively. However, no significant association with reduced mortality was observed for rosuvastatin or pravastatin (all P > 0.05).

Regarding dosage stratification, 819 patients received standard-dose statin therapy, and 1,774 patients received high-dose statin therapy. As shown in Table 4 , compared to patients in the non-statin group, those receiving standard-dose statin therapy had significantly reduced 28-day (HR = 0.497, 95% CI : 0.397–0.622, P < 0.001), 90-day (HR = 0.612, 95% CI : 0.508–0.736, P < 0.001), in-hospital (OR = 0.457, 95% CI : 0.338–0.618, P < 0.001), and ICU mortality (OR = 0.348, 95% CI : 0.241–0.501, P < 0.001). Similarly, patients receiving high-dose statin therapy also showed significantly reduced risks of 28-day (P < 0.001), 90-day (P = 0.004), in-hospital (P = 0.025), and ICU mortality (P = 0.011). Furthermore, patients with AMI-AKI treated with simvastatin and standard-dose statin therapy exhibited the greatest risk reduction in mortality.

Additionally, we evaluated potential effect modification by stratified variables on the association between statin use and mortality. Significant interactions were observed between antiplatelet agents and statin use, as well as between CHF and statin use (P for interaction < 0.05), suggesting that the use of antiplatelet agents attenuated the protective effect of statins, and that the protective effect of statins was more pronounced in patients without CHF. In the analysis of 28-day mortality, significant interactions were found between CABG and statin use, and between beta-blockers and statin use, indicating that patients undergoing CABG or receiving beta-blockers derived greater benefit from statin therapy. For 90-day mortality, a significant interaction was identified between age and statin use (P for interaction < 0.05), suggesting a stronger protective effect of statins in AMI-AKI patients aged ≤ 65 years. Furthermore, although no significant interaction was detected between AKI stage and statin use, a consistently observed pattern across mortality endpoints was that statins did not demonstrate significant benefit in AMI patients with AKI stages 1 or 2; however, the protective effect was more pronounced in patients with AKI stage 3(see Fig. 5 ). 4. Discussion In this large retrospective cohort study utilizing the MIMIC-IV database, we observed that patients with acute myocardial infarction complicated by acute kidney injury (AMI-AKI) who received statin therapy had a significantly reduced risk of mortality. This protective effect remained statistically significant after multivariable adjustment, propensity score matching (PSM), and inverse probability of treatment weighting (IPTW), and was further corroborated by Kaplan-Meier survival curves. Notably, this association was most pronounced in the simvastatin and atorvastatin subgroups, with the greatest reduction in mortality observed in the standard-dose treatment group. Subgroup analyses revealed that the protective effect of statins was more prominent in AMI patients with stage 3 AKI. Furthermore, patients aged ≤ 65 years, those not receiving antiplatelet agents, those without concurrent chronic heart failure (CHF), those undergoing coronary artery bypass grafting (CABG), or those receiving beta-blocker therapy derived greater benefit from statin treatment. 4.1 Potential Mechanisms Underlying the Reduction in Mortality Associated with Statin Use in AMI-AKI Prior to the present study, the association between statin use and prognosis in patients with AMI-AKI had not been investigated. Our study is the first to reveal that statin therapy is significantly associated with reduced mortality risk in this population. The potential protective mechanisms may involve: (1) activation of endothelial nitric oxide synthase (eNOS) in endothelial cells, increasing nitric oxide (NO) production, thereby ameliorating endothelial dysfunction, promoting vasodilation, and improving renal blood flow [ 22 ] ; (2) inhibition of reactive oxygen species (ROS)-generating enzymes (e.g., NADPH oxidase) and upregulation of the expression and activity of ROS-scavenging enzymes (e.g., catalase and superoxide dismutase), consequently reducing ROS generation and mitigating oxidative stress-induced direct damage to renal vascular endothelial cells and tubular epithelial cells [ 23 ] ; (3) synergistic inhibition of NF-κB activation and NLRP3 inflammasome assembly/activation, thereby reducing the production of key inflammatory cytokines such as interleukins (IL-6, IL-1β) and tumor necrosis factor-alpha (TNF-α), and attenuating renal tubular epithelial cell apoptosis, necrosis, and interstitial fibrosis [ 24 ] ; and (4) upregulation of angiotensin-converting enzyme-2(ACE2) expression within the renin-angiotensin-aldosterone system (RAAS), leading to decreased angiotensin II (Ang II) levels and subsequent inhibition of cell proliferation and renal fibrosis [ 25 ] . 4.2 Differential Efficacy of Statin Types and Dosages in Patients with AMI-AKI This study revealed differential protective effects of various statins in patients with AMI-AKI: simvastatin and atorvastatin were associated with significantly reduced mortality, whereas no such benefit was observed for rosuvastatin or pravastatin. These findings are consistent with previous research:A meta-analysis encompassing 143,888 patients with chronic kidney disease (CKD) demonstrated that atorvastatin, simvastatin, and lovastatin reduced the risk of renal failure, while other statins did not exhibit this effect [ 26 ] . A retrospective study by Li et al. involving 5,376 hospitalized patients with CKD also supported that atorvastatin was particularly effective in improving survival and reducing the risk of AKI [ 27 ] . Furthermore, an animal study confirmed that simvastatin promoted renal functional recovery in mice with sepsis-associated AKI (SA-AKI) by regulating anti-apoptotic molecules [ 28 ] . Conversely, rosuvastatin failed to prevent new-onset AKI or slow the progression of mild kidney injury in critically ill patients with acute respiratory distress syndrome (ARDS) and sepsis [ 29 ] .These discrepancies may be attributable to molecular structural differences: lipophilic statins (e.g., atorvastatin, simvastatin) more easily enter into the tissues by passive diffusion, exhibiting enhanc ed "renophilic" and demonstrating superiority over hydrophilic statins in ameliorating renal pathological damage and restoring renal function [ 30 – 31 ] . Dosage stratification analysis indicated that the risk of mortality was significantly reduced in patients receiving either standard-dose or high-dose statin therapy; however, the magnitude of risk reduction was greatest in those receiving standard-dose statins. This finding suggests that, in the maintenance phase of treatment, standard-dose statins may provide adequate protection while being safer, whereas high-dose regimens, though similarly effective, could potentially increase the risk of dose-related adverse effects. 4.3 Subgroup Analysis Subgroup analysis revealed that the protective effect of statins was more pronounced in patients aged ≤ 65 years, those without concurrent CHF, those not receiving antiplatelet agents, and those undergoing CABG or receiving beta-blocker therapy. Specifically, the age-stratified results are consistent with the research of Xiong et al. [ 14 ] , who found that the risk reduction for AKI associated with statin use was more prominent in obese patients with sepsis under 60 years of age, a finding potentially attributable to better baseline organ function and a lower burden of comorbidities in younger patients. Perioperative aspirin use has been shown to increase bleeding risk without reducing the risk of AKI in patients undergoing major non-cardiac surgery [ 32 ] , which may explain why the protective effect of statins in AMI-AKI patients could be attenuated by concomitant antiplatelet therapy. Statins may also trigger the systemic inflammatory response in patients with CHF [ 33 ] , so AMI-AKI patients without CHF may account for more pronounced benefit from statins.Conversely, the protective effect of statins was particularly prominent in patients undergoing CABG or receiving beta-blocker therapy. This finding may be related to the preoperative use of statins improving postoperative renal function following cardiac surgery [ 31 ] and the potential synergistic effects of beta-blockers with statins in conferring renal protection in patients with AMI [ 34 ] . 4.4 Strengths and Limitations This study was based on the publicly available and comprehensive MIMIC database, ensuring relatively high data reliability and integrity. As the first investigation to explore the association between statin therapy and prognosis in patients with AMI-AKI, we provide clear evidence that statin treatment is associated with a significantly reduced risk of mortality in this population, and further evaluate the impact of different statin types and dosages. These findings offer important insights for optimizing treatment strategies in critically ill patients with AMI-AKI and provide practical evidence for clinical decision-making in the ICU. However, this study has several limitations. First, the MIMIC-IV database predominantly comprises a White population; therefore, extrapolation of these findings to other racial or ethnic groups requires caution. Although the sample size was adequate and relatively representative, multicenter prospective studies are warranted to validate the generalizability of these results. Second, as a single-center retrospective study, despite the use of multivariable adjustment, PSM, and IPTW to control for confounding, potential biases cannot be entirely excluded. Prospective studies are needed to further validate the causal relationship and to comprehensively assess the benefits and risks associated with statin therapy in the future. 5. Conclusion Statin therapy was associated with a significantly reduced risk of mortality in patients with AMI-AKI, with more pronounced benefits observed for simvastatin and standard-dose strategies. This study supports the incorporation of statins into the comprehensive therapeutic management of critically ill patients with AMI-AKI to improve clinical outcomes.

Introduction","content":"\u003cp\u003eAcute myocardial infarction (AMI) is a critical condition resulting from thrombotic occlusion due to coronary plaque rupture or erosion, leading to myocardial ischemic hypoxia injury and necrosis. It can be classified into ST-segment elevation myocardial infarction (STEMI), caused by complete coronary artery occlusion, and non-ST-segment elevation myocardial infarction (NSTEMI), caused by partial or intermittent occlusion. Epidemiological data indicate that the prevalence of AMI is as high as 23.3%, with a mortality rate ranging from 7% to 10%, making it a significant cause of death among patients in intensive care unit (ICU)\u003csup\u003e[\u003cspan citationid=\"CR1\" class=\"CitationRef\"\u003e1\u003c/span\u003e]\u003c/sup\u003e. Acute kidney injury (AKI), a common complication in hospitalized patients with AMI, occurs in 12.1% to 55.6% of cases\u003csup\u003e[\u003cspan citationid=\"CR2\" class=\"CitationRef\"\u003e2\u003c/span\u003e]\u003c/sup\u003e. Its pathogenesis involves multiple pathophysiological processes, including ischemia-reperfusion injury, oxidative stress, inflammation, and nephrotoxicity\u003csup\u003e[\u003cspan additionalcitationids=\"CR4 CR5\" citationid=\"CR3\" class=\"CitationRef\"\u003e3\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR6\" class=\"CitationRef\"\u003e6\u003c/span\u003e]\u003c/sup\u003e. AKI is an independent risk factor affecting both short-term and long-term prognosis in AMI patients, and mortality in patients with concomitant AKI is more than 10 times higher than in those without\u003csup\u003e[\u003cspan citationid=\"CR7\" class=\"CitationRef\"\u003e7\u003c/span\u003e]\u003c/sup\u003e. Therefore, strengthening clinical intervention for AKI following AMI is particularly urgent.\u003c/p\u003e\n\u003cp\u003eStatins, or 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors, are widely used for the primary and secondary prevention of cardiovascular events due to their established lipid-lowering efficacy\u003csup\u003e[\u003cspan citationid=\"CR8\" class=\"CitationRef\"\u003e8\u003c/span\u003e]\u003c/sup\u003e. Their pleiotropic effects, including anti-inflammatory, immunomodulatory, and antioxidant activities, have expanded their potential applications in other diseases\u003csup\u003e[\u003cspan additionalcitationids=\"CR10\" citationid=\"CR9\" class=\"CitationRef\"\u003e9\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e]\u003c/sup\u003e. Studies have shown that statins significantly reduce cardiac and all-cause mortality in patients with AMI\u003csup\u003e[\u003cspan citationid=\"CR12\" class=\"CitationRef\"\u003e12\u003c/span\u003e]\u003c/sup\u003e, and multiple studies have also suggested their ability to lower the risk of developing AKI\u003csup\u003e[\u003cspan additionalcitationids=\"CR14\" citationid=\"CR13\" class=\"CitationRef\"\u003e13\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e15\u003c/span\u003e]\u003c/sup\u003e. Furthermore, a retrospective study by Tang et al. involving 5,376 patients with chronic kidney disease (CKD) reported that statin users had a 55% lower risk of in-hospital mortality compared with non-users\u003csup\u003e[\u003cspan citationid=\"CR16\" class=\"CitationRef\"\u003e16\u003c/span\u003e]\u003c/sup\u003e. A retrospective study by Zheng et al. involving 2,034 patients with AKI also confirmed that statin use was significantly associated with reduced in-hospital mortality, although this association was only statistically significant in the atorvastatin subgroup\u003csup\u003e[\u003cspan citationid=\"CR17\" class=\"CitationRef\"\u003e17\u003c/span\u003e]\u003c/sup\u003e. However, conflicting findings exist: a large cohort study of 43,438 patients reported that statin users had a 30% increased risk of developing AKI compared to non-users\u003csup\u003e[\u003cspan citationid=\"CR18\" class=\"CitationRef\"\u003e18\u003c/span\u003e]\u003c/sup\u003e.

Currently, research on the impact of statins on short-term and long-term outcomes in AMI patients complicated by AKI remains limited.\u003c/p\u003e\n\u003cp\u003eGiven the contradictory nature of the existing evidence and the lack of specific clinical guidelines for statin therapy in this particular patient population, this study utilized real-world data to systematically evaluate the association between statin therapy and clinical outcomes in AMI patients with concomitant AKI, aiming to provide refined, evidence-based support for clinical pharmacotherapy in this group.\u003c/p\u003e\n"},{"header":"2.

Furthermore, the association between different types of statins and mortality was evaluated by examining four commonly used statins: simvastatin, rosuvastatin, pravastatin, and atorvastatin. To further explore the impact of statin dosage on patient mortality, patients were categorized into a standard-dose group and a high-dose group according to the administered statin dose. High-dose statin therapy was defined as a daily dose exceeding the following thresholds: simvastatin 40 mg, rosuvastatin 20 mg, pravastatin 40 mg, and atorvastatin 80 mg\u003csup\u003e[\u003cspan citationid=\"CR21\" class=\"CitationRef\"\u003e21\u003c/span\u003e]\u003c/sup\u003e.Patients receiving multiple types of statins or varying doses were excluded to ensure consistency in exposure assessment.\u003c/p\u003e \u003c/div\u003e \u003cdiv id=\"Sec7\" class=\"Section2\"\u003e \u003ch2\u003e2.5 Clinical Outcomes\u003c/h2\u003e \u003cp\u003eThe primary outcome was 28-day mortality.

Non-normally distributed data are expressed as median (interquartile range, IQR) and were analyzed with the Mann-Whitney U test. Categorical variables, presented as frequencies (percentages), were compared using the chi-square or Fisher's exact test, as appropriate.\u003c/p\u003e \u003cp\u003eBased on a directed acyclic graph (DAG), confounding variables requiring adjustment were identified. Only baseline variables influencing both exposure and outcome were included, while post-exposure variables or mediating variables were avoided.\u003c/p\u003e \u003cp\u003eTo mitigate imbalances in baseline characteristics between the two groups, propensity score matching (PSM) and inverse probability of treatment weighting (IPTW) were employed. Specifically, propensity scores (PS) were calculated using a multivariate logistic regression model incorporating all baseline covariates. A 1:1 nearest neighbor matching algorithm with a caliper width of 0.05 and without replacement was applied to generate a matched cohort with comparable baseline characteristics. Simultaneously, stabilized inverse probability weights based on the PS were used to construct two pseudo-populations, with weights truncated at the 1st and 99th percentiles to control extreme values. The balance of covariates after PSM and IPTW was assessed using standardized mean differences (SMD), with |SMD| \u0026lt; 0.1 indicating adequate balance, and visualized using density plots.\u003c/p\u003e \u003cp\u003eCox proportional hazards regression and logistic regression models were constructed in the original, matched, and weighted cohorts to evaluate the association between statin use and patient mortality. The multivariate model incorporates confounding variables including: demographic information (insurance type, race, sex, age, weight, smoking history, alcohol consumption history), vital signs (heart rate, respiratory rate, MAP, SBP, blood oxygen saturation, urine output), laboratory parameters (WBC, platelet count, hemoglobin, BUN, creatinine, RDW, anion gap, INR, APTT, potassium, sodium, calcium), comorbidities (hypertension, CHF, CVD, chronic pulmonary disease, CKD, malignancy, liver disease, diabetes, obesity, hyperlipidemia),severity scores of the disease(CCI, SOFA, OASIS, SAPS II), therapeutic interventions (mechanical ventilation, vasopressor use, CRRT), and medications (beta-blockers, antiplatelet agents, ACEI, ARB). Multicollinearity among variables was assessed using the variance inflation factor (VIF), and variables with VIF\u0026thinsp;\u0026gt;\u0026thinsp;10 were excluded. All variables included in the multivariate Cox regression models had VIF\u0026thinsp;\u0026lt;\u0026thinsp;10 (see Supplementary Fig.\u0026nbsp;5).\u003c/p\u003e \u003cp\u003eKaplan-Meier survival curves were estimated for 28-day and 90-day survival in the non-statin and statin groups within the original, matched, and weighted cohorts, with differences between groups compared using the log-rank test.\u003c/p\u003e \u003cp\u003eIn the original cohort, multivariate Cox and logistic regression models were constructed to assess the association between statin type and dosage with mortality, adjusting for the same variables as described above. Finally, subgroup analyses were performed to evaluate the consistency of the association between statin use and 28-day and 90-day mortality across different patient populations. Stratification was based on age (\u0026gt;\u0026thinsp;65 years or \u0026le;\u0026thinsp;65 years), sex (male or female), weight (\u0026gt;\u0026thinsp;80 kg or \u0026le;\u0026thinsp;80 kg), AKI stage (1, 2, or 3), comorbidities (CVD, CKD, CHF, diabetes, hyperlipidemia), therapeutic interventions (mechanical ventilation, vasopressors, CRRT, CABG), and medications (beta-blockers and antiplatelet agents), with interaction terms introduced for testing.\u003c/p\u003e \u003cp\u003eAll statistical analyses were performed using R software (version 4.5.1).

Specifically, compared to the non-statin group, patients in the statin group had a higher proportion of males and greater body weight. Regarding vital signs, patients receiving statins exhibited relatively higher oxygen saturation and urine output, but lower heart rate and respiratory rate. Laboratory parameters showed that the statin group had relatively higher white blood cell count, hemoglobin, and calcium levels, but lower BUN, creatinine, anion gap and INR. Disease severity scores (including SOFA, OASIS, SAPS II, and CCI) were lower in the statin group compared to the non-statin group. Regarding comorbidities, the statin group had higher proportions of hypertension, chronic pulmonary disease, diabetes, obesity, and hyperlipidemia, but lower proportions of CHF, malignancy, and liver disease. In terms of therapeutic interventions, the number of patients receiving mechanical ventilation on the first day of ICU admission was higher in the statin group, while vasopressor use and CRRT were more common in the non-statin group. Patients in the statin group were more likely to undergo PCI and CABG.

Fig.\u0026nbsp;\u003cspan refid=\"Fig2\" class=\"InternalRef\"\u003e2\u003c/span\u003e). Confounders identified included: age, alcohol consumption history, smoking history, comorbidities (hypertension, CHF, PVD, CVD, chronic pulmonary disease, CKD, malignancy, diabetes, liver disease, obesity, and hyperlipidemia), and disease severity scores (SOFA, SAPS II, OASIS, and CCI). Relevant variables included: vital signs (heart rate, respiratory rate, SBP, DBP, MAP, oxygen saturation, urine output), laboratory parameters (WBC, platelet count, blood glucose, hemoglobin, BUN, creatinine, RDW, anion gap, INR, APTT, potassium, sodium, calcium), therapeutic interventions (mechanical ventilation, vasopressors, CRRT, PCI, CABG), and medications (beta-blockers, antiplatelet agents, ACEI, ARB). No mediators were identified. Confounders were required to be included in the regression models. Furthermore, as relevant variables may also act as confounders, they were considered for inclusion in the models.\u003c/p\u003e \u003c/div\u003e \u003cdiv id=\"Sec12\" class=\"Section2\"\u003e \u003ch2\u003e3.3 Association Between Statin Use and Patient Mortality\u003c/h2\u003e \u003cp\u003eIn unadjusted models, statin use was significantly associated with a reduced risk of 28-day mortality (HR\u0026thinsp;=\u0026thinsp;0.446, 95% CI : 0.387\u0026ndash;0.514, P\u0026thinsp;\u0026lt;\u0026thinsp;0.001), 90-day mortality (HR\u0026thinsp;=\u0026thinsp;0.491, 95% CI : 0.433\u0026ndash;0.556, P\u0026thinsp;\u0026lt;\u0026thinsp;0.001), in-hospital mortality (OR\u0026thinsp;=\u0026thinsp;0.407, 95% CI : 0.342\u0026ndash;0.484, P\u0026thinsp;\u0026lt;\u0026thinsp;0.001), and ICU mortality (OR\u0026thinsp;=\u0026thinsp;0.388, 95% CI : 0.319\u0026ndash;0.471, P\u0026thinsp;\u0026lt;\u0026thinsp;0.001). In multivariable-adjusted models, compared to the non-statin group, patients in the statin group exhibited a 37.9% reduction in 28-day mortality, a 29.0% reduction in 90-day mortality, a 38.8% reduction in in-hospital mortality, and a 46.5% reduction in ICU mortality. The significant protective effect of statins was consistently observed in both the matched and weighted cohorts (see Fig.\u0026nbsp;\u003cspan refid=\"Fig3\" class=\"InternalRef\"\u003e3\u003c/span\u003e).\u003c/p\u003e \u003c/div\u003e \u003cdiv id=\"Sec13\" class=\"Section2\"\u003e \u003ch2\u003e3.4 Kaplan-Meier Survival Curves\u003c/h2\u003e \u003cp\u003eIn the original cohort, patients with AMI-AKI in the statin group demonstrated significantly higher 28-day and 90-day survival rates compared to those in the non-statin group (P\u0026thinsp;\u0026lt;\u0026thinsp;0.001; Fig.\u0026nbsp;\u003cspan refid=\"Fig4\" class=\"InternalRef\"\u003e4\u003c/span\u003eA, B).

The distribution of statin use was as follows: simvastatin (n\u0026thinsp;=\u0026thinsp;247), rosuvastatin (n\u0026thinsp;=\u0026thinsp;163), pravastatin (n\u0026thinsp;=\u0026thinsp;91), and atorvastatin (n\u0026thinsp;=\u0026thinsp;2,092). Table\u0026nbsp;\u003cspan refid=\"Tab3\" class=\"InternalRef\"\u003e3\u003c/span\u003e shows the association between different types of statins and mortality. Compared with the non-statin group, the use of simvastatin and atorvastatin was significantly associated with lower mortality among patients with AMI-AKI. Specifically, patients receiving simvastatin exhibited a 54.5% reduction in 28-day mortality (HR\u0026thinsp;=\u0026thinsp;0.455, 95% CI : 0.315\u0026ndash;0.658, P\u0026thinsp;\u0026lt;\u0026thinsp;0.001), a 42.7% reduction in 90-day mortality (HR\u0026thinsp;=\u0026thinsp;0.573, 95% CI : 0.425\u0026ndash;0.772, P\u0026thinsp;\u0026lt;\u0026thinsp;0.001), a 60.5% reduction in in-hospital mortality (OR\u0026thinsp;=\u0026thinsp;0.395, 95% CI : 0.242\u0026ndash;0.645, P\u0026thinsp;\u0026lt;\u0026thinsp;0.001), and a 71.1% reduction in ICU mortality (OR\u0026thinsp;=\u0026thinsp;0.289, 95% CI : 0.157\u0026ndash;0.534, P\u0026thinsp;\u0026lt;\u0026thinsp;0.001). Atorvastatin also demonstrated a significant protective effect, with reductions of 36.1%, 27.6%, 39.1%, and 35.4% in 28-day, 90-day, ICU, and in-hospital mortality, respectively. However, no significant association with reduced mortality was observed for rosuvastatin or pravastatin (all P\u0026thinsp;\u0026gt;\u0026thinsp;0.05).\u003c/p\u003e \u003cp\u003e \u003cdiv

Significant interactions were observed between antiplatelet agents and statin use, as well as between CHF and statin use (P for interaction\u0026thinsp;\u0026lt;\u0026thinsp;0.05), suggesting that the use of antiplatelet agents attenuated the protective effect of statins, and that the protective effect of statins was more pronounced in patients without CHF. In the analysis of 28-day mortality, significant interactions were found between CABG and statin use, and between beta-blockers and statin use, indicating that patients undergoing CABG or receiving beta-blockers derived greater benefit from statin therapy. For 90-day mortality, a significant interaction was identified between age and statin use (P for interaction\u0026thinsp;\u0026lt;\u0026thinsp;0.05), suggesting a stronger protective effect of statins in AMI-AKI patients aged\u0026thinsp;\u0026le;\u0026thinsp;65 years. Furthermore, although no significant interaction was detected between AKI stage and statin use, a consistently observed pattern across mortality endpoints was that statins did not demonstrate significant benefit in AMI patients with AKI stages 1 or 2; however, the protective effect was more pronounced in patients with AKI stage 3(see Fig.\u0026nbsp;\u003cspan refid=\"Fig5\" class=\"InternalRef\"\u003e5\u003c/span\u003e).\u003c/p\u003e \u003c/div\u003e"},{"header":"4. Discussion","content":"\u003cp\u003eIn this large retrospective cohort study utilizing the MIMIC-IV database, we observed that patients with acute myocardial infarction complicated by acute kidney injury (AMI-AKI) who received statin therapy had a significantly reduced risk of mortality. This protective effect remained statistically significant after multivariable adjustment, propensity score matching (PSM), and inverse probability of treatment weighting (IPTW), and was further corroborated by Kaplan-Meier survival curves. Notably, this association was most pronounced in the simvastatin and atorvastatin subgroups, with the greatest reduction in mortality observed in the standard-dose treatment group. Subgroup analyses revealed that the protective effect of statins was more prominent in AMI patients with stage 3 AKI. Furthermore, patients aged\u0026thinsp;\u0026le;\u0026thinsp;65 years, those not receiving antiplatelet agents, those without concurrent chronic heart failure (CHF), those undergoing coronary artery bypass grafting (CABG), or those receiving beta-blocker therapy derived greater benefit from statin treatment.\u003c/p\u003e \u003cdiv id=\"Sec17\" class=\"Section2\"\u003e \u003ch2\u003e4.1 Potential Mechanisms Underlying the Reduction in Mortality Associated with Statin Use in AMI-AKI\u003c/h2\u003e \u003cp\u003ePrior to the present study, the association between statin use and prognosis in patients with AMI-AKI had not been investigated. Our study is the first to reveal that statin therapy is significantly associated with reduced mortality risk in this population.

These findings are consistent with previous research:A meta-analysis encompassing 143,888 patients with chronic kidney disease (CKD) demonstrated that atorvastatin, simvastatin, and lovastatin reduced the risk of renal failure, while other statins did not exhibit this effect\u003csup\u003e[\u003cspan citationid=\"CR26\" class=\"CitationRef\"\u003e26\u003c/span\u003e]\u003c/sup\u003e.

As the first investigation to explore the association between statin therapy and prognosis in patients with AMI-AKI, we provide clear evidence that statin treatment is associated with a significantly reduced risk of mortality in this population, and further evaluate the impact of different statin types and dosages. These findings offer important insights for optimizing treatment strategies in critically ill patients with AMI-AKI and provide practical evidence for clinical decision-making in the ICU. However, this study has several limitations. First, the MIMIC-IV database predominantly comprises a White population; therefore, extrapolation of these findings to other racial or ethnic groups requires caution. Although the sample size was adequate and relatively representative, multicenter prospective studies are warranted to validate the generalizability of these results. Second, as a single-center retrospective study, despite the use of multivariable adjustment, PSM, and IPTW to control for confounding, potential biases cannot be entirely excluded. Prospective studies are needed to further validate the causal relationship and to comprehensively assess the benefits and risks associated with statin therapy in the future.\u003c/p\u003e \u003c/div\u003e"},{"header":"5.

Statins are widely used for cardiovascular protection, but their effect on AKI remains uncertain. This study aims to investigate the association between statin therapy and the prognosis of critically ill patients with myocardial infarction-related acute kidney injury (AMI-AKI), providing evidence-based support for clinical decision-making.\u003c/p\u003e\n\u003cp\u003eMethods: AMI-AKI patients were extracted from the MIMIC-IV database and divided into a statin group and a non-statin group based on statin use during their intensive care unit (ICU) stay. The primary outcome was 28-day mortality, and secondary outcomes included 90-day mortality, in-hospital mortality, and ICU mortality. Propensity score matching (PSM) and inverse probability of treatment weighting (IPTW) were used to balance baseline differences between groups. Cox proportional hazards models and logistic regression models assessed the association of statin use, statin type, and statin dosage with clinical outcomes. Survival analysis was performed using Kaplan-Meier curves and Log-rank tests, and subgroup analyses were conducted to explore effect heterogeneity.\u003c/p\u003e\n\u003cp\u003eResults: A total of 3,844 AMI-AKI patients were included, of whom 72.6% received statin therapy during their ICU stay. Multivariable model results showed that statin use was significantly associated with reduced risks of 28-day mortality (HR = 0.621, 95% CI : 0.529-0.729), 90-day mortality (HR = 0.710, 95% CI : 0.617-0.816), in-hospital mortality (OR = 0.612, 95% CI : 0.489-0.767), and ICU mortality (OR = 0.535, 95% CI : 0.414-0.691). These associations remained significant after PSM and IPTW adjustments. Patients receiving simvastatin and standard-dose therapy showed the greatest reduction in mortality. Subgroup analysis revealed that the protective effect of statins was particularly pronounced in patients with AKI stage 3, age ≤65 years, those not using antiplatelet drugs, those without concomitant chronic heart failure (CHF), those undergoing coronary artery bypass grafting (CABG), or those receiving beta-blockers.\u003c/p\u003e\n\u003cp\u003eConclusion: Statin therapy is significantly associated with lower mortality risk in AMI-AKI patients, particularly with simvastatin and standard-dose strategies. This study supports integrating statins into the comprehensive treatment for critically ill AMI-AKI patients to improve clinical outcomes.\u003c/p\u003e","manuscriptTitle":"Prognostic Value of Statins in Critically Ill Patients with Acute Myocardial Infarction-Related Acute Kidney Injury: A Retrospective Cohort Study Based on the MIMIC-IV Database","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2026-04-23 16:26:57","doi":"10.21203/rs.3.rs-9118734/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"reviewerAgreed","content":"60783294309314156285330028745499836237","date":"2026-04-23T13:20:48+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2026-04-20T04:13:41+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"118485495046177873317695093642988187331","date":"2026-04-16T08:41:59+00:00","index":"hide","fulltext":""},{"type":"reviewersInvited","content":"","date":"2026-04-16T07:28:48+00:00","index":"","fulltext":""},{"type":"editorInvited","content":"","date":"2026-03-16T11:22:22+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2026-03-14T07:34:15+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2026-03-14T07:33:59+00:00","index":"","fulltext":""},{"type":"submitted","content":"BMC Cardiovascular Disorders","date":"2026-03-14T01:02:34+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"
