Abstract

AbstractBackgroundPatients with rheumatoid arthritis (RA) have increased mortality and morbidity due to cardiovascular disease (CVD). Distinguishing RA with CVD, RA with CVD risk factors and patients with RA only (pure RA), is still a challenge. The study aimed to develop a better model to predict the likelihood of CVD in RA.MethodsPure RA (n = 402), RA with CVD risk factors (n = 394), and RA with CVD (n = 201) were ultimately recruited into the study and their peripheral bloods were collected to measure the levels of routine examination indicators, vascular endothelial growth factor (VEGF) and immune cells. Univariate analysis, the least absolute shrinkage and selection operator (LASSO), the random forest (RF) and the logistic regression models (LR) were employed to screen characteristic variables between each two groups, and individualized nomograms were further established to more conveniently predict the likelihood of CVD in RA.ResultsUnivariate analysis showed that the levels of WBC, BUN, creatinine, CK, LDH and VEGF were significantly elevated in RA with CVD, as well as serum TC, TG, LDL, ApoB100 and ApoE, while ApoA1 and HDL/CHOL were decreased. Furthermore, the ratio of Treg cells, exhibiting excellent separation performance, in RA with CVD was significantly lower than that in other groups, while the ratio of Th1/Th2/NK and Treg were significantly elevated. LASSO, RF and LR models were also used to find the risk factors for CVD in RA. Through the final selected indicators screened by three machine learning models and univariate analysis, a convenient nomogram was established for predicting CVD risk in RA.ConclusionsSerum lipids, lipoproteins, and Treg cells have been identified as risk factors for CVD in patients with RA, and three nomograms combining various risk factors were constructed and were used for individualized prediction of CVD in patients with RA (pure RA and/or with CVD risk factors).

The global prevalence of RA is about 0.5-1.0%, while the prevalence of RA in Chinese people is around 0.32 to 0.36%, and RA is not only more common in women (3:1), but they also are usually sicker than men [ 4 ]. So far, although the contribution of genetic predisposition and environmental factors to the pathogenesis of RA has been partially confirmed, the etiology of RA needs to be further explored [ 5 ]. In addition, due to that RA remains often under-prioritized in the early stage, especially in the underprivileged families, patients with RA often arrive at hospital with irreversible joint dysfunction and disability, and are often accompanied by multiple comorbidities that lead to poor clinical outcomes, such as cardiovascular disease (CVD), interstitial pneumonia and anemia [ 6 ]. CVD nowadays has been regarded as the number one cause of morbidity and mortality in the world [ 7 ], and its incidence has elevated by about one third over the past decade [ 8 ], seriously affecting people's quality of life and increase their psychological and economic burden [ 7 , 9 ]. Alarmingly, the prevalence of CVD in autoimmune diseases has been greatly underestimated in recent decades [ 10 ]. Result from a large observational cohort showed that patients with RA experience CV events 1.5-2 fold than the general population, including coronary heart disease (CHD), myocardial infarction (MI), stroke and heart failure [ 11 – 13 ]. Despite the availability of excellent treatment strategy, CV events cause more than half of all deaths in RA patients compared with the healthy population, cancer and respiratory diseases [ 10 , 14 , 15 ]. Consistent with the general population, traditional CVD risk factors, such as hypertension, dyslipidemia, diabetes and smoking and so on, also play an important role in the occurrence and progress of CVD in RA patients [ 16 , 17 ]. In general, the lipid profile that induces the occurrence of CVD is usually high total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C) and low level of high-density lipoprotein cholesterol (HDL-C). In addition, mounting evidence suggests that the chronic inflammatory state of RA patients from the early stage also holds the position of an dominant player contributing to the increased morbidity and progression of CV complications, explaining the premature onset of cardiovascular disease in RA [ 18 , 19 ]. Elevated C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) have been shown to be involved in the development of CVD [ 20 ]. And pro-inflammatory cells and cytokines implicated in RA also contribute to CVD. In addition, endothelial dysfunction and some medications are also regarded as the key inducer of CVD. Lack of attention to the disease in RA, especially in developing countries, leads to a higher incidence of comorbidities, especially CVD. As CV events is hidden in the early stage, it is often ignored by people, resulting in irreversible consequences. Therefore, an RA specific CVD risk assessment tool needs to be developed to facilitate clinicians to take preventive measures. In general, we can prevent or alleviate the risk of CVD using existing screening methods and interventions. Multiple cardiovascular risk models have been built to predict the likelihood of CVD in individuals, such as Framingham risk score (FRS), the Systematic Coronary Risk Evaluation (SCORE), and 2013 American College of Cardiology/American Heart Association CVD Risk Score, but these models tend to underestimate the risk of CVD in RA patients due to their limited indicators, resulting in some individuals cannot be accurately identified [ 21 ]. Therefore, hypertension, dyslipidemia, smoking, obesity, immune molecules and other biological indicators need to be explored to refine the CVD risk assessment model for RA patients so that timely preventive strategies can be adopted. In this study, a variety of machine learning methods were used to incorporate blood routine index, serological indicators and multiple lymphocyte subsets to explore the factors influencing the occurrence of CVD in RA, and predictive nomograms were established to identify RA with CVD, RA with CVD risk factors, and patients with RA only (pure RA). Materials and methods Study design and population The retrospective study recruited 1535 RA patients (1030 females, 505 males, median age 57.58 ± 9.84 years) who met the 2010 American College of Rheumatology/European League Against Rheumatology classification criteria for RA and were diagnosed by 2 clinicians at the Second Hospital of Shanxi Medical University from January 2016 to December 2019. Disease activity of RA was evaluated according to the disease activity score 28-erythrocyte sedimentation rate (DAS28-ESR) [ 22 ]. Individuals with one or more of the following conditions were excluded from the study: 1) under 18 years of age (n = 64); 2) with pregnancy (n = 28); 3) with neoplastic diseases (n = 52); 4) with other autoimmune diseases (n = 113); 5) with a history of CVD (n = 94); 6) patients who have been prescribed lipid-lowering drugs or non-steroidal anti-inflammatory drugs (NSAIDs) or who have used relatively high doses of corticosteroids for a long time (n = 187). Out of the remaining 997 RA patients, 402 were pure RA, 394 were RA with CVD risk factors (including hypertension or diabetes or dyslipidemia or fatty liver disease), and 201 were RA with CVD. The category of CVD includes coronary heart disease, coronary atherosclerosis, heart failure, myocardial infarction, and other peripheral vascular diseases. The medical ethics committee of the Second Hospital of Shanxi Medical University has approved the study (2016KY007), and written informed consents were obtained from all patients. Demographic and laboratory data All clinical characteristics of the patients, such as age, sex, body mass index (BMI), smoking, disease duration, and the quantities of tender and swollen joints, were obtained from the medical records of our hospital. In addition, data of routine examination biomarker were also recorded, including blood routine examination [white blood cells (WBC), red blood cells (RBC), hemoglobin (Hb), platelet (PLT), the number and percentage of lymphocyte (LYMP) and neutrophile granulocyte (NEUT)], liver and kidney function indicators [albumin (ALB), alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), glutamyl transferase (GGT), urea, creatinine, cystatin C (CYSC), α1 microglobulin (α1-MG), β2 microglobulin (β2-MG), complement C1q, creatine kinase (CK), and lactate dehydrogenase (LDH)], and lipid indicators, including total cholesterol (CHOL), triglycerides (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), apolipoprotein A1 (ApoA1), apolipoprotein B100 (ApoB100), apolipoprotein E (ApoE), lipoprotein α (LP(α)) and high-density lipoprotein/cholesterol (HDL/CHOL). Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and vascular endothelial growth factor (VEGF) level were also measured. Lymphocyte subsets Peripheral blood specimens were collected from RA patients on the morning of the first day after admission and before medication. CD3+/CD4+/CD8 + T cells were identified by anti-CD3 /CD4/CD8/CD45 antibodies and B/NK cells were labeled by anti-CD3/CD16/CD56/CD45/CD19 antibodies. For Th1/Th2/Th17 cells, we need to stimulate the cells with Ionomycin and PMA for 6 h and then label them with anti-CD4/IFN-γ/IL-4/IL-17 antibodies. In addition, anti-CD4/CD25/FoxP3 antibodies were employed for the identification of Treg cells. Statistical analysis SPSS22.0 and R package were used to analyze the data. One-way ANOVA was used to analyze differences in continuous variables, which was recorded as mean ± standard deviation (SD), among the four groups. Dichotomous variables were compared by the Chi-square test. P value < 0.05 indicated statistical significance between groups. In the study, in addition to univariate analysis, the least absolute shrinkage and selection operator (LASSO), the random forest (RF) and the logistic regression models (LR) were also employed to screen characteristic variables between each two groups (pure RA and/or RA + CVD risk factors vs. RA + CVD). By removing the missing values, a total of 628 patients’ data (241 pure RA, 259 RA + CVD risk factors, 500 RA without CVD, 128 RA + CVD) were finally included in these machine learning (ML) models for analysis. These patients were randomly selected and divided into a training set (75%) for calculation of parameters and construction of models, and a validation set (25%) for model testing and evaluation, where the four groups’ proportions in each set were equal. Ten-fold cross-validation was used in the training set, that is, 9/10 of the data was used to fit the model in turn, and the remaining 1/10 of the data was used for validation, and the process was performed 10 times in total. Finally, the model was tested by the validation set. The step was repeated 10 times randomly (i.e., we completed 10 resampling iterations) so as to obtain the stable result. To ensure the fairness of these models, we used the same data segmentation and repetition to evaluate these models each time. In the process of 10 repetitions, the model with the maximum area under the receiver operating characteristic curve (AU-ROC) was considered to be the best model. Metrics with the top 10 variable important for the projection value (VIP) or weight size were considered as feature variables. The selection criteria of the final important variable was that the indicator had discriminative significance in the three machine learning algorithms and univariate analysis at the same time. Multivariate logistic regression was then used to analyze these screened final significant variables to generate individualized predictive nomograms. Results Clinical characteristics and demographic data of participants Among 997 RA patients, 402 were pure RA (279 females, 123 males, 55.06 ± 12.88 years), 394 were RA with CVD risk factors (262 females, 132 males, 55.13 ± 11.43 years), i.e., 796 were RA without CVD (541 females, 255 males, 55.10 ± 12.18 years) and 201 were RA with CVD (134 females, 67 males, 56.77 ± 8.71 years), of which 126 were coronary heart disease, 41 coronary atherosclerosis, 34 blood clots. No significant differences were observed in age, sex, BMI, disease duration and smoking history among the four groups. Results of univariate analysis showed that levels of VEGF, WBC and AST in RA patients with CVD were significantly higher than those in pure RA and RA without CVD, respectively. LYMP in pure RA and level of TBIL in RA with CVD risk factors were significantly lower than those in RA with CVD. In addition, the serum contents of urea, creatinine, CK, LDH, TC, TG, LDL, ApoB100 and ApoE in RA with CVD were significantly higher than those in pure RA and/or RA with CVD risk factors, while ApoA1 level was reduced ( P < 0.05). Furthermore, the ratio of HDL/CHOL in RA with CVD was obviously elevated compared with RA with CVD risk factors and RA without CVD. The clinical characteristics and demographic data of 997 RA patients were summarized in Table 1 . The alluvial plot (Fig. 1 ) showed the distribution of patients across the disease groups, gender, DAS28-ESR and RA-related autoantibodies. After removing the missing values, remaining 628 patients in all three groups were randomly assigned to a training set (75%) consisted of 181 pure RA, 194 RA with CVD risk factors and 96 RA with CVD, and a validation set (25%) consisted of 60 pure RA, 65 RA with CVD risk factors and 32 RA with CVD. Figure 2 exhibited the study design and analysis scheme. Table 1 Comparison of clinical characteristics and demographic data among pure RA, RA with CVD risk factors, and RA with CVD.

The ratio of NK and Treg cells was obviously lower in RA with CVD risk factors. In addition, the count of NK cells, the ratios of Th1/Th2/NK and Treg in RA without CVD were statistically lower than these indicators in RA with CVD, respectively. Notably, the percentage of Treg cells in pure RA, RA with CVD risk factor, and the overall population of both groups were significantly higher than that in RA with CVD.

Three groups of patients were randomly divided into training set and validation set at a ratio of 3:1. LASSO, RF and LR models were established to identify RA with CVD from pure RA and/or RA with CVD risk factors and filter the corresponding valuable indicators. When identifying the pure RA and the RA with CVD group, the range of AUC of LASSO, RF and LR were 0.79 to 0.91, 0.84 to 0.93, and 0.77 to 0.86, respectively. When distinguishing the RA with CVD from RA with CVD risk factors, the range of AUC of LASSO, RF and LR were 0.61 to 0.77, 0.76 to 0.94, and 0.61 to 0.73, respectively. And when distinguishing RA with CVD from RA without CVD, the range of AUC of LASSO, RF and LR were 0.70 to 0.79, 0.76 to 0.88, and 0.62 to 0.80, respectively (Fig. 3 ). Supplementary Table 1 displayed the top 20 important indicators of the three models when they had the best identifiable performance. Performance ability of the screened important indicators in the diagnosis of RA with CVD Indicators that were simultaneously significant in LASSO, RF, LR and univariate analysis were considered as important indicators. When comparing pure RA patients and RA with CVD, a total of 6 indicators were screened, namely ApoA1, TG, TC, BUN, Th1/Treg and ApoE. LDL, Treg% and TC were considered as important indicators when comparing RA with CVD risk factors and RA with CVD. In addition, in comparison of RA with or without CVD, 6 indicators including TG, LDL, Treg%, TC, CK and ApoE were screened out (Fig. 4). Establishment of a risk prediction model for CVD in individuals with RA Based on the above results, multivariable logistic regression analysis was used to screen for independent predictors, and nomograms were established. Figure 5 showed the score of each predictor, the personal total score and the predicted risk of occurrence CVD for RA. This nomogram (Fig. 5 A) contains 4 independent predictors, TG, TC, BUN and Th1/Treg, when predicting the risk of CVD development from pure RA patients. And LDL and Treg% serve as the independent predictors in the nomogram which predicts the risk of CVD development from RA with CVD risk factors (Fig. 5 B). In addition, the nomogram includes 5 independent predictors, namely TG, LDL, Treg%, CK and ApoE, when predicting the risk of CVD development from all RA patients (Fig. 5 C). These nomograms exhibit good clinical usefulness. Discussion The incidence of CVD, which includes coronary artery disease (CAD) or coronary heart disease (CHD), peripheral artery disease (PAD), cerebrovascular disease and aortic atherosclerosis [ 23 ], is increasing year by year in both developing and developed countries [ 24 ]. It is largely understood that the initiation, progression, and complications of CVD are complex phenomena involving the interplay of the irrational diet, reduced physical activity, abnormal metabolism, dyslipidemia, excessive consumption of alcohol and tobacco and immune system disorders [ 25 ]. In particular, dyslipidemia, which is characterized by elevated levels of plasma TG, LDL, very low-density lipoprotein cholesterol (VLDL-C) and reduced HDL, is confirmed to promote the development of atherosclerotic plaques and occurrence of CVD, posing a serious threat to humans health. Furthermore, several exchangeable apolipoproteins, such as ApoA1, ApoB100, ApoE, and LP(α), have also been shown to play important roles in modulating plasma and cellular lipid metabolism and homeostasis, consequently affecting the emergence of CVD [ 26 ]. RA is a complex systemic autoimmune disease accompanied by poor prognosis, which is characterized by an increased morbidity and mortality of CVD. This increased risk of CVD is apparent even before the clinical diagnosis of RA: subjects with RA have a 1.5-2.0 fold risk to develop CVD than individuals without RA [ 27 ]. And the phenomenon could be attribute to shared inflammatory underpinnings (such as elevated CRP, ESR, rheumatoid factor, and anti-citrullinated protein antibodies), aberrant initiation of an immune response, abnormal changes of serum lipids and lipoproteins, endothelial dysfunction and the use of steroids [ 28 , 29 ]. As is commonly acknowledged, the inflammatory properties inherent in RA not only have the capacity to modify the structure and function of lipoproteins, but also exert direct or indirect effects on vascular architecture [ 30 , 31 ]. Patients diagnosed with RA should be closely monitored for risk factors for CVD, as recommended by EULAR guidelines [ 32 ]. More research, hence, is imperative to fully characterize the intricate mechanism underlying the development of CVD in RA, to screen for characteristic differential biomarkers, and use them to construct and evaluate risk assessment models, prevention and treatment strategies that are tailored specifically for RA [ 31 ]. In the retrospective study, we used real-world data in conjunction with traditional CVD risk factors and RA-related indicators to construct a more robust predictive model of CVD risk in RA patients. The main results of our study showed that the levels of WBC, urea, creatinine, CK, LDH and VEGF were significantly elevated in RA with CVD, as well as serum TC, TG, LDL, ApoB100 and ApoE, while ApoA1 and HDL/CHOL were decreased. VEGF has been reported to promote the occurrence of microvessels in atherosclerotic plaques and increase the possibility of intracatheral hemorrhage and thrombosis. Our results showed that VEGF levels were significantly higher in RA patients with CVD than in pure RA, but lower than that in RA with CVD risk factors, which we hypothesized was because VEGF may play a more crucial role in the process of atherosclerosis than CVD has already occurred. CD4 + CD25 + FOXP3 + Treg cells, recently, has received increasing attention in inflammation and immune regulation. Given that both innate and adaptive immune responses are involved in the initiation and development of CVD, suppressive Treg cells may be crucial for maintaining cardiovascular homeostasis [ 33 , 34 ]. The ratio of Treg cells, in the current study, in RA with CVD was significantly lower than that in other groups, while the ratio of Th1/Treg, Th2/Treg and NK/Treg were significantly elevated, exhibiting excellent separation performance. Nowadays, machine learning are developing rapidly and has been successfully used to diagnose diseases and predict disease onset [ 35 , 36 ]. Various risk calculators, to date, have been utilized to predict the risk of CVD developing, however, none of them seem to perform as effectively in RA patients as they do in the general population [ 37 ]. Numerous scholars, hence, have endeavored to devise and authenticate CVD risk assessment models specifically for RA. An enhanced and recalibrated version of the European Systematic Coronary Risk Evaluation algorithm [ 38 ] (SCORE) was devised for RA patients in the Netherlands [ 39 ]. The novel score incorporated measures of inflammatory disease activity and reevaluated traditional risk factors, yet demonstrated only marginal improvement over its predecessor when applied to individuals with RA. Solomon et al. also built an expanded CVD risk prediction score for RA patients (ERS-RA), which incorporated both traditional CVD risk factors and RA-related indicators such as inflammatory disease activity, disease course, daily prednisone dosage and so on [ 40 ]. Despite its comprehensive nature, the ERS-RA still failed to outperform FRS in external validation. However, as the FRS solely encompasses some conventional risk factors, it may potentially underestimate the CVD risk in patients with RA. Risk models for patients with RA may require the inclusion of factors that differ from or supplement those used in the general population. Recent research has shown that multiple biochemical markers can be analyzed together to create a comprehensive index. Therefore, we then established a novel model that included blood routine index, serum lipid, VEGF and lymphocyte subpopulations, to estimate CVD risk in RA accurately and comprehensively. In this study, LASSO, RF and LR models were used to find the predictive factors for CVD in RA, and ApoA1, TG, TC, BUN, Th1/Treg and ApoE (pure RA vs. RA with CVD), LDL, Treg% and TC (RA with CVD risk factors vs. RA with CVD), and TG, LDL, Treg%, TC, CK and ApoE (RA without CVD vs. RA with CVD) were screened out, respectively. Through the final selected indicators, a convenient nomogram was established for predicting CVD risk in RA, which will greatly promote the individualized risk prediction of CVD in clinical RA patients, providing a very convenient suggestion for clinical practice. The advantage of this study is that it is the first time to integrate serum lipids, lipoproteins and lymphocytes to assess the risk of CVD in RA, providing a certain reference for the prediction and diagnosis of CVD. The information provided in this study can help physicians make more reasonable treatment plans for patients, improve their goal-oriented medical outcomes, and improve the quality of life of patients with RA. Our study, however, still had several limitations. First, this study was performed in a single hospital and the size of the recruited population was limited. Additionally, a lag may be existed in the diagnosis of CVD in the RA. That is, CVD is present before RA. Third, this study had the inevitable limitations of a retrospective study. A prospective study would be required to avoid the interference of these factors. Conclusion In conclusion, serum lipids, lipoproteins, and Treg cells have been identified as risk factors for CVD in patients with RA, and three nomograms were constructed to predict the development of CVD in patients with RA in different backgrounds (pure RA and/or with CVD risk factors). Our study shows that integrated ipidomic profiling and lymphocyte subset analysis is a promising approach to predict the probability of CVD in RA.

The global prevalence of RA is about 0.5-1.0%, while the prevalence of RA in Chinese people is around 0.32 to 0.36%, and RA is not only more common in women (3:1), but they also are usually sicker than men [\u003cspan citationid=\"CR4\" class=\"CitationRef\"\u003e4\u003c/span\u003e]. So far, although the contribution of genetic predisposition and environmental factors to the pathogenesis of RA has been partially confirmed, the etiology of RA needs to be further explored [\u003cspan citationid=\"CR5\" class=\"CitationRef\"\u003e5\u003c/span\u003e]. In addition, due to that RA remains often under-prioritized in the early stage, especially in the underprivileged families, patients with RA often arrive at hospital with irreversible joint dysfunction and disability, and are often accompanied by multiple comorbidities that lead to poor clinical outcomes, such as cardiovascular disease (CVD), interstitial pneumonia and anemia [\u003cspan citationid=\"CR6\" class=\"CitationRef\"\u003e6\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eCVD nowadays has been regarded as the number one cause of morbidity and mortality in the world [\u003cspan citationid=\"CR7\" class=\"CitationRef\"\u003e7\u003c/span\u003e], and its incidence has elevated by about one third over the past decade [\u003cspan citationid=\"CR8\" class=\"CitationRef\"\u003e8\u003c/span\u003e], seriously affecting people's quality of life and increase their psychological and economic burden [\u003cspan citationid=\"CR7\" class=\"CitationRef\"\u003e7\u003c/span\u003e, \u003cspan citationid=\"CR9\" class=\"CitationRef\"\u003e9\u003c/span\u003e]. Alarmingly, the prevalence of CVD in autoimmune diseases has been greatly underestimated in recent decades [\u003cspan citationid=\"CR10\" class=\"CitationRef\"\u003e10\u003c/span\u003e]. Result from a large observational cohort showed that patients with RA experience CV events 1.5-2 fold than the general population, including coronary heart disease (CHD), myocardial infarction (MI), stroke and heart failure [\u003cspan additionalcitationids=\"CR12\" citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR13\" class=\"CitationRef\"\u003e13\u003c/span\u003e]. Despite the availability of excellent treatment strategy, CV events cause more than half of all deaths in RA patients compared with the healthy population, cancer and respiratory diseases [\u003cspan citationid=\"CR10\" class=\"CitationRef\"\u003e10\u003c/span\u003e, \u003cspan citationid=\"CR14\" class=\"CitationRef\"\u003e14\u003c/span\u003e, \u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e15\u003c/span\u003e]. Consistent with the general population, traditional CVD risk factors, such as hypertension, dyslipidemia, diabetes and smoking and so on, also play an important role in the occurrence and progress of CVD in RA patients [\u003cspan citationid=\"CR16\" class=\"CitationRef\"\u003e16\u003c/span\u003e, \u003cspan citationid=\"CR17\" class=\"CitationRef\"\u003e17\u003c/span\u003e]. In general, the lipid profile that induces the occurrence of CVD is usually high total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C) and low level of high-density lipoprotein cholesterol (HDL-C). In addition, mounting evidence suggests that the chronic inflammatory state of RA patients from the early stage also holds the position of an dominant player contributing to the increased morbidity and progression of CV complications, explaining the premature onset of cardiovascular disease in RA [\u003cspan citationid=\"CR18\" class=\"CitationRef\"\u003e18\u003c/span\u003e, \u003cspan citationid=\"CR19\" class=\"CitationRef\"\u003e19\u003c/span\u003e]. Elevated C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) have been shown to be involved in the development of CVD [\u003cspan citationid=\"CR20\" class=\"CitationRef\"\u003e20\u003c/span\u003e]. And pro-inflammatory cells and cytokines implicated in RA also contribute to CVD. In addition, endothelial dysfunction and some medications are also regarded as the key inducer of CVD.\u003c/p\u003e \u003cp\u003eLack of attention to the disease in RA, especially in developing countries, leads to a higher incidence of comorbidities, especially CVD. As CV events is hidden in the early stage, it is often ignored by people, resulting in irreversible consequences. Therefore, an RA specific CVD risk assessment tool needs to be developed to facilitate clinicians to take preventive measures. In general, we can prevent or alleviate the risk of CVD using existing screening methods and interventions. Multiple cardiovascular risk models have been built to predict the likelihood of CVD in individuals, such as Framingham risk score (FRS), the Systematic Coronary Risk Evaluation (SCORE), and 2013 American College of Cardiology/American Heart Association CVD Risk Score, but these models tend to underestimate the risk of CVD in RA patients due to their limited indicators, resulting in some individuals cannot be accurately identified [\u003cspan citationid=\"CR21\" class=\"CitationRef\"\u003e21\u003c/span\u003e]. Therefore, hypertension, dyslipidemia, smoking, obesity, immune molecules and other biological indicators need to be explored to refine the CVD risk assessment model for RA patients so that timely preventive strategies can be adopted.\u003c/p\u003e \u003cp\u003eIn this study, a variety of machine learning methods were used to incorporate blood routine index, serological indicators and multiple lymphocyte subsets to explore the factors influencing the occurrence of CVD in RA, and predictive nomograms were established to identify RA with CVD, RA with CVD risk factors, and patients with RA only (pure RA).\u003c/p\u003e"},{"header":"Materials and methods","content":"\u003cdiv id=\"Sec3\" class=\"Section2\"\u003e \u003ch2\u003eStudy design and population\u003c/h2\u003e \u003cp\u003eThe retrospective study recruited 1535 RA patients (1030 females, 505 males, median age 57.58\u0026thinsp;\u0026plusmn;\u0026thinsp;9.84 years) who met the 2010 American College of Rheumatology/European League Against Rheumatology classification criteria for RA and were diagnosed by 2 clinicians at the Second Hospital of Shanxi Medical University from January 2016 to December 2019.

CVD, as did the proportion and absolute count of Th1 cells, Th2 cells count, and the ratio of Th1/Th2/NK and Treg, respectively. The ratio of NK and Treg cells was obviously lower in RA with CVD risk factors. In addition, the count of NK cells, the ratios of Th1/Th2/NK and Treg in RA without CVD were statistically lower than these indicators in RA with CVD, respectively. Notably, the percentage of Treg cells in pure RA, RA with CVD risk factor, and the overall population of both groups were significantly higher than that in RA with CVD.

Three groups of patients were randomly divided into training set and validation set at a ratio of 3:1. LASSO, RF and LR models were established to identify RA with CVD from pure RA and/or RA with CVD risk factors and filter the corresponding valuable indicators. When identifying the pure RA and the RA with CVD group, the range of AUC of LASSO, RF and LR were 0.79 to 0.91, 0.84 to 0.93, and 0.77 to 0.86, respectively. When distinguishing the RA with CVD from RA with CVD risk factors, the range of AUC of LASSO, RF and LR were 0.61 to 0.77, 0.76 to 0.94, and 0.61 to 0.73, respectively. And when distinguishing RA with CVD from RA without CVD, the range of AUC of LASSO, RF and LR were 0.70 to 0.79, 0.76 to 0.88, and 0.62 to 0.80, respectively (Fig.\u0026nbsp;\u003cspan refid=\"Fig3\" class=\"InternalRef\"\u003e3\u003c/span\u003e).

It is largely understood that the initiation, progression, and complications of CVD are complex phenomena involving the interplay of the irrational diet, reduced physical activity, abnormal metabolism, dyslipidemia, excessive consumption of alcohol and tobacco and immune system disorders [\u003cspan citationid=\"CR25\" class=\"CitationRef\"\u003e25\u003c/span\u003e]. In particular, dyslipidemia, which is characterized by elevated levels of plasma TG, LDL, very low-density lipoprotein cholesterol (VLDL-C) and reduced HDL, is confirmed to promote the development of atherosclerotic plaques and occurrence of CVD, posing a serious threat to humans health. Furthermore, several exchangeable apolipoproteins, such as ApoA1, ApoB100, ApoE, and LP(α), have also been shown to play important roles in modulating plasma and cellular lipid metabolism and homeostasis, consequently affecting the emergence of CVD [\u003cspan citationid=\"CR26\" class=\"CitationRef\"\u003e26\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eRA is a complex systemic autoimmune disease accompanied by poor prognosis, which is characterized by an increased morbidity and mortality of CVD. This increased risk of CVD is apparent even before the clinical diagnosis of RA: subjects with RA have a 1.5-2.0 fold risk to develop CVD than individuals without RA [\u003cspan citationid=\"CR27\" class=\"CitationRef\"\u003e27\u003c/span\u003e]. And the phenomenon could be attribute to shared inflammatory underpinnings (such as elevated CRP, ESR, rheumatoid factor, and anti-citrullinated protein antibodies), aberrant initiation of an immune response, abnormal changes of serum lipids and lipoproteins, endothelial dysfunction and the use of steroids [\u003cspan citationid=\"CR28\" class=\"CitationRef\"\u003e28\u003c/span\u003e, \u003cspan citationid=\"CR29\" class=\"CitationRef\"\u003e29\u003c/span\u003e]. As is commonly acknowledged, the inflammatory properties inherent in RA not only have the capacity to modify the structure and function of lipoproteins, but also exert direct or indirect effects on vascular architecture [\u003cspan citationid=\"CR30\" class=\"CitationRef\"\u003e30\u003c/span\u003e, \u003cspan citationid=\"CR31\" class=\"CitationRef\"\u003e31\u003c/span\u003e]. Patients diagnosed with RA should be closely monitored for risk factors for CVD, as recommended by EULAR guidelines [\u003cspan citationid=\"CR32\" class=\"CitationRef\"\u003e32\u003c/span\u003e]. More research, hence, is imperative to fully characterize the intricate mechanism underlying the development of CVD in RA, to screen for characteristic differential biomarkers, and use them to construct and evaluate risk assessment models, prevention and treatment strategies that are tailored specifically for RA [\u003cspan citationid=\"CR31\" class=\"CitationRef\"\u003e31\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eIn the retrospective study, we used real-world data in conjunction with traditional CVD risk factors and RA-related indicators to construct a more robust predictive model of CVD risk in RA patients. The main results of our study showed that the levels of WBC, urea, creatinine, CK, LDH and VEGF were significantly elevated in RA with CVD, as well as serum TC, TG, LDL, ApoB100 and ApoE, while ApoA1 and HDL/CHOL were decreased. VEGF has been reported to promote the occurrence of microvessels in atherosclerotic plaques and increase the possibility of intracatheral hemorrhage and thrombosis. Our results showed that VEGF levels were significantly higher in RA patients with CVD than in pure RA, but lower than that in RA with CVD risk factors, which we hypothesized was because VEGF may play a more crucial role in the process of atherosclerosis than CVD has already occurred.

Given that both innate and adaptive immune responses are involved in the initiation and development of CVD, suppressive Treg cells may be crucial for maintaining cardiovascular homeostasis [\u003cspan citationid=\"CR33\" class=\"CitationRef\"\u003e33\u003c/span\u003e, \u003cspan citationid=\"CR34\" class=\"CitationRef\"\u003e34\u003c/span\u003e]. The ratio of Treg cells, in the current study, in RA with CVD was significantly lower than that in other groups, while the ratio of Th1/Treg, Th2/Treg and NK/Treg were significantly elevated, exhibiting excellent separation performance.\u003c/p\u003e \u003cp\u003eNowadays, machine learning are developing rapidly and has been successfully used to diagnose diseases and predict disease onset [\u003cspan citationid=\"CR35\" class=\"CitationRef\"\u003e35\u003c/span\u003e, \u003cspan citationid=\"CR36\" class=\"CitationRef\"\u003e36\u003c/span\u003e]. Various risk calculators, to date, have been utilized to predict the risk of CVD developing, however, none of them seem to perform as effectively in RA patients as they do in the general population [\u003cspan citationid=\"CR37\" class=\"CitationRef\"\u003e37\u003c/span\u003e]. Numerous scholars, hence, have endeavored to devise and authenticate CVD risk assessment models specifically for RA. An enhanced and recalibrated version of the European Systematic Coronary Risk Evaluation algorithm [\u003cspan citationid=\"CR38\" class=\"CitationRef\"\u003e38\u003c/span\u003e] (SCORE) was devised for RA patients in the Netherlands [\u003cspan citationid=\"CR39\" class=\"CitationRef\"\u003e39\u003c/span\u003e]. The novel score incorporated measures of inflammatory disease activity and reevaluated traditional risk factors, yet demonstrated only marginal improvement over its predecessor when applied to individuals with RA. Solomon et al. also built an expanded CVD risk prediction score for RA patients (ERS-RA), which incorporated both traditional CVD risk factors and RA-related indicators such as inflammatory disease activity, disease course, daily prednisone dosage and so on [\u003cspan citationid=\"CR40\" class=\"CitationRef\"\u003e40\u003c/span\u003e]. Despite its comprehensive nature, the ERS-RA still failed to outperform FRS in external validation. However, as the FRS solely encompasses some conventional risk factors, it may potentially underestimate the CVD risk in patients with RA. Risk models for patients with RA may require the inclusion of factors that differ from or supplement those used in the general population. Recent research has shown that multiple biochemical markers can be analyzed together to create a comprehensive index. Therefore, we then established a novel model that included blood routine index, serum lipid, VEGF and lymphocyte subpopulations, to estimate CVD risk in RA accurately and comprehensively. In this study, LASSO, RF and LR models were used to find the predictive factors for CVD in RA, and ApoA1, TG, TC, BUN, Th1/Treg and ApoE (pure RA vs. RA with CVD), LDL, Treg% and TC (RA with CVD risk factors vs. RA with CVD), and TG, LDL, Treg%, TC, CK and ApoE (RA without CVD vs. RA with CVD) were screened out, respectively. Through the final selected indicators, a convenient nomogram was established for predicting CVD risk in RA, which will greatly promote the individualized risk prediction of CVD in clinical RA patients, providing a very convenient suggestion for clinical practice.\u003c/p\u003e \u003cp\u003eThe advantage of this study is that it is the first time to integrate serum lipids, lipoproteins and lymphocytes to assess the risk of CVD in RA, providing a certain reference for the prediction and diagnosis of CVD. The information provided in this study can help physicians make more reasonable treatment plans for patients, improve their goal-oriented medical outcomes, and improve the quality of life of patients with RA. Our study, however, still had several limitations. First, this study was performed in a single hospital and the size of the recruited population was limited. Additionally, a lag may be existed in the diagnosis of CVD in the RA. That is, CVD is present before RA. Third, this study had the inevitable limitations of a retrospective study. A prospective study would be required to avoid the interference of these factors.\u003c/p\u003e"},{"header":"Conclusion","content":"\u003cp\u003eIn conclusion, serum lipids, lipoproteins, and Treg cells have been identified as risk factors for CVD in patients with RA, and three nomograms were constructed to predict the development of CVD in patients with RA in different backgrounds (pure RA and/or with CVD risk factors).

Distinguishing RA with CVD, RA with CVD risk factors and patients with RA only (pure RA), is still a challenge. The study aimed to develop a better model to predict the likelihood of CVD in RA.\u003c/p\u003e \u003cp\u003e \u003cb\u003eMethods\u003c/b\u003e Pure RA (n\u0026thinsp;=\u0026thinsp;402), RA with CVD risk factors (n\u0026thinsp;=\u0026thinsp;394), and RA with CVD (n\u0026thinsp;=\u0026thinsp;201) were ultimately recruited into the study and their peripheral bloods were collected to measure the levels of routine examination indicators, vascular endothelial growth factor (VEGF) and immune cells. Univariate analysis, the least absolute shrinkage and selection operator (LASSO), the random forest (RF) and the logistic regression models (LR) were employed to screen characteristic variables between each two groups, and individualized nomograms were further established to more conveniently predict the likelihood of CVD in RA.\u003c/p\u003e \u003cp\u003e \u003cb\u003eResults\u003c/b\u003e Univariate analysis showed that the levels of WBC, BUN, creatinine, CK, LDH and VEGF were significantly elevated in RA with CVD, as well as serum TC, TG, LDL, ApoB100 and ApoE, while ApoA1 and HDL/CHOL were decreased. Furthermore, the ratio of Treg cells, exhibiting excellent separation performance, in RA with CVD was significantly lower than that in other groups, while the ratio of Th1/Th2/NK and Treg were significantly elevated. LASSO, RF and LR models were also used to find the risk factors for CVD in RA. Through the final selected indicators screened by three machine learning models and univariate analysis, a convenient nomogram was established for predicting CVD risk in RA.\u003c/p\u003e \u003cp\u003e \u003cb\u003eConclusions\u003c/b\u003e Serum lipids, lipoproteins, and Treg cells have been identified as risk factors for CVD in patients with RA, and three nomograms combining various risk factors were constructed and were used for individualized prediction of CVD in patients with RA (pure RA and/or with CVD risk factors).\u003c/p\u003e","manuscriptTitle":"Predicting the likelihood of cardiovascular disease in patients with rheumatoid arthritis: development and Validation of a Novel Model","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2023-05-23 14:41:50","doi":"10.21203/rs.3.rs-2914034/v1","editorialEvents":[{"type":"communityComments","content":0}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"researchsquare","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":true,"externalIdentity":"","sideBox":"","snPcode":"","submissionUrl":"/submission","title":"Research Square","twitterHandle":"researchsquare","acdcEnabled":true,"dfaEnabled":false,"editorialSystem":"","reportingPortfolio":"","inReviewEnabled":false,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"bb686c45-6ab4-4afd-8a3c-b144a370a5c5","owner":[],"postedDate":"May 23rd, 2023","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"posted","subjectAreas":[],"tags":[],"updatedAt":"2023-07-16T23:10:14+00:00","versionOfRecord":[],"versionCreatedAt":"2023-05-23 14:41:50","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v1","identity":"rs-2914034","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-2914034","identity":"rs-2914034","version":["v1"]},"buildId":"WrCJVZZCHTDjtuVLN7oU0","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
