This study aims to integrate MIMIC-IV clinical data with GBD 2021 data to analyse epidemiological trends and regional differences in stroke among people aged 70 and above, identify key risk factors, and predict future changes in incidence and mortality rates. Methods: The GBD 2021 database provides macro-epidemiological data on global stroke incidence, mortality, prevalence, and disability-adjusted life years (DALYs) from 1990 to 2021, while the MIMIC-IV database provides detailed clinical records for 2,144 stroke patients. Regional differences were assessed using the Socio-Demographic Index (SDI) for stratification. Three core statistical methods were employed: the Estimated Annual Percentage Change (EAPC) to quantify temporal trends in disease indicators, the Bayesian Age-Period-Cohort (BAPC) model to analyse the effects of ageing and predict the disease burden by 2040, and the Multivariate Cox Proportional Hazards Model to assess the impact of clinical risk factors on outcomes. Results: Clinical analysis of 2,144 ICU-treated stroke patients in the MIMIC-IV database revealed significantly higher 28-day mortality in those aged ≥70 years versus younger patients (22.0% vs. 12.7%, p<0.001), driven by heavier comorbidity burdens (hyperlipidaemia: 53.9% vs. 41.8%; diabetes: 36.4% vs. 30.0%) and poorer organ function (SOFA score: 5.0 vs. 4.0, p=0.037). Multivariable Cox regression confirmed age ≥70 years as an independent mortality risk factor (adjusted HR=1.36, 95% CI:1.05-1.76). In parallel, GBD 2021 data showed a 61% global rise in absolute stroke cases (1990-2021), disproportionately affecting Low-middle SDI regions. While High SDI regions achieved declining prevalence (EAPC=−0.53%), Middle SDI regions faced rising rates (EAPC=+0.42%), with East Asia exhibiting the sharpest incidence increase (EAPC=+1.05%). Hypertension dominated global stroke DALYs, followed by high LDL-cholesterol and fasting hyperglycaemia. Projections suggest a continued global decline in incidence and mortality by 2040, albeit at a slowing rate, attributed to accelerating population ageing. Conclusion: Significant regional disparities in the burden of stroke among the elderly are closely related to the level of the SDI and modifiable risk factors. High-SDI regions have reduced the burden of stroke through advanced intervention measures; Low-middle SDI regions urgently need strategic investment. stroke elderly population global burden of disease risk factors population ageing Figures Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Figure 6 Figure 7 Figure 8 Introduction Stroke has become a major challenge in the field of global public health. According to the latest report from the World Stroke Organisation, the global economic burden of stroke exceeds 890 billion US dollars (accounting for 0.66% of global GDP). From 1990 to 2021, the economic burden of stroke (measured by absolute case numbers) has significantly increased (stroke incidence increased by 70.0%, stroke mortality increased by 44.0%, stroke prevalence increased by 86.0%, and disability-adjusted life years (DALYs) increased by 32%), with approximately 85% of cases occurring in low- and middle-income countries [ 1 ] . Notably, age-specific epidemiological data indicate that the incidence of stroke is significantly higher in individuals aged 70 years and older compared to those aged 60–69 years [ 2 ] . This age-related increase in risk is associated with multiple pathophysiological mechanisms, including endothelial dysfunction, impaired blood-brain barrier integrity, and enhanced neuroinflammatory responses [ 3 ] . Currently, global population ageing is altering the epidemiological characteristics of stroke. Previous studies have shown that the clustering of traditional risk factors in people aged 70 and above has been on the rise from 1990 to 2020, and has been proven to significantly affect the risk of stroke in the elderly population [ 4 – 6 ] . More notably, age-specific risk factors such as frailty syndrome and polypharmacy are significantly associated with poor outcomes [ 7 , 8 ] . It is important to note that the burden of stroke exhibits marked regional disparities, which are closely linked to socioeconomic development. The Socio-Demographic Index (SDI), a composite indicator integrating per capita income, educational attainment, and fertility rates, provides a valuable framework for understanding these disparities [ 9 ] . Regions with different SDI levels (ranging from low to high) show distinct patterns in stroke incidence, mortality, and risk factor profiles, reflecting the influence of healthcare infrastructure, public health policies, and living conditions on disease outcomes [ 10 ] . Most existing epidemiological studies analyse the population aged over 60 as a whole [ 11 ] , and the Global Burden of Disease study has not yet systematically assessed the risk factor attribution scores for the population aged 70 and above [ 12 ] . In addition, there is a lack of long-term prediction models that take population structure changes into account [ 13 ] . Therefore, this study fills the research gap in the epidemiology of stroke in the elderly population based on MIMIC-IV and GBD 2021 data and provides scientific reference for stroke prevention and control in the global ageing society. Methodologies and materials Data sources The MIT Computational Physiology Laboratory established and maintained the large-scale MIMIC-IV database, which contained health-related data used in this retrospective investigation. This database contains comprehensive, excellent medical records of patients hospitalized to the Beth Israel Deaconess Medical Center's intensive care units. The authors were obliged to complete the training course to obtain access to the database. All clinical data for stroke patients were obtained from the MIMIC-IV database (See Appendix for the discharge process flow chart). Data on stroke from 1990 to 2021 were retrieved using the Global Health Data Exchange (GHDx) query tool. The dataset included information on mortality, incidence, and disability-adjusted life years (DALYs), as well as potential risk factors for stroke. The research methods used by the GBD have been extensively described in the existing literature. The SDI is a composite indicator that integrates per capita income distribution with the educational attainment of individuals aged 15 and older to represent regional economic conditions [ 9 ] . The SDI is scored on a scale from 0 to 1, with higher values indicating greater socioeconomic development. The regional classification based on SDI includes five categories: low ( 0.81) [ 14 ] . Statistical analysis Data are presented as mean ± standard deviation (SD) for normally distributed continuous variables or median [interquartile range, IQR] for non-normally distributed variables, and as frequencies (percentages) for categorical variables. Normality of distribution was assessed using the Shapiro-Wilk test. Group comparisons were performed using the chi-square test or Fisher's exact test for categorical variables, and the unpaired t-test or Mann-Whitney U test for continuous variables as appropriate. In the MIMIC - IV cohort, regarding the 28 - day mortality, we initially compared the Kaplan - Meier (K-M) survival curves. Subsequently, a multivariate Cox proportional hazards regression analysis was performed. Four sequential models were constructed: Model 1 (unadjusted), Model 2 (adjusted for gender and body mass index (BMI)), Model 3 (additionally adjusted for comorbidities based on Model 2), and Model 4 (comprehensively adjusted for demographic characteristics, comorbidities, organ failure scores, and vital signs). In GBD data, in order to analyze changes in Crude Rate (CR) over time, we utilized Estimated Annual Percentage Change (EAPC) values. The EAPC was determined using the formula y = α + βx + ε, where y represents the natural logarithm of the CR and x corresponds to the calendar year. Subsequently, the EAPC was calculated as 100 × (exp(β) − 1). A positive EAPC and its corresponding 95% confidence intervals (CIs) signifies an increasing trend in CR, whereas a negative EAPC and its corresponding 95% CIs indicate a decreasing trend in CR. For future burden prediction (up to 2040), we used Bayesian Age Period Queue (BAPC) model and Ensemble Nested Laplacian Approximation (INLA). This model decomposes time changes into age, period, and cohort effects, and generates predictions with 95% uncertainty intervals (UI) through Monte Carlo simulation. Risk factor attribution analysis is based on the GBD comparative risk assessment framework, which visualizes the percentage of attribution of 21 risk factors to stroke DALYs through heat maps MIMIC-IV analysis was conducted using R 4.5.0 software (survival package for Cox regression, ggplot2 package for plotting), while GBD analysis was based on R 4.5.0 (INLA package for running BAPC model, gbdR package for data processing) and WHO Health Equity Assessment Kit (HEAT). Results Clinical Characteristics of Elderly Stroke Patients (≥ 70 Years Old) The study included 2,144 stroke patients admitted to the intensive care unit (ICU), stratified according to the key age threshold of 70 years (Table 1 ). Baseline characteristics revealed significant differences between the elderly group (≥ 70 years old, n = 1,242) and the non-elderly group (< 70 years old, n = 902). Critically ill elderly stroke patients exhibited significantly higher comorbidity burdens, including type 2 diabetes (36.4% vs 30.0%, p = 0.002), CKD (27.5% vs 15.6%, p < 0.001), hyperlipidaemia (53.9% vs 41.8%, p < 0.001), and AHF (41.5% vs 24.5%, p < 0.001). At ICU admission, elderly patients presented with greater disease severity, evidenced by elevated organ failure scores: SOFA (median 5.0 vs 4.0, p = 0.037), SAPS II (42 vs 33, p < 0.001), and OASIS (35 vs 32, p < 0.001). This translated to poorer short-term outcomes, with higher in-hospital mortality (16.3% vs 12.2%, p = 0.008), ICU mortality (11.1% vs 8.1%, p = 0.021), and 28-day mortality (22.0% vs 12.7%, p < 0.001; Fig. 1 ). These findings highlight that ≥ 70-year-old stroke patients requiring ICU care constitute a high-risk subgroup with amplified resource demands due to compounded comorbidities and severity (Fig. 2 ).

Prevalence of Key Comorbidities. B. Stratification of Disease Severity Indices Multivariable-adjusted hazard of 28-day mortality in elderly stroke patients Table 2 presents the multivariate Cox regression analysis of 28-day mortality in critically ill stroke patients. After full adjustment for clinical confounders in Model 4 (including organ failure scores, vital signs, and comorbidities), age ≥ 70 years remained independently associated with increased mortality risk, with an adjusted hazard ratio (HR) of 1.36 (95% CI: 1.05–1.76; p = 0.018). This elevated mortality risk, combined with extended resource utilization observed in elderly ICU patients (such as higher disease severity scores and comorbidity burden, as well as longer ICU stays), suggests amplified healthcare costs for this subgroup.

Trends diverged regionally: High SDI regions showed the steepest decline (EAPC = -0.53%), contrasting with increased rates in Middle SDI regions (EAPC = + 0.42%). East Asia saw a 61% rise in crude incidence rate (CIR) – equivalent to an EAPC of + 1.05%. Mortality improvements were significant globally (EAPC = -1.75%), with high-income Asia Pacific achieving exceptional progress (EAPC = -4.3%), reducing mortality to 28% of its 1990 level. Low SDI regions lagged (EAPC = -0.81%), and sub-Saharan Africa faced persistent high burdens. Alarmingly, Southern sub-Saharan Africa recorded rising DALY rates (EAPC = + 0.63%).

the global stroke burden showed significant temporal trends, as shown in Fig. 3 . crude prevalence rate (CPR), CIR, crude death rate (CDR), and DALYs all exhibited an overall downward trend across all SDI regions (High, Middle, and Low). However, the absolute burden for men has consistently been higher than that for women, indicating the persistent influence of gender differences in stroke risk. Notably, the extent of decline also varies across different SDI regions. The decline was most pronounced in High SDI regions, while Low SDI regions showed some improvement but still had a high baseline burden, highlighting the inequitable distribution of healthcare resources. Despite the overall improvement in global indicators, the burden of stroke increases exponentially with age. High SDI regions partially offset the risks associated with ageing through more effective interventions (such as hypertension management and acute-phase treatment), while low SDI regions, due to limited medical resources, saw a slower decline in the disease burden among the elderly population. The interaction between population ageing and regional development disparities continues to reshape the distribution of disease burden, and improvements over time have not fully eliminated the combined negative effects of age and SDI. 2021 Global Burden of Disease Distribution Map Figure 4 illustrates the global distribution of the prevalence, incidence, mortality, and DALY rate of stroke among the elderly population in 2021. The highest prevalence was in Botswana, the highest incidence was in Uzbekistan, Tajikistan, and Belarus, the highest mortality was in Montenegro and Serbia, and the highest DALY rate was in Montenegro and North Macedonia. A. Prevalence Rate. B. Incidence Rate. C. Mortality Rate. D. Disability-Adjusted Life Years (DALYs) Rate Age group and SDI regional stratification analysis Age-related trends and sociodemographic differences in incidence rates, mortality rates, and DALYs across High, Middle, and Low SDI regions are shown in Fig. 5 . All SDI regions exhibit a consistent upward trend in incidence rates with increasing age. However, the rates of increase vary significantly, with High SDI regions showing a relatively slower upward trend, while Low SDI regions exhibit a steeper upward trend. Mortality rates align with incidence trends, showing an upward trend across all SDI strata with increasing age. Significant differences exist in mortality rates, with Low SDI regions consistently recording the highest mortality rates. DALYs exhibit a progressive increase with age, reflecting the worsening of the disease burden. Notably, the accumulation of DALYs is slower in High SDI regions, while Low SDI regions exhibit a steeper upward trend. Ranking of risk factors Figure 6 shows the percentage of health loss attributable to various risk factors among individuals aged 70 and above in 2021, as a proportion of total DALYs. In most regions, high systolic blood pressure is the primary risk factor contributing to health loss, with values nearly uniformly at 10 across all regions, indicating its highly significant impact. High LDL cholesterol and high fasting plasma glucose also have a significant impact in most regions, with values typically ranging from 8 to 10. Low temperature, particularly in regions such as East Asia and Eastern Europe, has a notable impact, with values reaching 7 or higher. Diet-related factors, such as insufficient intake of whole grains, vegetables, and fruits, also have significant values in some regions. In regions such as East Asia, Eastern Europe, and Central Asia, the impact of hypertension, high LDL cholesterol, and high fasting plasma glucose is particularly pronounced, with values often reaching 10. In regions such as South Asia and Sub-Saharan Africa, the impact of tobacco, low temperature, and diet-related factors is relatively greater. Age-period-cohort effects and the role of ageing mechanisms Age-related biological cumulative effects are manifested by upward trends in both longitudinal and cross-sectional age curves, indicating that stroke incidence and mortality rates increase exponentially with age. This may reflect the cumulative effects of vascular aging and multiple comorbidities (Table 1 and Fig. 6 ), and also confirms that aging is an independent risk factor for stroke (Table 2 and Fig. 5 ), associated with age-related pathophysiological changes. However, societal progress moderates the impact of aging, with the decline in period RR and cohort RR reflecting how medical advancements and public health interventions have reduced stroke risk among age-matched populations over time. Specifically, later-born cohorts have lower risks even at advanced ages compared to earlier-born cohorts. However, in the progression of aging and societal progress, local drift increases are observed in older age groups (e.g., ≥ 80 years), suggesting that the physiological decline caused by ageing may eventually outweigh the benefits of medical interventions. Furthermore, the period bias reached its peak between 2000 and 2010, corresponding to the period of accelerated global ageing, reflecting the lag in the healthcare system's response to sudden changes in population structure. Additionally, cohort effects reveal early-life exposure patterns, with a decline in fitted cohort models suggesting that reduced risk in recent cohorts may be associated with improved early-life nutrition and reduced childhood infections. Specific details can be seen in Fig. 7 . Forecast for 2021–2040 It is projected that the global burden of stroke will undergo significant changes from 2021 to 2040, with varying trends across different indicators. Figure 8 (A) and Fig. 8 (B) present the actual data on stroke incidence and mortality rates among individuals aged 70 and above from 1990 to 2021, as well as the projected trends beyond 2021. The data indicate that both incidence and mortality rates have shown a declining trend over the past 31 years, and are projected to continue declining in the future, though the rate of decline may gradually slow. By 2040, the lowest incidence and mortality rates are projected for the 70–74 age group (Death predictions and incidence predictions in supplementary materials). A. Incidence Rate. B. Mortality Rate. Discussion The global burden of stroke among adults aged 70 and older vividly illustrates the complex interplay between intrinsic ageing mechanisms and late-life diseases, as emphasised by Partridge [ 15 ] and his team. While advances in public health have extended lifespan, healthy longevity—that is, survival free from severe disability—has not kept pace [ 16 ] , placing unsustainable economic pressure on healthcare systems. Our MIMIC-IV analysis validated this disparity: elderly stroke patients faced significantly higher mortality rates (22.0% vs 12.7%, p < 0.001), more severe comorbidities, and over twice the length of ICU stays (median 7.3 days vs 3.1 days), directly leading to increased treatment costs per episode (estimated average medical costs per stroke ranging from 5,798.15 to 140,048 euros [ 17 ] ). This clinical vulnerability results in sustained high burdens, particularly in resource-limited settings, where over 90% of stroke deaths occur [ 18 ] . Crucially, irreversible ageing processes—vascular stiffening, cellular ageing, systemic inflammation [ 19 – 21 ] —interact with modifiable risk factors (e.g., hypertension, Fig. 6 ), further exacerbating the disease burden. By 2019, global stroke-related costs had exceeded 721 billion dollars [ 22 ] , with the economic burden particularly severe among those aged ≥ 70 years due to long-term disability care. However, research on the burden among the elderly population remains limited. Therefore, we integrated MIMIC-IV clinical models with GBD 2021 data to quantify global differences in incidence, mortality, and DALYs across different SDI strata, analyse the contribution of ageing to burden growth, and identify region-specific risk mitigation pathways. This study confirmed significant differences in stroke burden across regions with varying levels of SDI, with stroke prevalence and mortality rates being lower in High SDI regions compared to Low-middle SDI regions—a finding consistent with the results of Li et al.'s study [ 10 ] . This gradient difference likely reflects more developed medical infrastructure, more effective prevention programmes, and higher public awareness in High SDI regions [ 23 , 24 ] . Particularly concerning is the situation in East Asia, where the stroke incidence rate among adults aged 70 and older surged by 61% between 1990 and 2021 (EAPC + 1.05%), far exceeding the global downward trend (EAPC − 0.11%). This anomaly stems from a ‘double burden’: accelerated population ageing (e.g., 29% of the population aged 65 and older in Japan, 14% in China [ 25 ] ) and persistent metabolic risks (hypertension, hyperlipidaemia, and dietary patterns). Crucially, ageing leads to microcirculatory dysfunction and arteriosclerosis [ 26 ] , providing a pathological basis for stroke even in the absence of high-risk exposure. Hypertension and metabolic syndrome represent a cluster of risk phenotypes. In East Asian populations, the prevalence of arterial hypertension (35–45%) and visceral obesity is significantly elevated—both of which are closely associated with insulin resistance [ 27 ] —thereby forming a unique risk profile. Our MIMIC-IV analysis revealed this synergistic effect: elderly stroke patients commonly exhibit a ‘metabolic triad’ of hyperlipidaemia (53.9%), hypertension (53.1%), and type 2 diabetes (36.4%). This convergence accelerates the progression of atherosclerosis, primarily through physiological and pathological mechanisms such as plaque instability, blood flow obstruction, thrombosis, and plaque proliferation [ 28 – 30 ] . In the elderly population, these pathophysiological mechanisms exacerbate age-related vascular fragility, leading to increased stroke incidence and mortality. The MONICA project confirmed that the synergistic effect of smoking and hypertension is a key driver of incidence differences [ 31 ] . Crucially, the context of ‘ageing before affluence’ in East Asia exacerbates these risks—as reflected in our MIMIC-IV cohort by higher disease severity: SOFA score [5.0 (3.0–7.0) vs. 4.0 (2.0–7.0), p = 0.037], and increased in-hospital mortality (16.3% vs. 12.2%, p = 0.008). Our research indicates that elevated systolic blood pressure is the primary risk factor for stroke-related health loss in the global elderly population—a finding attributable to rapid urbanisation, changes in dietary patterns (such as high sodium intake), and insufficient physical activity [ 26 ] . This conclusion was validated by MIMIC-IV data: 53.1% of elderly stroke patients had hypertension, and the 28-day mortality risk for hypertensive patients was 63% higher than for non-hypertensive patients (adjusted hazard ratio [aHR] = 1.63, 95% confidence interval [CI]: 1.29–2.05). The Global Stroke Registry (despite methodological heterogeneity in definitions and time points) consistently validated hypertension as the primary risk factor (prevalence range: 45%-72%), followed by diabetes (18%-40%) and smoking (15%-35%) [ 32 – 34 ] . Notably, synergistic risk factors in specific environments warrant attention. Metabolic synergism primarily involves high LDL cholesterol and fasting blood glucose (particularly significant in East Asia and Eastern Europe, see Fig. 6 ), while environmental-behavioural risks primarily involve smoking and exposure to low environmental temperatures (particularly critical in South Asia and Sub-Saharan Africa). Although crude mortality rates increase with age among adults aged 70 and older, longitudinal data indicate a declining trend in relative risk—this paradox can be attributed to medical advancements such as endovascular thrombectomy [ 35 ] and community-based hypertension management programmes [ 36 ] . However, the GBD 2021 projections warn that the declining trend in mortality rates will slow due to accelerated population ageing, a trend exacerbated by the dual impact of COVID-19. During the COVID-19 pandemic, healthcare systems collapsed (with a 39% reduction in stroke imaging studies [ 37 ] , a 50–70% decrease in global hospitalisation rates [ 38 ] , and a 32% increase in delayed treatment [ 39 ] ; reduced emergency medical service calls related to stroke were associated with excess mortality [ 40 ] ); second, direct biological stimulation (severe COVID patients had a 3-fold increased risk of ischaemic stroke [ 41 ] ). This multidimensional crisis, stemming from resource allocation, avoidance of medical care, and virus-induced thrombosis, highlights critical vulnerabilities in an ageing society. Our research findings reveal a dual challenge. Population ageing will inevitably lead to an absolute increase in stroke incidence, while the long-term care needs of stroke survivors will place pressure on the healthcare system. This necessitates the establishment of a comprehensive ‘prevention-emergency care-rehabilitation’ management system [44, 45] , with priority intervention measures including strengthening community-based primary prevention (e.g., hypertension screening), optimising regional acute care networks (e.g., thrombectomy centres), and promoting cost-effective innovative measures (e.g., AI-guided remote rehabilitation [ 42 , 43 ] ). From an economic perspective, this burden will be exacerbated by the conflict between increasing rehabilitation needs and a declining working-age population (15–64 years) [48] . While the adoption of thrombolytic therapy has controlled costs per case, demographic pressures will increase cumulative expenditures by 40–60% by 2050 [ 12 ] . Therefore, developing equitable, cost-effective strategies, particularly resource allocation based on SDI stratification, is critical for sustainable stroke care. This study provides the first systematic assessment of stroke burden in the population aged ≥ 70 years, addressing a critical research gap. However, several limitations should be noted: the GBD estimates may underrepresent true disease burden in some regions, while the single-center MIMIC-IV data carry selection bias; the risk factor analysis omitted genetic markers and emerging environmental exposures; and the predictive models didn't account for public health emergencies. Future studies should integrate multi-source longitudinal data with molecular epidemiological approaches to better elucidate the biological mechanisms of aging-related stroke. Conclusion There are significant regional differences in the disease burden of stroke among the global elderly population, which is closely related to SDI and exposure to controllable risk factors. High SDI regions have significantly reduced the disease burden through advanced medical interventions, while Low-middle SDI regions urgently need strategic investment in two core areas (optimisation of medical resources, scaling up prevention programmes, and cost-effective innovation, etc.).

According to the latest report from the World Stroke Organisation, the global economic burden of stroke exceeds 890\u0026nbsp;billion US dollars (accounting for 0.66% of global GDP). From 1990 to 2021, the economic burden of stroke (measured by absolute case numbers) has significantly increased (stroke incidence increased by 70.0%, stroke mortality increased by 44.0%, stroke prevalence increased by 86.0%, and disability-adjusted life years (DALYs) increased by 32%), with approximately 85% of cases occurring in low- and middle-income countries\u003csup\u003e[\u003cspan citationid=\"CR1\" class=\"CitationRef\"\u003e1\u003c/span\u003e]\u003c/sup\u003e.

crude prevalence rate (CPR), CIR, crude death rate (CDR), and DALYs all exhibited an overall downward trend across all SDI regions (High, Middle, and Low).

Notably, the extent of decline also varies across different SDI regions.

High LDL cholesterol and high fasting plasma glucose also have a significant impact in most regions, with values typically ranging from 8 to 10. Low temperature, particularly in regions such as East Asia and Eastern Europe, has a notable impact, with values reaching 7 or higher. Diet-related factors, such as insufficient intake of whole grains, vegetables, and fruits, also have significant values in some regions. In regions such as East Asia, Eastern Europe, and Central Asia, the impact of hypertension, high LDL cholesterol, and high fasting plasma glucose is particularly pronounced, with values often reaching 10.

This may reflect the cumulative effects of vascular aging and multiple comorbidities (Table\u0026nbsp;\u003cspan refid=\"Tab1\" class=\"InternalRef\"\u003e1\u003c/span\u003e and Fig.\u0026nbsp;\u003cspan refid=\"Fig6\" class=\"InternalRef\"\u003e6\u003c/span\u003e), and also confirms that aging is an independent risk factor for stroke (Table\u0026nbsp;\u003cspan refid=\"Tab2\" class=\"InternalRef\"\u003e2\u003c/span\u003e and Fig.\u0026nbsp;\u003cspan refid=\"Fig5\" class=\"InternalRef\"\u003e5\u003c/span\u003e), associated with age-related pathophysiological changes. However, societal progress moderates the impact of aging, with the decline in period RR and cohort RR reflecting how medical advancements and public health interventions have reduced stroke risk among age-matched populations over time. Specifically, later-born cohorts have lower risks even at advanced ages compared to earlier-born cohorts. However, in the progression of aging and societal progress, local drift increases are observed in older age groups (e.g., \u0026ge;\u0026thinsp;80 years), suggesting that the physiological decline caused by ageing may eventually outweigh the benefits of medical interventions. Furthermore, the period bias reached its peak between 2000 and 2010, corresponding to the period of accelerated global ageing, reflecting the lag in the healthcare system's response to sudden changes in population structure. Additionally, cohort effects reveal early-life exposure patterns, with a decline in fitted cohort models suggesting that reduced risk in recent cohorts may be associated with improved early-life nutrition and reduced childhood infections.

However, research on the burden among the elderly population remains limited. Therefore, we integrated MIMIC-IV clinical models with GBD 2021 data to quantify global differences in incidence, mortality, and DALYs across different SDI strata, analyse the contribution of ageing to burden growth, and identify region-specific risk mitigation pathways.\u003c/p\u003e\u003cp\u003eThis study confirmed significant differences in stroke burden across regions with varying levels of SDI, with stroke prevalence and mortality rates being lower in High SDI regions compared to Low-middle SDI regions\u0026mdash;a finding consistent with the results of Li et al.'s study\u003csup\u003e[\u003cspan citationid=\"CR10\" class=\"CitationRef\"\u003e10\u003c/span\u003e]\u003c/sup\u003e.

Particularly concerning is the situation in East Asia, where the stroke incidence rate among adults aged 70 and older surged by 61% between 1990 and 2021 (EAPC\u0026thinsp;+\u0026thinsp;1.05%), far exceeding the global downward trend (EAPC \u0026minus;\u0026thinsp;0.11%). This anomaly stems from a \u0026lsquo;double burden\u0026rsquo;: accelerated population ageing (e.g., 29% of the population aged 65 and older in Japan, 14% in China\u003csup\u003e[\u003cspan citationid=\"CR25\" class=\"CitationRef\"\u003e25\u003c/span\u003e]\u003c/sup\u003e) and persistent metabolic risks (hypertension, hyperlipidaemia, and dietary patterns).

Our MIMIC-IV analysis revealed this synergistic effect: elderly stroke patients commonly exhibit a \u0026lsquo;metabolic triad\u0026rsquo; of hyperlipidaemia (53.9%), hypertension (53.1%), and type 2 diabetes (36.4%).

Crucially, the context of \u0026lsquo;ageing before affluence\u0026rsquo; in East Asia exacerbates these risks\u0026mdash;as reflected in our MIMIC-IV cohort by higher disease severity: SOFA score [5.0 (3.0\u0026ndash;7.0) vs. 4.0 (2.0\u0026ndash;7.0), p\u0026thinsp;=\u0026thinsp;0.037], and increased in-hospital mortality (16.3% vs. 12.2%, p\u0026thinsp;=\u0026thinsp;0.008).\u003c/p\u003e\u003cp\u003eOur research indicates that elevated systolic blood pressure is the primary risk factor for stroke-related health loss in the global elderly population\u0026mdash;a finding attributable to rapid urbanisation, changes in dietary patterns (such as high sodium intake), and insufficient physical activity\u003csup\u003e[\u003cspan citationid=\"CR26\" class=\"CitationRef\"\u003e26\u003c/span\u003e]\u003c/sup\u003e. This conclusion was validated by MIMIC-IV data: 53.1% of elderly stroke patients had hypertension, and the 28-day mortality risk for hypertensive patients was 63% higher than for non-hypertensive patients (adjusted hazard ratio [aHR]\u0026thinsp;=\u0026thinsp;1.63, 95% confidence interval [CI]: 1.29\u0026ndash;2.05).

This study aims to integrate MIMIC-IV clinical data with GBD 2021 data to analyse epidemiological trends and regional differences in stroke among people aged 70 and above, identify key risk factors, and predict future changes in incidence and mortality rates.\u0026nbsp;\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eMethods: \u003c/strong\u003eThe GBD 2021 database provides macro-epidemiological data on global stroke incidence, mortality, prevalence, and disability-adjusted life years (DALYs) from 1990 to 2021, while the MIMIC-IV database provides detailed clinical records for 2,144 stroke patients. Regional differences were assessed using the Socio-Demographic Index (SDI) for stratification. Three core statistical methods were employed: the Estimated Annual Percentage Change (EAPC) to quantify temporal trends in disease indicators, the Bayesian Age-Period-Cohort (BAPC) model to analyse the effects of ageing and predict the disease burden by 2040, and the Multivariate Cox Proportional Hazards Model to assess the impact of clinical risk factors on outcomes.\u0026nbsp;\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eResults: \u003c/strong\u003eClinical analysis of 2,144 ICU-treated stroke patients in the MIMIC-IV database revealed significantly higher 28-day mortality in those aged ≥70 years versus younger patients (22.0% vs. 12.7%, p\u0026lt;0.001), driven by heavier comorbidity burdens (hyperlipidaemia: 53.9% vs. 41.8%; diabetes: 36.4% vs. 30.0%) and poorer organ function (SOFA score: 5.0 vs. 4.0, p=0.037). Multivariable Cox regression confirmed age ≥70 years as an independent mortality risk factor (adjusted HR=1.36, 95% CI:1.05-1.76). In parallel, GBD 2021 data showed a 61% global rise in absolute stroke cases (1990-2021), disproportionately affecting Low-middle SDI regions. While High SDI regions achieved declining prevalence (EAPC=−0.53%), Middle SDI regions faced rising rates (EAPC=+0.42%), with East Asia exhibiting the sharpest incidence increase (EAPC=+1.05%). Hypertension dominated global stroke DALYs, followed by high LDL-cholesterol and fasting hyperglycaemia. Projections suggest a continued global decline in incidence and mortality by 2040, albeit at a slowing rate, attributed to accelerating population ageing.\u0026nbsp;\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eConclusion: \u003c/strong\u003eSignificant regional disparities in the burden of stroke among the elderly are closely related to the level of the SDI and modifiable risk factors. High-SDI regions have reduced the burden of stroke through advanced intervention measures; Low-middle SDI regions urgently need strategic investment.\u003c/p\u003e","manuscriptTitle":"The Stroke Crisis in Ageing Societies: Global Trends, Risk Factors, and Clinical Validation","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-10-27 14:31:38","doi":"10.21203/rs.3.rs-7589290/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"decision","content":"Revision requested","date":"2025-11-07T11:29:27+00:00","index":"","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-10-28T23:50:37+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"303716571962420890056246601398773481568","date":"2025-10-28T22:30:04+00:00","index":"hide","fulltext":""},{"type":"editorInvitedReview","content":"","date":"2025-10-15T11:13:43+00:00","index":"hide","fulltext":""},{"type":"reviewerAgreed","content":"100368371702043253984092209282499829552","date":"2025-10-13T13:04:45+00:00","index":"hide","fulltext":""},{"type":"reviewersInvited","content":"","date":"2025-10-13T12:14:40+00:00","index":"","fulltext":""},{"type":"editorInvited","content":"","date":"2025-09-17T16:17:32+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2025-09-13T06:23:48+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2025-09-13T06:23:29+00:00","index":"","fulltext":""},{"type":"submitted","content":"BMC Neurology","date":"2025-09-11T07:53:09+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"
