Association Between Hyperhomocysteinemia Combined with Metabolic Syndrome and Higher Prevalence of Stroke in Chinese Adults Who Have Elevated Blood Pressure.

ABSTRACT: BACKGROUND Hyperhomocysteinemia (HHcy) and metabolic syndrome (MS) are established cardiovascular risk factors of stroke and are frequently associated with hypertension. However, studies on the association between HHcy combined with MS and stroke risk in hypertensive patients were absent. MATERIAL AND METHODS In 14 059 selected participants with elevated blood pressure, we assessed the prevalence of the MS and stroke. We defined HHcy as plasma total homocysteine >15 μmol/L. MS was defined according to the Chinese Diabetes Society (CDS) criterion. Multivariable analysis was used to examine the association of HHcy or (and) MS with stroke risk in different models. RESULTS The prevalence rates of HHcy and MS were 49.96% and 42.21%, respectively. Patients with stroke had higher plasma total homocysteine levels and a higher prevalence of MS (P<0.001). Multivariable analyses indicated that HHcy and MS are independently associated with higher prevalence of stroke (adjusted-odds ratio (OR): 1.36, 95% CI 1.17 to 1.58, P<0.001; adjusted-OR: 1.68, 95% CI 1.44 to 1.96, P<0.001, respectively). Those with combined HHcy and MS had higher odds of stroke than those with isolated HHcy or MS (adjusted-OR: 1.78, 95% CI 1.47 to 2.15, P<0.001; adjusted-OR: 1.39, 95% CI 1.13 to 1.70, P=0.002, respectively). CONCLUSIONS HHcy combined with MS was associated with higher prevalence of stroke in Chinese adults with elevated blood pressure.

Project description:BackgroundElevated blood pressure (BP) is associated with substantial morbidity and mortality in stroke survivors. China has the highest prevalence of stroke survivors and accounts for one-third of stroke-related deaths worldwide. We aimed to describe the prevalence and treatment of elevated BP across age, sex, and region, and assess the mortality attributable to elevated BP among stroke survivors in China.Materials and methodsBased on 3,820,651 participants aged 35-75 years from all 31 provinces in mainland China recruited from September 2014 to September 2020, we assessed the prevalence and treatment of elevated BP (systolic BP ≥ 140 mmHg or diastolic BP ≥ 90 mmHg) among those with self-reported stroke and stratified by age group, sex, and geographic region. We estimated the age- and sex-specific population attributable fractions of death from elevated BP.ResultsAmong 91,406 stroke survivors, the mean (SD) age was 62 (8) years, and 49.0% were male. The median interquartile range (IQR) stroke duration was 4 (2, 7) years. The prevalence of elevated BP was 61.3% overall, and increased with age (from 47.5% aged 35-44 years to 64.6% aged 65-75 years). The increment of prevalence was larger in female patients than male patients. Elevated BP was more prevalent in northeast (66.8%) and less in south (54.3%) China. Treatment rate among patients with elevated BP was 38.1%, and rates were low across all age groups, sexes, and regions. Elevated BP accounted for 33 and 21% of cardiovascular and all-cause mortality among stroke survivors, respectively. The proportion exceeded 50% for cardiovascular mortality among patients aged 35-54 years.ConclusionIn this nationwide cohort of stroke survivors from China, elevated BP and its non-treatment were highly prevalent across all age groups, sexes, and regions. Elevated BP accounted for nearly one-third cardiovascular mortality in stroke survivors, and particularly higher in young and middle-aged patients. National strategies targeting elevated BP are warranted to address the high stroke burden in China.

Project description:ImportanceAlthough cumulative evidence suggests that higher blood pressure (BP) and a greater burden of social determinants of health (SDOH) are associated with an increased risk of stroke, few studies have examined whether SDOH burden modifies the association between BP and stroke risk.ObjectiveTo evaluate whether the association between BP classification and stroke risk differs by SDOH burden among Chinese adults.Design, setting, and participantsIn this cohort study, analyses were conducted among 90 850 participants in the prospective subcohort of the China Patient-Centered Evaluative Assessment of Cardiac Events Million Persons Project, with recruitment from January 1, 2016, to December 31, 2020. Participants without cardiovascular diseases and with complete data were included and followed up for stroke events until June 30, 2023.ExposuresSocial determinants of health burden was defined using 5 components: educational attainment, economic stability, health care access, social support, and urban vs rural residence. Blood pressure was categorized according to the 2017 American College of Cardiology/American Heart Association BP guideline.Main outcomes and measuresMultivariable Cox proportional hazards regression was used to estimate hazard ratios (HRs) and 95% CIs for associations of BP classification with incident stroke stratified by SDOH burden groups.ResultsThe study included 90 850 participants (median age, 54.0 years [IQR, 46.0-62.0 years]; 55 390 women [61.0%]). During a median follow-up of 5.0 years (IQR, 4.1-5.8 years), 4408 incident stroke events were recorded. Compared with normal BP, elevated BP (HR, 1.33 [95% CI, 1.17-1.52]), stage 1 hypertension (HR, 1.60 [95% CI, 1.43-1.78]), and stage 2 hypertension (HR, 1.79 [95% CI, 1.61-2.00]) were associated with stroke among participants with high SDOH burden, while only stage 2 hypertension (HR, 1.52 [95% CI, 1.20-1.93]) was associated with stroke among those with low SDOH burden, with a significant multiplicative interaction of SDOH burden and BP classification (P = .03). Participants with high SDOH burden and stage 2 hypertension had the highest risk of stroke compared with participants with low SDOH burden and normal BP (HR, 2.13 [95% CI, 1.75-2.60]).Conclusions and relevanceThis study suggests that higher BP levels, even at lower stages of hypertension, pose a greater stroke risk for individuals with high SDOH burden. Early surveillance and intervention for high BP should be emphasized in socioeconomically disadvantaged populations.
