    Abstract: The genetic contribution to coronary artery disease (CAD) remains largely unclear. We combined genetic screening with functional characterizations to identify novel loci and candidate genes for CAD. Approach and Results— We performed genome-wide screening followed by multicenter validation in 8 cohorts consisting of 21 828 participants of Han ethnicity and identified 3 novel intragenic SNPs (single nucleotide polymorphisms), rs9486729 ( SCML4 [Scm polycomb group protein-like 4]; odds ratio, 1.25; 95% CI, 1.17–1.34; P =3.51×10 −11 ), rs17165136 ( THSD7A [thrombospondin type 1 domain-containing 7A]; odds ratio 1.28; 95% CI, 1.21–1.35; P 〈 1.00×10 −25 ), and rs852787 ( DAB1 [disabled-1]; odds ratio, 1.29; 95% CI, 1.21–1.38; P =2.02×10 −14 ), associated with CAD with genome-wide significance. The risk allele of rs9486729 and protective allele of rs17165136 were associated with the decreased expression of their host genes, SCML4 and THSD7A , respectively, whereas rs852787 did not have transcriptional effects on any gene. Knockdown of SCML4 activated endothelial cells by increasing the expression of IL-6 , E-selectin , and ICAM and weakened their antiapoptotic activity, whereas the knockdown of THSD7A had little effect on these endothelial cell functions but attenuated monocyte adhesion via decreasing the expression of ICAM , L-selectin , and ITGB2 . We further showed that inhibiting the expression of SCML4 exacerbated endothelial dysfunction and vascular remodeling in a rat model with partial carotid ligation. Conclusions— We identify 3 novel loci associated with CAD and show that 2 genes, SCML4 and THSD7A , make functional contributions to atherosclerosis. How rs852787 and its host gene DAB1 are linked to CAD needs further studies.

    Abstract: Multiple genetic loci associated with lipid levels have been identified predominantly in Europeans, and the issue of to what extent these genetic loci can predict blood lipid levels increases over time and the incidence of future hyperlipidemia remains largely unknown. Methods and Results— We conducted a meta-analysis of genome-wide association studies of lipid levels in 8344 subjects followed by replication studies including 14 739 additional individuals. We replicated 17 previously reported loci. We also newly identified 3 Chinese-specific variants in previous regions ( HLA-C , LIPG , and LDLR ) with genome-wide significance. Almost all the variants contributed to lipid levels change and incident hyperlipidemia 〉 8.1-year follow-up among 6428 individuals of a prospective cohort study. The strongest associations for lipid levels change were detected at LPL , TRIB1 , APOA1-C3-A4-A5 , LIPC , CETP , and LDLR ( P range from 4.84×10 −4 to 4.62×10 −18 ), whereas LPL , TRIB1 , ABCA1 , APOA1-C3-A4-A5 , CETP , and APOE displayed significant strongest associations for incident hyperlipidemia ( P range from 1.20×10 −3 to 4.67×10 −16 ). The 4 lipids genetic risk scores were independently associated with linear increases in their corresponding lipid levels and risk of incident hyperlipidemia. A C -statistics analysis showed significant improvement in the prediction of incident hyperlipidemia on top of traditional risk factors including the baseline lipid levels. Conclusions— These findings identified some evidence for allelic heterogeneity in Chinese when compared with Europeans in relation to lipid associations. The individual variants and those cumulative effects were independent risk factors for lipids increase and incident hyperlipidemia.

    Abstract: Although multiple genetic markers associated with blood pressure have been identified by genome-wide association studies, their aggregate effect on risk of incident hypertension and cardiovascular disease is uncertain, particularly among East Asian who may have different genetic and environmental exposures from Europeans. We aimed to examine the association between genetic predisposition to higher blood pressure and risk of incident hypertension and cardiovascular disease in 26 262 individuals in 2 Chinese population-based prospective cohorts. A genetic risk score was calculated based on 22 established variants for blood pressure in East Asian. We found the genetic risk score was significantly and independently associated with linear increases in blood pressure and risk of incident hypertension and cardiovascular disease ( P range from 4.57×10 –3 to 3.10×10 –6 ). In analyses adjusted for traditional risk factors including blood pressure, individuals carrying most blood pressure–related risk alleles (top quintile of genetic score distribution) had 40% (95% confidence interval, 18–66) and 26% (6–45) increased risk for incident hypertension and cardiovascular disease, respectively, when compared with individuals in the bottom quintile. The genetic risk score also significantly improved discrimination for incident hypertension and cardiovascular disease and led to modest improvements in risk reclassification for cardiovascular disease (all the P 〈 0.05). Our data indicate that genetic predisposition to higher blood pressure is an independent risk factor for blood pressure increase and incident hypertension and cardiovascular disease and provides modest incremental information to cardiovascular disease risk prediction. The potential clinical use of this panel of blood pressure–associated polymorphisms remains to be determined.

    Abstract: With rapid socioeconomic development and transition, associations between socioeconomic status (SES) and hypertension remained uncertain in China. We aimed to examine the health effects of SES on hypertension incidence and explore the sex differences among Chinese adults. Methods: We included 53 891 participants without hypertension from the China-PAR (Prediction for Atherosclerotic Cardiovascular Disease Risk in China) project. SES was evaluated by education level, occupation prestige, and household monthly per capita income, and categorized into low, medium, and high groups. Hazard ratios and their 95% CIs were calculated using Cox proportional hazards regression models. Results: Compared with high SES, participants with medium SES (hazard ratio, 1.142 [95% CI, 1.068–1.220]) or low SES (hazard ratio, 1.166 [95% CI, 1.096–1.241] ) had increased risks of incident hypertension in multivariate analyses. Interactions between SES and sex on hypertension were observed, with more pronounced adverse effects of lower SES among women. The corresponding hazard ratios (95% CIs) for low SES group were 1.270 (1.155–1.397) for women and 1.086 (0.999–1.181) for men. Effects of occupation prestige on hypertension were the strongest among SES factors. Conclusions: Our study provided the compelling evidence from China that lower SES was associated with incident hypertension and women were more susceptible. These findings will have substantial implications on future hypertension prevention and management, especially among women. Sex-specific approaches are warranted to reduce socioeconomic disparities.

    Abstract: Background: Air pollution ranks the 4th among risk factors responsible for China’s avoidable disease burden. We projected the potential cardiovascular health benefits achievable with sustained air quality improvement in Beijing and all of urban China. Methods: Coronary heart disease (CHD) and stroke mortality and life years gained were projected in adults aged 35-84 years in Beijing and urban China using the Cardiovascular Disease Policy Model-China. We simulated two air quality improvement scenarios from 2015-2030, each achieved gradually over 10 years: 1) the 2008 Beijing Olympics fine particle matter (PM2.5) level of 55 μg/m3, and 2) the World Health Organization (WHO) recommendation of 10 μg/m3. For comparison, we simulated a 50% reduction in active and secondhand smoking and reduction of systolic hypertension to 140 mmHg, each over 5 years. Relative risks of CHD, stroke and all-cause mortality associated with long term PM2.5 exposure were obtained from a meta-analysis of observational studies. Systolic blood pressure and smoking relative risks were estimated from China Multi-provincial Cohort Study. Results: PM2.5 reduction to 2008 Olympic levels in Beijing would reduce stroke deaths by 2.7%, CHD deaths by 7.2% over 2015-2030 and would gain life-years on the order of about a third of that projected for a 50% smoking reduction, and a fourth of that projected for systolic hypertension control (Table). However, achieving more aggressive WHO PM2.5 goal would yield greater life year gains than either tobacco or systolic blood pressure control. Achieving 2008 Olympics levels in urban China would prevent 304,000 stroke deaths, 619,000 CHD deaths, and gain 4.2 million life years over 2015-2030. Conclusions: Air pollution is a leading cardiovascular risk factor in Beijing and all urban China. We projected that lowering air pollution to Beijing Olympics level could prevent about 900,000 cardiovascular deaths and gain about 4.2 million life years in urban China by 2030.

    Abstract: Previous results on the association between lipids and stroke were controversial. We investigated the association of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C ), high-density lipoprotein cholesterol (HDL-C), and triglyceride with stroke. Methods— Six cohort studies in China with 267 500 participants were included. Cox proportional hazards regression models and restricted cubic spline analyses were used to estimate hazard ratios and 95% CIs and explore linear and nonlinear relationships of lipids and stroke, respectively. Results— The median follow-up duration ranged from 6 to 19 years. During 2 295 881 person-years, 8072 people developed stroke. Multivariable adjusted hazard ratios (95% CIs) per 1 mmol/L increase in TC, LDL-C, triglyceride were 1.08 (1.05–1.11), 1.08 (1.04–1.11), 1.07 (1.05-1.09) for ischemic stroke, respectively. Compared with participants with TC 160-199.9 mg/dL, hazard ratios (95% CIs) were 1.43 (1.11–1.85) for hemorrhagic stroke in those with TC 〈 120 mg/dL. Compared with participants with HDL-C 50 to 59.9 mg/dL, hazard ratios (95% CIs) were 1.23 (1.12–1.35), 1.13 (1.04–1.22) for ischemic stroke, and 1.28 (1.10–1.49), 1.17 (1.03–1.33) for hemorrhagic stroke in those with HDL-C 〈 40 and 40 to 49.9 mg/dL, respectively. Restricted cubic spline analyses showed linear relationships of TC and LDL-C, and nonlinear relationships of HDL-C and triglyceride with ischemic stroke (all P 〈 0.001). Hemorrhagic stroke showed linear relationships with TC and HDL-C ( P =0.029 and 〈 0.001 respectively), but no relationship with LDL-C and triglyceride (all P 〉 0.05). Conclusions— TC, LDL-C, and triglyceride showed positive associations with ischemic stroke. The risk of hemorrhagic stroke was higher when TC was lower than 120 mg/dL. LDL-C and triglyceride showed no association with hemorrhagic stroke. The risks of ischemic and hemorrhagic stroke might be higher when HDL-C was lower than 50 mg/dL.

    Abstract: Outdoor air pollution ranks fourth among preventable causes of China’s burden of disease. We hypothesized that the magnitude of health gains from air quality improvement in urban China could compare with achieving recommended blood pressure or smoking control goals. Methods: The Cardiovascular Disease Policy Model–China projected coronary heart disease, stroke, and all-cause deaths in urban Chinese adults 35 to 84 years of age from 2017 to 2030 if recent air quality (particulate matter with aerodynamic diameter ≤2.5 µm, PM 2.5 ) and traditional cardiovascular risk factor trends continue. We projected life-years gained if urban China were to reach 1 of 3 air quality goals: Beijing Olympic Games level (mean PM 2.5 , 55 μg/m 3 ), China Class II standard (35 μg/m 3 ), or World Health Organization standard (10 μg/m 3 ). We compared projected air pollution reduction control benefits with potential benefits of reaching World Health Organization hypertension and tobacco control goals. Results: Mean PM 2.5 reduction to Beijing Olympic levels by 2030 would gain ≈241,000 (95% uncertainty interval, 189 000–293 000) life-years annually. Achieving either the China Class II or World Health Organization PM 2.5 standard would yield greater health benefits (992 000 [95% uncertainty interval, 790 000–1 180 000] or 1 827 000 [95% uncertainty interval, 1 481 00–2 129 000] annual life-years gained, respectively) than World Health Organization–recommended goals of 25% improvement in systolic hypertension control and 30% reduction in smoking combined (928 000 [95% uncertainty interval, 830 000–1 033 000] life-years). Conclusions: Air quality improvement in different scenarios could lead to graded health benefits ranging from 241 000 life-years gained to much greater benefits equal to or greater than the combined benefits of 25% improvement in systolic hypertension control and 30% smoking reduction.

    Abstract: The accurate assessment of individual risk can be of great value to guiding and facilitating the prevention of atherosclerotic cardiovascular disease (ASCVD). However, prediction models in common use were formulated primarily in white populations. The China-PAR project (Prediction for ASCVD Risk in China) is aimed at developing and validating 10-year risk prediction equations for ASCVD from 4 contemporary Chinese cohorts. Methods: Two prospective studies followed up together with a unified protocol were used as the derivation cohort to develop 10-year ASCVD risk equations in 21 320 Chinese participants. The external validation was evaluated in 2 independent Chinese cohorts with 14 123 and 70 838 participants. Furthermore, model performance was compared with the Pooled Cohort Equations reported in the American College of Cardiology/American Heart Association guideline. Results: Over 12 years of follow-up in the derivation cohort with 21 320 Chinese participants, 1048 subjects developed a first ASCVD event. Sex-specific equations had C statistics of 0.794 (95% confidence interval, 0.775–0.814) for men and 0.811 (95% confidence interval, 0.787–0.835) for women. The predicted rates were similar to the observed rates, as indicated by a calibration χ 2 of 13.1 for men ( P =0.16) and 12.8 for women ( P =0.17). Good internal and external validations of our equations were achieved in subsequent analyses. Compared with the Chinese equations, the Pooled Cohort Equations had lower C statistics and much higher calibration χ 2 values in men. Conclusions: Our project developed effective tools with good performance for 10-year ASCVD risk prediction among a Chinese population that will help to improve the primary prevention and management of cardiovascular disease.

    Abstract: To construct a polygenic risk score (PRS) for stroke and evaluate its utility in risk stratification and primary prevention for stroke. Methods Using a meta-analytic approach and large genome-wide association results for stroke and stroke-related traits in East Asians, we generated a combined PRS (metaPRS) by incorporating 534 genetic variants in a training set of 2,872 patients with stroke and 2,494 controls. We then validated its association with incident stroke using Cox regression models in large Chinese population-based prospective cohorts comprising 41,006 individuals. Results During a total of 367,750 person-years (mean follow-up 9.0 years), 1,227 participants developed stroke before age 80 years. Individuals with high polygenic risk had an about 2-fold higher risk of incident stroke compared with those with low polygenic risk (hazard ratio [HR] 1.99, 95% confidence interval [CI] 1.66–2.38), with the lifetime risk of stroke being 25.2% (95% CI 22.5%–27.7%) and 13.6% (95% CI 11.6%–15.5%), respectively. Individuals with both high polygenic risk and family history displayed lifetime risk as high as 41.1% (95% CI 31.4%–49.5%). Individuals with high polygenic risk achieved greater benefits in terms of absolute risk reductions from adherence to ideal fasting blood glucose and total cholesterol than those with low polygenic risk. Maintaining favorable cardiovascular health (CVH) profile could substantially mitigate the increased risk conferred by high polygenic risk to the level of low polygenic risk (from 34.6% to 13.2%). Conclusions Our metaPRS has great potential for risk stratification of stroke and identification of individuals who may benefit more from maintaining ideal CVH. Classification of Evidence This study provides Class I evidence that metaPRS is predictive of stroke risk.
