Importance:Dyslipidemia, the prevalence of which historically has been low in China, is emerging as the second leading yet often unaddressed factor associated with the risk of cardiovascular diseases. However, recent national data on the prevalence, treatment, and control of dyslipidemia are lacking.Objective:To assess the prevalence, treatment, and control of dyslipidemia in community residents and the availability of lipid-lowering medications in primary care institutions in China.Design, Setting, and Participants:This cross-sectional study used data from the China-PEACE (Patient-Centered Evaluative Assessment of Cardiac Events) Million Persons Project, which enrolled 2 660 666 community residents aged 35 to 75 years from all 31 provinces in China between December 2014 and May 2019, and the China-PEACE primary health care survey of 3041 primary care institutions. Data analysis was performed from June 2019 to March 2021.Exposures:Study period.Main Outcomes and Measures:The main outcome was the prevalence of dyslipidemia, which was defined as total cholesterol greater than or equal to 240 mg/dL, low-density lipoprotein cholesterol (LDL-C) greater than or equal to 160 mg/dL, high-density lipoprotein cholesterol (HDL-C) less than 40 mg/dL, triglycerides greater than or equal to 200 mg/dL, or self-reported use of lipid-lowering medications, in accordance with the 2016 Chinese Adult Dyslipidemia Prevention Guideline.Results:This study included 2 314 538 participants with lipid measurements (1 389 322 women [60.0%]; mean [SD] age, 55.8 [9.8] years). Among them, 781 865 participants (33.8%) had dyslipidemia. Of 71 785 participants (3.2%) who had established atherosclerotic cardiovascular disease (ASCVD) and were recommended by guidelines for lipid-lowering medications regardless of LDL-C levels, 10 120 (14.1%) were treated. The overall control rate of LDL-C (≤70 mg/dL) among adults with established ASCVD was 26.6% (19 087 participants), with the control rate being 44.8% (4535 participants) among those who were treated and 23.6% (14 552 participants) among those not treated. Of 236 579 participants (10.2%) with high risk of ASCVD, 101 474 (42.9%) achieved LDL-C less than or equal to 100 mg/dL. Among participants with established ASCVD, advanced age (age 65-75 years, odds ratio [OR], 0.63; 95% CI, 0.56-0.70), female sex (OR, 0.56; 95% CI, 0.53-0.58), lower income (reference category), smoking (OR, 0.89; 95% CI, 0.85-0.94), alcohol consumption (OR, 0.87; 95% CI, 0.83-0.92), and not having diabetes (reference category) were associated with lower control of LDL-C. Among participants with high risk of ASCVD, younger age (reference category) and female sex (OR, 0.58; 95% CI, 0.56-0.59) were associated with lower control of LDL-C. Of 3041 primary care institutions surveyed, 1512 (49.7%) stocked statin and 584 (19.2%) stocked nonstatin lipid-lowering drugs. Village clinics in rural areas had the lowest statin availability.Conclusions and Relevance:These findings suggest that dyslipidemia has become a major public health problem in China and is often inadequately treated and uncontrolled. Statins were available in less than one-half of the primary care institutions. Strategies aimed at detection, prevention, and treatment are needed.

Objective: To understand the awareness, treatment, and control of hypertension in residents aged 35-75 years in eastern China, analyze the treatment mode for antihypertensive agents while identifying those factors affecting awareness, treatment and control. Methods: The data collected in eastern China from the China Patient-Centered Evaluative Assessment of Cardiac Events (PEACE) Million Persons Project were used to obtain the information about the awareness, treatment and control of hypertension in the residents and the antihypertensive medication treatment mode in this area. Multilevel mixed-effects model was used to explore the association of the demographic characteristics of hypertension patients with the rates of awareness, treatment and control of hypertension. Results: A total of 640 539 participants aged 35-75 years, mean age (56.9±9.6) years, were included in the analysis, women accounted for 59.7% and 318 741 (49.8%) of the participants suffered from hypertension. Among those hypertensive patients, 46.5% were aware of their condition, 38.1% were taking prescribed antihypertensive medications, and 11.1% had achieved the control of hypertension, the differences were significant among provinces, between urban area and rural area and among different demographical groups. Calcium-channel blockers was the most commonly used medication (45.1%), and 78 735 hypertension patients (86.2%) took only one type of medication. Older age, higher household income, higher level of education, and histories of myocardial infarction, stroke and diabetes were associated with higher awareness, treatment and control of hypertension (P<0.05). Conclusions: The rates of awareness, treatment and control of hypertension were low in residents in eastern China. The differences in hypertension management were significant among provinces and between urban area and rural area. Further efforts are needed to enhance the system of hypertension prevention, screening, diagnosis and treatment.

Importance:Isolated systolic hypertension (ISH) is increasing in prevalence among young and middle-aged adults. However, most studies of ISH are limited to older individuals, and a substantial knowledge gap exists regarding younger adults with ISH.Objective:To assess the prevalence, awareness, and characteristics of ISH among younger and middle-aged adults in China.Design, Setting, and Participants:This cross-sectional study was performed as part of the China Patient-Centered Evaluative Assessment of Cardiac Events Million Persons Project, which enrolled 3.1 million community residents aged 35 to 75 years from all of the 31 provinces in China between December 15, 2014, and May 15, 2019. The present analysis included only participants younger than 50 years. Data were analyzed from May to November 2019.Main Outcomes and Measures:Prevalence and awareness of ISH (defined as systolic blood pressure of 140 mm Hg or higher and diastolic blood pressure of less than 90 mm Hg) and individual characteristics of participants with ISH.Results:Among 898 929 participants aged 35 to 49 years, the mean (SD) age was 43.8 (3.9) years; 548 657 participants (61.0%) were women, and 235 138 participants (26.2%) had hypertension. Of those with hypertension, 62 819 participants (26.7%; 95% CI, 26.5%-26.9%) had ISH (mean [SD] age, 45.0 [3.5] years; 41 417 women [65.9%]), and 54 463 of those with ISH (86.7%; 95% CI, 86.4%-87.0%) had not received treatment. The prevalence of ISH was higher among individuals who were older, were female, were farmers, resided in the eastern region of China, and had an educational level of primary school or lower. Women and older individuals were more likely to have ISH than to be normotensive or to have other hypertension subtypes. Participants who were obese, currently used alcohol, had diabetes, and experienced previous cardiovascular events were more likely to have other types of hypertension and less likely to have normotension than to have ISH. Among the 54 463 participants with ISH who had not received treatment, only 3682 individuals (6.8%; 95% CI, 6.6%-7.0%) were aware of having hypertension, and awareness rates remained low even among those with systolic blood pressure of 160 mm Hg or higher (7135 individuals [13.1%; 95% CI, 12.4%-13.9%]).Conclusions and Relevance:In this study, ISH was identified in 1 of 4 young and middle-aged adults with hypertension in China, most of whom remained unaware of having hypertension. These results highlight the increasing need for better guidance regarding the management of ISH in this population.

BACKGROUND:Despite the rapid growth in the incidence of acute myocardial infarction (AMI) in China, there is limited information about patients' experiences after AMI hospitalization, especially on long-term adverse events and patient-reported outcomes (PROs).METHODS:The China Patient-centered Evaluative Assessment of Cardiac Events (PEACE)-Prospective AMI Study will enroll 4000 consecutive AMI patients from 53 diverse hospitals across China and follow them longitudinally for 12 months to document their treatment, recovery, and outcomes. Details of patients' medical history, treatment, and in-hospital outcomes are abstracted from medical charts. Comprehensive baseline interviews are being conducted to characterize patient demographics, risk factors, presentation, and healthcare utilization. As part of these interviews, validated instruments are administered to measure PROs, including quality of life, symptoms, mood, cognition, and sexual activity. Follow-up interviews, measuring PROs, medication adherence, risk factor control, and collecting hospitalization events are conducted at 1, 6, and 12 months after discharge. Supporting documents for potential outcomes are collected for adjudication by clinicians at the National Coordinating Center. Blood and urine samples are also obtained at baseline, 1- and 12-month follow-up. In addition, we are conducting a survey of participating hospitals to characterize their organizational characteristics.CONCLUSION:The China PEACE-Prospective AMI study will be uniquely positioned to generate new information regarding patient's experiences and outcomes after AMI in China and serve as a foundation for quality improvement activities.

BACKGROUND:The number of percutaneous coronary interventions (PCI) in China has increased more than 20-fold over the last decade. Consequently, there is a need for national-level information to characterize PCI indications and long-term patient outcomes, including health status, to understand and improve evolving practice patterns.OBJECTIVES:This nationwide prospective study of patients receiving PCI is to: (1) measure long-term clinical outcomes (including death, acute myocardial infarction [AMI], and/or revascularization), patient-reported outcomes (PROs), cardiovascular risk factor control and adherence to medications for secondary prevention; (2) determine patient- and hospital-level factors associated with care process and outcomes; and (3) assess the appropriateness of PCI procedures.METHODS:The China Patient-centered Evaluative Assessment of Cardiac Events (PEACE) Prospective Study of PCI has enrolled 5,000 consecutive patients during 2012-2014 from 34 diverse hospitals across China undergoing PCI for any indication. We abstracted details of patient's medical history, treatments, and in-hospital outcomes from medical charts, and conducted baseline, 1-, 6-, and 12-month interviews to characterize patient demographics, risk factors, clinical presentation, healthcare utilization, and health status using validated PRO measures. The primary outcome, a composite measure of death, AMI and/or revascularization, as well as PROs, medication adherence and cardiovascular risk factor control, was assessed throughout the 12-month follow-up. Blood and urine samples were collected at baseline and 12 months and stored for future analyses. To validate reports of coronary anatomy, 2,000 angiograms are randomly selected and read by two independent core laboratories. Hospital characteristics regarding their facilities, processes and organizational characteristics are assessed by site surveys.CONCLUSION:China PEACE Prospective Study of PCI will be the first study to generate novel, high-quality, comprehensive national data on patients' socio-demographic, clinical, treatment, and metabolic/genetic factors, and importantly, their long-term outcomes following PCI, including health status. This will build the foundation for PCI performance improvement efforts in China. © 2016 The Authors. Catheterization and Cardiovascular Interventions. Published by Wiley Periodicals, Inc.

BACKGROUND:Long-term use of antiplatelet agents, statins, beta-blockers and angiotensin-converting enzyme inhibitors are proven therapies for secondary prevention in acute coronary syndrome. However, little is known of physicians' opinion about their use in China.METHODS:In 2010, standard questionnaires were posted to chief cardiologists in 1397 geographically diverse and representative sample of tertiary and secondary hospitals in China, collecting information about their opinions on the recommended treatments for acute coronary syndrome.RESULTS:A total of 1009 (72%) cardiologists responded with a valid questionnaire. Of them, 77% reported routine use of all the four main secondary preventive treatments, with little difference between secondary and tertiary hospitals (75% vs. 79%, P = 0.16). Of the cardiologists reporting routine or selective use of aspirin, beta-blockers, statins and angiotensin-converting enzyme inhibitors, 94%, 85%, 73% and 86% would recommend indefinite use respectively. For all the 4 treatments combined, only 63.5% reported indefinite use at the same time, with no significant difference between secondary and tertiary hospitals (62% vs. 65%, P = 0.17), nor between hospitals with or without fast track for primary percutaneous coronary intervention (66% vs. 61%, P = 0.50).CONCLUSIONS:Although Chinese cardiologists seem well informed about the value of main secondary preventive treatments for acute coronary syndrome, there is still gap in their understanding of the need for combined and prolonged use of these treatments.

OBJECTIVE:To investigate the current statin use among high-risk patients with atherosclerotic cardiovascular diseases in Chinese large hospitals.METHODS:Clinical history and current medication were recorded in 11 783 patients with a history of atherosclerotic cardiovascular disease (CVD) from 39 highest-ranking hospitals in 10 Chinese cities.RESULTS:Indication for statin use was given for all screened patients and statin was not prescribed in up to 59.6% (7022) patients. For patients with statin use, medication time was shorter than their atherosclerotic CVD history in 1120 (23.5%) patients. The proportion of statin use among patients with ischemic stroke was 19.6%, among patients with coronary heart disease without ischemic stroke was 59.2%.CONCLUSION:Statin is underused in secondary prevention among patients with atherosclerotic CVD in China. There is a large gap between guideline recommended statin use and in practice. Thus, it remains a major challenge for healthcare professionals and policy makers to resolve this problem rapidly.

OBJECTIVE:To investigate the degree and determinants of the use on statin among patients with atherosclerotic ischemic stroke in China.METHODS:In the context of an international multi-center clinical trial being undertaken in China, 5585 patients with atherosclerotic ischemic stroke were screened in 39 prestigious hospitals in 10 cities. The characteristics collected through electronic questionnaire were described and analyzed.RESULTS:All the screened patients had indications for statins. Among those, 60% of the patients had a history from 3 months to 2 years of suffering from stroke. However, up to 80% of the patients were not using statins when screened. Even in those with statins, about 1/4 of the patients took statins for much shorter period than the history of stroke. The proportion using statins among IS patients with CHD was 4 times more than in those without CHD. Simvastatin and Atorvastatin were most commonly used.CONCLUSION:Statins were greatly underused for secondary prevention among patients with atherosclerotic ischemic stroke in China. There was a large gap between evidence and practice. It remains a major challenge for healthcare professionals and policy makers to tackle this problem more positively.
