BACKGROUND The American Heart Association Committee recently developed definitions of "ideal," "intermediate," and "poor" cardiovascular health based on 7 cardiovascular disease (CVD) risk factors or health behaviors. This study evaluated the prevalence of "ideal" American Heart Association cardiovascular health metrics from June 2006 to October 2007 in the(More)
OBJECTIVES This study aimed to determine the occurrence of cardiovascular (CV) events in a prehypertensive Chinese population. METHODS Participants meeting the JNC 7 diagnostic criteria for prehypertension (n=30,027) and ideal blood pressure (n=15,614) were enrolled in this prospective, observational cohort. New CV events were collected during follow-up(More)
OBJECTIVE To explore the association between body mass index (BMI) and mortality in the middle-aged and elderly population of Beijing. METHODS A prospective cohort study was carried out in a natural population (aged 40 and over) in September 1991, totaling 6 209 subjects. After a baseline survey for risk factors, all the subjects were followed-up(More)
BACKGROUND Data on stroke risk factor profiles and atrial fibrillation (AF) for the Chinese population are sparse. This study identified risk factors for stroke among native Chinese with nonrheumatic AF. METHODS In this retrospective investigation, patients diagnosed with nonrheumatic AF were identified from 18 hospitals in representative areas of the(More)
Cigarette smoking is the leading preventable cause of death worldwide. Few studies, however, have examined the modified effects of age on the association between smoking and all-cause mortality.In the current study, the authors estimated the association between smoking and age-specific mortality in adults from Beijing, China. This is a large community-based(More)
BACKGROUND Intensive atorvastatin may be beneficial for patients with ST segment elevated myocardial infarction (STEMI). However, its effects on endothelial and residual platelet function remain uninvestigated in these patients. METHODS This single-center single-blinded prospective randomized controlled trial included STEMI patients undergoing PCI, aiming(More)
BACKGROUND Blood pressure variability (BPV) is a reliable prognostic factor for cardiovascular events. Currently there is a worldwide lack of large sample size studies in visit-to-visit BPV. Based on the Kailuan Study, we analyzed the visit-to-visit BPV of patients to investigate the range and influencing factors of BPV. METHODS In 11 hospitals in the(More)
BACKGROUND Large-scale clinical trials have shown that routine monitoring of the platelet function in patients after percutanous coronary intervention (PCI) is not necessary. However, it is still unclear whether patients received high-risk PCI would benefit from a therapy which is guided by a selective platelet function monitoring. This explanatory study(More)
BACKGROUND Studies on the association between body mass index (BMI) and death risk among patients with hypertension are limited, and the results are inconsistent. We investigated the association between BMI and cardiovascular disease (CVD) and all-cause mortality among hypertensive patients in a population of Beijing, China. METHODS We conducted a(More)
Given both smoking and vitamin D are associated with coronary heart disease (CHD) via inflammation and smoking may interfere with the local antiinflammatory effects of vitamin D. We hypothesized that the relationship between smoking and severity of CHD may be modified by vitamin D.A cross-sectional study was conducted. 25-OH vitamin D values were determined(More)
