Background and objective: In China, coronary heart disease (CHD) is growing to be the leading cause of mortality due to an increased life expectancy and changes in lifestyle, translating into a substantial financial burden on the health care system. Extensive clinical and statistical studies have identified several risk factors that increase the risk of coronary heart disease and heart attack. Some of them could be modified, treated or controlled, such as cigarette smoking, dyslipidemia, hypertension, and diabetes mellitus. But their prevalence has not yet been precisely determined in patients with established CHD. There are inconsistent concepts regarding to the prevalence of risk factors as different criteria adopted and population studied. Moreover,Most data on the incidence and prevalence of risk factors are based on western countries, It has never been fully evaluated in China ; Secondary prevention in clinical practice has been proven effective in reducing the composite end points of death, myocardial infarction, and stroke . Patients with established coronary artery disease represent an important cohort in whom secondary prevention is likely to be particularly useful and cost-effective. There is growing evidence highlighting the importance of controlling modifiable risk factors for CHD patients in secondary prevention therapy. But surveys reveal that individuals with CHD always have their...
