Keywords: coronary heart disease

    (1) age and gender: 40-year-old after the elevated rate of coronary heart disease incidence rate lower than that of men, the women before menopause, after menopause and men are equal.

    (2) hyperlipidemia: In addition to age, lipid metabolism disorder is the most important predictor of coronary heart disease. There is a close relationship between the total cholesterol (TC) and low-density lipoprotein cholesterol (LDLC) level and risk of coronary events. The LDLC level is increased by 1%, 2-3% increase in the risk of CHD. Triglyceride (TG) is an independent predictor of coronary heart disease, often associated with low HDLC and abnormal glucose tolerance, the latter two are also crown heart disease risk factors.

    (3). Hypertension: high blood pressure and coronary atherosclerosis formation and development are closely related. Systolic blood pressure than diastolic blood pressure better predictor of coronary heart disease events .140-149mmhg systolic blood pressure than the 90-94mmhg diastolic blood pressure can help increase the risk of coronary heart disease deaths.

    (4) Smoking: Smoking is an important risk factor for coronary heart disease, is the only most avoidable cause of death. There is a clear dosage – response relationship between coronary heart disease and smoking.

    (5). Diabetes: Coronary heart disease is the primary cause of death of juvenile diabetes, coronary heart disease accounted for nearly 80% of the diabetic patients the cause of death and hospitalization rates.

    (6). Obesity: defined as the primary risk factor for coronary heart disease, increase coronary heart disease mortality. Obesity is defined as a body mass index (BMI = weight (kg) / height squared (m2))> = 27.8 in men and women> = 27.3.BMI with TC, TG increased, HDL-C decreased a positive correlation.

    (7). Sedentary lifestyle: people who do not love sports coronary heart disease and the risk of death doubles.

    (8) there are genetic, alcohol consumption, and environmental factors.
