[Study on relativity of sudden death from CHD to risk factor of cardiovascular disease]

The relativity of the incidence rate of sudden death from coronary heart disease (CHD) among 2,990,816 people from 1985 to 1989 and the risk factor of cardiovascular disease was studied. The result showed that the crude incidence rate of sudden death from CHD was 12/100,000, standardized incidence rate 11.1/100,000 (according to the population in 1982), 9.5/100,000 (according to the population in 1964), was positive correlation with the mean level of blood pressure, prevalence rate of hypertension, total cholesterol in serum, Quetiele index of weight, rate of smoking, finding rate of abnormal ECG and prevalence rate of cardiovascular disease (r = 0.79-0.99, P less than 0.01); and was negative correlation with the level of HDL-TC (r = -0.81, P less than 0.01).
