Type A behavior pattern was strongly related to clinical coronary heart disease incidence, which occurred in 257 subjects over an average 8.5 years of follow-up, independent of other risk factors.
Cohort
Are risk factors, including type A behavior pattern, associated with the incidence of clinical coronary heart disease in middle-aged employed men?
Type A behavior pattern is strongly and independently associated with the incidence of clinical coronary heart disease in middle-aged employed men.
Clinical coronary heart disease (CHD) occurred in 257 subjects during eight to nine years of follow-up (average, 8 1/2 years) in a prospective study of 39- to 59-year-old employed men. Incidence of CHD was significantly associated with parental CHD history, reported diabetes, schooling, smoking habits, overt behavior pattern, blood pressure, and serum levels of cholesterol, triglyceride, and beta-lipoproteins. The type A behavior pattern was strongly related to the CHD incidence, and this association could not be explained by association of behavior pattern with any single predictive risk factor or with any combination of them.
Ray H. Rosenman (Mon,) conducted a cohort in Coronary Heart Disease. Type A behavior pattern was evaluated on Clinical coronary heart disease (CHD). Type A behavior pattern was strongly related to clinical coronary heart disease incidence, which occurred in 257 subjects over an average 8.5 years of follow-up, independent of other risk factors.
