This study investigates the relationships between the coronary-prone Type A behavior pattern, coronary heart disease CHD, and stress. Behavioral and organizational data were obtained from 204 respondents physiological data were obtained from 184 respondents. The physiological data consisted of cholesterol, HDL cholesterol, and cortisol 116 out of 184. cholesterol, HDL cholesterol, and the ratio of cholesterol divided by HDL ratio were used as indicators of CHD. Cortisol was used as an indicator of felt stress. Factor analysis, Pearson product-moment correlation analysis, and multiple regression analysis were employed. The results indicate that a high-fat diet produces higher levels of cholesterol. Smokers have higher cholesterol levels than non-smokers. Exercise increases the HDL cholesterol level, especially in Type A subjects. Social support and smoking do not significantly affect felt stress cortisol.
