A review of research examining the coronary-prone behavior pattern

With the increasing incidence of coronary heart disease (CHD) and the subsequent interest in factors which contribute to its development, the idea of a coronary-prone (Type A) behavior pattern has attracted much attention in recent years. In this paper, research on the coronary-prone behavior pattern is reviewed. Type A behavior is found to be fairly accurate in predicting the likelihood and severity of CHD, at least in large groups of people. Problems in measuring and in more clearly defining the components of Type A behavior are discussed. Future investigations are urged, focusing on how the behavior pattern develops and on strategies for intervention.
