Abstract
Western societies are now fraught with stresses that are new and unique to industrialized civilization. Epidemiologic surveys have shown that emotional interplay based on these new stresses has a dominant pathogenetic role in accelerating coronary atherosclerosis and the advent of clinical coronary heart disease. Coronary disease is far more likely to develop in a person with a personality characterized primarily by aggressiveness, competitiveness, and a sense of time urgency than in association with any other of the classic culprits of this disease.
