title: Components of type A behavior and two-year prognosis of patients with acute coronary syndrome.
abstract: We investigated prospectively the relationship of Type A behavior and its subcomponents with cardiac mortality and recurrent nonfatal cardiac events in a 2-yr. follow-up of 90 patients [69 men and 21 women, M age=56.4 yr., SD=8.4] after acute coronary syndrome. Type A behavior was assessed via the general Bortner Type A Index. Each patient completed the Bortner's scale before hospital discharge. During the first 2-yr. follow-up, there were 14 cardiac deaths among patients with myocardial infarction. 8 patients had recurrent cardiac events and were hospitalized, and 19 patients had an effort-induced angina pectoris. Patients with acute myocardial infarction who died during follow-up had a significantly lower Bortner score than patients with a secondary cardiac event. Bortner scores of patients with acute myocardial infarction who died indicated Type B behavioral patterns. Mortality was significantly higher in the patients classified as showing Type B (21.8%) behavior than in the patients classified as showing Type A (12.0%) behavior. Patients with a secondary cardiac event had more common Type A behavior patterns and higher Bortner scores than patients without a secondary cardiac event. The items on Bortner's scale "very competitive, ever rushed, tries to do too many things at once, fast in daily activities and expresses feelings" were inversely associated with cardiac deaths. These findings suggest that patients with acute coronary syndrome classified by scores on the Bortner scale as Type B behavior have a greater probability of death, and patients classified on the Bortner scale as Type A behavior have a greater probability of secondary cardiac events during follow-up. This finding may have implications for the treatment of patients with acute coronary syndrome. The inferior survival of patients with Type B personalities argues against attempts to modify Type A behavior in postinfarction patients.
