Abstract
The present study tested the hypothesis that Type A subjects respond with greater cardiovascular response than Type B subjects during the structured interview used to assess the Type A pattern. Coronary patients (n = 31) and patient controls (n = 33) were subjected to the interview and a history quiz while ECG and blood pressure were monitored. As predicted. Type A relative to Type B subjects evidenced significantly greater increases in both systolic and diastolic blood pressure, which were sustained over the course of the entire 12-15 minute interview. Type A subjects compared with B's also showed significantly greater blood pressure elevations during the quiz. Coronary patients displayed significantly greater Type A attributes than control subjects and tended to show greater blood pressure elevations than controls during the interview. In addition, the quiz induced significant elevations in the blood pressure of coronary patients, but not patient controls, over that displayed during the interview, despite the presence of beta-adrenergic blocking medication. Implications of the findings for coronary-prone behavior and coronary heart disease are discussed.
