TYPE-A BEHAVIOR AND ANGIOGRAPHIC FINDINGS

This study examines the association between Type A personality and the extent of coronary artery disease found at angiography. Our initial work failed to demonstrate an association between Type A as measured by the Jenkins Activity Survey (JAS) and vessel disease. In this study on a second cohort of 105 patients, we have used both the JAS and semi-structured interview as measures for Type A personality. All patients were assessed prior to angiography. Coronary arteries were judged significantly narrowed if angiography revealed >50% narrowing of the vessels' diameter. Neither the JAS nor the semi-structured interview were significantly associated with the extent of vessel disease. The discrepancy between our findings and those of other investigators may be attributable to population differences. © 1979.
