Type A score (Jenkins Activity Survey) and risk of recurrent coronary heart disease in the aspirin myocardial infarction study.

The Jenkins Activity Survey (JAS), a questionnaire developed to assess the type A behavior pattern, was administered to 2,314 participants in the Aspirin Myocardial Infarction Study. All had a myocardial infarction (MI) before entering the study and were followed for at least 3 years. The JAS type A score was not significantly related to risk of recurrent major coronary events (definite nonfatal MI and coronary death) in the group of 244 women, the group of 2,070 men, or the subgroup of 671 men who were employed full-time in professional, technical or managerial positions. These results indicate that the JAS type A score is not useful in assessing prognosis after MI. By inference, traits measured by the JAS type A score, such as competitiveness, orientation toward achievement and preference for a rapid pace of life, appear not to be associated with increased risk of recurrent major coronary events.
