Key result
Type A behavior shows no link to CAD extent while self-references correlate with previous MI.
Why the study?
Does Type A behavior or self-involvement correlate with the extent of coronary atherosclerosis in men undergoing coronary angiography?
Cross-Sectional (n=150)
Does Type A behavior or self-involvement correlate with the extent of coronary atherosclerosis in men undergoing coronary angiography?
Answers are grounded in this paper and cite their sources.
Self-involvement, as measured by self-references in speech, is significantly correlated with the extent of coronary artery disease, whereas Type A behavior is not.
Prior to coronary angiography, 150 men were assessed for Type A behavior using the structured interview and two questionnaire measures. The results show no relationship between Type A behavior and extent of coronary artery disease (CAD). A second finding is that the number of self-references (I, me, my) derived from speech in the structured interview correlated positively with the number of previous myocardial infarctions and the extent of CAD; self-references correlated negatively with time on the treadmill and catheterization ejection fraction. Multiple regression analyses show self-references to remain a significant correlate of extent of disease when controlled for age, blood pressure, cholesterol, and Type A behavior.

Scherwitz et al. (1983) conducted a cross-sectional in Coronary artery disease (n=150). Type A behavior and self-references was evaluated on Extent of coronary artery disease. Type A behavior showed no relationship with coronary artery disease extent, while self-references correlated positively with previous myocardial infarctions and CAD extent.
