Abstract: | The objective of this study is to examine the role of a particular stress-enhancing psychosocial risk factor, termed overcommitment, in predicting restenosis after successful percutaneous transluminal coronary angioplasty (PTCA). Overcommitment defines
a personal pattern of coping with demands characterized by excessive striving in combination with a strong desire of being
approved and esteemed. One hundred six consecutive male patients with coronary artery disease who underwent PTCA were followed
over a mean of 12 months. The restenosis rate as defined by quantitative angiography was 34%. Multivariate analysis revealed
independent effects of high density lipoprotein cholesterol (odds ratio OR] 3.19), age (OR 3.43), and overcommitment (OR
2.86) on risk of restenosis. In conclusion, a stress-enhancing psychosocial person characteristic termed overcommitment acts
as an independent predictor of coronary restenosis after PTCA. As overcommitment is subject to cognitive-behavioral intervention,
results have implications for a more comprehensive approach to secondary prevention in cardiac patients.
