[Personality and restenosis after percutaneous transluminal coronary angioplasty]

The paper is an attempt to find out which personality traits predispose to increased risk of restenosis in patients after first percutaneous transluminal coronary angioplasty (PTCA). The Eysenck Personality Questionnaire-Revised (EPQ-R) was used in 87 consecutive men (31 persons with university education, 26 secondary, and 20 occupational education; mean age 50 years, range from 32 to 72) on the second day after PTCA. Raw data were used in statistical analysis of EPQ-R. Restenosis was identified in coronary angiography within several weeks to 6 months after PTCA. Restenosis was detected in 25 patients. Groups with and without restenosis were compared with respect to EPQ-R parameters referring to neurotism (14.8 +/- 3.26 vs. 12.4 +/- 5.63; p < 0.01), extroversion (13.7 +/- 3.82 vs. 13.7 +/- 3.95; NS) and psychotism (5.7 +/- 3.20 vs. 7.2 +/- 4.8; p = 0.08). There was positive correlation between the level of neurotism and the frequency of restenosis (logistic regression coefficient = 0.225; OR = 1.252; p = 0.03), but not with age and the level of education. In contrast, psychotism did not correlate significantly with frequency of restenosis. In conclusion, neurotism appears to affect the frequency of restenosis, which means that emotional imbalance through reducing immunity to stress and skills of effective coping with it increases the risk of restenosis. Psychological intervention directed at developing the skills of coping with stress should be a part of the therapy in patients after PTCA.
