The aim of this study was to investigate the quality of life (HRQoL) in coronary artery disease(CAD) patients, admitted for rehabilitation within 3 months after an acute coronary event, in relation to treatment strategy [conservative treatment without revascularization (WR), percutaneous transluminal coronary angioplasty (PTCA), coronary artery bypass graft (CABG)]. Methods: Overall 719 consecutive CAD patients were involved in the study: WR (n=170), PTCA (n=226), CABG (n=323). HRQoL was estimated using the SF-36 questionnaire for total QoL and its two dimensions for physical and mental health [physical and mental component scores (PCS, MCS)]. Sexual dysfunction was assessed using the ASEX scale. Results: Significantly higher PCS, MCS and total SF-36, but lower ASEX score, were found in men compared with women. The ASEX score was significantly affected by age. Significantly higher PCS was found in PTCA group compared with that of CABG group. In multivariate analysis a significant positive association was obtained between PCS/MCS and male sex, between regular exercise, hyperlipoproteinemia, and permanent stress. ASEX was significantly positively associated with the age, CHF and non smoking. Conclusion: The results of this study have demonstrated significantly better HRQoL in men, younger CAD patients, patients who underwent PTCA and in patients without self-reported exposition to stress.
