Background: Although the clinical benefits of coronary interventions seem to be confirmed, their effects on quality of life (QoL) are still scarcely studied.
Objective: To assess the QoL in multivessel coronary disease in patients randomly undergoing surgery, angioplasty or medical treatment.
Methods: The Short-Form Health Survey (SF-36) questionnaire was answered by 483 patients. Of these, 161 underwent surgical revascularization, 166 underwent angioplasty, and 153 were medically treated.
Results: At baseline, 86% of the patients referred angina, 34% referred infarction, and 32% were smokers. Medical Treatment: 12 patients (7.7%) had AMI, 24 (15.3%) underwent surgery, and 19 (12.1%) died. In addition, 5 (3.2%) had stroke, and 40 (25.6%) had angina. As regards the mental component, 64.1% and 30.8% had their condition improved and worsened, respectively. As regards the physical component, 70.5% and 27.6% had their condition improved and worsened, respectively.
Surgery: 13 patients (8.1%) had AMI, 2 (1.2%) underwent surgery, and 12(7.4%) died. Also, 9 (5.6%) had stroke and 30 (18.6%) had angina. As regards the mental component, 72.7 % and 25.5% had their condition improved and worsened, respectively. As regards the physical component, 82.6% and 16.1% had their condition improved and worsened, respectively. Angioplasty: 18 patients (10.9%) had AMI, 51 (30.7%) underwent interventions, and 18 (19.9%) died. Additionally, six (3.6%) presented stroke and 35 (21%) reported angina. As regards the mental component, 66.9% and 26.5% had their condition improved and worsened, respectively. As regards the physical component, 77.1% and 20.5% had their condition improved and worsened, respectively.
Conclusion: Improvement was observed in all domains and in the three therapeutic modalities. Comparatively, surgery had provided a better quality of life after a four-year follow-up.
