OBJECTIVE: In this study, we compared the impact of two main strategies of intervention against multivessel coronary disease (MVD), complete revascularization (CR) and incomplete revascularization (IR), on patients’ quality of life.

PATIENTS AND METHODS: 210 patients with multivessel disease were selected for this study. The diagnosis was confirmed by coronary angiography, and patients were divided in two different groups according to the type of revascularization method they received: (1) the complete revascularization (CR) group and (2) the incomplete revascularization (IR) group. Patients were asked to fill out SF-36 life quality questionnaire in three-time points: (1) before the operation; (2) one month after the operation; and (3) one year after the operation.

RESULTS: Baseline conditions showed no significant intergroup differences. Scores obtained from different sections in the questionnaire were compared between two groups and results revealed that scores in every section were significantly different (p < 0.05) except for the general health condition section. Patients in the CR group scored higher in physical functioning, physical role, body pain, vitality, social role, emotional role and mental health. Scores obtained from different time points also varied significantly (p < 0.05), with those of one month and one year after operation being noticeably higher than the preoperative ones.

CONCLUSIONS: Both complete and incomplete revascularization methods can effectively improve the short- and long-term quality of life in patients with multivessel coronary artery disease. However, complete revascularization can produce better results.
