Follow-up Study of Life Quality Parameters in Patients with Ischemic Heart Disease after Myocardial Revascularization

Topicality: Myocardial revascularization in patients with stable ischemic heart disease (IHD) can improve the quality of life (QOL).
Objective: The aim was to establish long-term influence of revascularization methods on QOL in IHD patients.
Materials and methods: 174 patients with stable IHD, average age 62±0.7 years, were studied. There were 136 males (78.2%) and 38 females (21.8%). The patients were divided into two groups: group I included 86 patients (49.4%) who had undergone coronary artery stenting, and group II consisted of 88 patients (50.6%) after CABG. QOL parameters were evaluated in 12 months after revascularization by health survey questionnaire MOS SF36.
Results: All IHD patients had decreased life quality indices: physical functioning (PF) – 54.8 scores, role limitations due to physical problems (RP) –17.8, bodily pain (BP) – 57, social functioning (SF) – 68.7, general mental health (GMH) – 58.9, role limitations due to emotional problems (RЕ) – 58.3, vitality (VT) – 37.7, general health perceptions (GHP) – 34.2, physical health (PH) – 43.1, mental health(MH)– 35.9, general health(GH) – 62.2 scores.There were no significant differences between the indices analyzed by revascularization method. Concomitant pathology was found to influence QOL. The following decreased parameters were observed: PF(р<0.001), RЕ(р<0.02), BP, SА, GMH (р<0.05), VT, GHP (р<0.001), PH, MH, GH (p<0.001) – in chronic obstructive respiratory diseases; RE – in diabetes mellitus (p<0.02); BP and GHP – in gastrointestinal tract diseases (p<0.05).
Conclusions: No significant differences in QOL indices were found in IHD patients who had undergone myocardial revascularization, depending on the choice of revascularization method. The presence of associated pathology was found to have great influence on QOL.
