Myocardial condition in overweight patients at different stages of rehabilitation after revascularization

Abstract

The aim of the study was to study the dynamics of myocardial function indicators in overweight patients at different stages of rehabilitation after coronary revascularization. Material and methods. This article presents the interim results of prospective study which was conducted at the Tulpar cardiorehabilitation center (Karaganda, Kazakhstan). The study included 135 patients after restoration of blood flow in the coronary arteries (coronary artery bypass grafting, stenting). The average age was 58 ± 6 years. Exclusion criteria: acute myocardial infarction; chronic heart failure, functional class III–IV; acute disorders of cerebral circulation; diabetes mellitus in a state of decompensation; obesity I–III degree. We observed patients in dynamics at three stages of rehabilitation. 41 patients were included in the study at the first stage, 43 – at the second stage and 51 – at the third stage. Patients were included from different stages of rehabilitation. The groups were comparable in terms of the parameters of the structural and functional state of the myocardium, the same age range. Results. Considering the size of the interventricular septum, the posterior wall of the left ventricle, the relative thickness of the myocardium and the myocardial mass index, it can be noted that statistically significant hypertrophy of the left ventricle was observed in all observation periods (p < 0.05). Conclusions. In overweight patients who underwent myocardial revascularization surgery, persistent changes in the myocardium remain at the 3rd stage of rehabilitation
