Heart and vascular diseases, or cardiovascular diseases (CVDs), have remained relevant for many decades and remain the most serious health problem in many countries around the world, including Kazakhstan. Experts from the World Health Organization (WHO) predict that by 2030 death from CVD may occur in 23.6 million people of working age. The widespread use of reconstructive and interventional methods, ensuring the restoration of blood flow in the myocardium, has made progress in the treatment of cardiovascular diseases. At the same time, serious problems remain during the reperfusion period at various stages of rehabilitation. The purpose of the review was to analyze the results of studies on the state of the myocardium in overweight individuals, especially after undergoing coronary artery surgery. The depth of the sample of literary sources was 20 years.

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
