Peculiarities of Diabetes Mellitus Impact on the Effectiveness of Cardiac Rehabilitation of Patients with Coronary Heart Disease After Myocardial Revascularization

Abstract

Aim: To investigate the impact of diabetes mellitus on the course of the disease, the quality of rehabilitation measures and the psycho-emotional state of patients. Materials and Methods: The study involved 134 patients, who were divided into four groups depending on the method of revascularization and the presence or absence of diabetes mellitus. The patients underwent a 21-day rehabilitation programme, at the beginning and at the end of which they were assessed for left ventricular ejection fraction, exercise tolerance, maximum oxygen consumption, and treatment adherence. Throughout the study, the patients were under the supervision of a psychologist. Results: The study found that patients with diabetes showed a significant improvement in the measured indicators, but to a lesser extent than patients without diabetes. Conclusions: The mechanisms of poorer outcomes in patients with diabetes are mostly related to psycho-emotional factors as a result of the diagnosed disease, but they require further study.
