THE VALUE OF HOLTER MONITORING AND THE LEVEL OF SYSTEMIC INFLAMMATION IN PATIENTS WITH STABLE ISCHEMIC HEART DISEASE COMBINED WITH TYPE 2 DIABETES, DEPENDING ON THE NUMBER OF AFFECTED CORONARY ARTERIES

Abstract

Diabetes mellitus (DM) is one of the significant medical and social problems of modern society, which is due to high morbidity and prevalence, frequent occurrence of chronic micro- and macrovascular complications. Coronary heart disease (CHD) in patients with type 2 diabetes is 2-4 times more common than in people of the same age without diabetes [1]. In the absence of apparent signs of atherosclerosis, the risk of developing coronary artery disease in the next 10 years is 30% [2]. To date, the course and prognosis of this group of patients have not been sufficiently studied, objective clinical and diagnostic criteria for the development of complications of myocardial infarction have not been developed, and the problem of choosing pathogenetically based methods of treatment of CHD in combination with type 2 diabetes remains unresolved [3].The aim of the work was to investigate the informativeness of Holter monitoring (HM), the correlation of HM indicators, C-reactive protein (CRP) and carbohydrate metabolism in patients with stable coronary heart disease (CHD) in combination with type 2 diabetes for the prognosis of the course of this pathology, timely individual treatment and prevention occurrence of endpoints.Material and methods. The study involved 95 patients with coronary heart disease with angina pectoris functional class (FC) III and heart failure (HF FC III with a preserved left ventricular ejection fraction (LVEF); of them, 60 patients had concomitant type 2 DM in the compensation stage.Results. In patients with comorbidity (a combination CHD and type 2 diabetes), episodes of ST depression/elevation, tachycardia, and extrasystoles were more often registered in patients with multivessel lesions of CA (р<0.05), according to HM; the content of CRP in blood serum increased in proportion to the severity of the course of the disease, which depended on the number of affected CA.Conclusions. The nature and severity of the course of CHD correlate with comorbid pathology and the number of CAs affected by atherosclerosis. In the case of multivessel damage, according to the data of clinical, functional and laboratory research, an aggressive progression of cardiac pathology was noted.
