Prevention of Complications in Patients With Myocardial Infarction and Concomitant Metabolic Syndrome

Abstract

In Ukraine, coronary heart disease is still occupying the first place in the structure of the causes of death and primary disability (22.8%), and the incidence of myocardial infarction among people of working age is 48.9 per 100 thousand. The aim of this study was to increase the effectiveness of the treatment and prevention of complications in patients with acute coronary syndrome (myocardial infarction) and concomitant metabolic syndrome by including L-carnitine and L-arginine to the integrated therapy. The study involved 71 patients with acute coronary syndrome (ACS) with ST-segment elevation and concomitant metabolic syndrome. Among the 37 individuals who were prescribed a course of cytoprotective therapy additional to the standard drug therapy according to the protocol of the Ministry of Health, formed a test group. The control group consisted of 34 patients who only received standard protocol treatment with corticosteroids (MI). The diagnosis of acute myocardial infarction was verified according to the ESC recommendations (2017). Diagnosis of metabolic syndrome (MS) was established based on the recommendations of the International Diabetes Federation (IDF, 2016). It was found that due to the integrated therapy including L-arginine and L-carnitine, the patients with ACS (MI) and concomitant MS achieved a significant improvement in central cardiohemodynamics and the restoration of vascular endothelial function that was often accompanied by the following complications of corticosteroids (MI) as reperfusion arrhythmias and blockades and acute heart (left ventricular) failure. The patients with acute myocardial infarction and concomitant MS demonstrated pronounced deterioration of morpho-functional parameters of the heart, and namely the development of its post infarction remodelling with subsequent impairments of systolic and diastolic heart function and the development of heart failure and endothelial vascular dysfunction. A mixture of L-arginine and L-carnitine added to the standard therapy significantly reduces the incidence and severity of complications of acute MI such as reperfusion arrhythmias and acute left ventricular failure.
