Dynamics of Cardiomarkers at Different Weight Levels of Acute Myocardial Infarction in Omorbidity

Abstract

The differentiation of viable (stenning, hibernation) and nonviable myocardium (necrosis) in the infarction zone in patients with left ventricular dysfunction is very important for early stratification of the risk of developing chronic heart failure. In modern cardiology, a number of non-invasive methods are used to identify the viability of the myocardium, but not all are accessible and harmless. The aim of the review was to summarize the data on the viability of the myocardium, to analyze the literature on non-invasive imaging techniques in identifying viability and to identify those that are of the greatest clinical significance in patients with myocardial infarction with ischemic left ventricular dysfunction. It is concluded that to date there are radionuclide and echocardiographic methods for diagnosing a viable myocardium. Stress echocardiography is preferable for the diagnosis of viable myocardium in myocardial infarction due to lower cost, safety, wide availability, and most importantly, the absence of ionizing radiation.
