Clinical-functional features in the course of a silent ischemic heart disease form depending on stenting

Abstract

Objective: to analyze the remote prediction of reperfusion therapy by stenting on the indicators of myocardial ischemia in patients with painless coronary heart disease (CHD) with postinfarction cardiosclerosis. Material and methods. The subject of the study was the study of 67 patients with painless myocardial ischemia (BIM), which occurred in people with postinfarction cardiosclerosis, among which 29 patients with BIM who had myocardial infarction (MI) with revascularization in the acute period by stenting (Group I) and 38 patients with BIM who had experienced the MI without a stenting (II group). Results. The absence of revascularization in the acute period of MI can negatively affect the state of myocardial perfusion and provoke ischemic heart muscle in patients with SMI. This is manifested by more intense manifestations of ischemic changes detected during Holter monitoring of electrocardiography (HM ECG). These studies allow SMI to be considered as a disease, which leads to a decrease in the electrical stability of the myocardium. It was established that for patients with SMI without stenting, characterized by higher average daily values of the number of ischemic episodes per day, the total daily duration of depression of the segment ST, the total amplitude of depression ST, the average duration of one ischemic episode compared with individuals after the conducted stenting (p<0,05). Conclusions. The absence of revascularization in the acute period of myocardial infarction can negatively affect the state of myocardial perfusion and predispose to ischemic heart muscle in patients with painless ischemia of the myocardium.
