ПОСТИНФАРКТНАЯ ЭЛЕКТРИЧЕСКАЯ НЕСТАБИЛЬНОСТЬ МИОКАРДА И ЖЕЛУДОЧКОВАЯ АРИТМИЯ У ПАЦИЕНТОВ С ПОКАЗАНИЯМИ К ПРОВЕДЕНИЮ ПЛАНОВОГО ЧРЕСКОЖНОГО КОРОНАРНОГО ВМЕШАТЕЛЬСТВА

Myocardial revascularization can significantly improve the long-term prognosis of patients with coronary artery disease. Currently, indications for these interventions in the most severe patients are gradually expanding. Percutaneous intervention in patients with coronary artery disease significantly reduces the risk of death from fatal ventricular arrhythmias (VA), progression of heart failure and AMI. However, despite the successful myocardial revascularization, a number of patients already develop life-threatening VA in the first year, and the symptoms of heart failure (HF) do not decrease or progress. Given its important prognostic role, primarily in patients after myocardial infarction, the aim of this work was to study the characteristics of heart rate turbulence, heart rate variability, QT interval dispersion, as well as indicators of the left ventricle remodeling in patients with ventricular arrhythmias after myocardial infarction and with indications for percutaneous coronary intervention
