Influence of Percutaneous Coronary Intervention on Heart Failure in Patients with Q-Wave, Qs-Wave Myocardial Infarction

In patients with myocardial infarction without revascularization chronic heart failure is characterized by burdened course of disease manifesting in deterioration of clinical condition, decrease in exercise tolerance, significant changes in hemodynamics, intense manifestations of myocardial ischaemia, significant left ventricular remodeling compared to those individuals who underwent endovascular myocardial reperfusion by culprit coronary artery stenting. Percutaneous coronary intervention was found to promote significant increase in left ventricular ejection fraction, a significant decrease in end-systolic volume, myocardial mass and left ventricle myocardial performance index compared to patients without revascularization. Reperfusion therapy improves the course of post-infarction period and therefore should be a priority treatment of patients with acute myocardial infarction.?
