Search for: [Abstract = "Introduction\: Mechanical reperfusion significantly improves the results oftreatment in patients with acute ST\-segment elevation myocardialinfarction\(STEMI\). Its effectiveness is limited by the occurrence ofmicrovascular damage, known as impaired reperfusion \(no\-reflowphenomenon\).Objective\: To find factors independently associated with the occurrence ofimpaired reperfusion, and to determine the prognostic value of the no\-reflowphenomenon for left ventricula\(LV\) remodeling and function recovery inpatients with STEMI treated with primary percutaneous coronaryintervention\(PCI\).Methods\: Data of 108 patients with STEMI were studied. Myocardial perfusionwas assessed using angiography and ecg. The enzymatic injury was evaluatedaccording to CK,CK\-MB, TnI level. The LV function and remodeling wasexamined by echocardiography and magnetic resonance imaging\(MRI\) atbaseline and then after 4 months. The microvascular obstruction \(MVO\) areawas measured by MRIResults\: The multivariate analysis showed that left anterior descending arterywas independently associated with the lack of restoration of full epicardialflow\(TIMI<3\) or incomplete tissue reperfusion \(TMPG\-0\/1\) after PCI \(p=0,049p=0,035\). The strongest determinant of MVO was infarct size \(p<0,0001\). TheLV remodeling expressed as a 20% increase of the end\-diastolic volume index\(EDVI\) within 4 m. after STEMI was determined by baseline EDVI \("]
