A Simple Index To Predict Myocardial Infarction Size In Patients With Acute STEMI Undergoing Primary PCI. Correlation With Myocardial Perfusion Imaging.

Abstract

Primary percutaneous intervention (PCI) is now classified as class I indication in STEMI in the Guidelines of the European Society of Cardiology (ESC). Reperfusion therapy is the cornerstone of the treatment of patients with acute ST elevation myocardial infarction (STEMI). Despite early revascularization in acute myocardial infarction (MI), substantial damage of myocardium in the area supplied by the occluded artery cannot be avoided in some patients. According to references, 25–33% of patients develop significant left ventricle (LV) remodeling and 11.5–22% develop major adverse cardiac events . In long-term follow-up The final size of infarction is also directly connected to the risk of complications such as life-threatening arrhythmias or hospitalization because of heart failure . The aim of this study is to assess the value of culprit vessel diameter using the simple index provided
