Background
Primary percutaneous coronary intervention (PPCI) is the most effective and validated treatment strategy of ST segment elevation myocardial infarction (STEMI). Nevertheless, normal myocardial perfusion cannot always be achieved at the end of the procedure in a significant number of patients with STEMI. The aim of this study was to investigate angiographic and procedural predictors of angiographically visible distal embolization (AVDE) during PPCI and the assessment of mid and long term mortality.
Methods
461 consecutive patients undergoing PPCI for acute STEMI and matching eligibility criteria of the study between January 2010 and December 2011 were included in the study. Patients were divided into two groups; 61 (13.1%) with AVDE and 404 patients without AVDE based on angiograms performed during PPCI.
