Abstract
Primary percutaneous coronary intervention (PPCI) reduces cardiac mortality in acute ST elevation myocardial infarction (STEMI) and is currently the preferred treatment. Several studies have shown that manual aspiration of the thrombus during PPCI can prevent distal embolization, improve myocardial reperfusion and improve clinical outcome. The aim of our study was to determine the efficacy of thrombus extraction as adjunctive treatment before angioplasty for STEMI patients on mortality, recurrent myocardial infarction and the need for revascularization during hospitalization and the following 180 days, as well as to compare the different types of aspiration devices used during the study. Subjects and methods Two hundred and eleven patients were enrolled in the study with diagnosis of acute STEMI and planned for PPCI. PPCI with aspiration thrombectomy was done for 62 patients (aspiration group) and conventional PPCI (without aspiration thrombectomy) was done for 144 patients (control group). PPCI failed in five patients (2.3%). The aspiration group was subdivided into two subgroups according to the type of aspiration device used, Diver CE (32 patients) or Export (30 patients)
