Abstract
Thrombus exerts a major impact on the performance and outcome of primary and rescue interventions in acute ST-elevation myocardial infarction. Although the optimal treatment of thrombotic lesions is still controversial, thrombus aspiration provides an effective method to achieve successful reperfusion during primary angioplasty. We compared clinical and angiographic outcomes in 286 patients with acute ST-elevation myocardial infarction undergoing primary percutaneous transluminal coronary angioplasty (PTCA) and thrombus aspiration with those who underwent conventional PTCA without thrombus aspiration. Thrombus aspiration during primary percutaneous coronary intervention in patients with high thrombus burden resulted in better Thrombolysis in Myocardial Infarction (TIMI) 3 flow in the infarct-related artery and helped achieve faster ST-segment resolution on the electrocardiogram compared with conventional angioplasty without thrombus aspiration.
