Abstract

Introduction:Although the routine use of manual thrombus aspiration (MTA) in patients with ST-elevation myocardial infarction (STEMI) provides no benefit compared to conventional primary percuta-neous coronary intervention (PCI), the use of this technique in the real world could be associated with theintracoronary thrombotic burden. The objective of this study is to evaluate whether the use of MTA isdirectly related to a high intracoronary thrombotic burden as defined by the Thrombolysis inMyocardial Infarction (TIMI) scale, in patients with STEMI.Methods:Descriptive retrospective study of patients with a diagnosis of STEMI, in whom the use of MTAwas assessed according to the coronary thrombus grading.Results:A total of 173 patients were included, with a mean age of 62 years, of whom 78% were male.Manual thrombus aspiration was performed in 52 (30%) of these patients, 98% (51/52) had a high throm-bus burden (TIMI thrombus burden grade > 4), compared to 39.6% (48/121) of the patients who did notundergo MTA. Thus, a high thrombus burden was significantly related to the use of MTA (p<0.0001).There were no ischemic stroke or deaths due to cardiovascular causes in the MTA group during hospital-ization
