Influence of manual thrombus aspiration on left ventricular diastolic function in patients with ST-segment elevation myocardial infarction treated with primary percutaneous coronary intervention.

Introduction: Data on effects of thrombus aspiration on left ventricular diastolic function in ST-elevation myocardial infarction (STEMI) population are scarce.

Objective: We sought to compare echocardiographic indices of the diastolic function and outcomes in STEMI patients treated with and without manual thrombus aspiration, in an academic, high-volume percutaneous coronary intervention (PCI) center.

Methods: A total of 433 consecutive patients who underwent primary PCI in 2011-2012 were enrolled in the study.
