Routine aspiration thrombectomy is associated with increased stroke rates during primary percutaneous coronary intervention for myocardial infarction.

Our data series of STEMI patients, suggest that routine thrombus aspiration during primary PCI is associated with a significantly higher stroke, rate however, thrombus aspiration reduced mortality rate. This is consistent with current guidelines which don't recommend the routine use of thrombus aspiration for primary PCI. A possible mortality reduction in patients with high thrombus grades was seen which may warrant further study.
