Impact of thrombus aspiration use and direct stenting on final myocardial blush score in patients presenting with ST-elevation myocardial infarction.
Many studies have reported that low final thrombolysis in myocardial infarction (TIMI) flow and/or myocardial blush grade (MBG) are independent predictors of mortality in patients with ST-elevation myocardial infarction (STEMI). In addition, distal coronary embolization is a major pitfall of conventional percutaneous coronary intervention (PCI) in such a context. ⋯ TA use before primary PCI for STEMI treatment resulted in improved final myocardial reperfusion. Of importance, TA use may have led to a better choice of the stent size and more frequent direct stenting. This benefit may directly improve patient outcomes.

Comparative StudyProphylactic use of intra-aortic balloon pump for high-risk percutaneous coronary intervention: will the Impella LP 2.5 device show superiority in a clinical randomized study?
This study aimed to report the in-hospital and 30-day event rates in patients undergoing non-emergent, high-risk percutaneous coronary intervention (PCI) and to evaluate whether the Impella Recover LP 2.5 device (Abiomed, Danvers, MA) demonstrates superiority over intra-aortic balloon pump (IABP) in the Protect II (A Prospective Feasibility Trial Investigating the Use of the Impella Recover LP 2.5 System in Patients Undergoing High Risk Percutaneous Coronary Intervention) study. ⋯ These data question the clinical benefit of the Protect II study, which is evaluating the relatively high-profile Impella LP 2.5 device over IABP for this high-risk population.

Predictors of myocardial contractile recovery after coronary revascularization in patients with prior myocardial infarction.
We sought to explore the prognostic power of certain patient characteristics to predict myocardial contractile recovery after coronary revascularization in patients with prior myocardial infarction. ⋯ In patients with prior myocardial infarction, the presence of Grade 2-3 collaterals to the infarct-related artery and the shorter age of infarction at the time of revascularization independently predicted myocardial contractile recovery after coronary revascularization.
