Randomized Controlled Trial Comparative StudyA randomized trial to evaluate the relative protection against post-percutaneous coronary intervention microvascular dysfunction, ischemia, and inflammation among antiplatelet and antithrombotic agents: the PROTECT-TIMI-30 trial.
The goal of this study was to evaluate glycoprotein IIb/IIIa inhibition with eptifibatide when administered with indirect thrombin inhibition as compared with monotherapy with direct thrombin inhibition with bivalirudin among patients with non-ST-segment elevation acute coronary syndromes (ACS). ⋯ Among moderate- to high-risk patients with ACS undergoing PCI, coronary flow reserve was greater with bivalirudin than eptifibatide. Eptifibatide improved myocardial perfusion and reduced the duration of post-PCI ischemia but was associated with higher minor bleeding and transfusion rates. Ischemic events and biomarkers for myonecrosis, inflammation, and thrombin generation did not differ between agents.

Randomized Controlled TrialRandomized controlled trial of the effects of remote ischemic preconditioning on children undergoing cardiac surgery: first clinical application in humans.
We conducted a randomized controlled trial of the effects of remote ischemic preconditioning (RIPC) in children undergoing repair of congenital heart defects. ⋯ This study demonstrates the myocardial protective effects of RIPC using a simple noninvasive technique of four 5-min cycles of lower limb ischemia and reperfusion. These novel data support the need for a larger study of RIPC in patients undergoing cardiac surgery.

Effect of door-to-balloon time on mortality in patients with ST-segment elevation myocardial infarction.
We sought to determine the effect of door-to-balloon time on mortality for patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). ⋯ Time to primary PCI is strongly associated with mortality risk and is important regardless of time from symptom onset to presentation and regardless of baseline risk of mortality. Efforts to shorten door-to-balloon time should apply to all patients.
