Randomized Controlled Trial Multicenter Study Comparative StudyImpact of diabetes mellitus on the safety and effectiveness of bivalirudin in patients with acute myocardial infarction undergoing primary angioplasty: analysis from the HORIZONS-AMI (Harmonizing Outcomes with RevasculariZatiON and Stents in Acute Myocardial Infarction) trial.
We sought to evaluate the safety and efficacy of bivalirudin compared with glycoprotein IIb/IIIa inhibitors (GPI) in diabetic patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). ⋯ In patients with diabetes mellitus presenting with STEMI undergoing primary PCI, anticoagulant therapy with bivalirudin compared with heparin plus GPI is safe and effective and might reduce cardiac mortality at 30 days and 1 year.

Multicenter Study Comparative StudyPrognostic significance of coronary thrombus in patients undergoing percutaneous coronary intervention for acute coronary syndromes: a subanalysis of the ACUITY (Acute Catheterization and Urgent Intervention Triage strategY) trial.
The objective of this study is to investigate the incidence and clinical implications of thrombus on baseline angiography among patients presenting with non-ST-segment elevation acute coronary syndromes (ACS) undergoing percutaneous coronary intervention (PCI). ⋯ Pre-procedural thrombus was present in 15% of moderate- and high-risk ACS patients undergoing PCI in the ACUITY trial. Baseline thrombus predicts increased ischemic complications at 30 days including a 3-fold increased risk of death as well as MI up to 1 year. Further evaluation of adjunctive pharmacotherapy is needed in this high-risk population.
