Randomized Controlled TrialAdvanced age, antithrombotic strategy, and bleeding in non-ST-segment elevation acute coronary syndromes: results from the ACUITY (Acute Catheterization and Urgent Intervention Triage Strategy) trial.
This study sought to evaluate the impact of age on outcomes in patients with moderate- and high-risk non-ST-segment elevation acute coronary syndrome (NSTE-ACS) enrolled in the ACUITY (Acute Catheterization and Urgent Intervention Triage Strategy) trial. ⋯ Ischemic and bleeding complications after NSTE-ACS increase with age. Although ischemic event rates are not statistically different with either bivalirudin alone or a heparin plus glycoprotein IIb/IIIa inhibitor, bleeding complications are significantly less frequent with bivalirudin alone. Because of the substantial risk of bleeding in patients age > or =75 years, the number needed to treat to avoid 1 major bleeding event using bivalirudin alone was the lowest in the elderly group, especially among those undergoing PCI.

Randomized Controlled TrialPrevalence of low low-density lipoprotein cholesterol with elevated high sensitivity C-reactive protein in the U.S.: implications of the JUPITER (Justification for the Use of Statins in Primary Prevention: An Intervention Trial Evaluating Rosuvastatin) study.
We assessed the prevalence of low-density lipoprotein-cholesterol (LDL-C) <130 mg/dl with elevated high-sensitivity C-reactive protein (hsCRP) in the National Health And Nutrition Examination Survey (NHANES), weighted to be representative of the general U.S. population. ⋯ Extrapolating JUPITER eligibility to NHANES, an estimated 6.5 million additional adults could be potential candidates to initiate statin therapy.

Randomized Controlled Trial Clinical TrialA randomized assessment of the incremental role of ablation of complex fractionated atrial electrograms after antral pulmonary vein isolation for long-lasting persistent atrial fibrillation.
This study sought to determine whether ablation of complex fractionated atrial electrograms (CFAEs) after antral pulmonary vein isolation (APVI) further improves the clinical outcome of APVI in patients with long-lasting persistent atrial fibrillation (AF). ⋯ Up to 2 h of additional ablation of CFAEs after APVI does not appear to improve clinical outcomes in patients with long-lasting persistent AF.

Randomized Controlled Trial Multicenter StudyEffect of intravenous FX06 as an adjunct to primary percutaneous coronary intervention for acute ST-segment elevation myocardial infarction results of the F.I.R.E. (Efficacy of FX06 in the Prevention of Myocardial Reperfusion Injury) trial.
The purpose of this study was to investigate whether FX06 would limit infarct size when given as an adjunct to percutaneous coronary intervention. ⋯ In this proof-of-concept trial, FX06 reduced the necrotic core zone as one measure of infarct size on magnetic resonance imaging, while total late enhancement was not significantly different between groups. The drug appears safe and well tolerated. (Efficacy of FX06 in the Prevention of Myocardial Reperfusion Injury [F.I.R.E.]; NCT00326976).

Randomized Controlled Trial Multicenter Study Clinical TrialBosentan for treatment of inoperable chronic thromboembolic pulmonary hypertension: BENEFiT (Bosentan Effects in iNopErable Forms of chronIc Thromboembolic pulmonary hypertension), a randomized, placebo-controlled trial.
Our goal was to investigate the effect of treatment with the oral dual endothelin receptor antagonist bosentan on the hemodynamics and exercise capacity of patients with chronic thromboembolic pulmonary hypertension (CTEPH). ⋯ This study demonstrated a positive TE of bosentan on hemodynamics in this patient population. No improvement was observed in exercise capacity. Further trials are needed to define the role of medical therapy in patients with CTEPH (Bosentan Effects in Inoperable Forms of Chronic Thromboembolic Pulmonary Hypertension; NCT00313222).
