Safety of coronary angiography and percutaneous coronary intervention via the radial versus femoral route in patients on uninterrupted oral anticoagulation with warfarin.
To evaluate access site and other bleeding complications associated with radial versus femoral access in patients receiving oral anticoagulation (OAC) with warfarin. ⋯ We retrospectively identified 255 consecutive patients on warfarin who underwent coronary angiography, 97 of whom underwent a percutaneous coronary intervention. The data reveal a reduction in Bleeding Academic Research Consortium bleeds (1.6% vs 8.1%, P = .02) with radial versus femoral access. The radial approach was associated with an overall lower rate of any vascular or bleeding complication than the femoral approach during percutaneous coronary intervention (1% vs 23%, P = .001).

Randomized Controlled Trial Multicenter Study Comparative StudyRandomized comparison of biodegradable polymer sirolimus-eluting stents versus durable polymer everolimus-eluting stents for percutaneous coronary revascularization: rationale and design of the BIOSCIENCE trial.
Biodegradable polymers for release of antiproliferative drugs from metallic drug-eluting stents aim to improve long-term vascular healing and efficacy. We designed a large scale clinical trial to compare a novel thin strut, cobalt-chromium drug-eluting stent with silicon carbide-coating releasing sirolimus from a biodegradable polymer (O-SES, Orsiro; Biotronik, Bülach, Switzerland) with the durable polymer-based Xience Prime/Xpedition everolimus-eluting stent (EES) (Xience Prime/Xpedition stent, Abbott Vascular, IL) in an all-comers patient population. ⋯ The BIOSCIENCE trial will determine whether the biodegradable polymer SES is noninferior to the durable polymer EES with respect to TLF.

Randomized Controlled Trial Comparative StudyEfficacy and safety of apixaban compared with warfarin for stroke prevention in patients with atrial fibrillation from East Asia: a subanalysis of the Apixaban for Reduction in Stroke and Other Thromboembolic Events in Atrial Fibrillation (ARISTOTLE) Trial.
The perceived risk of serious bleeding is an obstacle to the use of oral anticoagulation in East Asia. The efficacy and safety of apixaban in East Asian patients with atrial fibrillation are unknown. ⋯ Apixaban resulted in similar reductions in stroke or systemic embolism and major bleeding and greater reductions in major or clinically relevant nonmajor bleeding in patients from East Asia. Warfarin is associated with more intracranial bleeding, particularly in patients from East Asia.

Observational StudyTemporal trends in the use of intraaortic balloon pump associated with percutaneous coronary intervention in the United States, 1998-2008.
With conflicting evidence regarding the usefulness of intraaortic balloon pump (IABP), reports of IABP use in the United States have been inconsistent. Our objective was to examine trends in IABP usage in percutaneous coronary intervention (PCI) in the United States and to evaluate the association of IABP use with mortality. ⋯ The utilization of IABP associated with PCI significantly decreased between 1998 and 2008 in the United States, even among patients with acute myocardial infarction and shock.
