Randomized Controlled Trial Multicenter Study Comparative StudyUse of a nurse-led intervention to optimize beta-blockade for reducing cardiac events after major noncardiac surgery.
Although guidelines recommend the use of beta-adrenoceptor blocking drugs to reduce cardiac events (CEs) after major noncardiac surgery, trial results have varied between showing benefit, ineffectiveness, and harm. We sought whether optimizing beta-blockade (BB) delivery could make them more effective. ⋯ These data confirm a persistent CE rate after major noncardiac surgery despite nurse-led dose titration of bisoprolol. Cardiac events were equivalent to a UC strategy based on DbE results.

Randomized Controlled Trial Comparative StudyImpact of female gender and transradial coronary stenting with maximal antiplatelet therapy on bleeding and ischemic outcomes.
Female gender has been associated with poorer outcomes after percutaneous coronary intervention (PCI) and femoral approach. However, no data are available on the impact of gender and transradial PCI with maximal antiplatelet therapy on bleeding and ischemic outcomes. ⋯ Despite more comorbidities, female gender was not a predictor of adverse clinical outcomes after transradial PCI with maximal antiplatelet therapy. Still, female gender remained associated with a higher risk of local hematomas. Efforts should continue to identify modifiable factors to reduce procedural bleeding in women, regardless of the access site.

Randomized Controlled Trial Comparative StudyThrombolysis in Myocardial Infarction (TIMI) Risk Index predicts long-term mortality and heart failure in patients with ST-elevation myocardial infarction in the TIMI 2 clinical trial.
TIMI (Thrombolysis in Myocardial Infarction) Risk Index (TRI) is a simple bedside score that predicts 30-day mortality in patients with ST-elevation myocardial infarction (MI). We sought to evaluate whether TRI was predictive of long-term mortality and clinical events. ⋯ The simple TRI can predict increased long-term mortality, CHF, and composite death/CHF.

Comparative StudyImplantable cardioverter-defibrillator deactivation at the end of life: a physician survey.
Among older adults, implantable cardioverter-defibrillator (ICD) use is increasing. ICD shocks can occur at end of life (EOL) and cause substantial distress, warranting consideration of ICD deactivation discussions. This nationwide physician survey sought to (1) determine if physicians discuss ICD deactivation at the EOL, (2) identify predictors of those discussions, and (3) ascertain physicians' knowledge/attitudes about ICD use. ⋯ Most physicians would discuss ICD deactivation at EOL. The strongest predictor of this was a history of prior discussions. Knowledge about ICDs varies by specialty, and most expressed a desire for more expert guidance about ICD management at EOL.

Randomized Controlled Trial Multicenter Study Comparative StudyRationale and design of a randomized, double-blind, placebo-controlled trial of 6 versus 12 months clopidogrel therapy after implantation of a drug-eluting stent: The Intracoronary Stenting and Antithrombotic Regimen: Safety And EFficacy of 6 Months Dual Antiplatelet Therapy After Drug-Eluting Stenting (ISAR-SAFE) study.
Concern regarding the rate of delayed acute stent thrombosis associated with drug-eluting stent (DES) treatment has resulted in upward revision of the advised duration of dual antiplatelet therapy after DES implantation by both European and United States guideline writing committees. In fact, the corroboration of an increased rate of late thrombotic events remains outstanding, and these clinical practice guidelines are limited by an inadequate evidence base on which to ground their recommendations. ⋯ There is clinical equipoise on the issue of optimal duration of dual antiplatelet treatment after percutaneous intervention with DES. The ISAR-SAFE trial aims to assess whether discontinuation of clopidogrel 6 months after DES implantation is noninferior to routine prolongation of such therapy out to 1 year.
