Clinical Benefit of Warfarin in Dialysis Patients With Atrial Fibrillation
Patients with atrial fibrillation (AF) and end-stage chronic kidney disease (CKD) receiving dialysis are at higher risk of stroke (1). Warfarin has been shown to reduce the frequency of strokes by 64.0% in patients with AF; however, its use in dialysis patients has not received consensus owing to the lack of randomized controlled trial data and associated increased bleeding risk.

Duration of Triple Therapy in Patients Requiring Oral Anticoagulation After Drug-Eluting Stent Implantation
We read with much interest the paper and editorial by Fiedler et al. (1) and Bhatt et al. (2) regarding the optimal duration of dual antiplatelet therapy (DAPT) in patients on systemic anticoagulation in a recent issue of the Journal. In this randomized, open-label trial, 614 patients underwent drug-eluting stent (DES) implantation and were randomized to either 6 weeks or 6 months of clopidogrel therapy. They found no difference in the primary endpoint (composite of death, myocardial infarction, definite stent thrombosis, stroke, or TIMI [Thrombolysis In Myocardial Infarction] major bleeding) between the 2 groups (9.8...

The Challenge of Getting it Just Right Optimizing Long-Term Antithrombotic Therapy After Acute Coronary Syndrome ∗
Acute coronary syndrome (ACS) is associated with substantial morbidity and mortality (1,2). Initial treatment in the hospital consists of intensive antithrombotic therapy combining parenteral anticoagulation with antiplatelet therapy, whereas secondary prevention relies primarily on dual antiplatelet therapy (DAPT), most commonly aspirin and clopidogrel. However, patients with ACS remain at significant risk of recurrent adverse cardiovascular events (3). Mitigation of this risk requires a delicate balance between escalation of antithrombotic therapy to reduce ischemic events, while hoping the increase in bleeding is tolera...

Apixaban Plus Mono Versus Dual Antiplatelet Therapy in Acute Coronary Syndromes Insights From the APPRAISE-2 Trial
ConclusionsPost-ACS treatment with apixaban versus placebo showed no efficacy, but it increased bleeding regardless of concomitant therapy with aspirin alone or aspirin plus clopidogrel. (Apixaban for Prevention of Acute Ischemic Events 2 [APPRAISE-2]; NCT00831441)

Revisiting Sex Equality With Transcatheter Aortic Valve Replacement Outcomes A Collaborative, Patient-Level Meta-Analysis of 11,310 Patients
BackgroundThere has been conflicting clinical evidence as to the influence of female sex on outcomes after transcatheter aortic valve replacement.ObjectivesThe aim of this study was to evaluate the impact of sex on early and late mortality and safety end points after transcatheter aortic valve replacement using a collaborative meta-analysis of patient-level data.MethodsFrom the MEDLINE, Embase, and the Cochrane Library databases, data were obtained from 5 studies, and a database containing individual patient-level time-to-event data was generated from the registry of each selected study. The primary outcome of interest was...

Left Atrial Appendage Closure as an Alternative to Warfarin for Stroke Prevention in Atrial Fibrillation A Patient-Level Meta-Analysis
ConclusionsIn patients with NVAF at increased risk for stroke or bleeding who are candidates for chronic anticoagulation, LAAC resulted in improved rates of hemorrhagic stroke, cardiovascular/unexplained death, and nonprocedural bleeding compared to warfarin.

Double Antiplatelet Therapy Duration Standardize or Personalize? ∗
The duration of dual antiplatelet therapy is the subject of debate. Prolonged dual antiplatelet therapy may prevent recurrence of thrombotic events, such as stroke or myocardial infarction (MI), caused by either iterative plaque rupture or complications related to previous revascularization, with increased risk of bleeding. Multiple factors have to be integrated: type of stent, clinical presentation, type of dual antiplatelet therapy, coronary lesion complexity, and patient compliance. The current European guidelines (1) recommend 6 months’ dual antiplatelet therapy in stable patients with coronary artery disease underg...

Transcatheter Versus Surgical Aortic Valve Replacement in Patients With Severe Aortic Valve Stenosis 1-Year Results From the All-Comers NOTION Randomized Clinical Trial
ConclusionsIn the NOTION trial, no significant difference between TAVR and SAVR was found for the composite rate of death from any cause, stroke, or MI after 1 year. (Nordic Aortic Valve Intervention Trial [NOTION]; NCT01057173)

Duration of Triple Therapy in Patients Requiring Oral Anticoagulation After Drug-Eluting Stent Implantation The ISAR-TRIPLE Trial
ConclusionsSix weeks of triple therapy was not superior to 6 months with respect to net clinical outcomes. These results suggest that physicians should weigh the trade-off between ischemic and bleeding risk when choosing the shorter or longer duration of triple therapy.

Oral Anticoagulation, Aspirin, or No Therapy in Patients With Nonvalvular AF With 0 or 1 Stroke Risk Factor Based on the CHA 2 DS 2 -VASc Score
ConclusionsLow-risk patients (CHA2DS2-VASc = 0 [male], 1 [female]) have a truly low risk for stroke and bleeding. With 1 additional stroke risk factor (CHA2DS2-VASc = 1 [male], = 2 [female]), there was a significant increase in event rates (particularly mortality) if nonanticoagulated.

Randomized Trial of Complete Versus Lesion-Only Revascularization in Patients Undergoing Primary Percutaneous Coronary Intervention for STEMI and Multivessel Disease The CvLPRIT Trial
ConclusionsIn patients presenting for P-PCI with multivessel disease, index admission complete revascularization significantly lowered the rate of the composite primary endpoint at 12 months compared with treating only the IRA. In such patients, inpatient total revascularization may be considered, but larger clinical trials are required to confirm this result and specifically address whether this strategy is associated with improved survival.

Bivalirudin Versus Heparin With or Without Glycoprotein IIb/IIIa Inhibitors in Patients With STEMI Undergoing Primary Percutaneous Coronary Intervention Pooled Patient-Level Analysis From the HORIZONS-AMI and EUROMAX Trials
BackgroundIn the HORIZONS-AMI (Harmonizing Outcomes with RevasculariZatiON and Stents in Acute Myocardial Infarction) trial, 3,602 patients undergoing primary percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI) treated with bivalirudin had lower bleeding and mortality rates, but higher acute stent thrombosis rates compared with heparin + a glycoprotein IIb/IIIa inhibitor (GPI). Subsequent changes in primary PCI, including the use of potent P2Y12 inhibitors, frequent radial intervention, and pre-hospital medication administration, were incorporated into the EUROMAX (European Ambu...
