Randomized Controlled Trial Comparative Study
Health Status Benefits of Transcatheter vs Surgical Aortic Valve Replacement in Patients With Severe Aortic Stenosis at Intermediate Surgical Risk: Results From the PARTNER 2 Randomized Clinical Trial.
In patients with severe aortic stenosis (AS) at intermediate surgical risk, treatment with transcatheter aortic valve replacement (TAVR) or surgical aortic valve replacement (SAVR) results in similar 2-year survival. The effect of TAVR vs SAVR on health status in patients at intermediate surgical risk is unknown. ⋯ Among intermediate-risk patients with severe AS, health status improved significantly with both TAVR and SAVR through 2 years of follow up. Early health status improvement was greater with TAVR, but only among patients treated via transfemoral access. Longer term follow-up is needed to assess the durability of quality-of-life improvement with TAVR vs SAVR in this population.

High-intensity statins are recommended following myocardial infarction. However, patients may not continue taking this medication with high adherence. ⋯ Many patients filling high-intensity statins following a myocardial infarction do not continue taking this medication with high adherence for 2 years postdischarge. Interventions are needed to increase high-intensity statin use and adherence after myocardial infarction.

The randomized clinical trials comparing nonvitamin K antagonist oral anticoagulants (NOACs) vs warfarin largely focused on recruiting high-risk patients with atrial fibrillation with more than 2 stroke risk factors, with only the trials testing dabigatran or apixaban including few patients with 1 stroke risk factor. Despite this, regulatory approvals of all NOACs have been based on stroke prevention for patients with atrial fibrillation with 1 or more stroke risk factors. ⋯ In this Danish cohort study of patients with atrial fibrillation and a single stroke risk factor, there was no difference between NOACs compared with treatment with warfarin in terms of the risk of having an ischemic stroke/systemic embolism. For "any bleeding," this was lower for treatment with apixaban and dabigatran compared with warfarin. These data do not allow for a definitive statement of the comparative effectiveness or safety of NOACs because of the possible residual confounding that was unmasked with falsification outcomes.

Women with acute myocardial infarction (MI) undergoing mechanical reperfusion remain at increased risk of adverse cardiac events and mortality compared with their male counterparts. Whether the benefits of new-generation drug-eluting stents (DES) are preserved in women with acute MI remains unclear. ⋯ New-generation DES are associated with consistent and durable benefits over 3 years in women presenting with acute MI. The magnitude of these benefits appeared to be greater per increase in severity of acute coronary syndrome.

One-Year Mortality for Bivalirudin vs Heparins Plus Optional Glycoprotein IIb/IIIa Inhibitor Treatment Started in the Ambulance for ST-Segment Elevation Myocardial Infarction: A Secondary Analysis of the EUROMAX Randomized Clinical Trial.
Uncertainty exists regarding potential survival benefits of bivalirudin compared with heparin with routine or optional use of glycoprotein IIb/IIIa inhibitors (GPIs) in patients with ST-segment elevation myocardial infarction (STEMI). Few data are available regarding long-term mortality in the context of contemporary practice with frequent use of radial access and novel platelet adenosine diphosphate P2Y12 receptor inhibitors. ⋯ In patients with STEMI who were being transported for primary percutaneous coronary intervention, treatment with bivalirudin or with heparin with optional use of GPI resulted in similar 1-year mortality. The reduced composite end point of death and/or major bleeding at 30 days in the bivalirudin arm of the EUROMAX trial did not translate into reduced cardiovascular or all-cause death at 1 year.
