Randomized Controlled Trial Comparative StudyAcute cardioversion vs a wait-and-see approach for recent-onset symptomatic atrial fibrillation in the emergency department: Rationale and design of the randomized ACWAS trial.
Current standard of care for patients with recent-onset atrial fibrillation (AF) in the emergency department aims at urgent restoration of sinus rhythm, although paroxysmal AF is a condition that resolves spontaneously within 24 hours in more than 70% of the cases. A wait-and-see approach with rate-control medication only and when needed cardioversion within 48 hours of onset of symptoms is hypothesized to be noninferior, safe, and cost-effective as compared with current standard of care and to lead to a higher quality of life. ⋯ The ACWAS trial aims at providing evidence for the use of a wait-and-see approach for patients with recent-onset symptomatic AF in the emergency department.

Randomized Controlled Trial Multicenter StudyLevosimendan in patients with left ventricular systolic dysfunction undergoing cardiac surgery on cardiopulmonary bypass: Rationale and study design of the Levosimendan in Patients with Left Ventricular Systolic Dysfunction Undergoing Cardiac Surgery Requiring Cardiopulmonary Bypass (LEVO-CTS) trial.
Low cardiac output syndrome is associated with increased mortality and occurs in 3% to 14% of patients undergoing cardiac surgery on cardiopulmonary bypass (CPB). Levosimendan, a novel calcium sensitizer and KATP channel activator with inotropic, vasodilatory, and cardioprotective properties, has shown significant promise in reducing the incidence of low cardiac output syndrome and related adverse outcomes in patients undergoing cardiac surgery on CPB. ⋯ ClinicalTrials.gov (NCT02025621).

Randomized Controlled Trial Multicenter StudySafety of 6-month duration of dual antiplatelet therapy after percutaneous coronary intervention in patients with acute coronary syndromes: Rationale and design of the Smart Angioplasty Research Team-safety of 6-month duration of Dual Antiplatelet Therapy after percutaneous coronary intervention in patients with acute coronary syndromes (SMART-DATE) prospective multicenter randomized trial.
Dual antiplatelet therapy (DAPT) is a fundamental treatment that optimizes clinical outcomes after percutaneous coronary intervention, especially in patients with acute coronary syndrome (ACS). Although current international guidelines recommend DAPT for at least 12 months after implantation of a drug-eluting stent in patients with ACS, these recommendations are not based on randomized controlled trials dedicated to ACS population. ⋯ The SMART-DATE randomized trial is the first study exploring the safety of 6-month DAPT compared with conventional 12-month or longer DAPT dedicated to patients with ACS after second-generation drug-eluting stent implantation.

Randomized Controlled TrialTicagrelor with aspirin or alone in high-risk patients after coronary intervention: Rationale and design of the TWILIGHT study.
Dual antiplatelet therapy (DAPT) is necessary to prevent thrombosis yet increases bleeding after percutaneous coronary intervention (PCI) with drug-eluting stents (DES). Antiplatelet monotherapy with a potent P2Y12 receptor antagonist may reduce bleeding while maintaining anti thrombotic efficacy compared with conventional DAPT. ⋯ TWILIGHT is the largest study to date that is specifically designed and powered to demonstrate reductions in bleeding with ticagrelor monotherapy versus ticagrelor plus ASA beyond 3 months post-procedure in a high-risk PCI population treated with DES. The trial will provide novel insights with respect to the potential role of ticagrelor monotherapy as an alternative for long-term platelet inhibition in a broad population of patients undergoing PCI with DES.
