Randomized Controlled Trial Multicenter Study Clinical TrialBosentan for treatment of inoperable chronic thromboembolic pulmonary hypertension: BENEFiT (Bosentan Effects in iNopErable Forms of chronIc Thromboembolic pulmonary hypertension), a randomized, placebo-controlled trial.
Our goal was to investigate the effect of treatment with the oral dual endothelin receptor antagonist bosentan on the hemodynamics and exercise capacity of patients with chronic thromboembolic pulmonary hypertension (CTEPH). ⋯ This study demonstrated a positive TE of bosentan on hemodynamics in this patient population. No improvement was observed in exercise capacity. Further trials are needed to define the role of medical therapy in patients with CTEPH (Bosentan Effects in Inoperable Forms of Chronic Thromboembolic Pulmonary Hypertension; NCT00313222).

Randomized Controlled Trial Multicenter Study Comparative StudyMultivessel coronary revascularization in patients with and without diabetes mellitus: 3-year follow-up of the ARTS-II (Arterial Revascularization Therapies Study-Part II) trial.
The purpose of this study was to assess the 3-year outcome of coronary artery bypass graft surgery (CABG) and percutaneous coronary intervention (PCI) using sirolimus-eluting stents (SES) in patients who had multivessel coronary artery disease with and without diabetes mellitus. ⋯ At 3 years, PCI using SES for patients with multivessel coronary artery disease seems to be safer and more efficacious than PCI using bare-metal stents, irrespective of the diabetic status of the patient. Hence, PCI using SES appears to be a valuable alternative to CABG for both diabetic and nondiabetic patients.

Randomized Controlled Trial Multicenter StudyRandomized trial of cardiac resynchronization in mildly symptomatic heart failure patients and in asymptomatic patients with left ventricular dysfunction and previous heart failure symptoms.
We sought to determine the effects of cardiac resynchronization therapy (CRT) in New York Heart Association (NYHA) functional class II heart failure (HF) and NYHA functional class I (American College of Cardiology/American Heart Association stage C) patients with previous HF symptoms. ⋯ The REVERSE (REsynchronization reVErses Remodeling in Systolic left vEntricular dysfunction) trial demonstrates that CRT, in combination with optimal medical therapy (+/-defibrillator), reduces the risk for heart failure hospitalization and improves ventricular structure and function in NYHA functional class II and NYHA functional class I (American College of Cardiology/American Heart Association stage C) patients with previous HF symptoms. (REsynchronization reVErses Remodeling in Systolic Left vEntricular Dysfunction [REVERSE]; NCT00271154).
