Complete vs. Infarct-related, Artery-only Revascularization in STEMI
Researchers randomized patients with ST elevation myocardial infarction and at least one noninfarct artery with angiographically significant stenosis to either fractional flow-reserve-guided complete revascularization by percutaneous coronary intervention or to no revascularization of noninfarct arteries.

Predicting Electrical Cardioversion Failure
A study of the 30-day success rate of electrical cardioversion of acute atrial fibrillation revealed five clinical predictors of recurrence.

Cardiac Resynchronization Therapy Reduces New Onset Ventricular Arrhythmias
In an analysis of the landmark Resynchronization in Ambulatory Heart Failure Trial, patients without prior ventricular arrhythmias randomized to cardiac resynchronization therapy experienced significantly less new onset ventricular arrhythmias than those randomized to implantable cardioverter defibrillator alone.

Can Echo/Doppler Accurately Estimate LVEDP in Pulmonary Hypertension Patients?
In patients with pulmonary hypertension evaluated in a specialty clinic, echo/Doppler estimation of left ventricular end-diastolic pressure is not reliable for the determination of pre- vs. post-capillary pulmonary hypertension.

Tolvaptan Fails to Improve Dyspnea in Acute Heart Failure
In patients hospitalized for acute heart failure, adding tolvaptan to furosemide lead to increased weight and fluid loss, but did not improve dyspnea at 24 hours.
