Omecamtiv Mecarbil Has Biggest Benefit at Lowest EFs

May 18, 2021 When omecamtiv mecarbil is used in patients who have chronic heart failure with reduced ejection fraction (HFrEF), the greater beneficial impact on clinical outcomes is seen in those with lower ejection fractions, a secondary analysis of the placebo-controlled GALACTIC-HF trial shows. Among the prespecified subgroups in the trial, LVEF was the strongest modifier of the treatment effect, with larger reductions in the risk of HF events or CV death observed as values fell ( P = 0.004 for interaction). Reductions in NT-proBNP were greater at the lower end of the range, as well, John Teerlink, MD (San Francisco VA Medical Center and the University of California, San Francisco), reported during the recent virtual American College of Cardiology (ACC) 2021 Scientific Session.

Falling Through the Cracks on Rapid Troponin Testing Protocols

email article Transitioning high-sensitivity troponin testing protocols in the emergency department for suspected acute coronary syndrome can have some unintended consequences, studies showed. In a prospective multicenter trial from Australia, patients randomized to a 0/1-hour high-sensitivity cardiac troponin-T (hs-cTnT) protocol unmasked to the care team had similar all-cause mortality and MI at 12 months as those whose early levels were masked and were treated based on the standard protocol of 0/3-hour testing (5.0% vs 3.8%, HR 1.32, 95% CI 0.95-1.83). However, for those with an intermediate elevation in troponin of less than 29 ng/L the only group for whom results differed between the two trial arms, with reporting to
