A central factor in the pathogenesis of heart failure (HF) with reduced ejection fraction is the initial decrease in systolic function. Prior attempts at increasing cardiac contractility with oral drugs have uniformly resulted in signals of increased mortality at pharmacologically effective doses. Omecamtiv mecarbil is a novel, selective cardiac myosin activator that has been shown to improve cardiac function and to decrease ventricular volumes, heart rate, and N-terminal pro-B-type natriuretic peptide in patients with chronic HF. The GALACTIC-HF (Global Approach to Lowering Adverse Cardiac outcomes Through Improving Contractility in Heart Failure) trial tests the hypotheses that omecamtiv mecarbil can safely improve symptoms, prevent clinical HF events, and delay CV death in patients with chronic HF. The GALACTIC-HF trial is an international, multicenter, randomized, double-blind, placebo-controlled, event-driven cardiovascular outcomes trial. More than 8,000 patients with chronic symptomatic (New York Heart Association functional class II to IV) HF, left ventricular ejection fraction ≤35%, elevated natriuretic peptides, and either current hospitalization for HF or history of hospitalization or emergency department visit for HF within a year of screening will be randomized to either oral placebo or omecamtiv mecarbil employing a pharmacokinetic-guided dose titration strategy using doses of 25, 37.5, or 50 mg twice daily. The primary efficacy outcome is the time to cardiovascular death or first HF event. The study has 90% power to assess a final hazard ratio of approximately 0.80 in cardiovascular death, the first secondary outcome. The GALACTIC-HF trial is the first trial examining whether selectively increasing cardiac contractility in patients with HF with reduced ejection fraction will result in improved clinical outcomes.

Transthyretin amyloid cardiomyopathy (ATTR-CM) is a life-threatening, progressive, infiltrative disease caused by the deposition of transthyretin amyloid fibrils in the heart, and can often be overlooked as a common cause of heart failure. Delayed diagnosis due to lack of disease awareness and misdiagnosis results in a poorer prognosis. Early accurate diagnosis is therefore key to improving patient outcomes, particularly in the context of both the recent approval of tafamidis in some countries (including the United States) for the treatment of ATTR-CM, and of other promising therapies under development. With the availability of scintigraphy as an inexpensive, noninvasive diagnostic tool, the rationale to screen for ATTR-CM in high-risk populations of patients is increasingly warranted. Here we propose a framework of clinical scenarios in which screening for ATTR-CM is recommended, as well as diagnostic “red flags” that can assist in its diagnosis among the wider population of patients with heart failure.


The authors sought to confirm a subgroup analysis of the prior FIX-HF-5 (Evaluate Safety and Efficacy of the OPTIMIZER System in Subjects With Moderate-to-Severe Heart Failure) study showing that cardiac contractility modulation (CCM) improved exercise tolerance (ET) and quality of life in patients with ejection fractions between 25% and 45%.


The authors sought to provide the pre-specified primary endpoint of the ROADMAP (Risk Assessment and Comparative Effectiveness of Left Ventricular Assist Device and Medical Management in Ambulatory Heart Failure Patients) trial at 2 years.

The aim of this study was to develop and validate a device-based diagnostic algorithm to predict heart failure (HF) events.
