Acute Hemodynamic Effects of Sacubitril-Valsartan In Heart Failure Patients Receiving Intravenous Vasodilator and Inotropic Therapy.

Background: Prior study has demonstrated that transitioning patients in acutely decompensated heart failure with a low cardiac output directly from intravenous (i.v.) vasoactive (ie, vasodilators or inotropes) drugs to sacubitril-valsartan (S/V) can be done safely with tolerance to the 1-month follow-up.

Morbid Obesity as a Therapeutic Target for Heart Failure.

Purpose Of Review: This review will define morbid obesity and relationship between morbid obesity and heart failure syndromes. It will delve into unique challenges facing patients with dual diagnoses of heart failure and morbid obesity and examine the data that obesity should be a target in the treatment of heart failure.

Recent Findings: Emerging literature has indicated the safety and efficacy of surgical weight loss in patients with heart failure.

How to Optimize Patient Selection and Device Performance of the Newest Generation Left Ventricular Assist Devices.

Purpose Of Review: This review will discuss key differences of third-generation left ventricular assist devices (LVADs), identify patient selection considerations to optimize post-implant clinical outcomes, and summarize key echocardiographic and hemodynamic parameters to guide device optimization.

Recent Findings: There are major engineering differences between the third-generation LVADs which contribute to unique pump operational characteristics. Improved hemocompatibility has led to reduction in hemocompatibility-related adverse events (HRAEs), particularly for the Heartmate 3 pump.

Metabolic Biomarkers in Heart Failure.

Metabolomics is the study of small, organic molecules within biochemical pathways. With advancement of technology, nuclear magnetic resonance, gas chromatography, and mass spectrometry have allowed for the discovery and analysis of large databases of metabolites implicated in heart failure. Metabolomics also explores the patient and environment interactions and unlocks the link between environmental exposures and the development of cardiovascular disease.

Contemporary Controversies in Digoxin Use in Systolic Heart Failure.

Digoxin remains one of the oldest therapies for heart failure; however, its safety and efficacy have been controversial since its initial use. Questions that remain include the clinical efficacy of digoxin when added to contemporary medical therapy, when and if it should be added, and how to minimize adverse effects. In this review, we will summarize recent data on the use of digoxin in systolic heart failure and address some of the controversies regarding the role of digoxin in the modern era of heart failure treatment.
