Multi-lead ECG to Effectively Optimize Resynchronization Devices: New CRT Recipients
Heart FailureSystolicCardiac resynchronization therapy (CRT), or atrial-synchronized biventricular (BiV) pacing, is an FDA-approved device therapy option for heart failure (HF) patients with reduced left ventricular ejection fraction and electrical dyssynchrony. A traditional CRT device has pacing leads implanted within the right atrium (RA), the right ventricle (RV), and within a coronary vein overlying the lateral or posterior left ventricle (LV). Within the past decade, various multi-center randomized controlled trials have reported improved quality of life, aerobic exercise capacity, LV systolic function and structure, as well as decreased hospitalization rates and mortality among patients with HF. Despite improvements in CRT technology with multipoint pacing, quadripolar leads, and adaptive pacing algorithms, approximately 30% of patients do not clinically benefit and are considered non-responders. This study looks to optimize new CRT device recipients using information obtained from standard ECG machines.
Direct HIS/LBB Pacing as an Alternative to Biventricular Pacing in Patients With HFrEF and a Typical...
Heart FailureLeft Bundle-Branch BlockThe study will investigate the feasibility of using direct HIS pacing or left bundle branch pacing (LBB pacing) as an alternative to biventricular pacing in patients with symptomatic heart failure and an ECG with a typical left bundle branch block pattern.
Effect of Dapagliflozin on Submaximal Exercise Tolerance in Heart Failure
HFrEFThis study will examine whether and how the FDA-approved drug dapagliflozin (Dapa) improves submaximal exercise endurance and skeletal muscle oxidative phosphorylation capacity (SkM OxPhos) in patients with heart failure and reduced left ventricular ejection fraction (HFrEF).
Matching Perfusion and Metabolic Activity in HFpEF
Heart Failure With Preserved Ejection FractionThis study will test whether pharmacologic agents that increase perfusion [Potassium Nitrate (KNO3)], with and without additional supplements that may improve mitochondrial function [Propionyl-L-Carnitine (PLC) and Nicotinamide Riboside (NR)], improve submaximal exercise endurance and skeletal muscle oxidative phosphorylation capacity (SkM OxPhos) in participants with Heart Failure with Preserved Ejection Fraction (HFpEF).
Inferior Vena CAVA and Lung UltraSound-guided Therapy in Acute Heart Failure
Heart FailureAcute Heart FailureBetween 25% and 30% of patients hospitalized for acute heart failure (AHF) are readmitted within 90 days after discharge. Mostly due to persistent congestion on discharge. However, as the optimal evaluation of decongestion is not clearly defined, it is necessary to implement new tools to identify subclinical congestion to guide treatment.
HF Patients With LVADs Being Treated With SGLT2i
Heart Failure With Reduced Ejection FractionThe main purpose of this study is to observe outcomes of sodium-glucose co-transporter 2 inhibitors (SGLT2i) in heart failure (HF) patients with left ventricular assist devices (LVAD).
Remote Dielectric Sensing (ReDS) Assisted Diuresis in Acute Decompensated Heart Failure
Heart Failure; With DecompensationThis study evaluates the use of a wearable vest capable of non-invasively measuring lung fluid content in hospitalized patients with heart failure
Study on Early Intra-aortic Balloon Pump Placement in Acute Decompensated Heart Failure Complicated...
Cardiogenic ShockThe aim of the study is to demonstrate the superiority of early intra-aortic balloon pump implantation at admission over local clinical practice (pharmacological only) in acute decompensated heart failure patients with cardiogenic shock, with respect to 60-day survival or successful bridge to heart replacement therapies (heart transplant or Left Ventricular Assist Device implantation).
Comparison of PEEP in Acute Decompensated Heart Failure
Heart DecompensationMechanical Ventilation Pressure HighLittle is known about optimal level of positive end-expiratory pressure (PEEP) in patiens who recieved invasive mechanical ventilation for acute decompensated heart failure. We therefore sought to compare clinical outcome according to low versus high PEEP.
COPILOT-HF: Cooperative Program for ImpLementation of Optimal Therapy in Heart Failure
Heart FailureThis is a randomized, open-label, initiative within the Mass General Brigham healthcare system testing two remote care strategies for optimizing the prescription of guideline-directed medical therapies in patients with heart failure, regardless of left ventricular ejection fraction (LVEF).
