Testing the effectiveness of cardiac resynchronization therapy in heart failure

The purpose of this study is to test the comparative effectiveness of two types of cardiac resynchronization therapy (CRT) lead implantations (His vs LBBP) in relation to patient-centered outcomes (e.g. quality of life, physical activity, heart failure hospitalization, mortality) and comparative safety in relation to device-related complications and re-interventions (e.g. lead dislodgement, infection) relative to standard of care biventricular pacing.

Effect of Adaptive Servo Ventilation (ASV) on Survival and Hospital Admissions in Heart Failure (ADVENT-HF)

Sleep Apnea (SA) is a disorder that causes pauses in breathing during sleep that expose the heart to oxygen deprivation. It is common in patients with heart failure (HF) where it is associated with increased risk of hospitalizations and death. It is not known however whether treating SA reduces these risks. This study is looking at whether a respiratory device known as Adaptive Servo Ventilation (ASV) can reduce the rate of cardiovascular hospitalizations and death in subjects with HF and SA.

Rhythm Control - Catheter Ablation With or Without Anti-arrhythmic Drug Control of Maintaining Sinus Rhythm Versus Rate Control With Medical Therapy and/or Atrio-ventricular Junction Ablation and Pacemaker Treatment for Atrial Fibrillation (RAFT-AF)

Atrial fibrillation and heart failure are two common heart conditions that are associated with an increase in death and suffering. When both of these two conditions occur in a patient the patient's prognosis is poor. These patients have poor life quality and are frequently admitted to the hospital. The treatment of atrial fibrillation in heart failure patients is extremely challenging.

A Study of Vericiguat in Participants With Heart Failure With Reduced Ejection Fraction (HFrEF) (MK-1242-001) (VICTORIA)

This is a randomized, placebo-controlled, parallel-group, multi-center, double-blind, event driven study of vericiguat (MK-1242) in participants with HFrEF. The primary hypothesis is vericiguat (MK-1242) is superior to placebo in increasing the time to first occurrence of the composite of cardiovascular (CV) death or heart failure (HF) hospitalization in participants with HFrEF.

INfluenza Vaccine to Effectively Stop Cardio Thoracic Events and Decompensated Heart Failure (INVESTED)

INVESTED will test the hypothesis that high dose trivalent influenza vaccine will reduce cardiopulmonary events to a greater extent than standard dose quadrivalent influenza vaccine in high-risk cardiovascular patients with a recent history of myocardial infarction or heart failure. The trial will enroll 9300 participants over one Vanguard (pilot) season and three additional influenza seasons. The primary endpoint will be a composite of all-cause mortality or cardiopulmonary hospitalization.

AdaptResponse Clinical Trial

The purpose of this clinical study is to test the hypothesis that market released Cardiac Resynchronization Therapy (CRT) devices which contain the AdaptivCRT® (aCRT) algorithm have a superior outcome compared to standard CRT devices in CRT indicated patients with normal atrio-ventricular (AV) conduction and left bundle branch block (LBBB).

Resynchronization/Defibrillation for Ambulatory Heart Failure Trial in Patients With Permanent Atrial Fibrillation (RAFT-PermAF)

Atrial fibrillation (AF) and heart failure (HF) are two common heart conditions that are encountered with an increase in death and suffering. When both these two conditions occur in a patient, the patient's prognosis is poor with a reduced quality of life. These patients are frequently admitted to the hospital and have increased risk of death. In these HF patients who are in AF all of the time, who would otherwise be a suitable candidate for an implantable defibrillator to prevent sudden cardiac death, whether adding pacing of both ventricles will reduce death and suffering.
