Newest Heart Failure With Reduced Ejection Fraction (HFrEF) clinical trials
All recruiting trials (14)
-
Atrial Shunt to Help Heart Failure With Reduced Ejection Fraction
This study tests whether an atrial shunt implanted after heart catheterization helps people with HFrEF when added to standard heart failure therapy.
-
Achieving Optimal Medical Therapy Through Transcatheter Mitral Repair in HFrEF
This trial tests whether early transcatheter edge-to-edge repair (M-TEER) helps patients with HFrEF and secondary MR reach guideline-directed medical therapy faster and more completely, and whether that improves quality of life and outcomes.
-
CRD-4730 for heart failure with reduced ejection fraction
This trial tests CRD-4730 versus placebo to see if it helps adults with HFrEF who are already on standard heart failure therapy.
-
Olive oil supplementation during cardiac rehab for heart failure with reduced ejection fraction
This study tests whether adding extra-virgin olive oil during a cardiac rehabilitation program is doable and helpful for people with HFrEF.
-
Remote-guided medication up-titration for people with reduced ejection fraction heart failure
This trial will see if telemedicine follow-up helps clinicians start and increase guideline-recommended heart failure medicines faster and more completely in adults with newly diagnosed HFrEF.
-
Vericiguat for right‑ventricular function and heart remodeling in HFrEF
This study will test whether adding vericiguat to usual heart‑failure treatment helps adults with stable HFrEF improve right‑ventricular function and heart remodeling over 12 months.
-
Nerve ablation for heart failure with reduced ejection fraction using the right greater splanchnic nerve
This early-stage, catheter-based test looks at whether ablating the right greater splanchnic nerve can help people 40 and older with HFrEF and is done in a randomized, sham-controlled setup.
-
Intensive GDMT optimization for women after heart failure hospitalization
This study tests whether rapidly increasing and closely monitoring heart failure meds in women after hospitalization can reduce death or readmission within a year.
-
Once-daily versus twice-daily ramipril for kidney health in CKD patients with reduced ejection fraction heart failure
This trial tests whether taking ramipril once a day or split into twice-daily doses better protects kidney function in adults who have chronic kidney disease and heart failure with reduced ejection fraction.
-
SmartSignalHF remote monitoring for people with implanted ICD or CRT‑D and heart failure
This tests whether SmartSignalHF remote monitoring for people with implanted ICD or CRT‑D and chronic heart failure can reduce deaths and heart failure hospital visits over 12 months compared with standard remote monitoring.
-
AI analysis of ECGs to detect structural heart disease
This project will test whether AI can read traditional and wearable ECGs to find undiagnosed valve disease, pulmonary hypertension, and heart failure in adults.
-
Carvedilol versus metoprolol succinate in people with heart failure and an implanted defibrillator
This study will test whether switching from metoprolol succinate to carvedilol reduces ICD therapies, heart-related hospitalizations, or cardiovascular death in adults with HFrEF and an ICD.
-
AI-driven wearable monitoring for chronic heart failure
This project will try an AI-driven wearable and mini‑invasive device to see if continuous home monitoring reduces hospital visits and improves health for adults with chronic heart failure.
-
Investigating heart function improvement in patients with specific heart pacing methods
This study tests whether a new heart pacing method can help people with heart failure feel better compared to the standard pacing method.
