CairoAges 18 years+ - NCT07219511RecruitingPhase 1
Safety study of VS-041 for heart failure with preserved pumping strength
This trial tests an investigational drug called VS-041 to see if it's safe and helps people with a type of heart failure where the heart pumps well but doesn't relax properly (HFpEF). It may be an option if you are 50 or older and have stable heart failure symptoms.
Little Rock, ArkansasAges 50 years+ - NCT06414759RecruitingPhase 4
Combination diuretic therapy for heart failure fluid overload
This trial tests a combination of water pills (diuretics) to help remove extra fluid in people hospitalized with acute decompensated heart failure (sudden worsening of heart failure). It aims to find a safe and effective way to reduce swelling and fluid buildup.
Giza, GZAges 18–65 - NCT06587854Recruiting
Study on fluid congestion in acute heart failure patients
This study looks at different patterns of fluid buildup in people with acute heart failure. It aims to understand how these patterns relate to treatment with water pills (diuretics) and may help improve care.
GroningenAges 18 years+ - NCT06595290Recruiting
Faster medication increase for heart failure with weak pumping
This trial tests a new, faster way to increase heart failure medications during a hospital stay, aiming to get patients on the right doses sooner. It is for people with weak heart pumping (ejection fraction 40% or less) who are currently in the hospital for heart failure and are on low doses of standard medications.
Long Xuyen, An GiangAges 18–75 - NCT07682298Recruiting
Measuring leftover fluid in hospitalized heart failure patients
This study looks at how well we can measure leftover fluid in the body in people hospitalized for heart failure with fluid overload. It aims to help doctors better manage treatment and improve recovery.
AarhusAges 18 years+ - NCT02898181Recruiting
Ear cartilage stimulation for sudden heart failure worsening
This trial tests whether a gentle stimulation near your ear (on the tragus, a small ear area) can help people whose heart failure has recently gotten worse while in the hospital. If it works, it may improve symptoms and recovery during this acute phase.
Oklahoma City, OklahomaAges 18–80 - NCT06414928Recruiting
Predicting Outcomes in Heart Failure Patients
This study is looking at people with heart failure who come to the emergency room at NICVD in Karachi. The researchers want to build a simple tool to predict how heart failure patients will do over the next 30 days, which may help guide better care.
Karachi, SindhAges 18 years+ - NCT04332692Recruiting
Check if a lung ultrasound helps evaluate discharge after heart failure
This study looks at whether doing lung ultrasounds can better assess people right before they leave the hospital after an acute heart failure flare. It may help doctors decide when someone is ready for discharge and tailor care to reduce risk after leaving.
Vandœuvre-lès-NancyAges 18 years+ - NCT07577596RecruitingPhase 4
Continuous Furosemide Infusion for Heart Failure Fluid Overload
This study tests whether giving furosemide (a water pill) as a continuous IV drip works better than standard doses for patients hospitalized with heart failure and fluid buildup. The goal is to help your body get rid of excess fluid more effectively.
RandersAges 18 years+ - NCT07057323Enrolling by invitation
Coronary sinus reducer for heart failure with preserved pumping function
This trial tests a device placed in a heart vein to improve symptoms in people whose heart pumps normally but still causes shortness of breath and fatigue. The device may help relieve pressure in the heart and improve daily life.
Rochester, MinnesotaAges 18 years+ - NCT07069738Recruiting
New pacemaker vs standard cardiac therapy for heart failure
This study tests a newer type of pacemaker that paces the heart's left bundle branch area, compared to the usual cardiac resynchronization therapy. It is for people with heart failure who need a combined pacemaker-defibrillator (CRT-D) and have a specific heart rhythm pattern (left bundle branch block) with reduced pumping strength.
Huntsville, AlabamaAges 18 years+ - NCT05677100Recruiting
Aortix device for acute heart failure
This trial is testing a small pump placed in the aorta to help the kidneys remove extra fluid when standard IV diuretics aren't working well enough for severe heart failure. It may help you if you're hospitalized and still very congested (swollen, fluid buildup) despite strong water pills.
Phoenix, ArizonaAges 21 years+ - NCT06736574RecruitingPhase 3
Study of omecamtiv mecarbil for chronic heart failure with very weak heart pump
This study tests an investigational medicine (omecamtiv mecarbil) for people with chronic heart failure and very low pumping strength. It looks at whether the drug can help prevent heart failure events or the need for stronger treatments.
Alexander City, AlabamaAges 18–85 - NCT07499661Recruiting
Study of blood clots in the lungs with heart failure
This study looks at whether a blood clot in the lungs (pulmonary embolism) is a hidden cause in patients who are hospitalized for acute heart failure. It involves additional imaging tests to find a clot if present, which could change your treatment.
AgenAges 18 years+ - NCT07550790Recruiting
Preventing kidney injury during heart failure imaging scans
This study tests whether a specific water-based medication can prevent kidney damage when patients with acute heart failure need a CT scan with contrast dye. The trial focuses on people with mild-to-moderate kidney problems who are hospitalized for fluid buildup in the heart.
Seongnam-si, Gyeonggi-doAges 20 years+ - NCT03103932Recruiting
Blood test–guided discharge for people hospitalized with heart failure
This trial checks whether using a blood test (a “biomarker”) can help doctors decide when it’s safe to send people home after a hospital stay for worsening heart failure. It may help reduce avoidable readmissions while keeping you safe.
Ottawa, OntarioAges 18 years+ - NCT03323216Recruiting
Testing heart-related blood markers in people with diabetes and heart failure
This study looks for blood markers that may help explain or predict heart problems in people who have type 2 diabetes and heart failure. To join, you may also need to be having a planned heart procedure where doctors can collect study information.
