Recruiting studies
- 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+ - NCT06517186Recruiting
Heart failure study with preserved pumping function
This study looks at how the heart muscle works in people with a type of heart failure where the heart pumps normally but doesn't fill properly. It aims to understand the cause better, which could lead to new treatments.
Chicago, IllinoisAges 30 years+ - NCT06285760Recruiting
Acetazolamide for fluid removal in acute heart failure
This study tests whether adding acetazolamide (a different type of water pill) to your current treatment helps remove extra fluid from your body more effectively when you are in the hospital for heart failure.
MadridAges Any age - NCT06176131Recruiting
Telemedicine support for heart failure after hospital
This study tests a care program that uses telemedicine to help people with serious heart failure stay stable after leaving the hospital. It focuses on those who needed multiple hospital stays recently.
FrederiksbergAges Any age - NCT06051058Recruiting
App for managing health after hospital discharge
This study tests a smartphone app designed to help people with multiple health conditions manage their care after leaving the hospital. It may help you feel more supported and avoid confusion during the transition from hospital to home.
Boston, MassachusettsAges 55 years+ - NCT05873634Recruiting
Using health records and testing to study heart failure types
This study combines electronic health record data and detailed heart testing to better understand different heart failure types and what treatments may work best for each. It mainly enrolls people with known heart failure, and also some people without heart failure for comparison.
Sacramento, CaliforniaAges 30 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+ - NCT04982419RecruitingPhase 2/Phase 3
Remote arm treatment to protect heart and kidneys in heart failure
This trial tests whether a simple “arm cuff” treatment done before a heart artery procedure can help protect the kidneys and the heart in people with congestive heart failure. If it works, it may lower the chance of kidney injury around the time of the scan/stent procedure.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT05507879Recruiting
Breast cancer heart monitoring to predict heart damage risk
This trial studies how a blood test marker (TRPC6) may help predict and prevent heart muscle damage and heart failure related to some breast cancer medicines. You may join if you’re starting or have received treatment that can stress the heart, or if you already have signs of treatment-related heart problems.
Gainesville, FloridaAges 18 years+ - NCT05276219RecruitingPhase 4
Vasodilators or diuretics for acute heart failure
This trial compares two treatments for sudden heart failure symptoms like severe shortness of breath. It aims to see whether opening blood vessels or using a water pill works better to relieve congestion and improve breathing.
Copenhagen, CopenhagenAges 18 years+ - NCT01759225Enrolling by invitation
Registry study of people with heart and blood vessel disease
This is a registry (a study that collects health information) for people with certain heart and blood vessel conditions. It may help researchers better understand who has these diseases, how they are managed, and outcomes over time.
Tel AvivAges Any age - NCT00762333Recruiting
Blood tests after a heart attack to study heart strain markers
This study looks at blood test “markers” soon after an acute heart attack, to better understand heart damage and whether heart failure is present. It may help doctors improve how they monitor recovery and risk in people after a heart attack.
Farmington, ConnecticutAges 18 years+ - NCT01099982Recruiting
Studying heart tissue and blood changes after advanced heart care
This trial studies how blood and heart tissue change in people with advanced heart failure who are getting an LVAD (a heart pump) or a heart transplant. It may help doctors better understand what’s happening in the heart before and after these treatments.
Murray, UtahAges 13 years+ - NCT07692256RecruitingPhase 2
Empagliflozin for heart failure in children
This trial tests if empagliflozin, a diabetes medicine that also helps the heart, can improve symptoms in children with heart failure. It may help kids with severe symptoms or high levels of a heart stress marker called BNP.
Cairo, Cairo GovernorateAges 1 month–18 years - NCT07552142Recruiting
Heart Failure Check-In: Using Questionnaires to Spot Early Warning Signs
This study asks heart failure patients who recently were hospitalized to answer regular questionnaires about how they're feeling. Researchers want to see if these questions can detect when heart failure is getting worse before a patient needs emergency care.
Moscow, Non-US/Non-CanadianAges 18 years+ - NCT06783166RecruitingPhase 2/Phase 3
Comparing two medications for acute heart failure with fluid buildup
This trial tests if dapagliflozin or acetazolamide works better for people hospitalized with heart failure who have extra fluid in their body (congestion). The study will compare how well each medication helps remove fluid when used with standard IV diuretics.
Al MansurahAges 18 years+ - NCT07400991Recruiting
Restrictive vs liberal fluids for hospitalized heart failure
This trial studies whether drinking less fluid (restrictive) vs. the usual amount (liberal) helps people hospitalized with heart failure. It aims to find out which approach leads to better recovery and fewer symptoms.
HerningAges 18 years+ - NCT06653725RecruitingPhase 2
Ketone supplement study for hospitalized heart failure patients
This trial tests if a ketone supplement can help people hospitalized for acute heart failure. The supplement is given orally and aims to support the heart and energy levels during recovery.
AalborgAges 18 years+ - NCT02638142Recruiting
Testing IV diuretic treatment for sudden worsening heart failure
This trial studies how an IV (into-the-vein) “water pill” (furosemide/loop diuretic) works in people whose heart failure has suddenly gotten worse. It may help doctors find the best way to reduce fluid-related symptoms like breathing trouble and swelling.
Chioggia, VeneziaAges 18 years+ - NCT06555757Recruiting
Using AI and sound to predict heart failure worsening
This trial uses a smartphone app to record sounds from your chest and breathing. An AI system will analyze these sound patterns to predict when heart failure symptoms might get worse, so you can get help sooner.
Cambridge, CambridgeshireAges 18 years+ - NCT06222099Recruiting
Heartfelt study for chronic heart failure with swelling and adherence challenges
This trial tests a program to help people with chronic heart failure who have swelling in their feet and legs and struggle to follow their care plan. It aims to reduce hospital visits by improving daily monitoring and medication use.
Little Rock, ArkansasAges 22 years+ - NCT06092437Recruiting
Testing a personalized diuretic plan for acute heart failure
This trial is testing whether a diuretic (water pill) dose tailored to each patient works better for treating fluid buildup during a heart failure flare-up. It may help you get the right amount of medication faster and avoid complications.
Heerlen, LimburgAges 18 years+ - NCT05392764RecruitingPhase 3
SGLT2 medicine for high-risk people after sudden worsening heart failure
This Phase 3 trial tests whether starting an SGLT2 inhibitor early in the hospital can improve outcomes for people at high risk after acute (sudden) heart failure. If you qualify, you would be randomized to receive the study medicine or standard care, started within 12 hours of admission.
Anjo, Aichi-kenAges 20 years+ - NCT06218199RecruitingPhase 4
Diuretics vs. blood pressure meds for HeartLogic alerts
This trial compares two treatments—diuretics (water pills) and a blood pressure medication called sacubitril/valsartan—to see which works better when your heart device sends an alert. It's for people with a Boston Scientific heart device that has HeartLogic alerting turned on.
