Test blood markers to understand progression to heart failure
This study looks at blood “markers” (substances in the blood) to help explain how some people move from early heart strain to full heart failure. You may be enrolled if you have stable or worsening heart failure symptoms, or you may qualify as a healthy control for comparison.
Farmington, ConnecticutAges 18 years+ - NCT07513883RecruitingPhase 4
Reducing Heart Failure Medications When Your Heart Recovers
This study tests whether patients whose heart failure has improved can safely reduce some of their medications. If your heart function has recovered significantly and stayed stable, this trial explores whether you can gradually lower doses of heart failure drugs while staying healthy.
GenkAges 18 years+ - NCT07050706Enrolling by invitation
Heart failure and protein levels in the blood
This trial checks if a protein called PRMT5 in the blood is linked to heart function in people with heart failure. It compares healthy volunteers and those with heart failure to see if this protein can help understand the condition better.
Shenzhen, GuangdongAges 18 years+ - NCT06937320Enrolling by invitationPhase 2
Testing ketone supplements for heart failure with preserved ejection fraction (HFpEF)
This study tests whether a special dietary supplement (ketone esters) can improve exercise ability and heart function in people with a type of heart failure where the heart pumps well but is stiff (HFpEF). You might join if you have stable symptoms, an ejection fraction of 50% or higher, and signs of fluid buildup in the heart.
Durham, North CarolinaAges 18 years+ - NCT05585125Enrolling by invitationPhase 4
Testing an informed approach for older adults with HFpEF
This study looks at an “informed” approach to help manage HFpEF (a type of heart failure) in people age 65 and older. It checks whether a structured plan and monitoring are practical and safe for you over time.
New York, New YorkAges 65 years+ - NCT05966415RecruitingPhase 2
Endocalyx for heart failure with fluid overload
This Phase 2 study tests Endocalyx to treat people with heart failure who currently show signs of fluid buildup (congestion). If you qualify, you may help researchers see whether this supplement can improve symptoms and heart-failure–related measurements.
Amsterdam, North HollandAges 18–110 - NCT05802849RecruitingPhase 4
Oral acetazolamide for worsening heart failure
This trial tests whether taking acetazolamide by mouth can help prevent or improve worsening (decompensation) of heart failure after you needed IV water pills (diuretics). It’s mainly for adults with a recent heart-failure flare and specific heart/lab signs, while carefully excluding certain low blood pressure, kidney issues, and electrolyte or acid–base problems.
SamaraAges 18 years+ - NCT07325942Recruiting
Low vs high volume high-intensity interval training for heart failure
This study compares two different types of high-intensity interval exercise programs (one shorter, one longer) in people with chronic heart failure. It aims to see which program improves heart health and daily function more.
Cairo, Giza GovernorateAges 18 years+ - NCT04405583Recruiting
Follow-up study for a heart device in heart failure patients
This study follows people with chronic heart failure to see how well an implanted device (called the Occlutech AFR) works and whether it is safe over time. It may help doctors better understand who benefits and how to manage treatment safely.
BesançonAges 18 years+ - NCT06364644Recruiting
Reducing heart failure risk in low-income adults with diabetes
This study looks at how low income and diabetes together raise the risk of heart failure. It offers a program to help you manage your health and reduce that risk.
Baltimore, MarylandAges 30–70 - 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 - NCT07243769Recruiting
Comparing exercise types for heart rehab
This trial compares core, aerobic, and combined exercise in patients doing phase II cardiac rehab. It aims to find which type works best for heart recovery.
TaipeiAges 18 years+ - NCT07296081Recruiting
PET scan study for heart scarring in heart failure
This study uses a special PET scan to look for scarring (fibrosis) in the heart muscle of people with heart failure. It may help doctors better understand why some hearts get stiff or weak.
Coimbra, Coimbra DistrictAges 18 years+ - NCT06927440Enrolling by invitation
Registry for children with severe heart failure in China
This study is creating a registry to learn more about children with advanced heart failure. It will help doctors understand who can benefit from treatments like medicine, devices, or transplants.
Shanghai, Shanghai MunicipalityAges Up to 18 years - NCT06992089Recruiting
Pacemaker study for heart failure with low heart rate
This trial tests a special pacemaker setting to help your heart beat faster during exercise. It may improve your ability to be active if you have heart failure with preserved ejection fraction (HFpEF) and a low resting heart rate.
ValenciaAges 18 years+ - NCT05562167RecruitingPhase 2
Inorganic nitrate plus exercise for heart failure performance
This Phase 2 study tests whether taking inorganic nitrate can improve exercise ability and heart-function symptoms in people with heart failure with reduced pumping. It also checks whether the treatment is safe when combined with an exercise program.

LOT-CRT vs standard CRT for heart failure with NICD
This study compares a newer pacing therapy (LOT-CRT) to standard cardiac resynchronization therapy (BiVP) for people with heart failure who have a specific type of electrical delay in the heart (NICD). The goal is to see if the newer method works better.
Nanjing, JiangsuAges 18–80 - NCT03895541Recruiting
Test MRI/ultrasound to measure heart stiffness in older heart failure
This study checks whether a noninvasive imaging test can measure how stiff (stiffness) your heart muscle is in older people with certain types of heart failure. It may help doctors better diagnose and sort out the type of heart failure using your scan results.
ParisAges 60–80 - NCT04602338Recruiting
Imaging tests to better diagnose heart failure with preserved function
This trial uses several types of heart imaging to diagnose heart failure where squeezing function is still fairly normal. It may help doctors sort out what’s causing your symptoms and guide better care by comparing imaging findings across many patients.

Imaging tests to find and predict HFpEF risk
This study uses different heart imaging tests to help screen for HFpEF (heart failure with preserved pumping strength), make the diagnosis, and estimate your future risk. You may benefit by getting a clearer diagnosis and a better risk picture based on the scans.
Beijing, Beijing MunicipalityAges Any age - NCT05174351Recruiting
Stopping beta-blockers in heart failure with preserved pumping
This study checks whether safely stopping beta-blocker medicine is possible in some people with heart failure with preserved pumping (EF ≥50%). It may help by testing whether reducing the medication is safe and workable for certain patients.
