Faster troponin test for chest pain in the ER

Steroid to protect kidneys during heart surgery
This trial is testing whether a single dose of the steroid methylprednisolone, given before heart surgery, can protect your kidneys from damage during the operation. If you qualify, you'll receive the drug or a placebo, and your kidney function will be monitored closely.

Arm cuff treatment before surgery to protect lungs in older adults
This study tests if a simple, non-invasive treatment (briefly inflating a blood pressure cuff on your arm) before surgery can reduce lung complications in older adults having non-heart, non-lung surgery. It may help protect your lungs during and after the operation.
ShanghaiAges 65 years+ - NCT07197918Recruiting
Finding brain injury with a portable MRI after cardiac arrest
This study uses a portable MRI machine to look for brain injury in people who remain unconscious after their heartbeat is restored (ROSC) from a cardiac arrest. If you are having a standard MRI and being treated with temperature control, you may be eligible.
New Haven, ConnecticutAges 18 years+ - NCT07201363Recruiting
Inflammation and scarring markers after TAVI
This study looks at markers of inflammation and scarring in people who develop heart rhythm problems after having a TAVI procedure (a minimally invasive valve replacement). It may help doctors understand and predict these complications.
Rijeka, CroatiaAges 18 years+ - NCT07202247RecruitingPhase 2
Improving heart health in prostate cancer patients on hormone therapy
This study tests whether combining a time-restricted eating plan, a heart-healthy diet, and a weight-loss medication (GLP-1 receptor agonist) can help improve heart health and weight in men with prostate cancer who are receiving hormone therapy. It aims to reduce the risk of heart problems caused by hormone treatment.
Duarte, CaliforniaAges 30–79 - NCT06207942Recruiting
Extended follow-up for cardiac arrest survivors and caregivers
This study follows up on survivors of out-of-hospital cardiac arrest who were already in the STEPCARE trial. It also looks at the well-being of their main caregiver (like a family member or close friend) to see how everyone is doing over time.
BrisbaneAges 18 years+ - NCT06670768Recruiting
Comparing two heart imaging tests for blocked arteries
This trial compares two heart imaging tests (SPECT and coronary CTA) to see if a newer method gives a clearer picture of blood flow. If you have been referred for one of these tests, you may be able to help by also having the other test done at no extra risk.
Budapest, BudapestAges 18 years+ - NCT06817239Recruiting
Low-dose esketamine for preventing confusion after surgery in older adults
This study tests whether a low dose of the medicine esketamine can help prevent confusion after surgery in older adults at higher risk. You may qualify if you are 65 or older, planning a major non-cardiac surgery, and have certain health conditions like high blood pressure or diabetes.
Fuzhou, FujianAges 65–90 - NCT07184476Recruiting
Measuring small blood vessels in kids having heart surgery
This study looks at tiny blood vessels in children with specific heart defects during surgery. It may help doctors better understand circulation and improve care.
Boston, MassachusettsAges 1 day–17 years - NCT07179029Recruiting
Can anesthesia affect the heart during non-cardiac surgery?
This study looks at whether anesthesia can cause heart damage during non-cardiac surgeries. If you have certain health risks, participating may help doctors learn how to better protect your heart.
TübingenAges 40–80 - NCT07182175Enrolling by invitation
Heart health during adrenal tumor surgery study
This study looks at how different types of adrenal tumors might affect the heart during and after surgery. It aims to help doctors understand and reduce the risk of heart injury in patients having these tumors removed.
BeijingAges 18 years+ - NCT07179991Recruiting
DDAVP (desmopressin) for bleeding during heart surgery
This study tests whether a medicine called desmopressin (DDAVP) can reduce bleeding during heart surgery. It uses a special blood test (TEG6) to decide who gets the medicine.
London, OntarioAges 18 years+ - NCT07176286RecruitingPhase 2
PET scan study for diagnosing Lewy body dementia
This trial is testing a special PET scan that uses a radioactive tracer (18F-mFBG) to see how much it is taken up by the heart. The goal is to help tell Lewy body disease (Parkinson's or Lewy body dementia) apart from other brain disorders.
Houston, TexasAges 18 years+ - NCT07174206Recruiting
Smartwatch monitoring for heart patients

Common questions
- Are there clinical trials for cardiac?
- Yes. Clin2 currently lists 1,291 recruiting cardiac studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a cardiac trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a cardiac trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
