Recruiting studies
- NCT04347200Recruiting
Long-term blood-thinner therapy registry for heart disease
This study follows people with known coronary artery disease to understand how long-term “blood thinner” treatments are used and how they affect health over time. You may be asked to share medical information and come in for follow-up to help researchers compare outcomes.
MoscowAges 18 years+ - NCT04347187Recruiting
Long-term blood-thinner study for atrial fibrillation patients
This trial follows people with atrial fibrillation to see how long-term blood-thinning treatment affects outcomes over time. It may help determine which long-term approach best lowers stroke and clot risks for patients like you.
MoscowAges 18 years+ - NCT04666454RecruitingPhase 4
Medication trial for broken heart (Takotsubo) syndrome
This trial tests an optimized medication approach for people diagnosed with Takotsubo (“broken heart”) syndrome. It may help clinicians find a safer and more effective treatment plan after this heart condition.
AarhusAges 18 years+ - NCT04800913Recruiting
Imaging tests during left atrial appendage closure
This study looks at how different imaging tests can help guide a procedure that closes off the left atrial appendage to reduce stroke risk. It may help doctors choose the safest approach during the procedure.
BudapestAges 18 years+ - NCT04906356Recruiting
Study of SCAD after a heart attack or unstable chest pain
This study looks at people admitted with a recent heart event (STEMI, NSTEMI, or unstable angina) and who were found to have SCAD on a heart scan. It may help doctors better understand and manage SCAD after these urgent events.
Vancouver, British ColumbiaAges 18 years+ - NCT04976348Recruiting
Heart monitoring registry for teens and adults with heart symptoms
This study registers people who are referred to cardiology or genetics for heart-failure–type symptoms or heart/cardiogenetic screening. It helps doctors understand how monitoring platforms may support diagnosis and follow-up.
Maastricht, LimburgAges 16 years+ - NCT05293366Recruiting
Long COVID study testing supportive care for multiple body systems
This study looks at people who have recovered from COVID-19 but still deal with long-term problems. It aims to better understand (and potentially help with) ongoing issues that can affect hormones, metabolism, mood, muscles, the heart, lungs, and skin.
NaplesAges 18 years+ - NCT05660811RecruitingPhase 4
Antiplatelet medicines after left atrial closure in dialysis patients
This trial looks at the best blood-thinning (antiplatelet) plan after a left atrial appendage closure procedure in people with kidney failure on dialysis. It may help reduce stroke risk while also lowering medicine-related side effects.
Warsaw, Masovian VoivodeshipAges 18 years+ - NCT05660798Recruiting
Switching from cigarettes to heat-not-burn to protect heart arteries
This study looks at whether switching from regular cigarettes to a tobacco heating product slows buildup of plaque in the heart arteries. You’d be guided through smoking change and monitored using heart scans, to see if artery plaque stays the same or improves.
WarsawAges 18–75 - NCT05800821Recruiting
Predicting brain blood-flow problems after carotid surgery
This study uses deep learning to predict which people are at risk for “cerebral hyperperfusion syndrome” (a dangerous spike in brain blood flow) after carotid revascularization. If you qualify, they’ll use scans/tests to estimate your risk so doctors can watch you more closely if needed.
MinskAges 30–80 - NCT05859048Recruiting
Care plan to help high-risk people spot heart failure early
This trial tests a multidisciplinary care approach aimed at helping people with high risk for heart failure get diagnosed earlier. It may help you catch heart failure sooner if it starts, so treatment can begin earlier.
Vancouver, British ColumbiaAges 40 years+ - NCT05903001Recruiting
Breathing muscle testing to help track lung disease
This study checks whether measurements of your breathing muscle (the diaphragm) can act as a useful “biomarker” to track lung disease. You might be asked to do breathing tests and follow study instructions, and your results may help researchers better monitor COPD, asthma, fibrosis, or pulmonary hypertension.
Aachen, North Rhine-WestphaliaAges 18 years+ - NCT05916898Recruiting
Shockwave treatment after difficult stent expansion
This registry studies how well shockwave therapy works when a previously placed heart stent does not expand well, especially when the artery is quite calcified. Your care team would use it after other tools to prepare the blockage have not worked.
Legnica, Lower Silesian VoivodeshipAges 18–99 - NCT05987410Recruiting
Nordic walking for weight and heart health after a cardiac event
This trial tests if a nordic walking program helps people with diabetes who are overweight or obese recover after a heart attack or heart procedure. If you had a heart event or stent/bypass in the last 3 months, this program could help you get stronger and manage your weight.
MilanAges 18 years+ - NCT06090591Recruiting
Heart condition research registry at Dubrava Hospital
This study is a registry that will collect information from people with certain heart conditions (like having a pacemaker, a blood clot, a heart attack, or a valve replacement procedure called TAVI). The goal is to learn more about these conditions and how they are treated.
ZagrebAges 18 years+ - NCT06156670Recruiting
A study of closing a PFO to prevent strokes
This trial looks at the safety and results of closing a PFO (a small hole in the heart) in people who have had a stroke or embolism with no other clear cause. If you qualify, doctors will close your PFO using a small tube inserted through a blood vessel and then follow your health over time.
MoscowAges 18–70 - NCT06169241RecruitingEarly Phase 1
Nitrate supplement for resistant hypertension
This trial tests whether a natural nitrate supplement (like beetroot juice) can help lower blood pressure and improve blood vessel function in people with resistant hypertension. If you have resistant hypertension and your medications have been stable for at least 30 days, you may be eligible.
Rio de JaneiroAges 18–75 - NCT06275386Recruiting
Drug-coated balloon for chronic heart artery blockages
This trial tests whether a special balloon coated with medicine (drug-coated balloon) can safely open a completely blocked heart artery, instead of using a permanent stent. It may be an option for people who have chronic chest pain or shortness of breath due to a long-standing blockage.
Warsaw, Masovian VoivodeshipAges 18 years+ - NCT06284057Recruiting
Culotte stent technique study for Y-shaped heart blockages
This trial studies two different ways of placing stents in Y-shaped blockages in the heart's arteries. It aims to find which technique works best for people who need two stents in that area.
Legnica, Lower Silesian VoivodeshipAges 18 years+ - NCT06288165Recruiting
Sinus reducer trial for persistent chest pain
This study tests a device called the sinus reducer for people with long-lasting chest pain that hasn't improved with medication or other procedures. It may help if you have limited options for treatment.
Lubin, Lower Silesian VoivodeshipAges 18 years+ - NCT06331819Recruiting
