Predicting heart rhythm problems after heart surgery
This trial studies whether measuring how the upper chambers of the heart work together can help predict dangerous heart rhythms after heart surgery. If you are in normal heart rhythm and not having mitral valve surgery, this study may help doctors better prevent complications.

Study of ranolazine to prevent heart muscle damage after a heart attack
This trial tests whether a medication called ranolazine can help prevent damage to tiny blood vessels in the heart after a certain type of heart attack (STEMI). You may be eligible if you recently had this kind of heart attack and had a successful procedure to open a blocked artery, but still have other blockages that can be treated with stents.

Using the ulnar artery for heart tests when the radial artery is blocked
This trial looks at using the ulnar artery in the wrist instead of the radial artery for heart catheterization or stent placement, when the radial artery on that side is blocked. It may be an option for people who cannot use the other arm's radial artery.
AthensAges 18 years+ - NCT07380217Recruiting
Using heart pump support for complex high-risk procedures
This trial is testing whether using a special heart pump (PulseCath iVAC2L) during complex, high-risk angioplasty can help people with very weak hearts. It's for people who need a procedure for complicated coronary artery blockages.

Screening for brain aneurysms in high-risk family members
This study uses a special MRI scan to look for unruptured brain aneurysms in people who have a close family member who had a bleeding aneurysm. It aims to find aneurysms early in those who smoke or have high blood pressure.
Novi Sad, VojvodinaAges 18 years+ - NCT07381816Enrolling by invitation
Study of gut blood flow in people with post-meal low blood pressure
This study uses MRI to measure blood flow in the gut when you eat, to understand why some people get dizzy or lightheaded after meals. It compares people with postprandial hypotension to healthy volunteers.
Glostrup MunicipalityAges 18–90 - NCT07386418Recruiting
Angina thresholds study for patients needing stent treatment
This trial is testing a new way to measure blood flow in the heart during exercise to better understand angina. You may be eligible if you have at least two blocked heart arteries and are scheduled for stent placement.
BasildonAges 18 years+ - NCT07382739RecruitingPhase 2
Radiation and immunotherapy for advanced multiple myeloma
This trial tests whether combining radiation therapy with the drug elranatamab can help people with multiple myeloma that has come back or not responded to treatment, especially when the cancer has spread to soft tissues or bones outside the bone marrow. The goal is to see if this combination can make the immune system fight the cancer more effectively.

HaifaAges 18 years+ - NCT07388342Recruiting
CT heart scan after cardiac arrest without heart attack
This trial tests whether a special CT scan of the heart can help doctors see blockages in people who survived a cardiac arrest but did not have a typical heart attack. If you qualify, the CT scan might provide important information without needing a standard heart catheterization first.
Brussels, Vlaams BrabantAges 18 years+ - NCT07384871Recruiting
