Heart muscle coordination and microvessel function SPECT study
This study uses a special heart scan (SPECT) to look at how well the heart muscle is squeezing and how well the tiny blood vessels in the heart are working. It may help doctors understand why some people have chest pain even when their main arteries are not blocked.
TomskAges 18–75 - NCT05426408Recruiting
Test study for heart attacks without blocked arteries
This study looks at people who may have MINOCA (heart attack symptoms with no major artery blockage) or takotsubo syndrome (a temporary stress-related heart condition). The goal is to better understand these causes and how they should be diagnosed and treated.
StockholmAges 35–79 - NCT07646977Recruiting
Blood Clot Treatment for Heart Attack Recovery
This trial tests a new approach to treating blood clots during a heart attack to prevent damage to the small blood vessels in your heart. You would receive this treatment during an emergency catheterization procedure if you have signs of a major heart attack.
OdenseAges 18 years+ - NCT04612322Recruiting
Study registry for microvascular angina patients
This registry study collects information from adults with microvascular angina (chest pain from small blood vessels in the heart). It may help researchers better understand how to assess and manage this condition over time.
Mainz, RLPAges 18–85 - NCT04822649Recruiting
Assessing exercise capacity in people with heart microvascular problems
This study looks at how well you can exercise and how your body composition relates to tiny blood-vessel problems in the heart. It may help doctors better understand symptoms and function in people who don’t have major blockages in the large heart arteries.
SeoulAges 20–80 - NCT06376630Recruiting
Esmolol for heart protection during heart attack
This study tests if giving a fast-acting heart medication (esmolol) early through an IV can protect the heart muscle during a heart attack. It may help patients who cannot receive a standard treatment due to certain risks.
MoscowAges 18 years+ - NCT06588244Recruiting
Registry for chest pain with open arteries
This study is looking at people who have chest pain or shortness of breath but whose heart arteries look fairly open on an angiogram. It aims to understand why they have symptoms and how to improve care. You may qualify if you're having a coronary angiogram and it shows no major blockages.
Naples, ItalyAges Any age - NCT07293338Recruiting
Heart muscle blood flow study for dilated cardiomyopathy
This study looks at how small blood vessels in the heart affect outcomes in people with dilated cardiomyopathy (an enlarged, weak heart). You may qualify if you have heart failure with a weak pump and no significant blockages in your main heart arteries.
Hangzhou, ZhejiangAges 18 years+ - NCT07380919RecruitingPhase 2/Phase 3
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.
