Barts-MINOCA Registry

This study is building a registry of patients who have had a heart attack but whose coronary arteries — the arteries that supply blood to the heart — appear normal or near-normal on an angiogram. This condition is called MINOCA (Myocardial Infarction with Non-Obstructive Coronary Arteries) and it affects approximately 5–10% of heart attack patients. Because the arteries look normal, MINOCA is often misunderstood and can be underdiagnosed or undertreated. The causes are different from typical heart attacks and can include artery spasm, tiny clots, or inflammation of the heart muscle. By collecting detailed clinical data, imaging, and blood test results from MINOCA patients over time, researchers hope to better understand the underlying causes and outcomes of this condition, leading to better diagnosis and treatment guidelines. You may be eligible if: - You are 16 years old or older - You have received a diagnosis of MINOCA (heart attack without clear obstructive coronary artery disease) - Your cause of elevated troponin (a heart injury marker) is unclear at initial assessment You may NOT be eligible if: - You are under 16 years old Talk to your doctor to see if this trial is right for you.
