Dual Imaging Identifies Cause of Heart Attack in Patients Without Blocked Arteries
The study found that advanced coronary OCT and cardiac MRI imaging identified causes in 79% of MINOCA cases, improving diagnosis and guiding treatment decisions.
- On Saturday, March 28, 2026, researchers led by NYU Langone Health announced that combining coronary optical coherence tomography and cardiac MRI identified the cause of heart events in 79 percent of patients with myocardial infarction with non-obstructive coronary arteries .
- MINOCA accounts for 6 to 15 percent of heart attacks, yet standard angiograms often fail to identify artery wall damage or other underlying causes, leaving patients without clear diagnoses.
- Ashley Perlow, a 36-year-old mother from New Hampshire, struggled for months after standard tests showed normal arteries, calling the condition a "scary type of heart attack" due to diagnostic uncertainty.
- Dr. Harmony R. Reynolds of the Cardiovascular Clinical Research Center noted that comprehensive imaging is often necessary to get the full answer, as clinicians cannot reliably predict which patients benefit from specific tests.
- The study enrolled 336 patients across 28 international sites, and future research will focus on developing treatment strategies tailored to the specific causes identified through these imaging methods.
