Stress cardiac MRI reclassified 53% of chest pain patients, especially women, improving diagnosis and treatment.
A new study presented at the 2025 American Heart Association Scientific Sessions found that stress cardiac MRI improved angina diagnosis and treatment for adults with chest pain but no blocked arteries.
Among 250 participants, 53% were reclassified, mostly to microvascular angina—often missed by standard tests—especially in women.
Those guided by MRI results had significantly better symptom relief and quality of life at 12 months and were more likely to receive effective medications.
The findings suggest stress CMR can uncover treatable causes of chest pain overlooked by angiography, offering a more accurate path to care.
