Who could benefit from this research

Could help

Adults with persistent chest pain after COVID-19 who have well-characterized medical histories and can undergo MRI.

Less likely to help

Patients without persistent chest pain or those unable to undergo MRI would be less likely to benefit.

What this research studies

This project uses a rapid, free-breathing MRI test to measure how well the heart’s small vessels are working in patients with long COVID. The goal is to identify a reliable imaging approach that can guide therapy without exposing patients to radiation. It focuses on people with persistent chest pain after COVID-19 and uses comprehensive MRI measures to assess blood flow, tissue health, and scar. The study builds on existing MRI techniques already used in clinics and applies them specifically to long COVID patients.

Why it matters

Potential benefit: If successful, the imaging test could help doctors diagnose microvascular issues in long COVID and tailor treatments more precisely.

How similar studies have gone: Previous work supports using cardiovascular MRI to assess microvascular function, but this study applies it specifically to long COVID with chest pain.
