This is a research registry—a long-term tracking study—for people who experience chest pain, discomfort, or shortness of breath but don't have the typical blocked arteries that doctors usually find in heart disease. Researchers want to understand what's actually causing your symptoms and how your condition changes over the years. You'll have specialized heart imaging tests done as part of your regular medical care, and that information will be added to a research database to help scientists learn more.
Many people have chest pain and symptoms that feel like a heart attack, but their angiograms (detailed heart imaging) show no blockages. Doctors don't yet fully understand what causes these symptoms in this group or how to best treat them. This study aims to identify the real underlying problems and track how patients fare over many years.

You will undergo specialized heart imaging tests (angiography, ultrasound, and physiology testing) as part of your standard medical care. After that, researchers will contact you periodically by email or phone—at 6 months, 1 year, 3 years, 5 years, 10 years, and every 5 years afterward—to check on your symptoms, health history, and overall status through surveys and brief check-ins. The study can continue for 10+ years, but you're in control of how much you participate in the follow-up contacts.
