This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing whether two types of heart monitoring—one done during a standard procedure called coronary function testing, and one done at home—can help doctors better diagnose why some patients have chest pain even though their heart arteries are not blocked. About 40-70% of people diagnosed with angina (chest pain) don't actually have blocked arteries, yet they continue to suffer from chest pain and reduced quality of life. This study aims to find patterns in how the heart's blood vessels behave during these symptoms.
Many patients experience ongoing chest pain even after doctors confirm their coronary arteries are not blocked—a condition called ANOCA. Currently, diagnosing the real cause requires an invasive procedure, and doctors sometimes miss the subtle warning signs on the heart's electrical recordings. This trial exists to develop better, more accurate ways to identify the underlying problem so patients can get appropriate treatment earlier.

If you join, you will undergo coronary function testing (an invasive procedure where doctors place a thin wire in your heart artery and perform special tests to see how your blood vessels respond). During this procedure, doctors will use advanced heart monitoring to record electrical signals from your heart more carefully than usual. After your procedure, you will also wear a portable heart monitor (Holter monitor) at home to track any heart rhythm changes during your normal daily activities and symptoms.
