This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
Researchers are trying to understand why some patients experience chest pain or shortness of breath even though their heart's main pumping chambers work normally. This study will use specialized heart imaging and exercise testing to see how blood flow in the heart's smallest vessels and a person's body composition (muscle, fat, and bone) relate to their ability to exercise.
Many people have heart symptoms but normal results on standard heart tests, leaving them and their doctors unsure what's causing the problem. This research aims to find new ways to diagnose and understand these cases so patients can get better answers and more targeted treatment.

You will visit the hospital for testing that includes body composition analysis (like a scan to measure muscle and fat), heart imaging with medication (adenosine stress echocardiography) to see how your heart's small blood vessels respond, and an exercise stress test on a treadmill or bike to measure your maximum oxygen intake. These tests help researchers understand the connection between your heart's tiny blood vessels, your body composition, and your exercise ability.
