This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
Researchers want to know if a cardiopulmonary exercise test (a specialized test where you exercise on a stationary bike while your breathing and heart function are measured) can reliably detect when the heart isn't getting enough blood flow. This study will compare the results of this exercise test with a detailed heart imaging scan (PET/CT) to see if they match, and whether the exercise test can also track whether blood flow to the heart improves after treatment.
Currently, doctors use expensive heart imaging to diagnose reduced blood flow to the heart. If the exercise test proves accurate, it could offer a simpler, more accessible way to both diagnose this condition and monitor whether treatment is working.

You will first have a heart imaging scan (PET/CT) as part of your regular care. A few days later, you will come back to exercise on a stationary bike in a controlled setting while doctors measure your heart rate, blood pressure, and oxygen use. If you later receive heart treatment (such as surgery or a catheter procedure), you'll be invited to repeat both the exercise test and imaging scan six months afterward to see if your heart's blood flow has improved.
