As a cardiovascular specialist, I can explain that a positive stress test indicates that there is some form of abnormality detected during the test that suggests potential heart problems. Here's a breakdown of what each point could mean:
1. Changes in the electrocardiogram (ECG) show a low oxygen supply to the heart muscle; this could mean that there is a blockage or narrowing in the coronary arteries that supply blood to the heart.
2. If you develop trouble breathing or chest pain during the test, it could be a sign of angina, which is chest pain due to insufficient oxygen supply to the heart muscle.
3. Your heart rate, blood pressure, or both fails to increase adequately during exercise; this could indicate that the heart is not responding normally to the increased demand for blood flow during physical activity.
4. The results of a nuclear stress test show areas of your heart are not receiving enough oxygen during exercise; this is a more detailed type of stress test that uses imaging to visualize blood flow to the heart muscle and can identify specific areas that are not getting enough blood supply.
