As a medical professional with expertise in diagnostic testing, I can provide you with information on stress tests and their capabilities.
A stress test, also known as an exercise stress test, is a non-invasive diagnostic tool used to evaluate how well your heart functions during physical activity. It can help detect abnormalities in heart rhythm, blood flow to the heart muscle, and the heart's capacity to pump blood effectively. The test involves monitoring your heart rate, blood pressure, and electrocardiogram (ECG) while you exercise, typically on a treadmill or a stationary bike.
However, a stress test is not specifically designed to detect blockages. While it can indicate the presence of reduced blood flow to the heart, which could be a sign of blockages, it does not provide a direct visualization of the blockages themselves. To visualize and confirm blockages, other imaging tests such as coronary angiography are used. This procedure involves the use of a catheter to inject a dye into the coronary arteries, which can then be seen on X-ray to identify any narrowing or blockages.
In summary, a stress test can suggest the presence of heart disease, but it does not directly detect blockages. For a more definitive assessment of blockages, additional diagnostic tests are necessary.

"That person is less likely to have significant coronary artery disease," Dr. Bhatt says. ... Stress testing detects arteries that are severely narrowed (70% or more). This is what causes symptoms. Heart attacks often result from lesser blockages that rupture and form clots.
