What is a "cardiac stress test"?

A cardiac stress test is a procedure used to see how well the heart works during physical activity. During the test, a person exercises, usually on a treadmill or bike, while their heart rate, blood pressure, and breathing are monitored. The test can help doctors find out if the heart is getting enough blood during exercise, which can reveal problems like blocked arteries or heart disease. The test is often used to evaluate symptoms such as chest pain or to check the heart's health after a heart attack or surgery.
