What does the stress test show?
In men with symptoms such as chest pain with activity or unexplained shortness of breath, abnormal stress tests indicate a higher risk of CAD. But it is more concerning in men who also have risk factors such as advanced age, obesity or high cholesterol. "This strongly suggests coronary artery disease." says Additional tests may be required for confirmation.
If you have symptoms and the test results appear normal, your risk of CHD is lower. "These people are less likely to have significant coronary artery disease," says Dr. Sunrinder Khinda however, the doctor may want to do more tests.
But it's important to understand that a "normal" stress test can't rule out the possibility that plaque then ruptures and clogs arteries - the proverbial tale of people who pass stress tests with flying colors and suffer a heart attack a week later - too late. The stress test detects very narrowed arteries (70% or more). This is what causes the symptoms. A heart attack is often the result of a smaller blockage that ruptures and forms a blood clot.
When to do a stress test
The US Preventive Services Task Force, an independent group that makes recommendations to doctors, urged doctors not to offer routine stress tests to people with no symptoms or high risk factors for CAD. Medical groups such as the American College of Cardiology support this recommendation.
