What does it mean if my stress test is negative?

Your heart's OK!: It means you did not show signs of heart trouble with exercise ("stressing the heart"), and is generally a sign that your heart function is normal, which it should be at age 34.

Good news...: Numerous studies have found the rate of cardiac events after a negative radionuclide stress test to be less than 1% per year.

No Ischemia: A stress test is a test designed to detect the presence of myocardial ischemia. Ischemia occurs when there are blockages in the arteries. These limit the amount of blood that can get to the heart muscle. When you exercise that muscle needs more blood, if it can not get adequate blood it becomes ischemic and this is what stress tests are designed to detect.A negative test means no ischemia detected.

"negative" is good: A "negative" stress test means the absence of what is being tested for--i.e. No signs of flow-limiting blockages in coronary arteries. In other words, the heart muscle is getting plenty of blood flow. It's important to note that a normal stress test does not mean the absence of underlying non-obstructive coronary disease. Detecting this may require other tests, depending on your risk profile.
