Positive Treadmill Stress Test
Having a positive treadmill stress test, how safe is to exercise and at what level can I exercise so as not to cause trouble?
Stress affects most people in some way. Acute (sudden, short-term) stress leads to rapid changes throughout the body. Almost all body systems (the heart and blood vessels, immune system, lungs, digestive system, sensory organs, and brain) gear up to meet perceived danger.

Is it possible for someone with vulnerable (soft) plaques to have a negative treadmill stress test, but still be in danger?
Yes: It's entirely possible - this is, in fact,the explanation for how someone can have a normal stress test and then have a heart attack hours, days, or weeks later: presumably there is no serious blockage at the moment of the stress test, but they rupture a plaque and occlude the vessel at a later time. This is a sad reality. We have no "crystal balls" to predict the future. ...Read more
