My doctor wants me to do a stress test; however, I am unable to walk on the treadmill, because I have a bum knee. He said he can do a test with chemicals instead, but that sounds dangerous. He says it is safe, but is that true?
Cardiologists use certain chemicals that basically simulate exercise in order to perform stress tests to look for blockages in the heart arteries. Some of these chemicals raise the heart rate to mimic exercise, and others just dilate (or open) the arteries a little extra to see how the heart performs under stress.You may feel flushed.  Also your heart will race, you may develop a headache, or even a little chest pain during these tests. Since you are closely monitored, they are very safe.
