Same is a case with you. You can consult a cardiologist as advised and if a stress test is required, a dobutamine stress test can be performed using infusion of a Chat Doctor.  In this test you don't have to walk on a treadmill. Alternatively your cardiologist can examine you and have a word with the surgeon or anesthetist. Of course you will have to sign a high risk consent showing that you understand the risk posed by cardiac disease or risk factors if present. </s>
