My Cardiologist says that I need to wait for Physical therapy because I had so much heart damage. It has been a month since he has said that and now he wants me to wait another month. I am 58 years old diagnosed with heart failure . I have had no new tests since the stents have been put in. My question is , What is the reasoning behind not doing any exercise from a cardiologist stand point? I was under the assumption exercise was essential for recovery.
