Kates.Sorry to hear of you recent heart problems.I do not have the extensive problem you have. I have a life time A-iFb and did not think much of it. My family physician suggest a blood thinner. I got warferin and was tested for levels on a periodic basis. But as I aged, now 90 years old, the use of a pace maker was suggested, My energy really increased after 60 demand St. Jude implant. It was simple and I don,t know it is there. This was done as a preventative of throwing a clot for a stroke. I had to switch to Eliquist blood thinner when warferin did not keep me in the groove. It works well for me two times a day. My reason to encourage is in exercise. I am a retired Physical Therapist. I have lots of spinal problems and need a walker. But,the story is, do not blame any heart problem on exercise. I exercise daily, take my walker to the mall to walk in the winter and am now finishing the first of the year physical Therapy referral. I hang inverted 2 times a week at 45 degrees. I will continue at $35. a month at a new spa. In addition, part of the treatment is seeing other people and chatting.My daughter graduated from Akron U. with a BA in Choreography. I know how much control and grace you struggled for as a Dancer. Your heart is stronger with your problem now then if you had not laid the background to live longer. I am a health nut. Google berries, nuts, honey with garlic, Himalayan pink salt satuation for hydrartion, apple cider vineager in organs and and intestinal tract, flaxseed oil and cottge cheese, steaming normal food and vegetables,. etc. & family me,bers died of cancer. Make a decision that now is the time to lower your blood pressure with good eating habits,( not diets), exercise, social contact the freedom from stressors. Stressors can be bad food, bad people, bad thoughts. Job, Solomon lived to be 140.yrs old Why can't I? Why am I not dead like the rest of my family? Execising, old style eating habit, not smoking, minimal alcohol, getting away by your self and being positive are part of the answer. I am sure other good people will come forward with excellent advice. Now is the time to listen to them. Good Luck! bill54321
