You really should pick one diagnosis and stick with it. You do NOT have cancer or EF or ALS or IBS or any other symptom except perhaps NARCISISM and Munchausen. Get psychiatric help and stop pushing your imaginary symptoms off on innocent people sympathy you homely cat freak.
Sorry to hear of your circumstances. According to your post there is a decrease in heart wall motion (contractions) and as a result the amount of blood pumped with each beat is 40% s/b 55 to 75%.
Shortness of breath, chest pain, fatigue are symptoms of a lower cardiac output. You should, as you are doing, see cardiologist to diagnose the underlying reason. It can be a prior heart attack (sometimes "silent" [without symptoms] happened to me) congenital, drugs, medication, alcohol, or viral, etc. and successfully treated.
You should see a doctor quickly as chest pain (angina) can sometimes seriously damage heart cells and further decrease wall motion..
Hi i had a virus attack my heart at 27 and mine EF was at 25% . Now 7months later its back up to 45% with medicine and diet. I go to the cleveland clinic and there awesome there. I also just started taking COQ10 it's for the heart and i have the GNC kind but research it and only take pills that get approved on consumerlabs.com. Just wait and see the doctor and just take it easy until then, 40% is below the normal 55% but its not that bad. Hope that helped.
I forgot to include, and don't know if it matters. I am 5'0, 100 lbs, low blood pressure, no diabetes, mostly vegetarian diet.
