### input:
I was diagnosed with CHF caused by a Dr. giving me 2 bags I.V. wide open while I was in A.Fib and sent me home. 2hrs. later my wife has me in e.r. in chf. 1 day in icu, 4 more days in hospital. This was this past June 18. Have been on heavy meds., now cut back some and have had no recurring problems except stamina is very weak. No congestion at all, but how can I regain my stamina. All that i.v. went straight to my lungs. Took 5 hours of Lasix i.v. to ge it off. No more problems except stamina lost. been very little physical activity for 7 months.

Hello, Thanks for writing to Chat Doctor, I am Chat Doctor. Here in your case stamina loss is because of two reasons.1) Compromised heart activity.2) Prolonged period of reduced activity. You know quite much about your disease, so I will hereby tell you a simple principle which will help your recovery in some way or the other.1) Your heart is compromised to some extent, so you can't be active like a normal person.2) You can only put that much pressure on your heart which it can bear.3) Anything which increases heart rate puts pressure on heart, it can be fear, stress, anger, fever, pain, exercise, exertion or anything. You can't avoid all these, but you have to keep it within the limit your heart can bear. In short, you can live a normal life till you aren't putting your heart under more stress than it can bear. I would suggest you to visit any cardiac rehabilitation center, they will guide you through your journey of recovery, about food about exercise, this will be a gradual process, but you can gradually get much better, and can live normal or near normal life. I hope this answered your question, If you have more queries I am happy to answer you. Regards.
