Hello,
Thanks for writing to Health Care magic, I am Dr , Muhammad Ahmad , I have read your question closely, I understand your concern and will be helping you with your health related problem.
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) Any thing 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.
Dr.Muhammad Ahmad
