Best of luck to you when your time comes up.Well I'm still in the waiting room..? But as far as I can' tell from most studies as long as your not experiencing any symptoms your survival rate is pretty good. Its when you start experiencing symptoms that the death rate shoots up to 2% a month.
In the past doctors, unfortunately, preferred to wait. Every time I asked a cardiologist to recommend surgery while I was fit and strong...they all had same answer: “avoid the knife as long as you can”! I’m glad this is no longer applicable, as yes one has better chance when one‘s heart and health are better.
