i understand your anxieties.
The prognosis in sch a case will depend upon the presence pumping ability of your heart (ejection fraction
), the extent of disease in other arteries/vessels and your present functional capacity. Needless to say higher the ejection fraction, lesser the involvement of other vessels and better the functional capacity, better will be the overall survival and prognosis. For the sake of numbers, in one of the studies, survival at 5 years in single vessel disease
with blockade of LAD>95% was 83% but mind it , it is an old study, when drugs were not so good as today and moreover the data applies to a group of people and not individuals.
Best way is to talk to your cardiologist, get guidelines based treatment and adopt a healthy life style. do not worry much about prognosis because there are so many things unknown to medical science and so many known things which can not be modified.
