Hi,
I would need more details about your case to satisfactorily answer your question.
1. What is your age and sex?
2. What was the problem to begin with and how long back did it start?
3. Do other people in your family have similar problems like your parents or brothers?
4. Is your weight near the ideal weight for your height and age?
It could be possible that you could be having
Metabolic syndrome which predisposes to
Atherosclerosis and plaques in the arteries. Is your
Lipid profile normal?
Secondly, putting four stents and then another four is usually not undertaken and bypass is usually preferable but it would be incorrect to advice until I see all your reports.
Do let us know how I can help you better.
