Thanks for writing in.
Statins have been shown to prolong survival in patients like you. So theoretically speaking, your life expectancy should be adversely affected if you dont take these drugs. While ever drug has its own side effects, it would be unfair to term them as "poison". Taken in the right dose with appropriate precautions, I believe they are extremely useful. They can cause certain side effects like myopathy
but we need to see the overall risk benefit ratio.
Hope this helps.
