I am 37 year old male. I had a clean chit from angiography just a year ago. I had gone due to low intensity, but continued chest pain. I do not have diabetes, do not smoke, or drink. However, I am over-weight, and have had slightly elevanted level of LDL and trigycerides (only for the last six months). My query is, what are the chances of getting blockage right within one year of a all clear angiography?
