You havent mentioned your age and also not mentioned how long you are on tablets for cholesterol
You have mentioned you have good cholesterol and sugar control with Good RFT & LFT reports
Treadmill test indicates inducible ischaemia at 98% for target heart rate
in cardiac stress ananlysis.
This suggest that there is a possibility of blockages in the arteries that supply blood to heart.
But this stress test
has a minimal chance of giving false positive result ie it may say you are having problem when you actually dont have one.
Always the next step for this kind of report is getting an angio done.
Since most of the cardiac conditions are silent till it is out of hand. It is better getting angio done soon
