IS THERE ANY INSTRUMENT/ MACHINE FOR KNOWING % BLOCKAGE IN HEART VEINS?

Hi Pawan,
Yes.
An angiogram, or heart catheterization, is the most common. Basically, they inject a contrast solution into the vessels and monitor the flow via a CT scan.
It is fairly safe.

I don't know about vein blockage but I had 6 arteries with blockage that had to be bypassed. The blockage is cholesterol that builds up on the wall of the artery making the flow slower. They consider fixing any that are over 50% blocked. At least that was the cutoff point when I had mine done 25 years ago.
