There is nothing like chelation therapy
. There are drugs known as Statins that control your cholesterol. If your bad cholesterol is high, we need to start you on statins or if you are already taking it, increase its dose.
Well statins may or may not open up your arteries . There are some reports of fact that it may reverse you atherosclerosis
but it is rare. What it can do is prevent worsening of the atherosclerosis in your arteries. if the plaque
in your arteries are calcified, chance of it being reversed by statins alone are very very rare.
I would recommend you to follow you doctors advice as given .
With Warm Regards
