Recovering from a stent opearation that probably prevented a major heart attack...

A little worried that all these meds are having side effect that may harm me in other ways...

I have changed my diet radically and am avoiding animal fat, sugar and salt totally....

I have replaced animal fat/protein with vegetable protein.

Loosing weight is a plus but still feel weak and the constant pinching feeling in my left lower chest area is bothering and worrying me.

Has anyone heart explanations from their doctor or has a link to a journal article on this?
