About A Year Ago I Had A Stent Placed In

About a year ago I had a stent placed in my artery and as a result am on the baby aspirin, Lipitor, Plavix and a beta blocker (atenolol). I was formerly taking Coreg and had ED as a result... Now I take the Atenolol and the ED is gone but Tinnitus is awful.... I am not sure what I can take!!! All of this is driving my crazy!
