I am a 65 y/o Black female without any heart attack risks, no HBP , Diabetes, obesity , family hx. I had a mild MI 9/2013 with stent . Prior to this I took no medications. Recent creatinine level 1.40, medications are aspirin 325, lisinopril 2.5mg, clopidogrel 75mg, simvastatin 20mg. Now PCP wants repeat blood work. Can level increase be due to medications ?
