My husband had a mild heart attack three years ago, at aged 39. Since then, he has been on a variety of standard medications - including high blood pressure meds - and has had 12 stents placed over four procedures. His last two routine lab tests showed an elevated microalbumin (300) and slightly high fasting blood glucose (103-105). An ultrasound of his kidneys revealed small cysts, but he shows no signs of kidney failure or inherited disease, and all of his other blood work is normal. Could his meds be causing these kidney issues?
