People who have coronary artery disease, stroke or peripheral artery disease often are prescribed a statin, a cholesterol-lowering drug that reduces the risk of heart attack or stroke.In a recent publication in JAMA Network Open, Mayo Clinic researchers identify trends in statin use across the U.S. among people with these diseases, as well as among those who already had a stroke or transient ischemic attack (TIA). Their data indicate that only about 60% of patients are getting the recommended therapy.
