Statins, medications to lower cholesterol, used by over 200 million people across the world, might not do much to lower the risk of a heart attack or stroke. According to a new study published in the journal JAMA Internal Medicine, researchers at the Royal College of Surgeons in Ireland found statins had an “inconsistent and inconclusive impact” on cardiovascular disease outcomes. They believe that the benefits from lowering LDL cholesterol using statin drugs might be specific to each person based on other risk factors. It’s important to talk to your doctor about statins and other treatments to lower your risk of heart disease.
