While many Americans take statins to protect their heart health, a JAMA Viewpoint article published today by a UMass Medical School nationally recognized geriatrics expert and researchers with Kaiser Permanente addresses the need to develop a better understanding of the long-term benefits and risks for the millions of older Americans who are taking statins to prevent heart attacks and strokes.

"Though statins can be effective in preventing heart disease, we need to pay attention to the increasing numbers of people who are prescribed these drugs in late life," said Jerry Gurwitz, MD, the Dr. John Meyers Professor of Primary Care Medicine and professor of medicine and family medicine and community health. "While compelling evidence supports statins for secondary prevention in individuals over 75 years of age with clinical atherosclerotic cardiovascular disease, information on the benefits and risks of statin therapy for primary prevention in this population is extremely limited." 

Dr. Gurwitz, Stephen Fortmann, MD, senior investigator at the Kaiser Permanente Center for Health Research, and Alan Go, MD, chief of cardiovascular and metabolic conditions research at the Kaiser Permanente Northern California Division of Research, co-authored the article in a special edition of JAMA on statins. 

The authors point to a risk calculator tool recommended by the American College of Cardiology and American Heart Association in 2013 for predicting a person's chance of experiencing cardiovascular problems.  In a 2016 study, Dr. Go and collaborators at Kaiser Division of Research studied more than 307,000 middle-aged men and women of various ethnic groups who did not have a history of diabetes, previous heart problems or were not taking cholesterol lowering drugs. They compared how well the calculator predicted their risk of a life-threatening heart event.  "The calculator overestimated the risk of heart problems up to five and six times," Go said. "That means that many people prescribed statins may not necessarily benefit from taking them, suggesting that the risk calculator may not be the best tool to use in making decisions about treatment," Go said.

According to Gurwitz, the risk calculator suggests that every person above age 75-79 should be taking statins, regardless of other risk factors for heart disease. 

"We need to conduct a trial of statins in older patients without heart disease to finally understand the balance between benefits and risks," Dr. Fortmann said.
