“Fewer than half of patients with established atherosclerotic cardiovascular disease currently reach LDL cholesterol goals. An oral therapy this effective has the potential to dramatically improve our ability to prevent heart attacks and strokes on a population level,” said Ann Marie Navar, M.D., Ph.D., a cardiologist and Associate Professor of Internal Medicine and in the Peter O’Donnell Jr. School of Public Health at UT Southwestern Medical Center. Dr. Navar led the study, which was sponsored by the drugmaker Merck & Co. Inc.

Researchers have known for decades that LDL cholesterol causes cardiovascular disease. Cholesterol-containing particles deposit in blood vessel walls, a process called atherosclerosis, which can then cause heart attacks and strokes. Consequently, lowering LDL cholesterol is a cornerstone of preventing cardiovascular disease in people who do not yet have it and reducing the risk of heart attacks and strokes in people who are already affected.
