Marc S. Sabatine, MD, MPH is the Chairman of the Thrombolysis in Myocardial Infarction (TIMI) Study Group, an Associate Physician in Cardiovascular Medicine at Brigham and Women’s Hospital (BWH), and an Associate Professor of Medicine at Harvard Medical School. After completing his medical degree at Harvard Medical School, Dr. Sabatine undertook a clinical fellowship in cardiovascular disease at Massachusetts General Hospital and a fellowship in cardiovascular research at BWH. His clinical interest is in acute coronary syndromes and critical care, and his research interests include coronary artery disease, acute coronary syndromes, dyslipidaemias, proteomics and genomics. As chairman of the TIMI Study Group—an academic research organization that has led major cardiovascular medicine clinical trials since its inception in 1984—Dr. Sabatine leads large-scale international randomized controlled trials testing novel therapies for cardiovascular care that have shaped the practice of medicine. Dr. Sabatine is a fellow of the American Heart Association, the American College of Cardiology and the European Society of Cardiology.

New lipid drugs: Is LDL done, ready for new targets?

Low-density lipoprotein (LDL) is indisputably causal for cardiovascular disease. The first of the statin trials, the Scandinavian Simvastatin Survival Study (4S) established the cardiovascular benefit of LDL cholesterol lowering in patients with known vascular disease; subsequent trials with statin monotherapy, and the combination of statin plus ezetimibe, have supported a ‘lower is better’ strategy. Added to this, epidemiological studies in non-Western native populations show that lower LDL cholesterol levels are effective in preventing atherosclerotic cardiovascular disease and are safe.

Most recently, genetic insights into proprotein convertase subtilisin kexin type 9 (PCSK9) paved the way for a novel class of therapeutics: the PCSK9 inhibitors. These treatments have been shown to be highly efficacious in lowering LDL cholesterol, reducing cardiovascular events and, to date, are safe over the duration of clinical trials. Moreover, there is no evidence to suggest any threshold in LDL cholesterol lowering for clinical benefit. The key question, therefore, is whether the availability of PCSK9 inhibitors represents the ‘holy grail’ for LDL lowering therapy?

Atherosclerosis is undoubtedly a multifactorial disease in which chronic inflammation plays a key role. Investigators have now turned their attention to consider other targets that contribute to residual risk that persists even at very low LDL cholesterol. Findings from the CANTOS (Canakinumab Anti-inflammatory Thrombosis Outcomes Study) supported the relevance of inflammatory risk, although the search for other novel targets will undoubtedly continue.
