Improving The Odds: Ezetimibe And Cardiovascular Disease

The beauty of science is that well-conducted experiments provide answers to questions which were posed in times of greater ignorance. Cardiovascular disease (CVD) is the leading cause of death worldwide and will be for some time. Cholesterol is a critical player which drives the underlying pathophysiological process of atherosclerosis. Statins are the first line treatment for lipids in CVD given their ability to low-density lipoprotein cholesterol (LDL-C) by up to 50%, and their proven benefits in both primary and secondary intervention . Despite the unprecedented efficacy of statins, additional treatments are sought to potentially reduce the residual risk that remains despite statin treatment such as that associated with reduced high-density lipoprotein cholesterol levels (HDL-C) or triglycerides . In the last 5years, several trials have reported on their potential additional benefit beyond statin therapy. These include omega-3 fatty acids in patients with prediabetes or diabetes , fibrates in diabetes , nicotinic acid/niacin in cardiovascular disease and cholesterol ester transfer protein inhibitors in cardiovascular disease . Despite their promise, none of these treatments were able to demonstrate benefit beyond baseline statin therapy when compared with placebo . The idea that benefit beyond statin treatment may be an unachievable goal has dogged the medical community working on CVD prevention. The phrase, Statins for atherosclerosis - as good as it gets?' was coined in 2005 and has rung true up until now (8).
