Cholesterol lowering, sudden cardiac death and mortality

Abstract

Sudden cardiac death is the main cause of cardiac mortality. Is blood cholesterol a determinant of sudden cardiac death? Does cholesterol lowering result in fewer sudden cardiac deaths? Answering these two questions may shed a new light on the epidemiology of coronary heart disease and on prevention options. In fact, careful analysis of the available data, including randomised trials, indicates that, contrary to a widespread opinion, cholesterol lowering does not appear to be a very effective way of reducing cardiac and overall mortality in the general population.
