Beyond the statins: new therapeutic perspectives in cardiovascular disease prevention.
Reduction of low-density lipoprotein cholesterol (LDL-C) with statin therapy is currently identified in treatment guidelines as the primary focus for patients with or at risk of coronary heart disease (CHD). Yet despite effective statin therapy there is still an unacceptably high residual coronary risk. A substantial proportion of patients with CHD have mixed dyslipidemia, including low levels of high-density lipoprotein cholesterol (HDL-C), an independent and predictive risk factor for CHD. Although effective in reducing LDL-C, statin therapy has only modest effects in raising HDL-C. Fibrate therapy is an alternative lipid-modifying strategy, and is effective in reducing CHD mortality and morbidity, with the magnitude of clinical benefit similar to statin therapy. Multi-drug therapy with complementary mechanisms of action has been proposed as a means of improving lipid-modifying efficacy. Nicotinic acid is the most potent agent for increasing HDL-C and also substantially reduces LDL-C and triglycerides. Addition of nicotinic acid to statin therapy would be a logical management approach, given the potential for complementary therapeutic benefit. The clinical benefits of this combination are supported by the results of the HDL Atherosclerosis Treatment Study, which showed reduction of 60-90% in the incidence of major coronary events when both agents were administered. In addition, combination treatment led to angiographic regression of stenosis, compared with placebo, rather than slowed progression as previously reported with statin monotherapy. Given that the prevalence of low HDL-C, particularly amongst individuals with CHD, is higher than previously anticipated, combining nicotinic acid and a statin represents an innovative approach to further reducing CHD risk.
