Secondary prevention in coronary heart disease patients with low HDL: which options do we have?

Abstract

Low levels of high-density lipoprotein cholesterol (HDL-C) are frequently encountered in patients with coronary artery disease (CAD), most often in combination with elevated triglycerides as part of a dysmetabolic syndrome. Although no large secondary prevention trials with statin therapy with special emphasis on low HDL-C have been performed, some guidance can be extracted from a number of post-hoc analyses on how to treat patients with low levels of HDL-C. In terms of risk reduction, statin therapy appears to be at least as effective in patients with low compared to normal HDL-C levels. Fibrate therapy seems only effective when low HDL-C coincides with a level of low-density lipoprotein cholesterol (LDL-C) in the low-normal range. Before considering combination therapy of statins with fibrates, much emphasis should be put on dietary changes, weight reduction, smoking cessation and regular exercise, since these measures are effective tools to raise HDL-C levels. Moreover, one should be aware of the fact that combination therapy of statins and fibrates is not evidence-based and confers some potential risk of myopathy. Future therapy options may include CETP (cholesterol ester transfer protein) inhibitors, but these agents are still in an experimental phase. As most patients with low HDL-C levels share features of the dysmetabolic syndrome, one could also consider a combination therapy of statins and ACE-inhibitors, since this combination is not only safe, but the individual preventive effects of these compounds appear to be cumulative.
