Fibrates in primary prevention of cardiovascular disease. Comments on the results of a systematic review of the Cochrane Collaboration.

Fibrates are drugs that reduce triglycerides, elevate high-density lipoproteins, as well as decrease small, dense LDL particles. The results of a study have recently been published by the Cochrane Collaboration on fibrates efficacy and safety in the primary prevention of cardiovascular disease. This study includes a systematic review and a meta-analysis of 6 studies (16,135 patients) that evaluated the clinical benefits of fibrates compared to placebo use or other lipid-lowering drugs. This review showed evidence of a protective effect of the fibrates compared with placebo as regards a reduction 16% of a compound objective of death due to cardiovascular disease, non-fatal myocardial infarction, or non-fatal cerebrovascular accident (NNT: 112), and that reduce coronary morbidity and mortality by 21% (NNT: 125). In addition, fibrates could reduce previously established diabetic retinopathy. However, fibrates do not influence total mortality, or non-cardiovascular mortality. Its joint use with statins does not benefit patients without established cardiovascular disease, compared to the use of statins in monotherapy. Fibrates are safe, although they can elevate serum creatinine levels.
