Abstract

Objectives The aim of this study was to investigate the relationship between lipid and nonlipid biomarker levels achieved during statin therapy and the incidence of major cardiovascular events (MCVEs) in patients with stable coronary heart disease (CHD). Background Several plasma nonlipid biomarkers have been shown to predict MCVEs in population studies. Methods This is a nested case-control study in the TNT (Treating to New Targets) study population, a randomized trial that compared the efficacy of high- (80 mg) versus low-dose (10 mg) atorvastatin for the secondary prevention of CHD. Fasting plasma levels of standard lipids and of 18 nonlipid biomarkers were obtained after an 8-week run-in period on atorvastatin 10 mg and again 1 year after being randomized to 10 or 80 mg atorvastatin in 507 patients who experienced MCVEs during the 4.9 years of study follow-up and in 1,020 control subjects. An MCVE was defined as CHD death; nonfatal, nonprocedure-related myocardial infarction; resuscitated cardiac arrest; or fatal or nonfatal stroke. Results Low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and triglycerides were all predictive of recurrent MCVEs (p ≤ 0.009). Concentrations of many of the 18 nonlipid biomarkers were lowered by atorvastatin therapy (independent of dose). However, almost none of the nonlipid biomarker levels, whether measured after the 8-week run-in period or after 1 year of treatment with 10 or 80 mg atorvastatin, were predictive of recurrent MCVEs. Conclusions In patients with stable CHD, atorvastatin improved plasma levels of an expanded panel of nonlipid biomarkers. However, independently of atorvastatin dose, the achieved levels of the vast majority of nonlipid biomarkers did not predict MCVEs.
