Abstract

•Statin efficacy in Asians with and without diabetes.•Low-intensity statin was effective in reducing LDL-cholesterol to <100 mg/dL.•Ezetimibe-simvastatin and high-dose atorvastatin significantly elevated HDL-cholesterol.•In diabetes, HDL-cholesterol increased less and LDL-cholesterol decreased more.•There was no significant statin-induced glucose elevation in nondiabetes.

BackgroundIt is difficult to apply the proper intensity of statin for new treatment guidelines in clinical settings because of few data about the statin efficacy in Asians. We conducted a retrospective, observational study to estimate the percentage changes in lipid parameters and glucose induced by different statins.MethodsWe analyzed 3854 patients including those with nondiabetes and diabetes treated at the outpatient clinic between 2003 and 2013 who were statin-naïve and maintained fixed-dose of statin for at least 18 months.ResultsModerate- and low-intensity statin therapy was effective in reducing low-density lipoprotein cholesterol (LDL-C) to <100 mg/dL (70.3%, 83.0%, and 87.2% of diabetic patients in the low-, moderate-, and high-intensity therapy groups, respectively). The rapid decrease of LDL-C was observed in the first 8 months, and LDL-C-lowering effect was maintained throughout the observation period in even the low-intensity statin group. The effects of statins in elevating high-density lipoprotein cholesterol were similar in each statin groups, except the ezetimibe-simvastatin group (4.5 ± 2.1%) and high-dose atorvastatin groups (9.7 ± 3.3% and 8.7 ± 2.4% for 40 mg and 80 mg of atorvastatin/day, respectively). High-density lipoprotein cholesterol increased less and LDL-C decreased more in diabetes than in nondiabetes. There were no significant changes of fasting glucose after statin use in nondiabetic patients.ConclusionsModerate- or low-intensity statin was effective enough in reaching National Cholesterol Education Program Adult Treatment Panel III LDL-C target goals in Koreans. Low-intensity statin showed around 30% LDL-C reduction from the baseline level in Koreans, which is comparable to moderate-intensity statin in new guideline.
