Abstract: Background Coronary heart disease (CHD) risk increases with age; yet lipid-lowering therapies are significantly under-utilized in patients > 65 years. The objective was to evaluate the safety and efficacy of lipid-lowering therapies in older patients treated with atorvastatin 10 mg + ezetimibe 10 mg (EZ/Atorva) vs. increasing the atorvastatin dose to 40 mg. Methods Patients ≥ 65 years with atherosclerotic vascular disease (LDL-C ≥ 1.81 mmol/L) or at high risk for coronary heart disease (LDL-C ≥ 2.59 mmol/L) were randomized to EZ/Atorva for 12 wk vs. uptitration to atorvastatin 20 mg for 6 wk followed by atorvastatin 40 mg for 6 wk. The percent change in LDL-C and other lipid parameters and percent patients achieving prespecified LDL-C levels were assessed after 12 wk. Results EZ/Atorva produced greater reductions in most lipid parameters vs. uptitration of atorvastatin in patients ≥ 75 years (n = 228), generally consistent with patients 65–74 years (n = 812). More patients achieved LDL-C targets with combination therapy vs. monotherapy in both age groups at 6 wk and in patients ≥ 75 years at 12 wk. At 12 wk, more patients ≥ 75 years achieved LDL-C targets with monotherapy vs. combination therapy. EZ/Atorva produced more favorable improvements in most lipids vs. doubling or quadrupling the atorvastatin dose in patients ≥ 75 years, generally consistent with the findings in patients 65–74 years. Conclusions Our results extended previous findings demonstrating that ezetimibe added to a statin provided a generally well-tolerated therapeutic option for improving the lipid profile in patients 65 to 74 years and ≥ 75 years of age.
