Efficacy and safety of statin combined with ezetimibe for elderly patients with coronary heart disease and dyslipidemia / 中华全科医师杂志

ABSTRACT

Objective:To evaluate the efficacy and safety of statin combined with ezetimibe for elderly patients with coronary heart disease (CHD) and dyslipiclemia.Methods:Clinical data of 293 patients with CHD and dyslipidemia treated with statins and ezetimibe in the outpatient clinic of Beijing Hospital from November 2009 to June 2019 were retrospectively analyzed. There were 153 patients aged ≥65 years (elderly group) and 140 patients aged<60 year (control group). The low density lipid cholesterol reduction (ΔLDL-C), LDL-C compliance rate and safety were compared between the two groups.Results:The longest follow-up time was 9 months, the average follow-up time was 5.3 months in the elderly group, and 5.2 months in the control group. After treatment the TC, LDL-C, and TG levels were lower than those before treatment in both groups ( P<0.05), and there was no significant changed in HDL-C levels. After treatment there were no significant differences in TC [3.50(3.15,4.01) vs.3.49(3.14,4.00) mmol/L], LDL-C [1.85(1.56,2.23) vs.1.85(1.56,2.40) mmol/L], and TG [1.23(0.94,1.57) vs.1.32(0.84,1.70)mmol/L] between two groups (all P>0.05). There were also no significant differences in ΔLDL-C [-0.85(1.14,-0.55) vs.-0.81 (-1.34, -0.50) mmol/L], LDL-C decline rate (29.3% vs. 28.5%), and LDL-C compliance rate [44.4%(68/153) vs.45.0%(63/140)] between two group (all P>0.05). After combined treatment, AST and ALT increased in both groups, but they were still in the normal range. The difference of AST and ALT before and after treatment in the two groups was not statistically significant. There were no significant changes in CK in both groups ( P>0.05). Conclusion:The combined administration of ezetimibe and statin can significantly reduce LDL-C level and increase LDL-C compliance rate in treatment of elderly patients with coronary heart disease and dyslipidemia safety.
