Abstract:
Objective:To study influence of amlodipine combined enalapril antihypertensive therapy on renal function in aged patients with essential hypertension (EH) complicated coronary heart disease (CHD).Methods:A total of 120 aged EH + CHD patients in our hospital from Feb 2014 to Apr 2016 were enrolled.Patients were randomly and equally divided into amlodipine group,enalapril group and combined treatment group (received amlodipine com-bined enalapril treatment ),all groups were treated for 12 weeks.Total effective rate,standard-reaching condition of blood pressure,urinary albumin excretion rate (UAER),levels of serum creatinine (Scr),cystatin C (CysC) and blood urea nitrogen (BUN) before and after treatment,and incidence of adverse reactions were measured and com-pared among three groups.Results:There was no significant difference in total effective rate among three groups,P＝0.139.Compared with amlodipine group and enalapril group,there was significant reduction in standard-reaching time of blood pressure [ (10.84 ± 2.79) months vs.(10.75 ± 3.31) months vs.(8.20 ± 1.46) months] in com-bined treatment group,P＝0.001 all.Compared with before treatment,after 12-week treatment,there were sig-nificant reductions in UAER,levels of Scr,serum CysC and BUN in amlodipine group and combined treatment group,P＜0.05 or ＜ 0.01;compared with amlodipine group and enalapril group after 12-week treatment,there were significant reductions in UAER [(130.55 ± 12.72) μg/min vs.(135.63 ± 17.64) μg/min vs.(112.25 ± 13.34) μg/min],levels of Scr [ (79.32 ± 6.13) μmol/L vs.(80.25 ± 5.97) μmol/L vs.(68.04 ± 5.56) μmol/L],serum CysC [ (1.14 ± 0.23) mg/L vs.(1.21 ± 0.26) mg/L vs.(0.76 ± 0.17) mg/L] and BUN [ (5.16 ± 1.13) mmol/L vs.(5.79 ± 1.03) mmol/L vs.(4.23 ± 0.56) mmol/L] in combined treatment group,and BUN level of amlodip-ine group was significantly lower than that of enalapril group,P＜0.05 or ＜0.01.There was no significant differ-ence in incidence rate of adverse reactions during treatment among three groups,P＝0.757.Conclusion:Small dose amlodipine combined enalapril is effective on controlling blood pressure in aged EH + CHD patients.Compared with monotherapy,it possesses better protection on renal function with high safety,which is worth extending.
