Abstract:
Objective To observe the efficacy and safety of trimetazidine/coenzyme Q10 combination in the treatment of the elderly patients with chronic heart failure(CHF).Methods Sixty-two male patients aged over 80 years with CHF were randomly divided into intervention group and control group.Patients in control group received optimal conventional CHF therapy according to the guideline for CHF,while patients in intervention group received trimetazidine of 20 mg,3 times per day,coenzyme Q10 20 mg,3 times per day,additionally for 6 weeks.Left ventricular ejection fraction (LVEF),left ventricular end diastolic diameter (LVEDD),plasma brain natriuretic peptide (BNP),6 min walking distance (6MWT) and NYHA cardiac function classification of two groups before and after treatment were observed.Results Before treatmen,the NYHA function class of patients in intervention and control groups were 2.8±0.7,2.7±0.7 respectively,after treatment were 2.1± 0.6,2.4 ± 0.7 respectively,the differences were significant before and after treatment (t=6.808,2.249;P＜0.01,P＜0.05).Before treatment,BNP of intervention and control groups were (540±351)ng/L,(483 ± 351) ng/L respectively,after treatment were (219± 172) ng/L,(316 ± 202) ng/L respectively,the differences were significant before and after treatment (Z =-4.927,-4.042;P ＜ 0.01).Moreover,after treatment,NYHA function class and plasma BNP in intervention group were significantly better than those in control group (t =-2.109,P ＜ 0.05;Z =-2.219,P ＜ 0.05).Before treatment,LVEF,LVEDD and 6MWT of intervention group were (44.3 ± 3.1) ％,(54.0 ± 4.7) mm and (217.0 ± 60.9) m respectively,after treatment were (46.8±3.9) ％,(53.2±4.3) mm and (267.0±91.1) m respectively,the differences were significant before and after treatment(t=-8.313,2.254,-4.561;P＜0.01 or P＜0.05).Moreover,after treatment,LVEF and 6MWT in intervention group were significantly better than those in control group ((44.9± 3.5)％,(213.2 ±78.1) m;t =2.000,2.186;P ＜ 0.05).No significant adverse events were detected in the intervention group.Conclusion Combination of trimetazidine and coenzyme Q10 on the basis of the conventional treatment in the elderly with CHF,can further improve cardiac dysfunction and have a good safety.
