Abstract:
Objective To observe the clinical efficacy of L-carnitine combined with trimetazidine in the treatment of chronic heart failure.Methods The clinical data of 700 patients with chronic heart failure were retrospectively analyzed.According to different treatment methods,they were divided into four groups:A,B,C,D.181 cases of A group used L-camitine combined with trimetazidine treatment on the basis of routine treatment.177 cases of B group received L-carnitine treatment on the basis of routine treatment.175 cases of C group received trimetazidine treatment on the basis of routine treatment.167 cases of D group received conventional treatment.Then,the clinical efficacy of the four groups was compared.Results The total effective rates of A,B,C,D groups were 83.43％,76.84％,73.71％,62.28％,respectively.The total effective rate of A group was obviously higher than the other groups,the difference was statistically significant(x2 =22.40,P ＜0.05).There was no significant difference in total effective rate between B group and C group (x2 =0.46,P ＞ 0.05),but both B and C groups were obviously better than group D (x2=4.37,5.13,all P ＜ 0.05).The data before and after treatment in four groups were significantly improved,such as 6MWT,NT-proBNP,LVEF and FS(A group:t =33.856,37.474,17.722,31.250,B group:t =27.328,31.559,6.863,25.581,C group:t =23.430,32.640,9.524,16.923,D group:t =15.863,9.602,3.061,10.169,all P ＜ 0.01).In the above four indicators,those in A group were obviously better than B group,C group and D group (F =5.884,38.621,4.357,13.770,all P ＜ 0.01).Conclusion L-carnitine combined with trimetazidine can improve the abnormal metabolism of myocardium,optimize the energy metabolism pathway of myocardium,improve the short-term cardiac function of patients markedly.L-carnitine combined with trimetazidine is worthy of promoting joint use.
