Abstract:
Objective To investigate the effects of levocarnitine combined with urimetazidine on left ventricular remodeling in maintenance hemodialysis(MHD)patients.Methods All of 86 MHD patients and 40 healthy volunteers(health control group)were involved in the study.all of 86 MHD patients were randomly divided into two groups,disease treatment group(46 cases)and disease control group(40 cases),who had undergone hemodialysis for at least 3 months before the study and were in a stable clinical status without signs of infection or disease activity.In disease treatment group,1.0 g of levocarnitine was infused at the end of each dialysis treatment and 20 mg of trimetazidine was taken orally 3 times each day for 6 months,while the parameters for free fatty acid(FFA),free carnitine(FC),inflammation and oxidative stress were studied before and after the treatmenL In disease control group these two drugs were not used.The left ventricular end-diastolic diameter(LVDd),left ventricuhr end-systolic diameter(LVDs),left atrial diameter (LAD),left ventricular posterior wall thickness(LVPWT),interventricular septal thickness(IVST)and left ventricular ejection fraction(LVEF)were detected by ultrasonic cardiography.Results Before treatment,the serum levels of FFA,high-sensitivity C-reactive protein(hs-CRP),intedeukin(IL)-1β,IL-6,tumor necrosis factor(TNF)-αand malondialdehyde(MDA)were higher in disease treatment group and disease control group than those in health control group(P<0.05 or<0.01),while the serum levels of FC,glutathione peroxidase(GSHPx)and superoxide dismutase(SOD)were lower in disease treatment group and disease control group than those in health control group(P<0.05 or<0.01).Compared with those before treatment,the serum levels of FFA,hs-CRP,IL-1β,IL-6,TNF-α,MDA were decreased(P<0.05 or<0.01),FC,GSHPx,SOD were increased(P<0.05 or<0101),the scores of LVDd,LAD,IVST,LVPWT,LVMI were also decreased significantly(P<0.05),while LVEF increased markedly after treatmem in disease treatment group(P<0.05).There were significant differences in all indexes between disease treatment group and disease control group(P<0.05 or<0.01).Conclusion Supplements of levocarnitine combined with trimetazidine in MHD patients appear to be associated with an improvement of left ventricular remodeling.
