Effect and safety of Reteplase for Injection combined with reduced glutathione in treatment of acute ST segment elevation myocardial infarction / 药物评价研究

ABSTRACT

Objective To research the effect and safety of Reteplase for Injection combined with reduced glutathione in the treatment of acute ST segment elevation myocardial infarction.Methods Patients with acute ST segment elevation myocardial infarction (90 cases) in Jianli People's Hospital from February 2015 to February 2016 were selected and divided equally into A,B and C groups according to different treatment methods.Totally 30 patients in group A were given conventional therapy,30 patients in group B were given reduced glutathione for treatment on the basis of conventional treatment,and the other 30 in group C were given combined therapy of reteplase and reduced glutathione on the basis of conventional treatment.The vascular recanalization rate,improvement of effective indicators including creatine kinase isoenzyme (CKMB),troponin Ⅰ (cTnⅠ),left ventricular end diastolic diameter (LVEDd) and left ventricular ejection fraction (LVEF),oxidative stress kinase including superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px),and incidence of adverse events of patients were compared among the three groups.Results After thrombolysis,the vascular recanalization rate of group C at different time points (2 h,6 h and 12 h) showed significant difference compared with those of groups A and B (P ＜ 0.05).After the treatment,the effective indicators of the three groups were both significantly improved (P ＜ 0.05),and group C improved more significantly than groups A and B (P ＜ 0.05).After the treatment,the SOD and GSH-Px of groups B and C both significantly improved than group A (P ＜ 0.05),but there was no significant difference between groups B and C.After treatment,the incidence of adverse events of group C was significantly lower than those of groups A and B (P ＜ 0.05).Conclusion Reteplase for Injection combined with reduced glutathione has significant curative effect in the treatment of acute ST segment elevation myocardial infarction,which can effectively improve the cardiac function and inhibition of oxidative stress.It is of higher security but with lower incidence of adverse events.
