Efficacy of Metoprolol Succinate Sustained Release Tablets Combined with Wenxin Granules in the Treatment of Coronary Heart Disease Arrhythmia

Objective:To explore the effect of metoprolol succinate sustained-release tablets combined with Wenxin Granules in the treatment of coronary heart disease patients with arrhythmia.Methods:The research objects were 50 patients with arrhythmia who were treated in our hospital from September 2019 to September 2020.According to different treatment methods,they were divided into observation group(Wenxin Granule+metoprolol succinate treatment)and control group(metoprolol succinate treatment),25 cases in each group.The curative effects of the two groups were compared.Results:After treatment,there was no significant difference in rnn50,RMSSD,sdnni and SDANN between the two groups(P>0.05).Compared with the control group,the SDNN in the observation group was higher than that in the control group(P<0.05);Before treatment,there was no significant difference in the above indexes between the two groups(P>0.05);The effective rates of the observation group and the control group were 92.00%and 68.00%respectively,and the curative effect of the observation group was higher than that of the control group(P<0.05);There was no significant difference in the incidence of adverse reactions between the two groups(P>0.05).Conclusion:In the treatment of patients with coronary heart disease and arrhythmia,Wenxin Granule Combined with metoprolol succinate sustained-release tablets has significant effect,which can effectively improve the dynamic electrocardiogram indexes of patients,improve the clinical efficacy,and has high safety.

Effect of Wenxin granule on Bcl-2/Bax/Caspase apoptosis pathway gene expression in rats with myocardial infarction

Objective:To explore the cardioprotective mechanism of Wenxin Granules regulating the expression of apoptosis-related genes in cardiomyocytes.Methods:A rat model of myocardial infarction was established and randomly divided into model group,Wenxin granule low-dose group,Wenxin granule high-dose group,metoprolol group and sham operation group.the left ventricular end systole anterior wall thickness(LVAWs),end systole inner diameter(LVIDs),end systole posterior wall thickness(LVPWs),end-diastolic anterior wall thickness(LVAWd),end-diastolic inner diameter(LVIDd),end-diastolic posterior wall thickness(LVPWd)and left ventricular ejection fraction(LVEF)were detected by echocardiography in each group after 2 weeks of treatment.Hematoxylin eosin(HE)staining was used to observe the changes in the cardiac structure of rats in each group.Real-time PCR(Real-time PCR)was used to detect the relative expression of mammalian B-cell lymphoma-2(BCL-2),BCL-2 related X protein(BAX),Caspase-9(Caspase-9),and Caspase-3(Caspase-3)mRNA.TUNEL staining was used to detect changes in the apoptotic rate of rat cardiomyocytes in each group.Results:Compared with the sham operation group,the LVAWs,LVPWs,LVPWd and LVEF of the model group were significantly reduced(P<0.05,P<0.01),and LVIDs and LVIDd were significantly increased(P<0.05,P<0.01).Severe pathological ischemia injury of heart tissue.The relative expression of BCL-2 mRNA and the ratio of BCL-2/BAX in the model group were significantly reduced(P<0.01),while the relative expression of BAX,Caspase-9 and Caspase-3 mRNA was significantly increased(P<0.01).The apoptosis rate was significantly increased(P<0.01).In the low-dose and high-dose groups of Wenxin Granules and the Metoprolol group,LVAWs,LVPWs,LVPW d,and LVEF of rats in each administration group increased significantly(P<0.05,P<0.01),LVIDs,LVIDd was significantly reduced(P<0.05,P<0.01),the pathological damage of the heart tissue was improved,the expression of BCL-2 mRNA and the ratio of BCL-2/BAX were significantly increased(P<0.05,P<0.01),BAX,The expression of Caspase-9 and Caspase-3 mRNA was significantly reduced(P<0.05,P<0.01),and the apoptotic rate of myocardial cells was significantly reduced(P<0.01).Conclusion:Wenxin granule can play a cardioprotective role by regulating the gene expression of BCL-2/BAX/Caspase apoptosis pathway.

Expert Consensus on Wenxin Granule for Treatment of Cardiac Arrhythmias

INTRODUCTIONAntiarrhythmic drugs remain a critically important component of the approach to therapy of cardiac arrhythmias. Over the past 20 years, despite their antiarrhythmic efficacy in many pathological settings, Class Ⅰ and Ⅲ antiarrhythmic drugs have been shown to be associated with the development of proarrhythmias and an increase in the likelihood of causing higher mortality by inducing torsade de pointes ventricular tachycardia and other serious adverse reactions. Consequently, the development of safe and effective antiarrhythmic regimens remains a primary focus of contemporary cardiovascular research.
