The efficacy evaluation of carvedilol in the treatment of 60 chronic heart failure patients with arrhythmias

Objective To investigate the clinical effect of carvedilol in the treatment of chronic heart failure patients with arrhythmia.Methods 120 cases of hospitalized cases of cardiology were randomly divided into treatment and control groups by checking the random number table.The control group was given benazepril hydrochloride combined digoxin cardiac medicine and furosemide or hydrochlorothiazide,spironolactone and other diuretics in the treatment.The treatment group was given carvedilol based on the treatment of the control group.Followed up for 12 weeks,the clinical manifestations,blood pressure and heart rate,left ventricular ejection fraction(EF) and arrhythmias before and after treatment were obsered,and to determine the efficacy.Results The treatment group decreased heart rate,corrected ventricular premature contraction,ventricular contraction and ventricular tachycardia in comparison with the control group with significant differences(t =6.018、5.319、7.623、6.194、7.562,all P ＜0.001 ),and there was a significantly statistical significance( P ＜ 0.01 ) that the treatment group can increase the ejection fraction compared with the control group.The markedly and total efficiency was more effective in the treatment group than the control group,which was statistically significant(x2 =34.301,P ＜0.05).Conclusion There was a positive effect of carvedilol in improving heart function,reduceing arrhythmias and mortality,and reducing hospitalization rate and other aspects.
