ABSTRACT
Objective To investigate the clinical efficacy of amiodarone combined with succinylmetroprolol sustained-release tablets in patients with atrial fibrillation and congestive heart failure (CHF) complicated with atrial fibrillation (AF), and to observe the effect of amiodarone on heart function and ventricular rate.MethodsIn people's hospital of Anji county from June 2013 to June 2016 a total of 80 patients with atrial fibrillation and heart failure were enrolled in this study.The patients were randomly divided into control group and treatment group, 40 cases.(Ventricular rate, resting ventricular rate), cardiac function (ejection fraction-EF, stroke volume-SV, cardiac output-CO and left ventricular function) were measured before treatment and 6 months after treatment Ventricular end-diastolic early/late peak velocity ratio-VA/VE).The clinical efficacy and side effects during the treatment were statistically analyzed.ResultsThe ventricular rate and resting ventricular rate after exercise were significantly lower than those before treatment, but the ventricular rate and resting ventricular rate were significantly lower in the treatment group than those in the control group after 6 months of treatment (P<0.05).The VA/VE was significantly lower than that of the control group at 6 months after treatment, and the values of EF, SV and CO were significantly higher than those of the control group at 6 months after the treatment, SV, CO were significantly higher than the control group(P<0.05).Treatment group, the total effective rate was 92.5%, significantly higher than the control group 72.5%(χ2=7.77, P=0.02).No significant adverse reactions during treatment.ConclusionRapid ventricular rate of atrial fibrillation with congestive heart failure were treated with amiodarone combined with metoprolol succinate sustained release tablets can conducive to the ventricular rate and heart function of patients, and the effect is remarkable, safe, so it can be recommended as the drug of choice for clinical treatment of patients.
