目的:探讨急性心肌梗死(AMI)早期静脉及口服应用美托洛尔对心率变异性(HRV)的影响。方法:将我院2012年1月-2012年l2月收治的AMI患者100例随机分为对照组和观察组各50例,对照组予常规药物治疗,观察组在对照组治疗的基础上,予静脉及口服应用美托洛尔治疗4周,比较治疗前、后两组HRV的变化。结果:与治疗前比较,治疗后两组HRV指标均明显改善,但观察组的改善更明显,P均<0.05。结论:早期静脉及口服应用美托洛尔可改善AMI患者的HRV,使失衡自主神经改善。
Objective: To investigate the effect of early intravenous and oral metoprolol on heart rate variability (HRV) in patients with acute myocardial infarction (AMI). Methods: One hundred patients with AMI who were admitted to our hospital from January 2012 to January 2012 were randomly divided into control group and observation group (n = 50). The control group was treated with conventional drugs. On the basis of the treatment of the control group, Intravenous and oral metoprolol treatment for 4 weeks, compared before and after treatment HRV changes in both groups. Results: Compared with those before treatment, the HRV indexes in both groups were significantly improved after treatment, but the improvement in the observation group was more obvious (all P <0.05). CONCLUSION: Early intravenous and oral administration of metoprolol improves HRV in patients with AMI and improves unbalanced autonomic nervous system.
