Objective: To investigate the therapeutic effects of esmolol on sympathetic storm patients caused by acute myocardial infarction (AMI).Methods: Clinical data of 50 patients who were treated in our hospital and had sympathetic stormcaused by AMI were analyzed retrospectively.The patients were divided into control group and observation group according the therapy method.The control group was treated with electric cardioversion, amiodarone or lidocaine,while the observation group was additionally treated with intravenous esmolol administration. Heart rate and blood pressure changes of the two groups were observed after treatment.The difference of cardioversion number and cardiac incidence were compared between the two groups.Results: After treatment,indexes of heart rate, systolic blood pressure and diastolic blood pressure in the observation group were lower than those in the control group (all P<0.05);observation group had a better cardiac condition than that of control group(P<0.05).Compared with the control group,the number of electrical complex rate in the observation group was significantly lower and the difference was statistically significant (P<0.05). Furthermore, the incidence of complications such as bradycardia,hypotension and cardiac insufficiency in the observation group was significantly lower than that in the control group. Conclusion: Esmolol has therapeutic effectiveness on sympathetic storm patients caused by AMI, which was embodied by significantly improving blood pressure,heart rate and reducing the electrical cardioversion times. Esmolol has better value in clinical applications. |
