目的探讨比索洛尔治疗心肌梗死并心功能不全的临床疗效及其安全性。方法选取绵竹市中医医院2014年2月—2016年2月收治的急性心肌梗死并心功能不全患者80例,按照随机数表法分为对照组和观察组,各40例。对照组患者入院后给予常规治疗,观察组患者在对照组基础上加用比索洛尔治疗,两组患者均持续治疗6个月。比较两组患者治疗前后收缩压、舒张压、心率,心功能指标[左心室舒张末期容积(LVEDV)、左心室收缩末期容积(LVESV)、左心室射血分数(LVEF)]变化情况及心律失常、预后情况。结果治疗前,两组患者收缩压、舒张压、心率比较,差异无统计学意义(P>0.05);治疗后,观察组患者收缩压、舒张压、心率低于对照组(P<0.05)。治疗前,两组患者LVEDV、LVESV、LVEF比较,差异无统计学意义(P>0.05);治疗后,观察组患者LVEDV、LVESV低于对照组,LVEF高于对照组(P<0.05)。观察组患者心律失常发生率、病死率低于对照组(P<0.05)。结论比索洛尔治疗心肌梗死并心功能不全的临床疗效确切,可有效改善患者心率及心功能,降低血压,利于改善患者预后,且安全性好。
Objective To investigate the clinical efficacy and safety of bisoprolol in the treatment of myocardial infarction with cardiac insufficiency. Methods 80 patients with acute myocardial infarction and cardiac insufficiency admitted from February 2014 to February 2016 in Mianzhu Hospital of Traditional Chinese Medicine were divided into control group and observation group according to the random number table. Patients in the control group were given routine treatment after admission. The patients in the observation group were treated with bisoprolol on the basis of the control group, and both groups were treated for 6 months. The changes of systolic blood pressure, diastolic blood pressure, heart rate, cardiac function index (left ventricular end-diastolic volume, left ventricular end-systolic volume, left ventricular ejection fraction, LVEF) and arrhythmia were compared between the two groups before and after treatment Prognosis. Results Before treatment, there was no significant difference in systolic blood pressure, diastolic blood pressure and heart rate between the two groups (P> 0.05). After treatment, systolic blood pressure, diastolic blood pressure and heart rate were lower in the observation group than those in the control group (P <0.05). Before treatment, LVEDV, LVESV and LVEF were not significantly different between the two groups (P> 0.05). After treatment, LVEDV and LVESV in the observation group were lower than those in the control group, and LVEF was higher in the observation group than in the control group (P <0.05). The incidence of arrhythmia and mortality in observation group were lower than those in control group (P <0.05). Conclusion Bisoprolol treatment of myocardial infarction with heart failure and clinical efficacy of the exact, can effectively improve the patient’s heart rate and heart function, lower blood pressure, which will help improve the prognosis of patients with good safety.
