目的探讨米力农联合正压机械通气治疗急性心肌梗死并急性左心衰竭的临床效果。方法选取2010年1月至2014年6月急性心肌梗死并发急性左心衰竭患者114例,随机分为两组,每组57例。对照行常规治疗,观察组加用正压机械通气及正性肌力药米力农治疗,比较两组治疗效果。结果治疗后,观察组总有效率(89.47%)高于对照组(63.16%),差异有统计学意义(P<0.05)。治疗后观察组室性早搏个数(1012±93)个/d、LVEF(51±8)%和LVEDD(49±5)mm优于对照组,差异均有统计学意义(P<0.05)。结论正压机械通气及米力农可改善患者心功能,降低死亡率。
Objective To investigate the clinical effect of milrinone combined with positive pressure mechanical ventilation in patients with acute myocardial infarction and acute left heart failure. Methods From January 2010 to June 2014, 114 patients with acute myocardial infarction complicated by acute left heart failure were randomly divided into two groups of 57 cases. Control routine treatment, the observation group plus positive pressure mechanical ventilation and positive force drug Milrinone treatment, the two groups were compared. Results After treatment, the total effective rate (89.47%) in the observation group was higher than that in the control group (63.16%), with significant difference (P <0.05). After treatment, the number of ventricular premature beats in the observation group was 1012 ± 93 / d, and the LVEF 51 ± 8% and LVEDD 49 ± 5 mm were superior to the control group (P <0.05). Conclusion Positive pressure mechanical ventilation and milrinone can improve cardiac function and reduce mortality.
