[摘要] 目的 探讨左西孟旦联合无创正压通气(NPPV)治疗急性心肌梗死(AMI)后急性左心衰竭的临床效果及安全性。 方法 选取2012年1月~2014年12月在本院心内科诊断为AMI合并急性左心衰竭的患者62例,所选患者均在常规药物治疗无效的基础上,给予左西孟旦联合NPPV治疗。观察治疗前及治疗24 h及72 h后,呼吸困难程度及全身临床状况、氧分压、N末端脑利钠肽前体(NT-proBNP)、超敏C反应蛋白(hs-CRP)的变化。 结果 与治疗前比较,治疗后,患者的呼吸困难程度评分[24 h(1.32.±0.56)分及72 h(1.21±0.53)分]及全身临床状况评分[24 h(1.16±0.61)分及72 h(1.10±0.58)分]明显改善,氧分压[24 h(91.6±7.2)mmHg ]明显升高(P<0.05),NT-proBNP 水平明显降低[72 h(1435.3±397.8)ng /L](P<0.05),hs-CRP也明显降低[72 h(3.8±1.7)mg/L](P<0.05)。 结论 左西孟旦联合NPPV治疗急性心肌梗死后急性左心衰竭的效果显著,能够较快改善临床症状,提高氧分压,降低NT-proBNP、hs-CRP水平,耐受性和安全性良好。

[Abstract] Objective To probe into the clinical efficacy and safety of levosimendan combined with noninvasive positive pressure ventilation (NPPV) in the treatment of acute left heart failure after acute myocardial infarction (AMI). Methods From January 2012 to December 2014,62 patients diagnosed as AMI complicated with acute left heart failure in our craniological department of our hospital were selected.On the ineffective basis with conventional drug treatment for selected patients,they were given levosimendan combined with NPPV treatment.The change of dyspnea degree,general clinical status,oxygen partial pressure,N-terminal pro-brain nitric peptide (NT-proBNP),and high-sensitivity C-reactive protein (hs-CRP) were observed before treatment and after 24 h and 72 h treatment. Results Compared with before treatment,score of dyspnea degree [24 h (1.32.±0.56) points and 72 h (1.21±0.53) points] and general clinical status [24 h (1.16±0.61) points and 72 h (1.10±0.58) points] was obviously improved,and oxygen partial pressure [24 h (91.6±7.2) mmHg] was significantly increased,and NT- proBNP [72 h (1435.3±397.8)ng/L] and hs-CRP [72 h (3.8±1.7) mg/L] level was obviously decreased (P<0.05). Conclusion Levosimendan combined with NPPV in the treatment of acute left heart failure after acute myocardial infarction can obtain a remarkable effect,and quickly improve clinical symptoms and oxygen partial pressure,and decrease NT-proBNP and hs-CRP level with good tolerance and safety.

急性左心衰竭是急性心肌梗死常见的并发症之一,一旦发生说明心肌梗死面积大,顿抑心肌广泛,心功能进行性下降,死亡率高。目前快速缓解急性左心衰竭临床症状仍以强心、利尿、扩血管为主,传统的强心药物在心肌梗死的急性期会增加心肌耗氧量,延缓心功能的改善,而新型钙离子增敏剂——左西孟旦具有增强心肌收缩力、降低心肌耗氧量、扩张外周血管、改善心力衰竭血流动力学效应的作用,从而改善心力衰竭的临床症状[1]。急性左心衰竭时由于发生间质性肺水肿,导致肺通气及弥散功能障碍,早期应用无创正压通气治疗可有效纠正低氧血症,缩短住院时间,降低病死率[2-3]。本研究通过观察左西孟旦联合无创正压通气治疗急性心肌梗死后急性左心衰竭的相关指标变化情况,评价其临床疗效及安全性,为急性心肌梗死后急性左心衰竭的治疗探讨新的方法。……
