[摘要] 目的 探討左西孟旦聯合無創正壓通氣(NPPV)治療急性心肌梗死(AMI)后急性左心衰竭的臨床效果及安全性。 方法 選取2012年1月~2014年12月在本院心內科診斷為AMI合并急性左心衰竭的患者62例,所選患者均在常規藥物治療無效的基礎上,給予左西孟旦聯合NPPV治療。觀察治療前及治療24 h及72 h后,呼吸困難程度及全身臨床狀況、氧分壓、N末端腦利鈉肽前體(NT-proBNP)、超敏C反應蛋白(hs-CRP)的變化。 結果 與治療前比較,治療后,患者的呼吸困難程度評分[24 h(1.32.±0.56)分及72 h(1.21±0.53)分]及全身臨床狀況評分[24 h(1.16±0.61)分及72 h(1.10±0.58)分]明顯改善,氧分壓[24 h(91.6±7.2)mmHg ]明顯升高(P<0.05),NT-proBNP 水平明顯降低[72 h(1435.3±397.8)ng /L](P<0.05),hs-CRP也明顯降低[72 h(3.8±1.7)mg/L](P<0.05)。 結論 左西孟旦聯合NPPV治療急性心肌梗死后急性左心衰竭的效果顯著,能夠較快改善臨床癥狀,提高氧分壓,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見的并發癥之一,一旦發生說明心肌梗死面積大,頓抑心肌廣泛,心功能進行性下降,死亡率高。目前快速緩解急性左心衰竭臨床癥狀仍以強心、利尿、擴血管為主,傳統的強心藥物在心肌梗死的急性期會增加心肌耗氧量,延緩心功能的改善,而新型鈣離子增敏劑——左西孟旦具有增強心肌收縮力、降低心肌耗氧量、擴張外周血管、改善心力衰竭血流動力學效應的作用,從而改善心力衰竭的臨床癥狀[1]。急性左心衰竭時由于發生間質性肺水腫,導致肺通氣及彌散功能障礙,早期應用無創正壓通氣治療可有效糾正低氧血癥,縮短住院時間,降低病死率[2-3]。本研究通過觀察左西孟旦聯合無創正壓通氣治療急性心肌梗死后急性左心衰竭的相關指標變化情況,評價其臨床療效及安全性,為急性心肌梗死后急性左心衰竭的治療探討新的方法。……
