[摘要] 目的 觀察血清腦鈉肽水平在心臟瓣膜手術患者圍術期的變化,并探討其臨床意義。 方法 選取2010年6月~2012年6月在筆者所在醫院進行心臟瓣膜置換術的60例患者,動態監測患者術前、術后6、24、48 h及術后1周血清腦鈉肽水平。 結果 術前心功能Ⅱ 級、Ⅲ級、Ⅳ級患者血清BNP水平之間比較,差異有統計學意義(P<0.01)。術后24、48 h及術后1周血清 BNP 水平顯著高于術前,差異有統計學意義(P<0.05)。術后48 h濃度最高,術后1周明顯下降,但仍高于術前水平,差異有統計學意義(P<0.05)。 結論 BNP水平的變化可以準確反映心臟瓣膜手術患者圍術期心功能的狀況,對術前病情評估、手術時機的選擇及術后處理的指導具有重要的參考意義。

[Abstract] Objective To observe the serum BNP concentration change in heart valve perioperative and explore its clinical significance. Methods 60 cases in our hospital which were treated with the heart valve replacement from June 2010 to June 2012 were selected. The serum BNP levels of patients in preoperative, 6 h of preoperative, 24 h of preoperative, 48 h of preoperative and after one week were dynamically monitored. Results The level of serum BNP levels had significant differences among the preoperative cardiac functional class Ⅱ, class Ⅲ and Ⅳ (P<0.01).The BNP levels of 24 h, 48 h after operation and 1 week after operation were significantly higher than before operation (P<0.05).The concentration of 48 h after operation was the highest, and declined significantly within 1 week after operation, but still higher than preoperative (P<0.05). Conclusion The BNP level changes can accurately reflect the status of perioperative cardiac function of patients with heart valve surgery, and can offer important references to the preoperative condition assessment, the choice of the timing of surgery and postoperative management guidance.

心臟瓣膜病是指各種原因,主要包括炎癥粘連、組織纖維化、先天發育畸形和黏液瘤樣變引起的心臟瓣膜結構和功能上的異常,造成單個或多個心臟瓣膜狹窄或關閉不全類疾病[1-2]。目前,治療心臟瓣膜病的主要途徑是進行外科置換手術[3]。腦鈉肽(BNP)主要是由心室肌細胞合成分泌的,具有利尿、排鈉、擴張血管的作用,是臨床上心功能評價的重要指標之一[4]。近年來,BNP在心血管疾病的診療中備受關注,應用日益廣泛。本研究選取2010年6月~2012年6月在筆者所在醫院進行心臟瓣膜置換術的60例患者,動態監測患者術前、術后6、24、48 h及術后1周血清腦鈉肽水平,現報道如下。
