摘要
左西孟旦为钙离子增敏剂,通过肌钙蛋白C对钙离子的增敏作用来提高心肌收缩力,且不增加细胞内环磷腺苷和细胞内钙离子浓度。左西孟旦具有正性肌力作用但不提高细胞内钙离子浓度和心肌耗氧量,可降低危重症患者的死亡率,在心脏围手术期有应用价值。该文对左西孟旦的药理作用、药代动力学及在心衰患者围手术期应用进行综述,为其进一步临床使用提供参考。
Levosimendan is a kind of calcium sensitizers. It imProves myocardial contractility by sensitization of troPonin C to calcium without increasing intracellular cAMP or intracellular calcium concentration. Levosimendan has a Positive inotroPic effect without increas-ing the intracellular calcium ion concentration and myocardial oxygen consumPtion, and can reduce mortality in critically ill Patients, has aPPlication value in the PerioPerative cardiac surgery Period. This review summarize the Pharmacology and Pharmacokinetics of levosi-mendan and aPPlication of levosimendan in Patients with heart failure in PerioPerative Period, in order to Provide reference for its further clinical aPPlication.
