Incidence of myocardial dysfunction in studies with severe sepsis patients is up to two thirds of patients. On the other side, patients with normal echocardiography have some type of myocardial injury, which can be detected by elevated serum levels of troponins and natriuretic peptides. Strong prognostic value of these markers regarding morbidity and mortality of septic patients indicates an important role of this "occult" myocardial injury. Therapeutical interventions should take place only in situation in that low cardiac output is not capable to ensure metabolic demands of tissues. Nowadays, because of detrimental effects of classical inotropes, new strategies are under investigation. Namely levosimendan is promising alternative, not only related to its inotropic effects. Early diagnostics, assessment of prognosis and therapeutic strategy in patients with SMD are challenging for continuing research and for clinicians of different specialities.
在重症脓毒症患者的研究中,心肌功能障碍的发生率高达三分之二的患者。另一方面,超声心动图正常的患者也存在某种类型的心肌损伤,这可以通过血清肌钙蛋白和利钠肽水平升高来检测。这些标志物对脓毒症患者发病率和死亡率具有很强的预后价值,表明这种“隐匿性”心肌损伤具有重要作用。只有在低心输出量无法满足组织代谢需求的情况下才应进行治疗干预。如今,由于传统强心剂的有害作用,新的策略正在研究中。具体而言,左西孟旦是一种有前景的替代药物,不仅与其正性肌力作用有关。对于脓毒症心肌病患者的早期诊断、预后评估和治疗策略,持续研究以及不同专业的临床医生都面临挑战。
