The heart is one of the organs most vulnerable to sepsis. This review describes the general characteristics of sepsis-induced cardiomyopathy and the main pathogenesis of myocardial dysfunction in sepsis. Levosimendan is a novel drug for treatment of sepsis-induced myocardial dysfunction. This review also elaborates on the pathogenesis of levosimendan, including the mechanisms of its anti-inflammatory effects, improvement of myocardial ischaemia, increased synthesis of nitric oxide, vascular endothelial cell protection, increased myocardial contractility, improved diastolic function, and inhibition of hypoxia-inducible factor-1α expression. Many clinical studies have proven that levosimendan effectively prevents myocardial dysfunction in sepsis. In addition to the widespread use of levosimendan in patients with heart failure, the role of levosimendan in the treatment of patients with sepsis-induced cardiomyopathy will be increasingly studied and applied in the future.
