摘要：Background The prognosis for patients with heart failure (HF), including cardiogenic shock (CS), complicating acute coronary syndrome (ACS) remains poor.; Objective This study aimed to review the relevant literature and evaluate whether levosimendan was associated with better clinical outcomes in these patients.; Methods We searched PubMed, EMBASE, and the Cochrane library databases for randomized controlled trials that investigated levosimendan compared with any control in patients with HF/CS complicating ACS.; Results A total of 1065 patients from nine trials were included in this study. Analysis showed that levosimendan significantly reduced total mortality and the incidence of worsening HF. In patients with HF-ACS, levosimendan was associated with reduced mortality. In patients with CS-ACS, no significant difference was observed between the two groups. Levosimendan contributed to significantly reduced mortality when compared with placebo, but no significant reduction was seen compared with dobutamine. Compared with controls, levosimendan decreased pulmonary capillary wedge pressure and systemic vascular resistance and increased cardiac index, with no significant difference observed between the groups in terms of heart rate. Levosimendan non-significantly increased the risk of hypotension but did not increase the risk of ischemic episodes, sinus tachycardia, atrial fibrillation, or ventricular arrhythmias.; Conclusion Levosimendan appears to be a promising drug to reduce mortality and worsening HF in patients with HF/CS-ACS. It appears to provide hemodynamic benefit and was associated with an increased risk of hypotension.
