Conclusion
In summary, the myocardial contractility did not deteriorate, and the systemic vascular tension was improved after Esmolol reducing the HR of SIC patients. The application of Esmolol in SIC patients did reduce their short-term mortality, thought it failed to reduce the mechanical ventilation time, ICU hospital stay or total hospital stay. STE does not have a threshold for SIC diagnosis, and further large-scale studies are needed for confirmation.
