Association of Shock Index and Variants with Mortality in Acute Pulmonary Embolism

The authors aimed to evaluate the association between early emergency department measurements of the shock index (SI) and its variants with 30-day mortality in patients diagnosed with acute pulmonary embolism (PE). Their findings indicated that the age-adjusted SI demonstrated the highest discriminatory efficiency for predicting mortality compared to other SI variants and established risk stratification tools. The study suggests the need for further research on the age-adjusted SI's potential role in improving prognostication and management of acute PE.
