    The article discusses the identification of normotensive shock in acute pulmonary embolism using a multi-parametric diagnostic framework.

  • 2

    A reduced TAPSE/PASP ratio is independently associated with 30-day mortality in patients with acute pulmonary embolism.

  • 3

    The Venous Excess Ultrasound Score (VExUS) correlates with disease severity in acute pulmonary embolism and aids in risk stratification.

  • 4

    Inadequate tricuspid regurgitation velocity (TRV) limits the use of TAPSE/PASP, necessitating alternative metrics for assessing right ventricular function.

  • 5

    A VExUS score > 1 shows excellent diagnostic accuracy for identifying high-risk pulmonary embolism, with high sensitivity and specificity.
