Pulmonary embolism (PE) is a leading cause of cardiovascular morbidity and mortality, with 10–30 % of patients dying within one month of diagnosis [1]. Early risk stratification can aid clinicians in determining the appropriate intensity of treatment and monitoring needed post-discharge [2]. The Pulmonary Embolism Severity Index (PESI) and its simplified version (sPESI) are widely validated tools for estimating 30-day mortality in acute PE [3]. The sPESI score, based on six accessible clinical variables, offers a streamlined alternative with similar prognostic value and is incorporated into international guidelines [2].
