Echocardiographic Assessment:
Performed within 24h of PE diagnosis Conventional parameters: TAPSE, RV FAC, RV/LV ratio, tricuspid S', PASP STE parameters: RV free wall longitudinal strain (RVFWS), global longitudinal strain (GLS) if feasible All measurements averaged over 3 cardiac cycles (sinus) or 5 (AF)
Follow-up data:
ICU/hospital LOS Need for vasopressors/mechanical ventilation In-hospital and 30-day mortality
Adults ≥18 years.
Confirmed acute PE (via CT pulmonary angiography).(4,6)
Echocardiography performed within 24 hours of diagnosis.
Pre-existing significant RV dysfunction (e.g., due to chronic pulmonary hypertension, cor pulmonale or congenital heart disease).
History of coronary artery disease.
Impaired LV systolic function, ejection fraction <50%.
Moderate to severe valvular heart disease.
patients aged more than 18 years old with confirmed pulmonary embolism
Cohort
Prospective
Not listed
Primary (main): Composite of in-hospital mortality, ICU admission >7 days, or need for mechanical circulatory/ventilatory support.
Secondary outcome: Each individual component; echocardiographic parameters as predictors.
