Pulmonary embolism (PE) is a significant clinical condition requiring rapid diagnosis, with high mortality and morbidity, in patients presenting to the emergency department with shortness of breath. The chronic presence of dyspnea, particularly in individuals with chronic obstructive pulmonary disease (COPD), chronic heart failure, pulmonary hypertension, and similar cardiopulmonary diseases, makes it difficult to differentiate PE in the acute phase. In this patient group, pulmonary artery pressure (PAP) values measured by echocardiography can provide important clinical information in the diagnostic process. The aim of this study is to determine the usability of echocardiographic PAP changes obtained from emergency department records in the early risk stratification of pulmonary embolism.
