Background: Pulmonary embolism is the third commonest cause of cardiovascular death. The standard approach for diagnosis is the computed tomography pulmonary angiography. However, it has certain limitations, such as pregnancy or allergy.
Objectives: Can Echocardiographic changes namely systolic pulmonary arterial pressure and right ventricular dimension changes show relation with the extent of acute pulmonary embolism detected by CT pulmonary angiography.
Material and Method: This is analytical study conducted in Al-Sadr Teaching Hospital from July 2019 till the end of April 2020, and enrolled (31) patients with acute pulmonary embolism who attended ER or admitted to the ICU. All patients underwent echocardiography and CT pulmonary angiography.
Results: Mean age of patients was (35.74±12.05) years, and females constituted (61.29%) of them. Mean BMI was (25.61±4.63) kg/m2. There was significant correlation between right ventricle diameter/ left ventricle diameter ratio and systolic pulmonary arterial pressure, R=0.313, P-value=0.043. Systolic pulmonary arterial pressure was significantly higher in patients with central/segmental pulmonary embolism compared to sub segmental pulmonary embolism, P- value=0.013. No significant difference in systolic pulmonary arterial pressure was present between central pulmonary embolism and segmental pulmonary embolism, P-value = 0.798.
Conclusions: Systolic pulmonary arterial pressure is positively correlated with the increase in RV/LV diameter ratio, and is higher in central/segmental pulmonary embolism than in sub segmental pulmonary embolism. The echocardiography findings may aid in the diagnosis of acute pulmonary embolism by raising clinical suspicion.
