Abstract
from the results, it could be concluded that we observed relatively higher incidence of CTEPH following acute PE. It was demonstrated that female gender, persistent dyspnea especially NYHA class 4, delayed presentation at PE diagnosis, hypothyroidism, history of malignancy, recurrent VTE, central PE, high D.dimer, increased RV/LV ratio in CT pulmonary angiography, high sPAP, low TAPSE, RV dysfunction and TR were all considered risk factors associated with developing CTEPH following an episode of PE.
