: D-dimer testing is highly sensitive for ruling out PE in low-to-intermediate risk patients. Cardiac biomarkers like Troponin and BNP help assess myocardial injury and RV strain.
: Roughly 70% to 80% of emboli arise from proximal deep veins in the legs or pelvis. Download Embolie pulmonaire aiguГ« pdf
: Tools such as the Wells Score or Geneva Score assess pre-test probability. The PERC (Pulmonary Embolism Rule-out Criteria) is used to safely exclude PE in low-risk patients without further testing. : D-dimer testing is highly sensitive for ruling
: The mainstay for most patients. Low-molecular-weight heparin (LMWH) is often preferred over unfractionated heparin (UFH) for initial treatment. Long-term management typically involves Direct Oral Anticoagulants (DOACs) like apixaban or rivaroxaban. : Tools such as the Wells Score or
: Once a clot lodges in the pulmonary vascular bed, it increases pulmonary vascular resistance, which can lead to acute right ventricular (RV) failure and hemodynamic collapse.
