Suspected PE carries high 1-year mortality regardless of confirmation; leaves open whether alternative diagnoses drive prognosis in non-PE cases.
Does confirmed pulmonary embolism compared to refuted pulmonary embolism affect 1-year mortality in patients with clinically suspected acute pulmonary embolism?
Patients presenting with clinically suspected pulmonary embolism have a poor 1-year prognosis regardless of whether PE is confirmed or refuted by imaging, with a non-significant trend toward higher mortality in those without PE.
