Low-grade and high-grade fever at presentation of acute pulmonary embolism

Blood Coagul Fibrinolysis. 2004 Jun;15(4):331-3. doi: 10.1097/00001721-200406000-00007.


We retrospectively reviewed the medical records of 154 consecutive patients with acute pulmonary embolism (PE) admitted to an Internal Medicine Service. At presentation, fever (temperature > 37 degrees C) without other identified causes was present in 28 patients (18.2%): 27 patients had low-grade fever (temperature 37-39 degrees C) and one patient had high-grade fever (temperature > 39 degrees C). Epidemiological and clinical characteristics, electrocardiographic and chest radiograph abnormalities and mortality rate were similar in patients with and without fever. Fever, including high-grade fever, is a possible presenting feature in patients with acute PE. Patients with acute PE and fever have similar characteristics compared with those without fever.
