Snoring and the risk of obstructive sleep apnea in patients with pulmonary embolism.

ABSTRACT:

Background

Obstructive sleep apnea (OSA) is associated with prothrombotic effects that could lead to venous thromboembolic disease. We performed a prospective cross-sectional study to determine the prevalence of snoring and risk of OSA in patients with acute pulmonary embolism (PE).

Methods

We evaluated 270 consecutive patients who underwent a computed tomographic angiogram for suspected PE. Patients without PE served as a control group. Demographic and clinical characteristics were analyzed. The Berlin Questionnaire was used to determine the presence of snoring and the risk of OSA. A subset of patients also underwent formal nocturnal polysomnography.

Results

PE was present in 71 (26%) of the 270 patients who underwent a computed tomographic angiogram. When compared w
