Obstructive sleep apnea is associated with worse clinical-radiological risk scores of pulmonary embolism. J Sleep Res. 2019 Jun 10;:e12871 Authors: Toledo-Pons N, Alonso-Fernández A, de la Peña M, Pierola J, Barceló A, Fernández-Capitán C, Lorenzo A, Mejía Núñez JA, Carrera M, Soriano JB, Calvo N, Pinilla I, García-Río F Abstract Obstructive sleep apnea is a risk factor for pulmonary embolism, although its association with pulmonary embolism severity is unknown. Our objective was to study if obstructive sleep apnea is associated with worse pulmonary embolism severity scores and greater extent of arterial obstruction. In consecutive pulmonary embolism patients, we performed respiratory polygraphy and recorded sleep characteristics, classical risk factors for pulmonary embolism and physical activity 6-12 months after the pulmonary embolism episode. Simplified Geneva Prognostic Score and Pulmonary Embolism Severity Index were calculated at the time of the pulmonary embolism diagnosis. The Pulmonary Artery Obstruction Index and the right ventricle to left ventricle diameter ratio were measured by computed tomography pulmonary angiography. We included 120 patients, of whom 45.8% had moderate-severe obstructive sleep apnea (apnea-hypopnea index > 15 hr-1 ). There was a larger proportion of moderate-severe obstructive sleep apnea patients in the third and fourth Pulmonary Artery Obstruction Index quartiles and in the III-...
