title: Valsalva maneuver as a possible risk factor for pulmonary embolism.
abstract: Valsalva maneuver has been suspected of precipitating pulmonary embolism (PE), but the association of the two variables has not been studied. The purpose of this retrospective study was to begin to investigate whether Valsalva behavior is associated with subsequent PE. The frequency of Valsalva behaviors prior to confirmed PE in 30 patients was compared to the frequency of Valsalva behaviors in 60 non-PE patients, randomly selected from patients matched with the study group for age, sex, and year of hospitalization.
