Is pulmonary arterial pressure affected by allergic rhinitis with nasal obstruction?
Obstructive pathologies of the pulmonary tract may cause various levels of hypoxia. To compensate for the hypoxia, pulmonary arterial pressure and pulmonary arterial flow may increase. We investigated 35 patients with seasonal allergic rhinitis (AR) whether hypoxia caused by AR with a high level of obstruction in the airways may lead to an increased pulmonary arterial pressure. An echocardiographical evaluation was made following the determination of the symptomatic and non-symptomatic symptom scores. We found a positive correlation between the symptom scores both in the symptomatic and non-symptomatic periods, nasal obstruction scores and the mean pulmonary arterial pressures during these periods. Further studies with more cases are needed in order to determine the cardiac effects of hypoxia in AR, mainly pulmonary arterial hypertension.
