DIAZ, Gabriel F. Pulmonary hypertension at moderate altitude in children. Rev. Colomb. Cardiol. [online]. 2012, vol.19, n.4, pp.199-207. ISSN 0120-5633.

We report the lack of studies on the relationship between pulmonary hypertension and altitude above sea level in children, and based on the physiology of the latter we emphasize the importance of hypobaric hypoxia, which plays a determinant role in the etiology and bio-pathogenesis of pulmonary hypertension of the altitude inhabitants. Regarding the bio-pathogenesis, we indicate the importance of the hyper-reactivity of the pulmonary vascular bed and its correct evaluation. Similarly, we make a summary of pathologies related to pulmonary hypertension in the child living in the altitude, and finally, with respect to the treatment of pulmonary hypertension of the altitude inhabitants, we highlight through the evolution of clinical cases the importance of living at low altitude above sea level.
