Pulmonary hypertension in hypoventilation syndromes.
In this issue of the European Respiratory Journal, HELD et al. [2] report on 18 patients with severe pulmonary hypertension due to alveolar hypoventilation, who were markedly improved after 3 months of noninvasive bi-level positive-pressure ventilation (NIPPV). Mean pulmonary artery pressure (mPAP) and pulmonary vascular resistance (PVR) were 50 mmHg and 6–7 Wood units, respectively, at baselin...
متن کاملChronic hypoventilation syndromes and sleep-related hypoventilation.
Chronic hypoventilation affects patients with disorders on any level of the respiratory system. The generation of respiratory impulses can be impaired in congenital disorders, such as central congenital alveolar hypoventilation, in alterations of the brain stem or complex diseases like obesity hypoventilation. The translation of the impulses via spinal cord and nerves to the respiratory muscles...
متن کاملNocturnal hypoventilation - identifying & treating syndromes.
Nocturnal hypoventilation is a common feature of disorders affecting the function of the diaphragm or central respiratory drive mechanisms. The ensuing change in gas exchange is initially confined to rapid eye movement (REM) sleep, but over time buffering of the raised carbon dioxide produces a secondary depression of respiratory drive that will further reduce ventilation not only during sleep ...
متن کاملEvaluation of Pulmonary Hypertension In First Degree Relatives Of Patients With Primary Pulmonary Hypertension
Background: Pulmonary hypertension (PH) was defined for the first time in 1951 as primary pulmonary hypertension (PPH). Some studies emphasized on the role of genetics in the development of pulmonary hypertension in family members of affected patients. So, in this study we evaluated the prevalence of pulmonary hypertension in first degree family of patients with documented PPH. Methods: In thi...
متن کاملThalassemia Associated Pulmonary Hypertension
Cardiac disease is the main cause of death in both forms of thalassemia; thalassemia major (TM) and thalassemia intermedia (TI). Pulmonary hypertension (PH) is one of the cardiopulmonary morbidities with high mortality that, if not treated, may trigger right-sided heart failure and premature death. PH is defined as a mean pulmonary artery pressure of ≥25 mmHg at rest or ≥30 mmHg during exercise...
