Pulmonary Hypertension Secondary to COPD
The development of pulmonary hypertension in COPD adversely affects survival and exercise capacity and is associated with an increased risk of severe acute exacerbations. Unfortunately not all patients with COPD who meet criteria for long term oxygen therapy benefit from it. Even in those who benefit from long term oxygen therapy, such therapy may reverse the elevated pulmonary artery pressure ...
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 کاملExperimental Acute Monolobar Pulmonary Hypertension †
Necrosis, fibrinoid changes, and cellular infiltrations of pulmonary arterioles have been observed, among other alterations, in extreme pulmonary arterial hypertension. Whether these lesions are the cause or the effect of the high pressure, whether they are the consequence of spasm, or whether they are produced by some other mechanism such as hypersensitivity, remains to be established. Certain...
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...
