Exercise-induced pulmonary arterial hypertension.
BACKGROUND The clinical relevance of exercise-induced pulmonary arterial hypertension (PAH) is uncertain, and its existence has never been well studied by direct measurements of central hemodynamics. Using invasive cardiopulmonary exercise testing, we hypothesized that exercise-induced PAH represents a symptomatic stage of PAH, physiologically intermediate between resting pulmonary arterial hyp...
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...
متن کاملExercise Intolerance in Pulmonary Arterial Hypertension
Pulmonary arterial hypertension (PAH) is associated with symptoms of dyspnea and fatigue, which contribute to exercise limitation. The origins and significance of dyspnea and fatigue in PAH are not completely understood. This has created uncertainly among healthcare professionals regarding acceptable levels of these symptoms, on exertion, for patients with PAH. Dysfunction of the right ventricl...
متن کاملExercise-induced pulmonary hypertension: at last!
Stress tests are for the identification of silent pathology. Applications to medical diagnosis are numerous. For example, ventilation (V′E) and mean pulmonary artery pressure (mPAP) may overlap at rest, but markedly diverge during exercise in patients with pulmonary hypertension or heart failure and in healthy controls (figure 1). Accordingly, measurements of mPAP during exercise have been part...
متن کاملCriteria for diagnosis of exercise pulmonary hypertension.
The previous definition of exercise pulmonary hypertension (PH) with a mean pulmonary artery pressure (mPAP) >30 mmHg was abandoned because healthy individuals can exceed this threshold at high cardiac output (CO). We hypothesised that incorporating assessment of the pressure-flow relationship using the mPAP/CO ratio, i.e. total pulmonary resistance (TPR), might enhance the accuracy of diagnosi...
