Evaluation 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 کاملThe accuracy of FEF25-75/ FVC for primary classification of the pulmonary function test
Introduction: The forced expiratory flow at 25 and 75% of the pulmonary volume/forced vital capacity ratio (FEF25-75/FVC) as a spirometry parameter has been successful in the early diagnosis of chronic obstructive pulmonary disease (COPD) and the methacholine challenge test for assessing airway responsiveness.To determine the accuracy of FEF25-7...
متن کاملPulmonary arterial hypertension in scleroderma: care gaps in screening
One in six patients with systemic sclerosis will develop pulmonary arterial hypertension (PAH). Screening with echocardiography and possibly pulmonary function testing (to determine the diffusing capacity of carbon monoxide) is recommended to detect PAH at a less severe stage. However, real-world screening programs have problems. Registries where echocardiograms are to be performed annually sho...
متن کاملA urinary test for pulmonary arterial hypertension?
have fewer neutrophils sequestered in the pulmonary circulation, but more neutrophils in the airspaces than wild-type mice after cecal ligation and puncture (16). High Vt ventilation can induce iNOS expression and activity in the airspace, and reactive nitrogen species contribute to impaired alveolar epithelial fluid transport and pulmonary edema in VILI (17). The mechanisms of cLT-mediated lun...
متن کاملpulmonary function test and impulse oscillometry in severe chronic obstructive pulmonary disease patients' offspring
background: several studies have showed an increased prevalence of airflow obstruction in first degree relatives of individuals with chronic obstructive pulmonary disease (copd). considering no specific research had evaluated airway resistance in offspring of patients with severe copd, we utilized a spirometry and a impulse oscillometry (io) to evaluate this population. materials and methods: i...
