Filter by:The Eisenmenger syndrome corresponds to the most advanced form of pulmonary arterial hypertension associated with congenital heart disease. The syndrome causes chronic hypoxemia, with an increase in erythrocyte mass, which predisposes to thrombotic complications. Pentoxifylline is a xanthine derivative and it is considered as a hemorrheological agent with described effects of reduction in erythrocyte and platelet aggregation, adhesion and activation of leukocytes, and endothelial damage. The main objective of this study is to verify if the chronic oral administration of pentoxifylline to Eisenmenger patients induces an increase in the circulating levels of thrombomodulin, a naturally occurring proteoglycan with anticoagulant, anti thrombotic and anti-inflammatory properties.
The purpose of this study is to verify the applicability Six minutes walk test and Shuttle walk test in assessing functional capacity in patients with Eisenmenger Syndrome. Patients will undergo three functional tests, being the six-minute walk test, shuttle walk test and cardiopulmonary exercise test on a cycle ergometer, associated with evaluation of metabolic and ventilatory variables and cardiac monitoring throughout the test.
Due to vasodilatory properties of the NO, one of the therapeutic approaches for IPAH is oral use of nitric oxide precursors (10). Efficacy of L-arginine is well-documented in the current literature but there is paucity of data with regard to L-citrulline- malate. Hence, this study will evaluate therapeutic efficacy of L-citrulline- malate in two categories of patients with pulmonary hypertension (IPAH, and Eisenmeger syndrome). This randomized clinical trial utilizes 6-minute walk, pro BNP levels and the echocardiographic indexes an indicator of functional improvement of the patients.
The purpose of this study is to investigate the influence of physical training on exercise capacity, quality of life, functional class, oxygen consumption and right ventricular function in patients with severe associated pulmonary arterial hypertension (APAH) as part of a congenital heart defect with / without Eisenmenger's Syndrome
