Autonomic dysfunction and beta blocker therapy in Chagas heart disease
In a hamster model of Chagas disease, Pimentel et al. (1) recently found that 1) carvedilol decreased mortality in the acute, but not in the chronic stage and 2) in the chronic stage, carvedilol neither changed the left ventricular diameter and/or function, nor attenuated changes in the resting electrocardiogram (ECG), nor decreased the myocardial collagen content. In contrast, we did not obser...
متن کاملNew advances in beta-blocker therapy in heart failure
The use of β-blockers (BB) in heart failure (HF) has been considered a contradiction for many years. Considering HF simply as a state of inadequate systolic function, BB were contraindicated because of their negative effects on myocardial contractility. Nevertheless, evidence collected in the past years have suggested that additional mechanisms, such as compensatory neuro-humoral hyperactivatio...
متن کامل[Venous endothelial dysfunction in Chagas' disease patients without heart failure].
OBJECTIVE To analyze the venous endothelial function in Chagas' disease patients without heart failure. METHODS The Chagas' disease Group (G1) was composed by 14 women and 2 men aged 46 +/- 2.7 and the Control Group (G0) by 7 women and 1 man matched by age, weight and height. Dorsal Hand Vein Compliance Technique was used to evaluate the venous endothelial function. Crescent doses of phenylep...
متن کاملAutonomic Dysfunction in Heart Failure and Renal Disease
In the methods paper presented by Reulecke et al. (2012), autonomic function is examined in healthy preterm neonates, applying HRV to cardiorespiratory data using non-linear methods. Reference HRV data is currently only available for adults (Taskforce, 1996), but through a complex series of analyses, Reulecke et al. (2012) show that while the relationship between heart rate and respiration in p...
