Their suggestion was based on the absence of the expected positive correlation between serum leptin levels and the BMI, and the loss of the sex-dependent difference in leptin levels, which are higher in women. Although subsequent studies did not confirm(More)
Primary abnormalities of the autonomic nervous system had been postulated as the pathogenic mechanisms of myocardial damage, in patients with Chagas disease. However, recent investigations indicate that these abnormalities are secondary and amenable to treatment with beta-adrenergic blockers. Moreover, muscarinic cardiac autoantibodies appear to enhance(More)
Beta blockers are contraindicated in patients with acutely decompensated heart failure. Current therapeutic strategies increase morbidity and mortality. We have compared the effects of frequent doses of diuretics vs a single dose of diuretics and cautious uptitration of carvedilol. Our results indicate that, although clinical compensation is achieved with(More)
