BACKGROUND Patients who require hospitalization because of decompensated HF represent a group of the most seriously ill individuals who evolve with high mortality and hospital readmission rates. OBJECTIVES We sought to evaluate the current natural course of HF by analyzing mortality and readmission rates in this new era of neurohormonal blockage. (More)
OBJECTIVE To evaluate uric acid renal excretion, hyperuricemia, renal dysfunction, and prognosis in patients with decompensated severe heart failure, as there are few data available. METHODS One hundred and twenty-two patients, hospitalized for heart failure decompensation, in NYHA class IV, were classified into 3 groups as follows. Pilot group [ejection(More)
OBJECTIVE To assess whether the treatment with levosimendan is more expensive than the usual one with dobutamine, since price of medications does not usually represent the greatest expense in the treatment of cardiac decompensation. METHODS The cost of treatment of 18 inpatients with cardiac decompensation, 9 of which treated with dobutamine (dobuta(More)
OBJECTIVE To evaluate the relationship between 24-hour ambulatory arterial blood pressure monitoring and the prognosis of patients with advanced congestive heart failure. METHODS We studied 38 patients with NYHA functional class IV congestive heart failure, and analyzed left ventricular ejection fraction, diastolic diameter, and ambulatory blood pressure(More)
OBJECTIVE To study the major clinical characteristics of patients with heart failure who survived more than 24 months after hospitalization for compensation. METHODS The study comprised 126 patients with heart failure in functional class III or IV, with a mean age of 51.7 years. Most patients were men (73%), had a mean ejection fraction (EF) of 0.36 and(More)
BACKGROUND The progression of heart failure in Chagas' disease has been explained by remodeling, leading to neurohumoral activation, or by the direct parasite damage to parasympathetic neurons during acute phase, leading to early sympathetic activation and progressive heart failure. To help distinguish between these hypotheses we studied muscle sympathetic(More)
Treatment of large multinodular goiter (MNG) with radioiodine preceded by recombinant human thyrotropin (0.1 mg rhTSH) has been shown to be a safe alternative for patients with comorbidities that preclude surgery. However, the increase in serum thyroid hormones that follows both treatments may be harmful for some patients, particularly those with underlying(More)
This study investigated an endoscopic technique of harvesting the sural nerve graft. Using endoscopic instrumentation, the sural nerve was harvested from six cadaveric legs. A 2-cm longitudinal incision was made immediately posterior to the lateral malleolus, and a 5-mm endoscope was introduced. The path of the nerve was followed to the popliteal space, and(More)
