Background: Patients admitted for decompensated heart failure (HF) receive intensive diuretic and vasodilator therapy in the first days. Normally, this is a successful approach that leads to HF compensation and hospital discharge. However, recurrences within the first week of discharge are common.Objective: to evaluate whether the main predictor of recurrent outcomes in patients with HF is the severity of decompensation at admission or patient's blood volume after clinical management.Methods: Prospective, cohort study of patients admitted between January 2013 and October 2014, with diagnosis of acute decompensated HF, who were followed-up for 60 days after discharge. Inclusion criterion was increased plasma NT-proBNP (> 450 pg/mL for patients younger than 50 years or > 900 pg/mL for patients older than 50 years). Primary outcome was the combination of cardiovascular death with rehospitalization for decompensated HF in 60 days.Results: Ninety patients were studied, with median NT-proBNP at admission of 3,947pg/mL (IQR: 2,370 -7,000 pg/mL), and median NT-proBNP at discharge of 1,946pg/mL (IQR: 1,000 -3,781 pg/mL). The incidence of combined outcome was 30% (12.2% of deaths and 20% of rehospitalization). The area under the ROC curve for NT-proBNP at admission and 60-day cardiovascular events was 0.49 (p = 0.89; 95% CI = 0.36 -0.62). The area under the curve of NT-proBNP absolute variation for 60 day-events was 0.65 (p = 0.04; 95%CI = 0.51 -0.79), and the area under the curve for NT-BNP at discharge was 0.69 (p = 0.03; 95%CI = 0.58 -0.80). In the multivariate analysis, pre-discharge NT-proBNP was a predictor of the primary outcome, independently of the NT-proBNP at admission and other risk factors. Conclusion:Different from the severity of decompensation at hospitalization, blood volume after compensation of HF is associated with recurrent event. This finding suggests that, regardless of initial severity, therapy response during hospitalization is determinant of the risk of recurrent decompensation.

Background: Hemorrhagic events in Acute Coronary Syndromes (ACS) have been independently associated with death in international multicenter registries. However, that association has not been tested in Brazil and the true causal relationship between bleeding and death has not been completely shown.
