The baseline data from GLORIA-AF phase 2 demonstrate that in newly diagnosed nonvalvular atrial fibrillation patients, NOAC have been highly adopted into practice, becoming more frequently prescribed than VKA in Europe and North America. Worldwide, however, a large proportion of patients remain undertreated, particularly in Asia and North America.

HF remains a condition associated with high mortality and high hospital readmission rates. At the end of the first year, 44.5% of these patients had not needed to visit the ER or had died, which indicates that we should provide HF patients with the best possible care in an attempt to change the natural course of this increasingly frequent syndrome.
BackgroundHeart failure (HF) is a syndrome, whose advanced forms have a poor prognosis, which is aggravated by the presence of comorbidities.ObjectiveWe assessed the impact of infection in patients with decompensated HF admitted to a tertiary university-affiliated hospital in the city of São Paulo.MethodsThis study assessed 260 patients consecutively admitted to our unit because of decompensated HF. The presence of infection and other morbidities was assessed, as were in-hospital mortality and outcome after discharge. The chance of death was estimated by univariate logistic regression analysis of the variables studied. The significance level adopted was P < 0.05.ResultsOf the patients studied, 54.2% were of the male sex, and the mean age ± SD was 66.1 ± 12.7 years. During hospitalization, 119 patients (45.8%) had infection: 88 (33.8%) being diagnosed with pulmonary infection and 39 patients (15.0%), with urinary infection. During hospitalization, 56 patients (21.5%) died, and, after discharge, 36 patients (17.6%). During hospitalization, 26.9% of the patients with infection died vs 17% of those without infection (p = 0.05). However, after discharge, mortality was lower in the group that had infection: 11.5% vs 22.2% (p = 0.046).ConclusionsInfection is a frequent morbidity among patients with HF admitted for compensation of the condition, and those with infection show higher in-hospital mortality. However, those patients who initially had infection and survived had a better outcome after discharge.
OBJECTIVE:To identify predictors of low cardiac output and mortality in decompensated heart failure.INTRODUCTION:Introduction: Patients with decompensated heart failure have a high mortality rate, especially those patients with low cardiac output. However, this clinical presentation is uncommon, and its management is controversial.METHODS:We studied a cohort of 452 patients hospitalized with decompensated heart failure with an ejection fraction of <0.45. Patients underwent clinical‐hemodynamic assessment and Chagas disease immunoenzymatic assay. Low cardiac output was defined according to L and C clinical‐hemodynamic profiles. Multivariate analyses assessed clinical outcomes. P<0.05 was considered significant.RESULTS:The mean age was 60.1 years; 245 (54.2%) patients were >60 years, and 64.6% were men. Low cardiac output was present in 281 (63%) patients on admission. Chagas disease was the cause of heart failure in 92 (20.4%) patients who had higher B type natriuretic peptide levels (1,978.38 vs. 1,697.64 pg/mL; P = 0.015). Predictors of low cardiac output were Chagas disease (RR: 3.655, P<0.001), lower ejection fraction (RR: 2.414, P<0.001), hyponatremia (RR: 1.618, P = 0.036), and renal dysfunction (RR: 1.916, P = 0.007). Elderly patients were inversely associated with low cardiac output (RR: 0.436, P = 0.001). Predictors of mortality were Chagas disease (RR: 2.286, P<0.001), ischemic etiology (RR: 1.449, P = 0.035), and low cardiac output (RR: 1.419, P = 0.047).CONCLUSIONS:In severe decompensated heart failure, predictors of low cardiac output are Chagas disease, lower ejection fraction, hyponatremia, and renal dysfunction. Additionally, Chagas disease patients have higher B type natriuretic peptide levels and a worse prognosis independent of lower ejection fraction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
