Multicenter Study Comparative Study
Admission, discharge, or change in B-type natriuretic peptide and long-term outcomes: data from Organized Program to Initiate Lifesaving Treatment in Hospitalized Patients with Heart Failure (OPTIMIZE-HF) linked to Medicare claims.
B-type natriuretic peptide (BNP) has been associated with short- and long-term postdischarge prognosis among hospitalized patients with heart failure. It is unknown if admission, discharge, or change from admission to discharge BNP measure is the most important predictor of long-term outcomes. ⋯ Discharge BNP best predicts 1-year mortality and/or rehospitalization among older patients hospitalized with heart failure. Discharge BNP plus clinical variables modestly improves risk classification and model discrimination for long-term outcomes.

Multicenter Study Clinical Trial
Increased 90-day mortality in patients with acute heart failure with elevated copeptin: secondary results from the Biomarkers in Acute Heart Failure (BACH) study.
In patients with heart failure (HF), increased arginine vasopressin concentrations are associated with more severe disease, making arginine vasopressin an attractive target for therapy. However, AVP is difficult to measure due to its in vitro instability and rapid clearance. Copeptin, the C-terminal segment of preprovasopressin, is a stable and reliable surrogate biomarker for serum arginine vasopressin concentrations. ⋯ URL: http://www.clinicaltrials.gov.

Randomized Controlled Trial Multicenter Study
Relationship between reactive pulmonary hypertension and mortality in patients with acute decompensated heart failure.
In patients with heart failure, pulmonary hypertension (PH) predicts higher risk for morbidity and mortality. However, few data are available on the prognostic implications of reactive (precapillary) PH superimposed on passive (postcapillary) PH. ⋯ Reactive PH is common among patients with acute decompensated heart failure after initial diuretic and vasodilator therapy. The adverse outcome associated with PH is predominantly due to increased mortality rates in the subgroup of patients with reactive PH.
