PG - 445-51 AB - BACKGROUND: Whether brain natriuretic peptide (BNP) combined with cardiopulmonary exercise test (CPx) and echocardiographic findings improves prognostic stratification in mild-to-moderate systolic heart failure (HF) is unclear. METHODS AND RESULTS: A total of 244 consecutive stable outpatients, median age of 71 (62-76) years, with New York Heart Association (NYHA) Class I-III HF and left ventricular ejection fraction (LVEF) < 45% underwent BNP measurement, Doppler echocardiography, and a maximal CPx. Median BNP was 166 (70-403) pg/mL, median LVEF 35% (28%-40%). A restrictive filling pattern (RFP) was present in 44 patients (18%). At CPx, peak oxygen uptake was 12 (9.7, 14.4) mL/kg/min and an enhanced ventilatory response to exercise (EVR, slope of the ventilation to CO2 production ratio, > or = 35) was found in 90 patients (37%) During 18 (9-37) follow-up months, 80 patients died or were admitted for worsening HF (33%). In addition to simple bedside clinical variables (NYHA Class III, creatinine clearance, hemoglobin), BNP levels were predictive of outcome (HR 1.35 [1.12-1.63]). However, both RFP (HR 3.36 [2.09-5.41]) and a steeper minute ventilation-carbon dioxide output slope (HR 1.50 [1.19-1.88]) outperformed BNP as prognostic markers. Patients with both RFP and EVR had a 7.30 (95% CI 4.02-13.25) HR for death or HF-admission versus subjects with neither predictor. CONCLUSIONS: This study highlights the importance of a multiparametric approach for optimal risk stratification in the elderly with mild-to-moderate HF. Patients at high risk should undergo closer follow-up and be carefully evaluated for different therapeutic options, including nonpharmacologic treatment.
