Objectives: This study was designed to investigate whether the addition of N-terminal pro–B-type natriuretic peptide–guided, intensive patient management (BM) to multidisciplinary care (MC) improves outcome in patients following hospitalization due to heart failure (HF).
Background: Patients hospitalized due to HF experience frequent rehospitalizations and high mortality.
Methods: Patients hospitalized due to HF were randomized to BM, MC, or usual care (UC). Multidisciplinary care included 2 consultations from an HF specialist who provided therapeutic recommendations and home care by a specialized HF nurse. In addition, BM included intensified up-titration of medication by HF specialists in high-risk patients. NT-proBNP was used to define the level of risk and to monitor wall stress. This monitoring allowed for anticipation of cardiac decompensation and adjustment of medication in advance.
Results: A total of 278 patients were randomized in 8 Viennese hospitals. After 12 months, the BM group had the highest proportion of antineurohormonal triple-therapy (difference among all groups). Accordingly, BM reduced days of HF hospitalization (488 days) compared with the hospitalization for the MC (1,254 days) and UC (1,588 days) groups (p < 0.0001; significant differences among all groups). Using Kaplan-Meier analysis, the first HF rehospitalization (28%) was lower in the BM versus MC groups (40%; p = 0.06) and the MC versus UC groups (61%; p = 0.01). Moreover, the combined end point of death or HF rehospitalization was lower in the BM (37%) than in the MC group (50%; p < 0.05) and in the MC than in the UC group (65%; p = 0.04). Death rate was similar between the BM (22%) and MC groups (22%), but was lower compared with the UC group (39%; vs. BM: p < 0.02; vs. MC: p < 0.02).
Conclusions: Compared with MC alone, additional BM improves clinical outcome in patients after HF hospitalization.
