Pre-discharge BNP levels >696 pg/ml strongly predicted 30-day re-admission or death in patients with decompensated heart failure compared to lower levels (RH 15.0; 95% CI 4.2-53.8; p<0.0001).

Do pre-discharge BNP levels predict early re-admission or death in patients admitted to a general medical unit for decompensated heart failure?
Pre-discharge BNP levels strongly predict 30-day re-admission or death in elderly, comorbid patients admitted to general medical wards for decompensated heart failure.
Effect estimate: RH 15.0 (95% CI 4.2-53.8)
Absolute Event Rate: 56% vs 4%
p-value: p=<0.0001
BACKGROUND: B-type natriuretic peptide (BNP) represents a promising predictor of early (30 days) re-admission in patients with heart failure (HF) admitted to cardiology units. Whether BNP retains its predictive value in unselected patients admitted to general medical wards is unknown. METHODS: We determined BNP levels on admission and pre-discharge in 100 consecutive patients (71 male, mean age 78+/-10 years) admitted to a general medical unit due to decompensated HF. Follow-up after discharge was 30 days. RESULTS: Of the 100 patients, 86 had >/=1 comorbid conditions. Median BNP was 739 pg/ml on admission (25th-75th percentile 355-1333 pg/ml, respectively), and 414 pg/ml pre-discharge (25th-75th percentile 220-696 pg/ml). Seventeen patients were re-admitted or died within 30 days. Patients with pre-discharge BNP values >75th percentile (696 pg/ml) had greater risk of re-hospitalisation, as compared to values 75th percentile were associated with a 15.0 independent relative hazard (RH) of early re-admission or death (95% CI 4.2-53.8; p/=III at discharge (RH 2.9; 95% CI 1.1-9.3; p<0.05). CONCLUSION: In a general medical unit, pre-discharge BNP levels were a strong independent predictor of early re-admission or death due to HF, irrespective of substantial comorbidity and advanced age.
Verdiani et al. (Sat,) conducted a cohort in Decompensated heart failure (n=100). Pre-discharge BNP >696 pg/ml (>75th percentile) vs. Pre-discharge BNP ≤696 pg/ml was evaluated on Early re-admission or death within 30 days (RH 15.0, 95% CI 4.2-53.8, p=<0.0001). Pre-discharge BNP levels >696 pg/ml strongly predicted 30-day re-admission or death in patients with decompensated heart failure compared to lower levels (RH 15.0; 95% CI 4.2-53.8; p<0.0001).
