1.  Relationship between Cognitive Function, Depression/Anxiety and Functional Parameters in Patients Admitted for Congestive Heart Failure 
Cognitive impairment, anxiety and depression have been described in patients with congestive heart failure (CHF). We analyzed in-hospital CHF patients before discharge with neuropsychological tests attempting to correlate with prognostic parameters.
All subjects underwent a mini mental state examination (MMSE), geriatric depression scale (GDS), anxiety and depression scale test (HADS). We evaluated NYHA class, brain natriuretic peptide (BNP), left ventricular ejection fraction (LVEF) and non-invasive cardiac output (CO).
Three-hundred and three CHF patients (age 71.6 ys) were analysed. The mean NYHA class was 2.9±0.8, LVEF was 43.4±15.8%; BNP plasma level and CO were calculated as 579.8±688.4 pg/ml and 3.9±1.1 l/min, respectively. In 9.6% a pathological MMSE score emerged; a depression of mood in 18.2% and anxiety in 23.4% of patients were observed. A significant correlation between MMSE and age (r=0.11 p=0.001), BNP (r=0.64 p=0.03) but not between MMSE and NYHA class and LVEF was observed. GDS and HADS were inversely correlated with NYHA class (r=0.38 p=0.04) and six-minute walking test (r=0.18 p=0.01) without an association with objective parameters in CHF (BNP, LVEF and cardiac output). At multivariate analysis only MMSE and BNP are inversely correlated significantly (p=0.019 OR=-0.64, CI=-042-0.86).
in-hospital CHF patients may manifest a reduction of MMSE and important anxiety/depression disorders. The results of the study suggest that the presence of cognitive impairment in older CHF patients with higher BNP plasma level should be considered. In admitted CHF patients anxiety and depression of mood are commonly reported and influenced the perception of the severity of illness.

2.  Prognostic factors of mid-term clinical outcome in congestive heart failure patients discharged after acute decompensation 
Risk stratification in congestive heart failure (CHF) patients is based on a variety of clinical and laboratory variables. We analysed renal function, BNP, water composition, echocardiographic and functional determinations in predicting mid-term outcome in CHF patients discharged after decompensation.
Material and methods
All subjects with NYHA class II-IV were enrolled at hospital discharge. NYHA class, BNP, water body composition, non-invasive cardiac output and echocardiogram were analysed. Death, cardiac transplantation and hospital readmission for CHF were scheduled.
Two-hundred and thirty-seven (64.5% males, age 71.1±10.1) patients were discharged after obtaining normal hydration; left ventricular ejection fraction (LVEF) was 43.2±16.2%, cardiac output was 3.8±1.1 l/min and BNP at discharge resulted 401.3±501.7 pg/ml. During the 14-month follow-up 15 patients (6.3%) died, 1 (0.4%) underwent cardiac transplantation and 18 (7.6%) were readmitted for CHF (event group); in 203 (85.6%) no events were observed (no-event group). Higher NYHA class (2.1±0.7 vs. 1.9±0.4, p=0.01), BNP at discharge (750.2±527.3 pg/ml vs. 340.7±474.3 pg/ml, p=0.002) and impaired LVEF (33.7±15.7% vs. 44.5±15.8%, p=0.0001) and creatinine (1.7±0.6 vs. 1.2±0.8 mg/dl, p=0.004) were noticed in the event group. At multivariate Cox analysis LVEF (p=0.0009), plasma creatinine (p=0.006) and BNP at discharge (p=0.001) were associated with adverse mid-term outcome. Kaplan-Meier survival curves demonstrated that adding cut-off points for creatinine 1.5 mg/dl and discharged BNP of 250 pg/ml discriminated significantly prognosis (p=0.0001; log rank 21.09).
In predicting mid-term clinical prognosis in CHF patients discharged after acute decompensation, BNP at discharge ≥ 250 pg/ml added with plasma creatinine > 1.5 mg/dl are strong adverse predictors.
