Abstract
BACKGROUND In elderly patients hospitalized for decompensated heart failure, B-type natriuretic peptide (BNP) levels at discharge and the change in BNP during hospitalization may provide different information and may need to be taken into account simultaneously to best reflect the response to therapy. The aim of this study was to determine whether the most accurate risk stratification is obtained using BNP level after stabilization on treatment, the change in BNP under optimal treatment, or a combination of both markers. METHODS This prospective cohort study included 157 consecutive patients aged >or=70 (mean, 83 years), hospitalized for decompensated heart failure. Clinical, radiologic, biologic, and ultrasonography data were collected on admission and at discharge. RESULTS The median BNP level on admission was 1,057 pg/mL, and the mean change during hospitalization was -42%. Cardiac death or readmission were independently predicted by both predischarge BNP (best threshold: >360 pg/mL, HR 3.35 [1.94-5.75]) and the change in BNP levels (best threshold: -50%, HR 2.52 [1.59-4.01]). The highest event rate was observed in patients with both a predischarge BNP >or=360 pg/mL and a decrease <50% during hospitalization (HR 5.97 [2.98-11.94] compared with patients with a predischarge BNP <360 pg/mL and a decrease >or=50%, after adjustment for potential confounders). The remaining patients constituted an intermediate risk group (HR 3.13 [1.44-6.77]). CONCLUSION Predischarge BNP and inhospital BNP change should not be interpreted independently from each other. The highest risk group includes patients with a high predischarge BNP level corresponding to more than the half of the BNP on admission. These patients would benefit from close monitoring for signs of decompensation.

Abstract
Congestive heart failure (CHF) is the main cause of acute dyspnea in patients presented to an emergency department (ED), and it is associated with high morbidity and mortality. B-type natriuretic peptide (BNP) is a polypeptide, released by ventricular myocytes directly proportional to wall tension, for lowering renin-angiotensin-aldosterone activation. For diagnosing CHF, both BNP and the biologically inactive NT-proBNP have similar accuracy. Threshold values are higher in elderly population, and in patients with renal dysfunction. They might have also a prognostic value. Studies demonstrated that the use of BNP or NT-proBNP in dyspneic patients early in the ED reduced the time to discharge, total treatment cost. BNP and NT-proBNP should be available in every ED 24 hours a day, because literature strongly suggests the beneficial impact of an early appropriate diagnosis and treatment in dyspneic patients. Etiologic diagnosis of febrile patients who present to an ED is complex and sometimes difficult. However, new evidence showed that there are interventions (including early appropriate antibiotics), which could reduce mortality rate in patients with sepsis. For diagnosing sepsis, procalcitonin (PCT) is more accurate than C-reactive protein. Thus, because of its excellent specificity and positive predictive value, an elevated PCT concentration (higher than 0.5 ng/mL) indicates ongoing and potentially severe systemic infection, which needs early antibiotics (e.g. meningitis). In lower respiratory tract infections, CAP or COPD exacerbation, PCT guidance reduced total antibiotic exposure and/or antibiotic treatment duration.

Abstract
BACKGROUND NT-proBNP is useful for heart failure (HF) diagnosis and prognosis. We examined the value of serial NT-proBNP monitoring to predict outcomes in decompensated HF patients attending a structured HF clinic. METHODS Patients with decompensation of established optimally treated HF, not requiring emergency hospital admission, were enrolled in the study. Patients received intensive follow-up weekly during 4 weeks and at 3 months in specialist HF clinics. Serial NT-proBNP concentrations were measured at each visit. Primary endpoint was cardiovascular death and hospital admission for HF at 3 months. RESULTS Fifty-nine patients were enrolled (60+/-14 years, LVEF 27+/-9%) and 39% had a primary endpoint during follow-up. Baseline NT-proBNP concentration (in ng/L) was 7050+/-6620, and did not differ significantly in patients with and without events (p=0.22). Patients without events showed marked NT-proBNP reduction at week-1 (30% reduction), week-2 (36% reduction), week-3 (34% reduction) and week-4 (37% reduction). By contrast, patients with events showed no significant NT-proBNP reduction during follow-up. Using a general linear model, the relative NT-proBNP reductions (%) at weeks 1-4 were predictors of adverse events (p=0.004, p<0.001, p=0.001 and p=0.03, respectively). In a stepwise multiple Cox regression analysis, NT-proBNP relative reduction (in %) at week 2 was a strong predictor of no events during follow-up (OR 0.79, 95% CI 0.70-0.88, p<0.001). CONCLUSIONS Serial NT-proBNP monitoring in decompensated HF patients seen in a structured in-hospital HF clinic predicts cardiovascular events during follow-up. NT-proBNP may be useful in an outpatient basis to identify patients at high risk needing more aggressive therapy.

Abstract
AIMS Brain natriuretic peptide (BNP), NT-proBNP and troponins are useful for the assessment of patients with heart failure. Few data exist about their serial changes and their prognostic value in patients with acute heart failure (AHF). METHODS AND RESULTS NT-proBNP and troponin-T plasma levels were measured at baseline, after 6, 12, 24, 48 h and at discharge in 116 consecutive patients with AHF and no evidence of acute coronary syndrome. NT-proBNP levels were 4421 pg/mL at baseline, declined after 24 h and reached their nadir at 48 h (2703 pg/mL). Troponin-T was detectable in 48% of patients. During a median follow-up of 184 days, 52 patients died or had a non-fatal cardiovascular hospitalisation. At a multivariable analysis including clinical and echo-Doppler variables, NT-proBNP plasma levels at discharge, detectable troponin-T plasma levels, and NYHA class at discharge were the only independent prognostic factors. CONCLUSION In patients with AHF, NT-proBNP levels decline 24 h after the initiation of intravenous therapy and troponin-T is detectable in 48% of cases. NT-proBNP levels at discharge, detectable troponin-T levels, NYHA class and serum sodium have independent prognostic value.

Abstract
BACKGROUND Amino-terminal pro-brain natriuretic peptide (NT-proBNP) is a valuable diagnostic and prognostic test in heart failure (HF). Limited information is available concerning its use in patients with renal failure, in whom dependence on renal clearance may negatively affect its performance. METHODS AND RESULTS We evaluated influence of renal function on NT-proBNP levels and on its prognostic value after hospital discharge in 283 acute HF patients. Admission and discharge NT-proBNP levels were higher in patients with decreased estimated glomerular filtration rate (eGFR). In these patients discharge NT-proBNP above median was associated to occurrence of death or readmission at 6 months (hazard ratio [HR] 2.53, 95% confidence interval [CI] 1.27-5.03); in patients with normal eGFR, a trend to this association was found (HR 1.64, CI 0.98-2.76). Decrease in NT-proBNP less than 30% of baseline was associated to outcome in patients with normal eGFR (HR 2.68, CI 1.54-4.68) and decreased eGFR (HR 2.54, CI 1.49-4.33). CONCLUSIONS Acute HF patients with renal failure have higher NT-proBNP levels than those with normal renal function. Discharge NT-proBNP has long-term prognostic value in HF patients with renal dysfunction. NT-proBNP variations during hospitalization provide additional prognostic information either in patients with normal or reduced eGFR.

Comparison of prognostic significance of amino-terminal pro-brain natriuretic Peptide versus blood urea nitrogen for predicting events in patients hospitalized for heart failure. Am J Cardiol 2007; 99:1143-5.

Abstract
N-terminal pro-brain natriuretic peptide (NT-pro-BNP) and blood urea nitrogen (BUN) predict outcomes in patients with heart failure (HF). However, it is unknown whether NT-pro-BNP is a better prognostic marker than BUN in patients hospitalized with HF. Chart reviews were performed on 257 consecutively hospitalized patients with HF whose NT-pro-BNP levels were drawn at the time of admission. The ability of NT-pro-BNP and BUN to predict the primary end point (death or readmission <30 days after discharge) was determined. Seventy-three patients (28%) reached the primary end point. Patients who reached the primary end point had significantly higher NT-pro-BNP and BUN levels. On multivariate regression analysis, the predictive values of BUN and NT-pro-BNP were very similar: the hazard ratio for NT-pro-BNP greater than the median was 1.81 (p = 0.044), and the hazard ratio for BUN greater than the median was 1.83 (p = 0.039). Analysis of the associations between NT-pro-BNP, BUN, and 30-day death or readmission as end points showed that BUN is a better predictor of outcomes (hazard ratio 3.15, p = 0.012) than NT-pro-BNP (hazard ratio 1.44, p = 0.399). In conclusion, in patients admitted to hospitals with HF, BUN is at least an equal prognosticator of HF rehospitalization or death as NT-pro-BNP. BUN outperforms NT-pro-BNP in predicting mortality in patients with advanced HF. If admitting physicians are confident that the diagnosis of HF is correct, then admission NT-pro-BNP adds little to clinical management.
