Appendix 1: Quick Reference Card. Testing for Natriuretic Peptides (NPs) involves the analysis of either BNP (EDTA plasma) or NT-proBNP (serum or plasma), by the central laboratory or through near patient testing (NPT, whole blood). NPs are most useful in supporting the diagnosis of ambulatory and acute decompensated Heart Failure (HF ...

BNP or NT-proBNP levels are useful in distinguishing heart failure (HF) from other causes of dyspnea. ... Thus, a high plasma BNP or NT-proBNP concentration does not exclude the presence of other diseases. Elevated BNP/NT-proBNP levels may be seen in right ventricular dysfunction secondary to pulmonary hypertension or embolus, in atrial ...

N-terminal proBNP (NT-proBNP) have been used to moni-tor heart failure, and elevated BNP levels have been found in patients with symptomatic idiopathic PVCs.7–9 The main stimulus for (NT-pro)BNP secretion is myocardial wall stress.9,10 Previous studies suggest that BNP may serve as a sensitive marker to detect PVC-induced increased ventricu-

In patients with high NT-proBNP baseline levels, lack of a rapid decline in NT-proBNP levels ( 250 ng/L) was linked to an adverse short-term prognosis (OR, 33.7; 95% CI, 8.2 to 138.8; P 0.001). In patients with low NT-proBNP baseline levels, a rise in NT-proBNP levels over 72 hours to 250 ng/L was also linked to an adverse 30-day prognosis

CONCLUSIONS: An NT-proBNP ≥125 pg/mL is common in females without classical cardiovascular risk factors as well as older people. If NT-proBNP becomes widely used for screening in the general population, interpretation of NT-proBNP levels will require that age and sex-specific thresholds are used to identify patients with potential ...

NT-PROBNP testing may be particularly high when the results of other tests are ambiguous. NT-PROBNP concentrations are highest in dogs with active heart failure. Apparent false positives: there are a number of conditions that can lead to elevations in NT-proBNP that are not associated with an abnormal echocardiogram. NT-proBNP is …

In patients with end-stage renal disease, NT-proBNP values >12’200 pg/ml were associated with a 314 days mortality of 68%, three times higher than levels <12’200 pg/ml [22]. Hence, elevated (NT-pro) BNP levels might be useful to predict in-hospital mortality among a wide range of clinical conditions.

BNP and NT-proBNP assays are useful for evaluating patients with acute dyspnea, as a low level of natriuretic peptide can help rule out congestive heart failure (CHF) and reduce reliance on echocardiography. Conversely, these assays can be particularly useful in recognizing CHF in a patient with acute dyspnea and a history of chronic ...

NTproBNP ≥100 pmol/L: Abnormal. There is evidence of increased stretch and stress on the myocardium. Additional diagnostics are recommended to determine clinical significance. For cats with NTproBNP results 100 pmol/L or higher, echocardiography is recommended for the diagnosis and management of heart disease in the cat.
