big ET for the diagnosis of HFpEF

06/14/2018

Renal dysfunction may limit the clinical application of NT-proBNP in the diagnosis of heart failure.

Big ENDOTHELIN is an excellent biomarker candidate for the diagnosis of HFpEF in CKD, independent of GFR as recently discussed in: 

Renal function, N-terminal Pro-B-Type natriuretic peptide, propeptide big-endothelin and patients with heart failure and preserved ejection fraction.

Highlights: 

• NT-proBNP is strongly associated with GFR and shows an exponential negative correlation with GFR decline.

• Big ET-1 is much less affected by GFR decline than NT-proBNP

• A single cut-off point is sufficient in the diagnosis of HFpEF in CKD, independent of GFR
