Association of NT-proBNP levels to LVEF, eGFR and cTnT
| NT-proBNP cut-off levels at discharge in pg/mL | ||||
|---|---|---|---|---|
| <1500 | 1500–5000 | 5001–15 000 | >15 000 | |
| LVEF <25% at admission, % (n) | 18 (57/320) | 26 (110/425) | 37 (107/287) | 40 (48/121) |
| eGFR ≤30 mL/min/1.73 m² at discharge % (n)* | 7 (22/309) | 11 (47/433) | 22 (68/315) | 40 (49/124) |
| cTnT <0.03 μg/L at admission % (n) | 59 (122/206) | 42 (116/279) | 33 (61/185) | 28 (18/64) |
| cTnT 0.03–0.05 μg/L at admission % (n) | 21 (44/206) | 20 (57/279) | 20 (36/185) | 19 (12/64) |
| cTnT >0.05 μg/L at admission % (n) | 19 (40/206) | 38 (106/279) | 48 (88/185) | 53 (34/64) |
*Estimated Glomerular Filtration Rate was calculated as 186.3×(Creatinin mg/dL)−1.154×(age)−0.203×(0.742 if female)×(1.210 if black).
cTnT, cardiac troponin T; eGFR, estimated Glomerular Filtration Rate; LVEF, left ventricle ejection fraction; NT-proBNP, N-terminal pro-B-type natriuretic peptide.
