Final answer:
The eGFR cutoff to reduce the risk of CV death and HHF in adults with HF is a glomerular filtration rate (GFR) of less than 15 mL/min/1.73 m².
Step-by-step explanation:
The eGFR cutoff to reduce the risk of CV death and HHF in adults with HF is a glomerular filtration rate (GFR) of less than 15 mL/min/1.73 m². This level of GFR indicates established kidney failure. Individuals with a GFR below this cutoff are classified as having stage 5 chronic kidney disease (CKD) and are at higher risk for cardiovascular death and heart failure hospitalization.
