Parameter for evaluation of kidney function in patients evaluated for heart transplantation. eGFR: estimated glomerular filtration rate. CKDEPI: Chronic Kidney Disease Epidemiology Collaboration, eGFR: estimated Glomerular Filtration Rate.

Parameter	Note
Intrinsic renal disease	The presence of hypertension, diabetes mellitus, or lupus increases the possibility of irreversible kidney disease.
eGFR	Perform two independent measurements for eGFR at least two weeks apart with the CKD-EPI formula.
Proteinuria	Proteinuria is indicative of intrinsic kidney damage.
Kidney size and parenchymal evaluation	The shrunken size of the kidney and the presence of cortical scarring indicate long-term intrinsic and irreversible kidney disease.
Improved kidney function after hemodynamic optimizations	Increased eGFR after the use of inotropes/vasodilators/diuretics is indicative of functional kidney dysfunction.
