Table 2. Blood test results at hospital admission, in the ICU (POD1), and in the general ward (POD9).

Cardiac troponin I and brain natriuretic peptide were elevated upon arrival, indicating cardiac stress. AST and ALT were also elevated due to hepatic congestion. Cr and eGFR reflected impaired renal function. AST and ALT peaked on POD2 and gradually declined thereafter. Cr and eGFR also showed improvement after POD2. By POD9, most blood test values had returned to near-normal levels.

ALT, alanine aminotransferase; AST, aspartate aminotransferase; Cr, creatinine; eGFR, estimated glomerular filtration rate; POD1, postoperative day 1; POD2, postoperative day 2; POD9, postoperative day 9

Test	Reference range	Arrival (hospital)	ICU (POD1)	General ward (POD9)

ALT	10-42 U/L	126	385	90
Cr	0.6-1.1 mg/dL (male)	2.2	1.9	1
