Recent cardiovascular procedures, preoperative shock status, thrombocytopenia (platelets < 100,000/uL), hypoalbuminemia (serum albumin < 2.8 g/dL), elevated serum ALT (≥ 100 U/L), and elevated serum creatinine (≥ 2.0 mg/dL) had significant impacts on 30-day mortality. The gene discussed is GPT; the disease is Hypoalbuminemia.
