This artificial Intelligence-powered system is designed to assess patients' future survival as well as important indicators affecting prognosis, which requires only a small number of easy-to-get clinical examination variables to complete the task.

This tool could apply especially to patients with advanced chronic heart failure and renal dysfunction.

LVEF: left ventricular ejection fraction. eGFR: glomerular filtration rate. MCHC: mean corpuscular hemoglobin concentration. CTnI: serum cardiac troponin I. SV: stroke volume. TBIL: serum total bilirubin. Cr: Serum creatinine. CKD stage: chronic kidney disease stage
