|Advanced age, male|
|Advanced cancer stage, history of arterial hypertension, history of paroxysmal atrial fibrillation, physical status, post-operative tachycardia|
|Increased natriuretic peptides (NT-proBNP, BNP), ectopic beats on electrocardiogram, mitral E/e′ ratio >8, low heart rate variability, low mean heart rate|
|Increased duration of surgery, surgical complications, need for post-operative blood transfusion, extended lung resection in lung cancer, use of colon conduit in esophagectomy|
Based on information from multiple studies (8–11,14,16,18,50,65,66).
BNP = B-type natriuretic peptide; NT-proBNP = N-terminal pro–B-type natriuretic peptide.
