AUC indicates area under the curve; CAD, coronary artery disease; COPD, chronic obstructive pulmonary disease; DM, diabetes mellitus; eGFR, estimated glomerular filtration rate; HF, heart failure; HR, hazard ratio; LAD, left atrial dimension; SAHRE, sustained atrial high‐rate episode; TIA, transient ischemic attack; and WBC, white blood cell.
