CFS, Clinical Frailty Scale.

Adjusted variables were as follows: age; sex; body mass index; left ventricular ejection fraction; current smoking status; a history of heart failure (whether or not a de novo case), diabetes, and chronic obstructive pulmonary disease; systolic blood pressure; haemoglobin; estimated glomerular filtration rate; prescription of angiotensin‐converting enzyme inhibitor or angiotensin receptor blocker, beta‐blocker, and mineralocorticoid receptor antagonist; and New York Heart Association Class III/IV at discharge.
