Heart failure (HF) is a major risk factor for postoperative mortality. A recent study found that veteran patients with preoperative HF had a 90-day postoperative mortality of 5.5% (95% CI, 5.3%-5.7%) compared with patients without HF, who had a mortality of 1.2% (95% CI, 1.1%-1.3%).1 The crude risk of mortality in patients with vs without HF was substantially attenuated by multivariable adjustment, a finding suggesting that a portion of the elevated mortality risk may be attributable to risk factors amenable to preoperative optimization.
