Elevated preoperative HR >87 bpm may flag subclinical impairment; leaves open whether it warrants targeted preoperative evaluation.
Is elevated preoperative heart rate > 87 beats min-1 associated with markers of subclinical cardiac failure in surgical patients aged ≥45 yr?
Elevated preoperative heart rate (>87 bpm) in surgical patients is associated with impaired cardiopulmonary performance, suggesting clinically unsuspected subclinical cardiac failure.
