1. Perioperative associates of exaggerated heart rate responses pre-exercise.
Perioperative associates of exaggerated heart rate responses pre-exercise. (A) Heart rate immediately preoperatively, at end of surgery and 30 min postextubation, stratified by exaggerated heart rate rise (EHRR). Two-way analysis of variance (operation time point×cardiopulmonary exercise testing heart rate phenotype) showed that EHRR (22/54 patients in POM-O trial) was independently associated with higher heart rates during the perioperative period (p=0.017). (B) Kaplan-Meier plot for length of hospital stay following major surgery, stratified by EHRR (n=566; p=0.03, by Gehan-Breslow-Wilcoxon survival analysis).
