Preoperative Resting Heart Rate and 30-Day Heart Failure After Off-Pump Coronary Artery Bypass Grafting
Listen to this summary
The authors investigate the relationship between preoperative resting heart rate (RHR) and the incidence of 30-day heart failure following off-pump coronary artery bypass grafting in older adults. They find that higher preoperative RHR, particularly above 80 beats per minute, is significantly associated with an increased risk of heart failure, and suggest that intraoperative heart rate patterns may mediate this relationship. This study highlights the potential of preoperative RHR as a practical marker for predicting postoperative heart failure risk.
