Heart rate variability analysis is a novel tool that may detect autonomic instability and predict post-operative complications in adult cardiac surgery.
Does heart rate variability analysis predict complications in adult patients undergoing cardiac surgery?
HRV analysis shows promise as a tool to detect autonomic instability and predict complications after adult cardiac surgery, though larger studies are needed for routine clinical implementation.
Heart rate variability (HRV) refers to the variations between consecutive heartbeats, which depend on the continuous modulation of the sympathetic and parasympathetic branches of the autonomic nervous system. HRV has been shown to be effective as a predictor of risk after myocardial infarction and an early warning sign of diabetic neuropathy, and in the cardiology setting is now recognized to be a useful tool for risk-stratification after hospital admission and after discharge. Recent evidences suggest that HRV analysis might predict complications even in patients undergoing cardiac surgery, and the present review summarizes the importance of HRV analysis in adult cardiac surgery and the perspectives for HRV use in current clinical practice. Although future larger studies are warranted before HRV can be included into daily clinical practice in adult cardiac surgery, HRV is a novel tool which might detect autonomic instability in the early postoperative phase and during hospital stay, thus predicting or prompt-diagnosing many of the post-operative complications.
Nenna et al. (Wed,) conducted a review in Adult cardiac surgery. Heart rate variability (HRV) analysis was evaluated on Post-operative complications. Heart rate variability analysis is a novel tool that may detect autonomic instability and predict post-operative complications in adult cardiac surgery.
