Key result
Reduced heart rate variability was strongly associated with ischemic gastrointestinal disease and nonsurvival, with a multivariable model predicting nonsurvival yielding an AUC of 0.95 (P=0.0124).
Why the study?
Does heart rate variability differ between horses with ischemic versus nonischemic gastrointestinal disease, and is it associated with nonsurvival?
Observational (n=67)
No

McConachie et al. (2015) conducted an observational in Acute gastrointestinal disease (n=67). Ischemic gastrointestinal disease vs. Nonischemic gastrointestinal disease or elective surgery was evaluated on Heart rate variability and nonsurvival (AUC 0.95, p=0.0124). Reduced heart rate variability was strongly associated with ischemic gastrointestinal disease and nonsurvival, with a multivariable model predicting nonsurvival yielding an AUC of 0.95 (P=0.0124).
