Does heart rate variability correlate with survival in patients undergoing hematopoietic cell transplantation?
Heart rate variability may serve as a useful predictor of mortality in patients undergoing hematopoietic cell transplantation.

HRV indexes may aid prognostication in HCT recipients; leaves open whether targeted interventions improve survival.
OBJECTIVES: To assess pre-/post-transplantation changes in autonomic tone, as measured by heart rate variability (HRV), among patients undergoing hematopoietic cell transplantation (HCT) and to look at those changes as they relate to post-transplantation survival rates. . SAMPLE & SETTING: Data were derived from a sample of 27 English-speaking patients undergoing allogeneic or autologous HCT at Stanford University. . METHODS & VARIABLES: A survival analysis using the Kaplan-Meier estimator was employed to explore whether increased HRV would enhance survival probabilities over time among patients undergoing HCT. . RESULTS: An increased probability of survival was significantly related to increases in two HRV indexes. IMPLICATIONS FOR NURSING: HRV may be a useful predictor of mortality among patients undergoing HCT. Interventions deliverable by nurses could be used to enhance HRV for patients identified as being at risk for early mortality.

Scheiber et al. (2018) conducted a cohort in Hematopoietic cell transplantation (n=27). Heart rate variability (HRV) was evaluated on Survival. Increases in two heart rate variability indexes were significantly related to an increased probability of survival among patients undergoing hematopoietic cell transplantation.
