Autonomic Nervous System Pretransplant Malfunction is a Powerful Predictor of Survival after Allogeneic Hematopoietic Cell Transplantation.

Background: Autonomic nervous system function indexed by heart rate variability (HRV) has shown prognostic value for mortality in various cardiovascular and noncardiovascular diseases including cancer. The purpose of this study was to evaluate an association between HRV and outcomes of allogeneic hematopoietic cell transplantation (allo-HCT) Methods: We prospectively measured HRV as a surrogate pretransplant marker of autonomic nervous system activity in consecutive allo-HCTs with hematological diseases. Results: We analyzed 112 allo-HCTs performed between July 2011 and July 2013 in our center. Univariate analysis showed that increased values of HRV components (low-frequency and high-frequency spectral component (LF and HF), standard deviation of NN interval (SDNN), and squares of the differences between adjacent normal-to-normal RR intervals (r-MSSD) were significantly associated with decreased probability of overall mortality (OM) (hazard ratio: 0.3 for LF, p
