Heart Rate Variability Markers as Correlates of Survival in Recipients of Hematopoietic Cell Transplantation

Abstract

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. 
. Data were derived from a sample of 27 English-speaking patients undergoing allogeneic or autologous HCT at Stanford University. 
. 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.
. An increased probability of survival was significantly related to increases in two HRV indexes. 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.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
