摘要

Background and Aim: Cardiac autonomic imbalance and cognitive deficits are known to exist in chronic hematological disorders. This pilot study was done to assess and compare the cardiac autonomic activity and cognitive status of patients suffering from hemophilia with age matched healthy male volunteers. Methods: Fourteen males (18-45 years) suffering from Hemophilia and fourteen age-matched healthy male volunteers were included in test and control groups respectively. Mann-Whitney U test was done to detect the difference between the two groups with respect to blood pressure, time domain and frequency domain Heart rate variability (HRV) indices, descriptors of Poincare plot, Auditory Reaction Time (ART) and Visual Reaction Time (VRT). The level of significance was set at p<0.05. Results: There was no significant difference between the test and control groups with respect to blood pressure, HRV indices and descriptors of Poincare plot. Visual reaction time for red and green light was significantly prolonged in the Hemophiliacs. Conclusion: This pilot study did not reveal any significant alterations in the cardiac autonomic activity of people with Hemophilia. However, future studies with a larger sample size are necessary to confirm the results of the study.
