Cardiovascular response during head-up tilt in Chronic Fatigue Syndrome (CFS)

  [ 31 votes ]   [ Discuss This Article ]
www.ProHealth.com • March 5, 1999


This study examined the cardiovascular response to orthostatic
challenge, and incidence and mechanisms of neurally mediated
hypotension in chronic fatigue syndrome (CFS) during a head-up
tilt test. Stoke volume was obtained by a thoracic impedance
cardiograph, and continuous heart rate and blood pressure were
recorded during a 45-min 70 degrees head-up tilt test.
Thirty-nine CFS patients and 31 healthy physically inactive
control subjects were studied. A positive tilt, i.e. a drop in
systolic blood pressure of > 25 mmHg, no concurrent increase
in heart rate and/or development of presyncopal symptoms, was
seen in 11 CFS patients and 12 control subjects (P > 0.05).

During baseline and the first 5 min of head-up tilt, CFS
patients had higher heart rate and smaller pulsatile-systolic
area than control subjects (P < 0.05). Among subjects who
completed the test, those with CFS had higher heart rate and
smaller stroke volume (P < 0.05) than corresponding control
subjects. When comparing those who had a positive test outcome
in each group, CFS patients had higher heart rates and lower
pulse pressure and pulsatile-systolic areas during the last 4
min before being returned to supine (P < 0.05). These data
show that there are baseline differences in the cardiovascular
profiles of CFS patients when compared with control subjects
and that this profile is maintained during head-up tilt.

However, the frequency of positive tilts and the haemodynamic
adjustments made to this orthostatic challenge are not
different between groups.
