Central Systolic Blood Pressure

Post-exertional malaise (PEM) is regarded as the hallmark symptom in chronic fatigue syndrome (CFS). The aim of the current study is to explore differences in CFS patients with and without PEM in indicators of aortic stiffness, autonomic nervous system function, and severity of fatigue. One-hundred and one patients met the Fukuda criteria. A Chronic Fatigue Questionnaire (CFQ) and Fatigue Impact Scale (FIS) were used to assess the level of mental and physical fatigue. Aortic systolic blood pressure (sBPaortic) and the autonomic nervous system were measured with the arteriograph and Task Force Monitor, respectively. Eighty-two patients suffered prolonged PEM according to the Fukuda criteria, while 19 did not. Patients with PEM had higher FIS scores (p = 0.02), lower central systolic blood pressure (p = 0.02) and higher mental fatigue (p = 0.03). For a one-point increase in the mental fatigue component of the CFQ scale, the risk of PEM increases by 34%. For an sBPaortic increase of 1 mmHg, the risk of PEM decreases by 5%. For a one unit increase in sympathovagal balance, the risk of PEM increases by 330%. Higher mental fatigue and sympathetic activity in rest are related to an increased risk of PEM, while higher central systolic blood pressure is related to a reduced risk of PEM. However, none of the between group differences were significant after FDR correction, and therefore conclusions should be treated with caution and replicated in further studies.

Aims: An abnormal reduction in cerebral blood flow (CBF) during orthostatic stress is common in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), a condition with more prevalent joint hypermobility than in the healthy population. As one of proposed underlying mechanisms of orthostatic intolerance in hypermobile patients is vessel laxity, reducing the normal return of blood to the heart during orthostatic stress, we hypothesized that the CBF reduction during tilt-testing would be larger in ME/CFS patients with joint hypermobility than in patients without hypermobility. Methods: In this case-control study, 100 female ME/CFS cases with joint hypermobility, who had undergone tilt-testing with CBF measurements, were compared to 100 female ME/CFS patients without joint hypermobility, matched by age and disease duration. Results: No differences in baseline characteristics were found between groups. The hypermobile patients had significantly more postural orthostatic tachycardia syndrome (POTS) during tilt testing than the non-hypermobile ones. Compared to supine CBF, the degree of CBF reduction during the tilt was significantly larger in hypermobile cases than in the non-hypermobile controls: -32 (6)% vs -23 (7)% (p<0.0001) The larger CBF reduction in hypermobile patients was not only present in POTS patients: -33 (6)% vs -24 (4)%, but also in patients with a normal heart rate and blood pressure response to tilt testing: -31 (6)% vs -22 (9)%: (both p<0.0001). Conclusions: ME/CFS patients with joint hypermobility syndromes have larger CBF reductions during orthostatic stress testing than patients without hypermobility. This larger CBF reduction is independent of the heart rate and blood pressure results of the orthostatic stress test.
