Autonomic dysfunction, cardio-pulmonary exercise testing and masked heart failure with preserved ejection fraction in non-severe chronic obstructive pulmonary disease.

abstract：:Studies using arterial spin labelling (ASL) have shown that individuals with chronic fatigue syndrome (CFS) have decreased regional cerebral blood flow, which may be associated with changes in functional neural networks. Indeed, recent studies indicate disruptions in functional connectivity (FC) at rest in chronically...
