Small heart with low cardiac output for orthostatic intolerance

From Miwa and Fujita at the Miwa Naika Clinic (Japan), a report that CFS patients with orthostatic intolerance (OI) (n=26) and patients with OI (alone) (n=11) may have smaller hearts and reduced cardiac performance. A small heart appears to be related to the genesis of OI and CFS via both cerebral and systemic hypoperfusion. Agreeing with other reports, CFS with OI seems to constitute a well-defined and predominant subgroup of CFS. (Journal of Clinical Cardiology, Nov. 28, 2011; full text available)
