Impaired left ventricular filling in COPD and emphysema: is it the heart or the lungs?
Pulmonary vein dimensions were reduced in COPD and emphysema. These findings support a mechanism of upstream pulmonary causes of underfilling of the LV in COPD and in patients with emphysema on CT scan.
The results suggest that IL-23-stimulated production of IL-17 by CD4(+) T cells may be responsible for the development of uveitis seen in patients with VKH disease.
