Is there functional collateral flow during vascular occlusion in angiographically normal coronary arteries?
In humans with angiographically normal coronary arteries, there are functional collateral vessels to the extent that one fifth to one quarter of them do not show signs of myocardial ischemia during brief vascular occlusions.
Our study illustrates chronically activated B cells alongside autoantigens and B-cell survival factors in the mucosa in GPA.
