Abstract
Patients with clinical post- coronary artery bypass grafting (CABG) deterioration manifest angiographic disease progression in both the native coronary arteries and aortocoronary conduits. Although clinical results suggest more pronounced impact of failed revascularization in comparison to progression in the native coronary circulation, the latter one is also of clinical importance. Coronary artery disease (CAD) progression in the ungrafted coronaries mimics pathophysiology of atherosclerosis, thus strict control of the commonest risk factors for its development is the therapeutic target. Otherwise, angiographic disease deterioration in the target coronary arteries is a net result of negative remodeling and plaque progression. Analysis of the angiographic post-CABG follow-up indicates that vessel shrinkage (i.e., negative remodeling) dominates. Low endothelial shrear stress resulted from diminished blood flow seems to be the most powerful pathogenetic factor of negative remodeling.
