Fibrocellular tissue response after percutaneous transluminal coronary angioplasty. An immunocytochemical analysis of the cellular composition.

abstract：:Background-Homozygosity for a relatively common Cys282Tyr mutation of the human hemochromatosis-associated (HFE) gene was recently found to account for most cases of hereditary hemochromatosis. Because excess iron has been postulated to enhance risk of vascular disease, we studied whether occurrence of this mutation w...
