WebStructure et fonctions des hémoglobines. L’hémoglobine est un hétérotétramère composé de quatre chaines polypeptidiques, les chaines de globine, dont il existe plusieurs entités (leur structure primaire). Normalement, une molécule d’hémoglobine est formée de deux types de chaines, identiques deux à deux. WebBackground: Many studies have shown that glycated hemoglobin (HbA1c) is associated with coronary artery disease (CAD). HbA1c was independently related to angiographic severity in Chinese patients with CAD after adjusting for other covariates. Some traditional cardiovascular drugs may have an impact on this relationship.
