Abstract

To explore the impact of age and diabetes mellitus (DM) on the ultrastructure of radial artery (RA). From June 2009 to December 2010, 64 patients underwent coronary artery bypass grafting (CABG) with autologous RA: 14 patients aged beyond 65 years without DM [9 male patients and 5 female patients, age (70 ± 4) years] and 18 patients aged beyond 65 years with DM [11 male patients and 7 female patients, age (68 ± 5) years], 20 patients aged under 60 years without DM [13 male patients and 7 female patients, age (53 ± 5) years] and 12 patients aged under 60 years with DM [7 male patients and 5 female patients, age (51 ± 6) years]. Four groups were subjected to routine electron microscopic examination and transmission electron microscopic examination. There were significant differences in percentage of endothelial denudation among four groups according to scanning electron microscopic evaluation (χ² = 18.082, P = 0.000). To compare with each other, there were significant differences between DM elderly patients and non-DM elderly patients, also between DM young patients and non-DM young patients according to scanning electron microscopic evaluation. There were no significant differences between DM elderly patients and DM young patien...Continue Reading
