title: [Relationship of coronary artery calcification identified by electron beam tomography with age and gender].
abstract: OBJECTIVE
  To investigate the relationship of coronary artery calcification identified by electron beam tomography with age and gender.
  
  
  METHODS
  Electron beam tomography was performed in 654 patients to detect coronary artery calcification. Examinations were done with electron beam tomography (Imatron C-150 XP), using prospective electrocardiography triggering to prevent cardiac motion artifacts. Total calcification scores were calculated based on the number, area and computed tomographic number of the calcifications. The influence of age and gender on the presence and amount of coronary artery calcification were evaluated.
  
  
  RESULTS
  There were significant differences (p < 0.001) in mean total calcification scores between men and women. Men always had more coronary artery calcification than women at all age groups. The youngest patient with coronary artery calcification was below 40 years of age in men and above 40 years of age in women. The difference in the prevalence of coronary artery calcification between men and women was great at younger ages, and decreased after age 60. The difference in prevalence of coronary artery calcification for men and women was starting to be decreased after age 60.
  
  
  CONCLUSIONS
  We observed that coronary artery calcification, a marker of arteriosclerosis, is strongly associated with age and gender.
