Aim To observe the characteristics of coronary artery calcium （CAC） and coronary artery calcium score（CACS） in the village population in Yunnan province. Methods Coronary calcium scan with 16-MDCT was performed in 174 cases sampled randomly from the village population in Yunnan province. Coronary artery calcium score was calculated. The characteristics and difference of CAC and CACS were compared between groups of gender, age and race. Results The positive rate of CAC in 174 samples was 22.4% and 39 samples with CACS≥1, the positive rate of CAC in 51～60 years group and 61～71 years group was 15.5% and 34.4% respectively and the CACS was 11.2±52.4 and 38.0±82.0. The difference of CAC and CACS in these groups had remarkable statistical significance （P<0.05）, however, these index between the gender and race had no statistical significance, the positive rate of CAC in coronary artery was LAD＞LCX＝RCA＞LM. Conclusions CAC and CACS had age differences in age group of 51～71 years of the village population in Yunnan. The highest incidence of CAC was in the 1eft anterior descending artery, followed by 1eft circumflex artery and right coronary artery.
