目的 :冠状动脉钙化是冠状动脉粥样硬化的标志 ,电子束 CT是非创伤检测冠状动脉钙化的首选方法。本研究旨在研究中国人冠状动脉钙化的检出率。 方法 :用 EBCT检测 95 9例患者 ,按年龄分为 6组 :1<2 9岁 ;2 30～39岁 ;34 0～ 49岁 ;45 0～ 5 9岁 ;5 6 0～ 6 9岁 ;6 >70岁 ;根据有无症状分为三个亚组 :1症状组 :有典型冠心病症状 ;2可疑症状组 :患者有非典型胸痛 ,但无足够证据证明其为心绞痛 ;3无症状组 :患者无冠心病症状。 结果 :1无症状男女性随年龄增加 ,其冠状动脉钙化检出率及总积分增加 ;2无症状女性 40～ 49岁组和 5 0～ 5 9岁组冠状动脉钙化检出率增加 ;3无症状男性随着年龄的增加 ,其冠状动脉钙化积分增加。 结论 :1中国人男女性别随着年龄增加其冠状动脉钙化检出率增加 ;2男女性别间钙化检出率明显不同 ;3EBCT可无创性检测冠状动脉钙化 ,对冠状动脉疾病有预测价值。
Purpose: Coronary artery calcification is a marker of coronary atherosclerosis. Electron beam CT is the preferred method for non-invasive detection of coronary artery calcification. This study aims to study the detection rate of coronary artery calcification in Chinese. METHODS: A total of 95 9 patients were examined by EBCT and divided into 6 groups according to age: 1<2 9 years; 2 30 to 39 years; 34 0 to 49 years; 45 0 to 5 9 years; 6 >70 years old; divided into three subgroups according to whether or not there are symptoms: 1 Symptom group: typical symptoms of coronary heart disease; 2 Suspicious symptoms group: The patient has atypical chest pain, but there is insufficient evidence to prove that it is angina; 3 Asymptomatic group : The patient had no symptoms of coronary heart disease. RESULTS: 1 Asymptomatic male and female sexes increased with age, and the detection rate and total score of coronary artery calcification increased. 2 The detection rate of coronary artery calcification increased in asymptomatic women aged 40-49 years and 50-59 years old. Symptoms Males have increased coronary calcium scores as they age. Conclusion :1 The detection rate of coronary artery calcification in Chinese male and female genders increases with age;2 The detection rate of calcification between male and female genders is significantly different;3EBCT can non-invasively detect coronary artery calcification and has predictive value for coronary artery disease.
