目的探讨颈动脉内膜中层厚度(IMT)与心血管病危险因素聚集性的关系。方法对78例心血管疾病患者行颈动脉超声检查,测定颈动脉IMT,同时测定血压、血糖、血脂、身高、体重、腰围等,按颈动脉IMT是否小于0.85mm分成IMT正常组和IMT增厚组。并对两组的收缩压、舒张压、血糖、血脂、体重指数、腰围等进行比较。结果IMT增厚组患者与IMT正常组比较,收缩压、舒张压明显增高,组间比较差异有统计学意义(P<0.05)。直线相关分析显示,颈总动脉IMT与收缩压及舒张压均呈正相关(r分别为0.257、0.235,P<0.05)。颈内动脉IMT与收缩压及舒张压也均呈正相关(r分别为0.421、0.350,P<0.05)。结论颈动脉IMT与心血管病危险因素相关。
Objective To investigate the relationship between carotid intima-media thickness (IMT) and the risk of cardiovascular disease. Methods 78 patients with cardiovascular disease underwent carotid ultrasonography to measure the carotid IMT, and to determine the blood pressure, blood glucose, blood lipid, height, weight, waist circumference and so on. According to whether the carotid IMT was less than 0.85mm, group. The systolic blood pressure, diastolic blood pressure, blood glucose, blood lipids, body mass index, waist circumference and so on were compared. Results Compared with IMT normal group, systolic pressure and diastolic pressure were significantly increased in patients with IMT thickening group, the difference was statistically significant (P <0.05). Linear correlation analysis showed that carotid artery IMT and systolic and diastolic blood pressure were positively correlated (r = 0.257,0.235, P <0.05). Internal carotid artery IMT and systolic and diastolic blood pressure also showed a positive correlation (r = 0.421,0.350, P <0.05). Conclusion Carotid artery IMT is associated with cardiovascular risk factors.
