Abstract

Purpose: According to recent studies, multidetector-row CT (MDCT) with a retrospective ECG-gating reconstruction algorithm shows a high correlation with coronary artery calcium score determined using electron-beam CT. Diabetes leads to many macrovascular complications, including coronary artery disease. The aim of this study was to evaluate risk factors for cardiac macroangiopathy in type 2 diabetes using MDCT.

Materials and methods: An observational cross-sectional study was performed in 90 patients with diabetes mellitus. Coronary calcium data was acquired by MDCT (SOMATOM Volume Zoom, Siemens AG, Medical Solutions, Germany). Physical examinations, laboratory data, glycemic control, and control of other risk factors were analyzed.

Results: The coronary artery calcium score increased with age. Multivariant analysis revealed that the coronary calcium score was closely correlated with electrocardiogram evaluation and control of hypertension.

Conclusions: Coronary artery calcium score as determined by MDCT can be used as a screening radiological examination for cardiac macroangiopathy in diabetes patients with electrocardiogram abnormality and hypertension.

[多排CT评价2型糖尿病患者冠状动脉钙评分的临床价值]。

目的:根据最近的研究，采用回顾性心电图门控重建算法的多排CT (multidetector-row CT, MDCT)与电子束CT测定的冠状动脉钙评分有很高的相关性。糖尿病导致许多大血管并发症，包括冠状动脉疾病。本研究的目的是利用MDCT评估2型糖尿病患者心脏大血管病变的危险因素。材料与方法:对90例糖尿病患者进行观察性横断面研究。冠状动脉钙数据由MDCT (SOMATOM Volume Zoom, Siemens AG, Medical Solutions, Germany)获取。分析体格检查、实验室数据、血糖控制和其他危险因素的控制情况。结果:冠状动脉钙化评分随年龄增长而升高。多变量分析表明，冠状动脉钙评分与心电图评价及高血压控制密切相关。结论:MDCT冠状动脉钙化评分可作为糖尿病合并心电图异常和高血压患者心脏大血管病变的影像学筛查。
