BACKGROUND
The aim of the present study was to explore the value of coronary artery calcium score (CACS) using non-gated, non-contrast chest computed tomography (NCCT) to predict coronary artery disease (CAD) in airline pilots.
METHODS
Pilots with coronary calcification found on NCCT were consecutively enrolled into this study. All received a coronary computed tomography angiography (CCTA) examination. The coronary artery calcium score (CACS) was evaluated on NCCT using the Agatston method. CCTA images were analyzed using a semi-automated software. Coronary Artery Disease Reporting and Data System (CAD-RADS) scoring categorized coronary stenosis.
RESULTS
A total of 217 male pilots were included, of which 49 were diagnosed with significant CAD (CAD-RADS category 3 or higher). Pilots with significant CAD had much higher CACS (324.28 ± 389.02 vs. 39.16 ± 68.88; < 0.001). Plaque volumetric measurements showed that total plaque volume (1,103.50 ± 285.51 mm vs. 913.18 ± 277.45 mm; < 0.001) and calcified plaque volume (149.77 ± 160.71 mm vs. 36.42 ± 26.86 mm; < 0.001) were more pronounced in individuals in the significant CAD group than those in the non-significant CAD group. A multivariate analysis demonstrated that CACS (odds ratio 1.01; 95% confidence interval 1.005-1.014; < 0.001) was the only independent risk factor of significant CAD but traditional cardiovascular risk factors, pre-existing medication regimens, or prolonged flight duration were not. CACS positively correlated with total plaque volume ( = 0.156; = 0.027) and calcified plaque volume ( = 0.434; < 0.001). Receiver operating characteristic curve analysis showed the area under the curve for the CACS in diagnosing significant CAD was 0.891 ( < 0.001).
CONCLUSIONS
CACS assessed using NCCT was significantly associated with CAD-RADS category 3 or higher, as confirmed by CCTA, which indicates that it may serve as a robust predictor for diagnosing significant CAD among airline pilots.
背景
本研究的目的是探讨使用非门控、非增强胸部计算机断层扫描（NCCT）获得的冠状动脉钙化积分（CACS）预测航空公司飞行员冠状动脉疾病（CAD）的价值。
方法
连续纳入在NCCT上发现冠状动脉钙化的飞行员进行本研究。所有受试者均接受了冠状动脉计算机断层扫描血管造影（CCTA）检查。使用阿加特斯顿方法在NCCT上评估冠状动脉钙化积分（CACS）。使用半自动软件分析CCTA图像。冠状动脉疾病报告和数据系统（CAD-RADS）评分对冠状动脉狭窄进行分类。
结果
共纳入217名男性飞行员，其中49名被诊断为重度CAD（CAD-RADS分类为3级或更高）。重度CAD的飞行员CACS显著更高（324.28±389.02 vs. 39.16±68.88；P<0.001）。斑块体积测量显示，重度CAD组个体的总斑块体积（1103.50±285.51 mm vs. 913.18±277.45 mm；P<0.001）和钙化斑块体积（149.77±160.71 mm vs. 36.42±26.86 mm；P<0.001）比非重度CAD组更明显。多变量分析表明，CACS（比值比1.01；95%置信区间1.005-1.014；P<0.001）是重度CAD的唯一独立危险因素，而传统心血管危险因素、既往用药方案或飞行时间延长则不是。CACS与总斑块体积（r=0.156；P=0.027）和钙化斑块体积（r=0.434；P<0.001）呈正相关。受试者工作特征曲线分析显示，CACS诊断重度CAD的曲线下面积为0.891（P<0.001）。
结论
经CCTA证实，使用NCCT评估的CACS与CAD-RADS分类为3级或更高显著相关，这表明它可能是诊断航空公司飞行员重度CAD的有力预测指标。
