Coronary artery calcium measured by CT predicts future coronary events. Similarly, carotid artery calcium on dental panoramic radiographs has been associated with increased cardiovascular events. Pre-procedural assessment of candidates for valve replacement in our institution includes panoramic radiographs and chest tomography. We aimed to assess the association of carotid calcium on panoramic radiographs with coronary artery calcium on chest tomography.
Paired pre-procedural panoramic radiographs and chest tomography scans were done in 177 consecutive patients between October 2016 and October 2017. Carotid calcium was quantified using NIH's ImageJ. Coronary artery calcium was quantified by the Agatston score using Philips Intellispace portal, v. 8.0.1.20640.
Carotid calcium maximal intensity, area and perimeter were higher among patients with high coronary artery calcium. Non-zero carotid calcium was found in half of patients with high coronary artery calcium, doubling prevalence of low coronary artery calcium.
Carotid calcium identified in panoramic radiographs was associated with high coronary artery calcium. Awareness of carotid calcium recognized by dental practitioners in low-cost, low radiation and commonly done panoramic radiographs may be useful to identify patients at risk of coronary disease with potential future cardiovascular events.
CT 检测到的冠状动脉钙可预测未来的冠状动脉事件。同样，牙全景片上的颈动脉钙与心血管事件的增加有关。在我们机构中，瓣膜置换候选者的术前评估包括全景片和胸部 CT 扫描。我们旨在评估牙全景片上的颈动脉钙与胸部 CT 上的冠状动脉钙之间的关联。
2016 年 10 月至 2017 年 10 月期间，对 177 例连续患者进行了术前配对的全景片和胸部 CT 扫描。使用 NIH 的 ImageJ 定量颈动脉钙。使用飞利浦 Intellispace 门户（v. 8.0.1.20640）通过 Agatston 评分定量冠状动脉钙。
冠状动脉钙高的患者颈动脉钙最大强度、面积和周长较高。在冠状动脉钙高的患者中，有一半存在非零颈动脉钙，使冠状动脉钙低的患病率增加了一倍。
在全景片中识别出的颈动脉钙与冠状动脉钙高有关。牙医师在低成本、低辐射且通常进行的全景片中识别出的颈动脉钙可能有助于识别患有潜在未来心血管事件的冠心病高危患者。
