Background The coronary artery calcium (CAC) and aortic arch calcification (AoAC) are individually associated with cardiovascular disease and outcome. This study investigated the predictive value of AoAC combined with CAC for cardiovascular diagnosis and outcome in patients with angina. Methods A total of 2018 stable angina patients who underwent chest X-ray and cardiac multi-detector computed tomography were followed up for four years to assess adverse events, which were categorized as cardiac death, stroke, myocardial infarction, or repeated revascularization. The extent of AoAC on chest X-ray was graded on a scale from 0 to 3. Results During the four years of fol- low-up, 620 patients were treated by coronary stenting and 153 (7%) adverse events occurred. A higher grade of AoAC was associated with a higher CAC score. Cox regression showed that the CAC score, but not AoAC, were associated with adverse events. In patients with CAC score 〈 400, AoAC showed an additive predictive value in detecting significant coronary artery disease (CAD). A gradual increases in the risk of adverse events were noted if AoAC was present in patients with similar CAC score. Conclusions As AoAC is strongly correlated with the CAC score regardless of age or gender, careful evaluation of CAD would be required in patients with AoAC on conventional chest X-rays. 展开更多
