To evaluate the relationship between aortic arch calcification and clinical and radiographical parameters on chest radiography.
We retrospectively evaluated 242 consecutive patients that were admitted to our intensive care unit for dyspnea. Chest radiography was performed for all patients with the posteroanterior view. Cardiothoracic ratio (CTR), mediastinal ratio (MR), aortic width (AW) parameters and the grade of aortic calcification were recorded. Patients with grade 1, 2 or 3 were defined as the calcification-positive (+) group and patients having no calcification (grade 0) were defined as the calcification-negative (-) group. Statistical analyses were performed on both groups.
The study population consisted of 124 (51.2%) female and 118 (48.8%) male patients. The mean age was 67 ± 12 (range: 25-101) years. There was no significant relationship between aortic arch calcification and gender, presence of hypertension, diabetes mellitus, lipid levels, AW and MR, but age was correlated positively with aortic arch calcification with high statistical significance (p<0.0001). In patients with coronary artery disease (CAD), the prevalence of aortic arch calcification tended to be higher but was not statistically significant (p=0.07). The grade of calcification was not found to be correlated with gender, comorbidity, lipid levels, MR or CTR. However, as the grade of calcification increased, the mean age of patients in consecutive calcification grade groups tended to increase significantly. CTR, MR and AW increased with age. However, on regression analysis, only age was found to be an independent factor for aortic knob calcification (β=0.397, t=6.375, p<0.0001).
Simple, useful radiographical parameters such as AW, CTR, MR and calcification grade can help to predict the etiology of dyspnea and cardiovascular disease.
评估胸部X线片上主动脉弓钙化与临床及影像学参数之间的关系。
我们回顾性评估了242例因呼吸困难入住重症监护病房的连续患者。所有患者均拍摄了后前位胸部X线片。记录心胸比率（CTR）、纵隔比率（MR）、主动脉宽度（AW）参数以及主动脉钙化分级。将钙化分级为1级、2级或3级的患者定义为钙化阳性（+）组，无钙化（0级）的患者定义为钙化阴性（-）组。对两组进行统计学分析。
研究人群包括124例（51.2%）女性和118例（48.8%）男性患者。平均年龄为67±12岁（范围：25 - 101岁）。主动脉弓钙化与性别、高血压、糖尿病、血脂水平、AW和MR之间无显著关系，但年龄与主动脉弓钙化呈高度正相关，具有统计学意义（p<0.0001）。在冠心病（CAD）患者中，主动脉弓钙化的患病率倾向于更高，但无统计学意义（p = 0.07）。未发现钙化分级与性别、合并症、血脂水平、MR或CTR相关。然而，随着钙化分级增加，连续钙化分级组患者的平均年龄倾向于显著增加。CTR、MR和AW随年龄增加。然而，回归分析显示，只有年龄是主动脉结钙化的独立因素（β = 0.397，t = 6.375，p<0.0001）。
诸如AW、CTR、MR和钙化分级等简单、有用的影像学参数有助于预测呼吸困难和心血管疾病的病因。
