摘要

目的:目前缺乏对升主动脉直径的大规模调查,尤其是在亚洲人群中。此外,有关高血压(HP)、主动脉瓣双瓣(BAV)和马凡综合征(MFS)分布的相关证据也很少。我们旨在研究升主动脉直径在中国这些人群中的分布情况:我们对接受心脏超声检查的 698 795 人的数据进行了回顾性分析。经过筛选,647 087 人被纳入最终分析。正常人群的升主动脉平均直径为 28.1 ± 3.2 毫米(女性为 27.2 ± 3.1 毫米,男性为 29.0 ± 3.1 毫米)(P < 0.001)。主动脉直径随着年龄的增长而逐渐增大(P < 0.001)。在 HP 患者中,主动脉扩张、动脉瘤和夹层的发病率分别为 12.83%、2.70% 和 4.77%。在 MFS 患者中,相应的发病率分别为 43.92%、35.31% 和 26.11%。值得注意的是,虽然 BAV 患者主动脉扩张(37.00%)和主动脉瘤(16.46%)的发病率较高,但主动脉夹层的发病率相对较低(0.74%)。大多数主动脉夹层病例的主动脉直径小于 55 毫米。结论:(i) 升主动脉直径随年龄增长而增大,男性大于女性;(ii) "主动脉悖论 "得到解释;(iii) BAV 的主动脉扩张率高,但主动脉夹层发生率低。

Aortic size distribution among normal, hypertension, bicuspid, and Marfan populations.

Aims: Large-scale investigations on ascending aortic diameter, especially in the Asian population, are lacking. Furthermore, relevant evidence regarding the distribution of hypertension (HP), bicuspid aortic valve (BAV), and Marfan syndrome (MFS) is scarce. We aimed to examine the distribution of ascending aortic diameter in these populations in China.

Methods and results: The data of a total number of 698 795 individuals who underwent cardiac ultrasound were subjected to retrospective analysis. After screening, 647 087 individuals were included in the final analysis. In the normal population, the mean ascending aortic diameter was 28.1 ± 3.2 mm (27.2 ± 3.1 mm in women vs. 29.0 ± 3.1 mm in men) (P < 0.001). Aortic diameter increased gradually with age (P < 0.001). The prevalence of aortic dilation, aneurysm, and dissection in individuals with HP was 12.83%, 2.70%, and 4.77%, respectively. In individuals with MFS, the corresponding rates were 43.92%, 35.31%, and 26.11%. Notably, although BAV patients had high incidences of aortic dilation (37.00%) and aortic aneurysm (16.46%), the incidence of aortic dissection was relatively low (0.74%). Most cases of aortic dissection occurred at an aortic diameter of less than 55 mm. However, in the overall population, the incidence of aortic dissection significantly increased with the increase in the aortic diameter, revealing the existence of an 'aortic paradox'.

Conclusions: (i) The ascending diameter increases with age and is larger in men than in women; (ii) 'Aortic paradox' is explained; (iii) BAV bears a high rate of aortic dilation, but a low incidence of aortic dissection.
