Aortic dissection is a lethal medical diagnosis associated with high morbidity and mortality. Currently published studies have noted a rising incidence of aortic dissection globally as well as a downward trend in mortality secondary to aortic dissection. There remains no nationally available study here in Aotearoa New Zealand looking into the incidence and mortality of aortic dissection.
A retrospective observational study was performed using data extracted from the Manatū Hauora - Ministry of Health National Minimum Dataset (NMDS) from 1 July 2001 to 30 June 2021. Diagnosis of aortic dissection was based on the ICD-10 version 2 code for aortic dissection (I7100). Population-based statistics were obtained from Statistics New Zealand.
A total of 4,737 patients were included in the study over the 20-year period. The incidence rate of aortic dissection in Aotearoa New Zealand is rising and the current median incidence rate is 4.99 per 100,000 per annum. The mortality rate from aortic dissection is slowly decreasing in Aotearoa New Zealand and the current median mortality rate is 2.19 per 100,000 per annum.
There appears to be a rise in the incidence of aortic dissection in Aotearoa New Zealand and a decrease in the mortality rate.
主动脉夹层是一种致死性的医学诊断，与高发病率和死亡率相关。目前已发表的研究指出，全球范围内主动脉夹层的发病率呈上升趋势，且继发于主动脉夹层的死亡率呈下降趋势。在新西兰，尚无全国性的研究探讨主动脉夹层的发病率和死亡率。
采用回顾性观察研究，使用从2001年7月1日至2021年6月30日期间从新西兰卫生部国家最低数据集（NMDS）中提取的数据。主动脉夹层的诊断基于国际疾病分类第10版第2版中主动脉夹层的编码（I7100）。基于人群的统计数据来自新西兰统计局。
在20年的研究期间，共有4737名患者被纳入研究。新西兰主动脉夹层的发病率呈上升趋势，目前的年发病率中位数为每10万人4.99例。新西兰主动脉夹层的死亡率正在缓慢下降，目前的年死亡率中位数为每10万人2.19例。
新西兰主动脉夹层的发病率似乎在上升，而死亡率在下降。
