Circulation:低复杂性先天性心脏病个体的心血管疾病发病率

2019-04-22 qinqiyun MedSci原创

虽然大部分成人先天性心脏病(ACHD)心脏畸形的复杂性较低,但目前对这一人群心血管不良事件的长期风险以及与传统风险因素的关系知之甚少。现研究人员对与低复杂性ACHD相关的不良心血管事件的风险进行量化。采用多层分类算法从英国50多万成年人中筛选低复杂性ACHD个体和无ACHD个体。ACHD分为孤立主动脉瓣和非复杂性缺陷两种。主要评估结点:致死性或非致死性急性冠状动脉综合征、缺血性卒中、心力衰竭和房颤

虽然大部分成人先天性心脏病(ACHD)心脏畸形的复杂性较低,但目前对这一人群血管不良事件的长期风险以及与传统风险因素的关系知之甚少。现研究人员对与低复杂性ACHD相关的不良血管事件的风险进行量化。

采用多层分类算法从英国50多万成年人中筛选低复杂性ACHD个体和无ACHD个体。ACHD分为孤立主动脉瓣和非复杂性缺陷两种。主要评估结点:致死性或非致死性急性冠状动脉综合征、缺血性卒中、心力衰竭和房颤,次要评估结点:主要不良心血管事件。最长随访时间为22年。

共筛选出2006位低复杂性ACHD个体和497983位对照(中位年龄58岁[51-63])。ACHD队列,59%为男性,51%目前或既往吸烟,30%的个体肥胖,而且分别69%、41%和7%的个体患有高血压、高血脂和糖尿病。根据12项评估的心血管风险因素校正后,ACHD仍与主要评估结点密切相关,急性冠脉综合征的危险比(HR)为2.0(95% CI 1.5-2.8),心衰的HR高达13.0(95% CI 9.4–18.1; P<0.001)。经年龄校正后,心血管风险因素≤2个的ACHD个体重大心血管不良事件的发生率为29%,而风险因素≥5个的非ACHD个体的发生率仅13%。

与普通人群相比,低复杂性ACHD个体发生心血管不良事件的风险较高,提示有必要对轻至中度ACHD患者进行更密切的监测,并进一步研究该不断增加的高危成人人群特异性的心血管风险管理和发生机制。
