JACC:黑种人的心源性猝死风险明显高于白种人

2018-11-13 MedSci MedSci原创

既往有研究报道黑种人的心源性猝死(SCD)风险比白种人高近两倍,然而这些分析缺乏个体水平的社会人口学、医疗并发症和行为健康数据等。本研究的目的旨在评估种族差异造成的SCD差异是否对危险因素患病率的差异或者致命性心律失常的潜在易感性有影响。本研究纳入分析了22507名(9416名黑种人和13091名白种人)无心血管疾病史的个体,经过平均6.1年时间的随访,共有174例SCD事件发生(67例白种人和1

既往有研究报道黑种人的心源性猝死(SCD)风险比白种人高近两倍,然而这些分析缺乏个体水平的社会人口学、医疗并发症和行为健康数据等。本研究的目的旨在评估种族差异造成的SCD差异是否对危险因素患病率的差异或者致命性心律失常的潜在易感性有影响。

本研究纳入分析了22507名(9416名黑种人和13091名白种人)无血管疾病史的个体,经过平均6.1年时间的随访,共有174例SCD事件发生(67例白种人和107例黑种人)。年龄调整后的SCD发生率在黑种人中要更高(HR:2.35; 95% CI: 1.74 - 3.20),在经过社会人口统计学、合并症、行为健康措施、血管事件干预和非SCD死亡率的竞争风险调整后,黑种人的SCD发生率依旧更高(HR:1.97; 95% CI: 1.39 - 2.77)。

本研究结果显示,黑种人的心源性猝死风险比白种人更高,且这种相关性不受人口统计学、不良社会经济措施、心血管危险因素和行为健康措施影响。
