JACC:自发性冠脉夹层的遗传易感因素研究

2019-01-11 MedSci MedSci原创

自发性冠状动脉夹层(SCAD)被认为是导致年轻-中年女性急性冠脉综合征(ACS)的主要原因之一,有研究报道了该类疾病冠脉以外的血管畸形,尤其是纤维肌肉发育不良(FMD),并少量病例伴有动脉粥样硬化。PHACTR1/EDN1基因是许多血管畸形的遗传易感位点,包括FMD和冠脉疾病,并且推测位于EDN1基因增强子上的一个非编码突变(rs9349379)为主要原因。本研究的目的旨在探究rs9349379与

自发性冠状动脉夹层(SCAD)被认为是导致年轻-中年女性急性冠脉综合征(ACS)的主要原因之一,有研究报道了该类疾病冠脉以外的血管畸形,尤其是纤维肌肉发育不良(FMD),并少量病例伴有动脉粥样硬化。PHACTR1/EDN1基因是许多血管畸形的遗传易感位点,包括FMD和冠脉疾病,并且推测位于EDN1基因增强子上的一个非编码突变(rs9349379)为主要原因。本研究的目的旨在探究rs9349379与SCAD的相关性。

本研究纳入分析了来自法国、英国、美国和澳大利亚几个国家的病例对照研究,发现rs9349379-A在所有研究中均与SCAD呈相关性。在一个包含1055名SCAD患者和7190名对照的荟萃分析研究中,rs9349379-A对SCAD的OR值为1.67(95% [CI]: 1.50-1.86),在亚组分析中发现,rs9349379-A与SCAD的相关性在无FMD患者中更高(OR: 1.89; 95% CI: 1.53-2.33)。

本研究在一个目前最大的SCAD队列中揭示了一个遗传易感因素(rs9349379-A)。
