ABO血型与急性心肌梗死患者梗死相关动脉自发再通的相关性研究

摘要

目的:探讨ABO血型与急性心肌梗死(AMI)患者梗死相关动脉自发再通的相关性.方法:连续入选1209例AMI患者,根据心肌梗死溶栓治疗临床试验(TIMI)血流程度将患者分为非自发再通组(TIMI 0~1级,n=442)和自发再通组(TIMI 2~3级,n=767),分析研究ABO血型与自发再通发生的关系.结果:本研究显示,与非自发再通组相比,自发再通组中O型血较常见(32.3%vs 24.7%),A型血者较为少见(31.7%vs 24.9%).同时,我们发现O型血患者的致动脉粥样硬化性胆固醇包括总胆固醇和低密度脂蛋白胆固醇明显低于非O型血患者(P<0.05).多因素回归分析表明,校正年龄、性别、体重指数、高血压、糖尿病、吸烟、低密度脂蛋白胆固醇及C反应蛋白、血沉、纤维蛋白原、D-二聚体、内皮心肌功能等因素后,O型血可独立预测AMI患者自发再通的发生[比值比(OR)=1.49,95%可信区间(CI):1.10~2.05)],A型血则不利于自发再通的发生(OR=0.65,95%CI:0.48~0.80).结论:ABO血型与AMI患者自发再通的发生有关.其中,O型血有利于患者自发再通的发生,而A型血不利于自发再通的发生.%Objective: To study the relationship between ABO blood type and spontaneous re-canalization (SR) in patients with acute myocardial infarction (AMI). Methods: A total of 1209 consecutive AMI patients were enrolled. Based on TIMI grade, the patients were divided into 2 groups: Non-SR group, the patients with TIMI grade 0-1,n=442 and SR group, the patients with TIMI grade 2-3,n=767. The relationship between ABO blood type and SR was investigated. Results: Compared with Non-SR group, SR group had more patients with blood type O (32.3% vs 24.7%) and less blood type A (31.7% vs 24.9%). Meanwhile, we found that a lower cholesterol level was related to patients with O blood type and SR occurrence, bothP<0.05. Multi regression analysis indicated that with adjusted age, gender, BMI, hypertension, diabetes, smoking, LDL-C and C-reactive protein, ESR, fibrinogen, D-dimmer, endothelial cardiac function, blood type O may independently predict SR occurrence in AMI patients (OR=1.49, 95% CI 1.10-2.05), while blood type A may have disadvantage for SR (OR=0.65, 95% CI 0.48-0.80). Conclusion: ABO blood type has been related to SR in AMI patients, blood type O is in favor of SR, while blood type A has disadvantage for SR occurrence.
