摘要: 目的 探讨冠状动脉粥样硬化性心脏病(冠心病)患者阿司匹林抵抗(AR)的发生率及临床特点.方法 102例入选者均为确诊冠心病患者,入院前或入院后均服用阿司匹林100 mg/d,服用时间≥2周.检测分别由二磷酸腺苷(ADP)和花生四烯酸(AA)诱导的血小板聚集率(PAG)、血、尿血栓素B2(TXB2)、血脂、高敏C反应蛋白(hs-CRP)等指标.根据PAG将患者分为阿司匹林抵抗组(AR)和阿司匹林敏感组(AS);根据尿TXB2质量浓度分为质量浓度高和低2组.分别对每2组进行比较.结果 102例冠心病患者中有13例的PAG(由ADP和AA诱导)均高于判定标准,AR发生率为12.7%;AR组的PAG和尿TXB2质量浓度均高于AS组,差异均有统计学意义(P<0.05),血TXB2 2组相比差异无统计学意义;尿TXB2高组的hs-CRP高于尿TXB2低组,差异有统计学意义(P<0.05).结论在服用阿司匹林的冠心病患者中12.7%出现AR.在长期服用阿司匹林的冠心病患者中,部分人的血小板聚集和TXA2的合成未被有效抑制,存在阿司匹林抵抗现象.

Abstract: Objective To investigate aspirin resistance (AR) in the aspirin-treated patients with coronary artery disease, and further to evaluate the clinical characteristics of them.Methods We prospectively enrolled 102 patients with coronary artery disease on aspirin ( 100 mg/d for ≥2 weeks ) with no other anti-platelet agents. We tested for AR by optical platelet aggregation (PAG) using ADP and AA plasma and urine thromboxane B2 (TXB2) concentration were measured by TXB2 kits. AR was defined as a most PAG of ≥50% with ADP and ≥30% with AA.Results Of the patients studied, 13 (12.7%) were AR. The PAG of AR group was higher than AS group (P<0.01). Urine TXB2 of AR group was higher than AS group. Plasma TXB2 was no statistical diversity between groups. The hs-CRP of group with high TXB2 is higher than the hs-CRP of group with low TXB2.Conclusion This study detect 12.7% AR in 102 cases aspirin-treated patients with coronary artery disease.
