摘要 目的:探讨不同阿司匹林抵抗类型急性脑梗死患者服用阿司匹林后血小板聚集率(PAG)及血栓素B2(TXB2)与6-酮-前列腺素(6-k-PGF1a)的变化及临床意义。方法:将80例急性脑梗死患者根据阿司匹林抵抗的不同分为阿司匹林抵抗(AR)组6例,阿司匹林部分抵抗(ASR)组18例,阿司匹林敏感(AS)组56例。分别测定各组患者服用阿司匹林前及服用阿司匹林(服用剂量为100mg/d)1周后血栓素B2(TXB2)及6-酮-前列腺素(6-k-PGF1a)的浓度,并进行对比分析。结果:用药前3组间各检测指标的差异均无统计学意义(均P>0.05),服用阿司匹林1周后,3组患者PAG及TXB2检测指标显著低于用药前(均P<0.01);而6-k-PGF1a检测指标显著高于用药前(均P<0.01)。用药1周后,TXB2浓度与AS组用药后比较,ASR组各指标并无明显变化(均P>0.05)。而AR组各检测指标均显著高于AS组(均P<0.01);与ASR组用药后比较,AS组各指标并无明显变化(均P>0.05),AR组血TXB2浓度均显著高于ASR组(均P<0.01)。6-k-PGF1a浓度与AS组用药后比较,ASR组各指标并无明显变化(P>0.05)。而AR组各检测指标均显著低于AS组(均P<0.01);与ASR组用药后比较,AS组各指标并无明显变化(均P>0.05)。结论:阿司匹林可降低急性脑梗死患者的PAG和TXB2,并提高6-k-PGF1a。有可能在一定程度上降低急性脑梗死患者再发的危险。
