在接受双抗血小板治疗的稳定冠状动脉疾病患者中,素 (COLC) 并没有显著改变血小板活性. 这项研究没有发现阿司匹林或克洛皮多格雷尔反应的显著变化,这表明COLC可能不会影响抗血小板功效.
科学领域:
- 药理动力学是什么 药理动力学
- 心血管医学 心血管医学
- 临床药理学 临床药理学
背景情况:
- 稳定的冠状动脉疾病 (CAD) 患者通常需要用阿司匹林和克洛皮多格雷尔进行双重抗血小板治疗 (DAPT).
- 评估额外药物对DAPT疗效的影响对于患者管理至关重要.
- 胆固醇 (COLC) 用于各种炎症状况.
研究的目的:
- 为了评估口服胆固醇 (COLC) 0.5毫克每天一次14天对血小板反应性的药理动力学影响.
- 为了评估阿司匹林反应单位 (ARU) 和P2Y12反应单位 (PRU) 在DAPT.患者的变化.
主要方法:
- 一项前性单臂研究,涉及22名在DAPT上稳定的CAD患者.
- 使用VerifyNowTM ARU和PRU试验测量了基线血小板功能.
- 在每天口服0.5毫克的COLC服用14天后,重新评估了血小板功能.
主要成果:
- 在COLC后的ARU (463比436,p=0.485) 或PRU (210比199,p=0.581) 平均得分中没有观察到统计学意义上的变化.
- 患有阿司匹林耐药性的患者比例从27.3%降至13.6%,克洛皮多格雷尔耐药性从50%降至45.5%,尽管不显著.
- 两名患者报告了轻微的胃肠道不适;没有发生严重的不良事件.
结论:
- 在DAPT.稳定的CAD患者中,素 (COLC) 给药没有显著改变血小板活性 (ARU和PRU).
- 这项试点研究表明,COLC可能不会在临床上影响阿司匹林和克洛皮多格雷尔在这个人群中的疗效.
- 需要进一步的研究来证实在更大的队列中这些探索性发现.
