阿司匹林是目前研究和应用最广泛的抗血小板药物 ;沙纳吡啶 (ｔｈｉｅｎｏｐｙｒｉｄｉｎｅ)的衍生物 (噻氯匹啶和氯吡格雷 )是另一类作用机制不同于阿司匹林的抗血小板药。作者拟通过大量的随机病例系统回顾、比较沙纳吡啶和阿司匹林在防止血管病高危患者血管病发生的安全性和 Aspirin is currently the most widely researched and most widely used antiplatelet drug; derivatives of thienopyridine (ticlopidine and clopidogrel) are another type of antiplatelet drug whose mechanism of action is different from that of aspirin. The authors intend to review a large number of randomized case-by-case systems to compare the safety of shapiride and aspirin in preventing vascular disease in high-risk patients with vascular disease and
