摘要 目的:探讨低分子肝素(LMWH)联合曲美他嗪(TMZ)对不稳定性心绞痛(UAP)各危险层的疗效。方法:采用Braunwald法对UAP分级,将142例UAP患者随机分为I级46例,II级54例,III级42例。将各级患者随机分成联合组、肝素组和常规组,在常规抗心绞痛疗法基础上,肝素组加用LMWH,联合组加用LMWH和TMZ,其中LMWH 0.4ml(4100IU),q12h IH,7 ̄10天,TMZ 60 ̄120mg/d,疗程30天。观察3组临床疗效及治疗后30天的心脏事件(心源性死亡,心肌梗死,顽固性心绞痛)。结果:联合组总有效率为93.62%,肝素组89.13%,常规组69.39%,前两组疗效与常规组比较差异有统计学意义(P<0.05)。对I级患者,心脏事件无统计学意义。II级患者在顽固性心绞痛事件上联合组及肝素组发生率明显降低(P<0.05)。III级患者在心肌梗死、顽固性心绞痛上联合组及肝素组发生率均低于常规组(分别为P<0.01,P<0.05)。3组病例均未发生心源性死亡。结论:联合组和肝素组在治疗UAP中均有良好的疗效,但联合组又优于肝素组,两药联用有协同作用。对UPA II级I、II级患者,须给予LMWH辅TMZ强化治疗,可减少患者远期的急性心血管事件。
