摘要
目的 探讨对血栓形成高度敏感的血栓前体蛋白 (thrombus precursor protein,TPP) ,在伴有心房颤动(atrial fibrillation,Af)的心脏机械瓣膜置换术患者术后抗凝监测中的意义。 方法 将 90例二尖瓣机械瓣置换术后抗凝患者根据是否伴有 Af分为 Af组 (4 5例 )、窦性心律组 (SR组、4 5例 ) ,2 0例非心瓣膜疾病的其他心脏病患者作对照 (对照组 ) ,观察比较三组的血浆 TPP浓度和国际标准化比率 (International Norm alized Ratio,INR) ,根据血浆TPP浓度将 Af患者分为三组 ,分析、比较其 INR和血浆 TPP浓度。 结果 心瓣膜置换术后 SR组和 Af组的血浆TPP浓度低于正常对照组 (P<0 .0 5 ,<0 .0 1) ,INR则高于对照组 (P<0 .0 1) ;Af组的血浆 TPP浓度高于 SR组 (P<0 .0 5 ) ;Af组患者的 INR存在与血浆 TPP浓度和患者临床表现不相符合的情况。 2 8例 Af患者的血浆 TPP浓度低于6 μg/ m l(4 .2 9± 0 .75 μg/ ml) ,血栓栓塞危险性低 ,无出血现象 ,其抗凝效果满意 (INR2 .10± 0 .73)。该组患者的 INR95 %可信区间为 1.90~ 2 .30。 结论 伴有 Af的心瓣膜置换患者可能有更高的血栓栓塞危险 ,INR在 1.90~ 2 .30之间 ,且血浆 TPP浓度在 2 .84~ 6 .0 0 μg/ m l之间可能是 Af心瓣膜置换患者抗凝治疗的适宜范围
