Lancet:不是所有疑似急性冠脉综合征患者都需要住院治疗

2015-10-08 cuiqian译 MedSci原创

疑似急性冠脉综合征是紧急入院最常见的原因,并成为了医疗资源的一个很大的负担。确定低危患者适合立即出院的策略有很大的益处。研究人员在苏格兰做了一项前瞻性队列研究,纳入了6304例连续登记的疑似急性冠脉综合征患者,他们来自于四个二级和三级医院。研究人员采用了高灵敏度的心肌肌钙蛋白I法测定血浆肌钙蛋白浓度。在推导和验证队列中,研究人员评估了标志心肌梗死为主要结果的一个范围内的肌钙蛋白浓度,或随后的心肌梗

研究人员在苏格兰做了一项前瞻性队列研究,纳入了6304例连续登记的疑似急性冠脉综合征患者,他们来自于四个二级和三级医院。研究人员采用了高灵敏度的心肌肌钙蛋白I法测定血浆肌钙蛋白浓度。在推导和验证队列中,研究人员评估了标志心肌梗死为主要结果的一个范围内的肌钙蛋白浓度,或随后的心肌梗死或心脏猝死结果。

在推导队列中的4870例患者中的782(16%)例患者有指数心肌梗死,后期32(1%)例患者再次出现心肌梗死,75(2%)例患者在30天时因心脏病死亡。在上面提到的无心肌梗死的患者中,3799例患者中的2311(61%)例患者的肌钙蛋白浓度为小于5ng/L,主要结果的阴性预测值为99.6%,(95%Cl为99.3-99.8)。阴性预测值在各组中是一致的,这些组是通过年龄,性别,危险因素,和以往的心脑血管疾病史进行分层的。在两个独立的验证队列中,1061例患者中的594(56%)例患者肌钙蛋白浓度低于5ng/L,总的阴性预测值为99.4%(98.8-99.9)。在1年时,在心肌梗死和心源性死亡方面,这些患者比那些肌钙蛋白浓度为5ng/L及以上的患者风险低(0.6% vs 3.3%;调整后的危险比0.41,95%Cl 0.21-0.80,P<0.0001)。

低血浆肌钙蛋白浓度确定了心脏病低风险的三分之二的患者可以出院。这种方式的实现可以大大减少住院的患者,这主要对患者和医疗保健提供者带来了益处。
