T波电交替试验预测急性脑出血患者预后的意义

Role of T-wave alternans testing in predicting prognosis of patients with acute cerebral hemorrhage

目的探讨T波电交替(TWA)试验预测急性脑出血患者预后的意义。方法回顾性分析53例急性脑出血患者的临床资料,TWA阳性(A组)15例和TWA阴性(B组)38例,比较两组住院时间、住院期间死亡率和神经功能缺损评分,分析预后的独立危险因素。结果 A组住院时间长于B组[(24.1±4.6)d vs.(21.8±2.5)d](P<0.05);A组神经功能缺损评分减少7例,少于B组的30例(P<0.05)。脑出血量和TWA均为影响急性脑出血患者预后的独立危险因素[(OR=0.54,95%CI:0.35-0.86,P<0.01)和(OR=0.15,95%CI:0.03-0.78,P<0.05)]。结论急性脑出血合并TWA可能意味预后较差。

Objective To evaluate the role of T-wave alternans（TWA） testing in predicting the prognosis of patients with acute cerebral hemorrhage （ACH）. Methods Clincal data of 53 ACH patients were retrospectively analyzed. Hospital stay, inhospital mortality and neurological deficit scores were compared between groups of A（TWA positive, 15 cases） and B（TWA negative, 38 cases）. Independent risk [actors for prognosis were analyzed. Results Hospital stay in group A was longer than that in group B[（24. 1±4. 6） days vs. （21.8±2. 5） days] （P〈0. 05）. There was 7 cases in group A with a decrease of neuro!ogical deficit scores, which was less than 30 cases in group B （P〈0. 05）. The amount of cerebral hemorrhage and TWA were the independent risk factors for prognosis in ACH patients[（OR=0. 54,95%CI： 0. 35-0. 86,P（0. 01）and（OR=0.15,95%CI：0. 03- 0. 78,P〈0. 05）]. Conclusion ACH with TWA may mean a poor prognosis.
