对126例陈旧性心肌梗塞(OMI)者的心室晚电位(VLP)预后意义做了前瞻性研究.经14±5月的随访,结果示:VLP阳性率为30.16%;发生室性心律失常事件(简称事件)者共15例;其中VLP阳性者12例,表明VLP阳性者日后发生事件远比VLP阴性者高(分别为31.58%和3.4%,P<0.001).VLP阳性预测事件的敏感性为80%,特异性为76.58%,准确率为31.58%.而VLP阴性的预测准确率为98.20%.因此认为,VLP检测对预测OMI者事件的发生有重要的临床意义.
Prospective study on the prognostic significance of ventricular late potentials (VLP) in 126 elderly patients with myocardial infarction (OMI) .After 14 ± 5 months of follow-up, the results showed that: VLP positive rate was 30.16%; ventricular arrhythmia occurred (Incident) were 15 cases, of which 12 cases were positive for VLP, indicating that the incidence of VLP positive events in future was far higher than those with negative VLP (31.58% and 3.4%, respectively, P <0.001) .VLP positive predictive value The specificity was 76.58% and the accuracy rate was 31.58%, while the negative predictive rate of VLP was 98.20% .Therefore, it is considered that VLP detection has important clinical significance in predicting the occurrence of OMI events.
