Prognostic value of ST-segment resolution-when and what to measure.

摘要: Aims Analyses of ST-segment resolution during acute myocardial infarction has, recent years, challenged coronary angiography as gold-standard for predictingmyocardial reflow and future risk. We have previously reported that continuous ST-monitoring can be done accurately in the clinical setting. now set out to compare prognostic value suggested cut-offs ST-segmentresolution, determine times measure these. Methods results analysed 752 patients with ST-elevation infarction, from second Assessment Safety Efficacy a New Thrombolytic (ASSENT 2) ASSENT-PLUS studies, either vectorcardiography or 12-lead ST-monitoring. All analyses were made blindly by two independent observers. Times 20, 30, 50 70% examined relation 30-day mortality. The optimal cut-off was found 50%, measured at 60min. could hereby identify large low-risk group, 40% population, only 1.4% mortality. Furthermore, 88% deaths correctly predicted within 1h observation treatment. Conclusion Continuous yields important information after 60min should used very early-risk stratification these patients.
