OBJECTIVE: To evaluate the prognostic value of specified vectorcardiographic data obtained during the first hours of ST-elevation @entity583 for cardiac outcomes up to 5 years. DESIGN: Three hundred and five @entity1 with ST-elevation @entity583 and @entity662 for less than 12 h were monitored with continuous vectorcardiography. RESULTS: All @entity1 had follow-up for at least 1 year. The mortality was 5.9% at 30 days and 10.8% at 1 year. The estimated 5-year mortality was 24%. A total of 7.9% had recurrent @entity1188 at 30 days and 11.2% at 1 year. Recurrent @entity1188 occurred in 12.1% at 30 days and in 19.7% at 1 year. The presence of ST-VM (plateau) >or= 125 microV was highly predictive of the combined endpoint @entity204 or recurrent @entity1188 at 1 year, OR 2.69 (95% CI 1.39-5.23). Multivariate analysis showed that age >or=75 years, @entity583 , and the presence of ST-VM (plateau) >or= 125 microV, were independently associated with increased risk of recurrent @entity1188 at 1 year and with @entity204 at 5-year follow-up. A start value of ST-VM <or=100 microV identified a group of @entity1 with low risk of @entity204 or re- @entity1188 within 1 year. CONCLUSION: Continuous vectorcardiography during the first hours after thrombolytic treatment of @entity1 with ST-elevation @entity583 provides important prognostic information. A new vectorcardiographic variable, ST-VM (plateau), identifies a group of @entity1 with increased risk of recurrent @entity1188 . As well, @entity1 with low risk of recurrent @entity1188 were identified by low start values of ST-VM.

Early vectorcardiographic monitoring provides prognostic information in XXXX with ST-elevation @entity583 .
