ABSTRACT
BACKGROUND:
We sought to characterize the prognostic value of the third universal definition of myocardial infarction (UDMI) and ≥40msec Q wave criteria.METHODS:
We evaluated hazard ratios (HR) with 95% confidence intervals (CI) for cardiovascular (CV) death for computerized Q wave measurements from the electrocardiograms of 43,661 patients collected from 1987 to 1999 at the Palo Alto VA. There were 3929 (9.0%) CV deaths over a mean follow-up of 7.6 (±3.8) years.RESULTS:
The risk of CV death for Q waves ≥40msec in any two contiguous leads in any lead group was equivalent to or higher than that for contiguous UDMI Q waves, with HR 2.44 (95% CI 2.15-4.11) and HR 2.42 (95% CI (2.18-3.42), respectively.CONCLUSIONS:
The UDMI Q wave criteria do not provide an advantage over ≥40msec Q waves at predicting CV death.Palavras-chave
