The long-term prognostic value of the Q wave criteria for prior myocardial infarction recommended in the universal definition of myocardial infarction. Journal of electrocardiology Perino, A. C., Soofi, M., Singh, N., Aggarwal, S., Froelicher, V. 2015; 48 (5): 798-802

Abstract

We sought to characterize the prognostic value of the third universal definition of myocardial infarction (UDMI) and =40msec Q wave criteria.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.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.The UDMI Q wave criteria do not provide an advantage over =40msec Q waves at predicting CV death.
