title: Relation of T-axis abnormalities to coronary artery disease and survival after cardiac catheterization.
abstract: We investigated the association of an abnormal T axis with angiographic indicators of coronary artery disease and mortality. In univariate analysis, no significant association was observed between an abnormal T axis and extent of coronary artery disease (p = 0.928). An abnormal T axis was a significant predictor of overall mortality (p = 0.035) for death at any time in our unadjusted survival analysis, and a trend toward poorer survival persisted after adjustment for clinical covariates.
