Alagiakrishnan K, Beitel JD, Graham MM, Southern DA, Knudtson ML, Ghali WA, Tsuyuki RT for the APPROACH Investigators. Relation of T-Axis Abnormalities to Coronary Artery Disease and Survival after Cardiac Catheterization. Am J Cardiol 2005 Sep 1; 96:639-642.
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.
