Table 2.

Results of multivariate analysis of risk factors for individual markers of myocardial injury including QT prolongation, T-wave inversion, Troponin leak (>= 0.1), depressed ejection fraction (less than 55%), and wall motion abnormalities. P values meeting statistical significance (p < 0.05) are shown in bold.^a
