After adapting a threshold 40ms for inferior and 20ms for lateral/apical MI in all patients ( n = 3065 ) with any measureable Q-wave we found hazard ratios ( HR ) for mortality ( HR : 2.44 , 95 % confidence interval ( CI ) ( 1.54-3 .85 ) , p < 0.001 ) and the composite ( HR : 2.32 , 95 % CI ( 1.70-3 .16 ) , p < 0.001 ) .
