patients with anterior infarction had a substantially worse in-hospital and follow-up clinical course compared with those with inferior infarction , evidenced by a larger infarct size ( 21.2 versus 14.9 g eq/m2 creatine kinase , mb fraction [ mb ck ] , p less than 0.001 ) , lower admission left ventricular ejection fraction ( 38.1 versus 55.3 % , p less than 0.001 ) and higher incidence of heart failure ( 40.7 versus 14.7 % , p less than 0.001 ) , serious ventricular ectopic activity ( 70.2 versus 58.9 % , p less than 0.05 ) , in-hospital death ( 11.9 versus 2.8 % , p less than 0.001 ) and total cumulative cardiac mortality ( 27 versus 11 % , p less than 0.001 ) .
