despite a similar degree of initial ischemia ( sigma st ) , infarct size was smaller in the 11 patients with anterior infarction and subtotal occlusion than in the 9 patients with anterior infarction and total occlusion when measured by peak serum creatine kinase ( 2114 +/- 1192 u/l vs. 3653 +/- 1059 u/l , p less than 0.02 ) , qrs score ( 5.0 +/- 2.7 vs. 9.6 +/- 3.5 , p less than 0.01 ) , sigma q ( 3.25 +/- 2.74 mv vs. 5.92 +/- 3.56 mv , p less than 0.10 ) , sigma r ( 4.36 +/- 1.25 mv vs. 2.16 +/- 0.91 mv , p less than 0.001 ) , global left ventricular ejection fraction ( 45.0 +/- 12.2 % vs. 33.4 +/- 6.7 % , p less than 0.05 ) , and infarct segment ejection fraction ( 40.4 +/- 8.2 % vs. 30.3 +/- 5.4 % , p less than 0.05 ) .
