tokens: RESULTS : Patients in Group A had a higher incidence of posterolateral wall motion abnormalities ( p < 0 . 001 ) on radionuclide ventriculography , a larger infarct area ( as evidenced by higher peak creatine kinase levels ) ( p < 0 . 02 ) and a lower left ventricular ejection fraction ( LVEF ) at hospital discharge ( p < 0 . 008 ) than those in Group B .
