Statin-treated patients presented median cTnI peak values similar to controls ( 3.9 [ 0.6-12 .8 ] vs 3.5 [ 1.2-11 .9 ] ng/mL , respectively ; P = .60 ] ; no differences were found between the 2 groups in cTnI and creatine kinase-MB values at any time point , in either preangiography and postangiography peak values or their cumulative release .
