-13-a Study of Total Coronary Occlusion Occurring Between Two Angiographies Based on a Comparison of Patients With and Without Myocardial Infarction
Year: 1986
Type: article
Abstract: This study was attempted to clartfy the efficacy of PTCA in acute stage of myocardial infai'ction for the improvement of waU motion in chronic stage.In 27 cases of ncute antereseptal myocardial lnfnrction (successful corenary thrombolysiB (CT) 11 cases and successful Cl'+ji'1'CA 16 cases), the infarct size and eardiac perforanance in chronic stage were examined.As an index of infarct size, S ab"urmally contoacting segment C%Acs}, total CK pelease (ZCK) were used, Anterior regional ejection fraction (REF) was provided for an ipdex of chronic left venti,tcular perfornnanee.Results were : 1) The %ACS was sigmifi:antly smal]er in the CT+PTCA group than in the CT group.2) Tbe residual stenosis and the elapsed time had no correlation with the fACS and the REF.]) The difference hetween the % stenosis beCore and after PTCA had significant]y positive correlatjon with the %ACS and negative correlation with the REF.Thus the degree ol' di]atj.on in PTCA related tbe infarct size and the ]ert ventricu]ar perfor'mance.
