A study of the treatment of delayed emergency percutaneous coronary intervention on the prognosis of patients with ST elevation acute myocardial infarction / 重庆医学

ABSTRACT

Objective To compare the prognosis of ST elevation acute myocardial infarction(STEMI) of delayed emergency per‐cutaneous coronary intervention(PCI) and elective PCI following the thrombolysis with reteplase ,and to investigate the clinic value of the former solution .Methods One hundred and twenty STEMI patients were reviewed retrospectively and were divided into 2 groups according to PCI .Eighty two cases were divided into emergency groupthrombolysis with reteplase offered within 6h was followed by elective PCI;38 cases were divided into delayed groupPCI was done after 12-24 h after ATEMI′occurring .The clini‐cal features and CTG changes were recorded ,TIMI class of IRA was conducted before and after PCI ,and their prognosis were com‐pared .Results There was no statistical differences in the class of thrombolysis of myocardial infarction(Class 0 -1 ,2 -3) of in‐farction relative artery (IRA)(4 .88% ,95 .12% vs .5 .26% ,94 .74% ) after PCI(P>0 .05) .There was no statistical difference in LVEF ,LVEDVI and LVESVI 3 months after attack between two groups(P>0 .05) .There was statistical difference in the severe cardiac failure and malignancy arrhythmia between two groups(P0 .05) .Conclusion Delayed emergency PCI to remove the ob‐struction in the coronary artery has no significant difference with elective PCI following thrombolysis in the incidence of composite end point events in STEMI .
