Clinical Outcomes of Percutaneous Coronary intervention in patients with Acute Myocardial Infarction with More Branches of Lesion Coronary

Objective To evaluate the Clinical outcomes of the revascularization in the patients with acute myocardial infarction with more branches of lesion coronary by primary percutaneous coronary intervention(PCI).Methods From January 2001 to January 2005,154 patients with acute myocardial infarction with more branches lesion coronary were treated by PCI.80 of the patients were only treated culprit coronary which induced the acute myocardial infarction by stent implantation,others were treated in all the branches of lesion coronary,before and after PCI all the patients were treated by drugs similarly,months follow-up was made in all the patients.Results There was no significant difference between the two groups in general things before treatment、drugs treatment in follow-up period and long stents implantation;in the group only treated the culprit coronary diabetes mellitus rate was significant higher than the other group,ST segment elevation rate was significant lower,patients with LVEF0.40 and blood creatinine≥116μmol/L after PCI were significant more;The cardiac incidences such as unstable angina pectoris、myocardial infarction and coronary artery reconstruction were significant more in the group treated the culprit coronary(all P0.05);Cardiac death in the group treated the culprit coronary slightly more(P0.05),no-cardiac death was significant more(P0.05).Conclusion The clinical outcomes is poor in the Patient with acute myocardial infarction with more branches lesions coronary only treated the culprit coronary by primary PCI.No-cardiac death rate in the group treated the culprit coronary increased.Major cause of nocardiac death is nephritic induced by diabetes mellitus.
