Abstract:
Objective: To explore clinical features of acute myocardial infarction (AMI) caused by left main (LM) coronary artery lesions and to study the effect of percutaneous coronary intervention (PCI) in relevant patients. Methods: A total of 3514 AMI patients received coronary angiography (CAG) in our hospital from 2000-01 to 2015-12 were studied, those including 36 of infarct-related artery (IRA) as LM. There were 28/36 patients received PCI and 8 received CABG. The clinical features and outcomes in 28 LM disease patients were investigated. Results: The patients included 5 female and 23 male at the mean age of (66.5±8.32) years. There were 16 patients with ST-segment elevation myocardial infarction (STEMI) and 12 with NSTEMI; 21 received primary PCI and 7 had elective PCI; there were 16 patients suffered from cardiac shock at admission. The procedural success rate was 82.1% and the in-hospital mortality was 35.7% (10/28). During (66.1±35.2) months follow-up period, 3 patients had re-NSTEMI and 1 of them received PCI again, 3 patients died. No event survival rate was 66.7%. Conclusion: PCI is feasible for treating AMI patients caused by LM lesions, the in-hospital survival rate was 64.3%; while the MACE occurrence rate during long-term follow-up period has been high.
