Abstract:
Objective To study clinical data of patients with acute myocardial infarction (AMI) induced by left main (LM) artery occlusion,and to find out the clinical characteristics.Method From Janurany 1995 to May 2006,there were 15 patients with AMI related with LM obstruction from 1793 AMI patients,in whom primary PCls were performed.All patients were male with a mean age of (60.6?10.4) years old (ranging from 43 to 85 years old).The clinical and interventional data were retrospectively analyzed.Results Cardiogenic shock occurred in 10 patients at admission.Primary PCls were performed with intraaortic balloon pump (IABP) in all patients.Nine patients died during short follow-up,and the mortality was 60%.Three-month follow-up was made in the all survival patients,and one patient died after 4 years.Analysis showed good collateral circulation flow from right coronary artery to left coronary artery before operation affected the short-term prognosis.Conclusions AMI related with left main artery obstruction was critically fatal with high occurrence of cardiogenic shock and high mortality.Prognosis differs at,cording to different degree of collateral circulation.Primary PCI with IABP provides a promising strategy to improve clinical outcomes.
