ABSTRACT
<p><b>OBJECTIVE</b>The effects of primary percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI) induced by left main (LM) artery occlusion were analyzed retrospectively in this study.</p><p><b>METHODS</b>A total of 1343 consecutive AMI patients who underwent primary PCI between January 1995 and December 2004 were retrospectively studied.</p><p><b>RESULTS</b>LM occlusion or severe stenosis were found in 11 patients [all male, mean age (56.4 +/- 9.2) years (range 43-70 years)], cardiogenic shock was overt in 6 patients. Primary PCI were performed under the assistance of intra-aortic balloon pump (IABP) in these patients [8 stent implantation, 3 balloon dilation and 2 necessitating emergency CABG after balloon dilation]. In-hospital mortality was 45.5% (5/11). Three-month follow-up were made in all survivals (6/11). Analysis showed good collateral circulation flow from right coronary artery to left coronary artery was existed in all survival cases before PCI.</p><p><b>CONCLUSION</b>Prognosis of AMI patients with LM artery obstruction or severe stenosis was poor. Patients with pre-existed collateral circulation before primary PCI and IABP had a better clinical outcomes.</p>
