[Management of patient with acute myocardial infarction due to left main trunk obstruction].
Between April 1995 and March 1998, we experienced 13 cases of Acute Myocardial Infarction due to Left Main Trunk Obstruction (LMT-AMI). Two cases died before emergent intervention. Eight cases underwent emergent intervention (Plain Old Balloon Angioplasty (POBA) in five cases, Stenting in 3 cases); 2 cases died of acute occlusion of POBA site, 1 case survived by only POBA, and the other 5 cases underwent following Coronary Artery Bypass Grafting (CABG). 3 cases underwent only CABG with stable hemodynamics condition by Intraaortic balloon pumping (IABP) support. In a result, seven of eight CABG cases survived. Emergent stenting made the hemodynamics before CABG stable, and six-month's follow up angiogram showed occluded bypass grafts and patent stented sites in two of three cases. The combination therapy of emergent stenting and CABG will have to be evaluated in future.
