Abstract:
Objective To study mortality of acute myocardial infarction caused by acute left main coronary artery occlusion.The objectives of this analysis were to determine the effect of primary PCI and the impact of cardiogenic shock on acute myocardial infarction caused by acute left main coronary artery occlusion.Methods From 1999 to 2005,of 752 consecutive patients with acute myocardial infarction,16 patients had acute left main coronary artery occlusion with TIMI flow≤2.All patients were given primary PCI.Results Of these 16 patients,9(56.25%)died in hospital,and 7(43.75%)discharged.In the survival group reperfusion was successful in 100% of patients,as opposed to 44.44% in the mortality group(P=0.019).Cardiogenic shock was overt in 12(75.00%)patients,42.86% of the survival group and 100% of the mortality group(P=0.020).Shock patients had higher in-hospital mortality than stable patients(75 % vs 0%,odds=4.0,95%CI 1.50~10.66,P=0.019).Conclusion Patients presenting with AMI caused by acute left main coronary artery occlusion and cardiogenic shock have poor survival regardless of primary PCI.Nevertheless,primary PCI is a feasible and effective procedure,and it may save lives in this clinical setting.
