    Abstract:
    OBJECTIVE: To evaluate the clinical outcomes of patients with acute myocardial infarction (AMI) complicating cardiogenic shock underwent various treatments. METHODS: From January, 2002 to May, 2007, 47 AMI patients with cardiogenic shock were treated in our department by optimal medication (dopamine, epinephrine, norepinephrine, etc.), intra-aortic balloon pump (IABP), mechanical ventilation when indicated, percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG). Outcome and factors related to mortality for these patients were analyzed in this retrospective study. RESULTS: Besides optimal medication and IABP in all patients, 31 patients underwent PCI (66.0%), 6 patients received emergency CABG (12.8%). The overall in-hospital mortality rate was 36.2% (17/47), 6 patients (14.9%) died before coronary revascularization and 11 patients (21.3%) died after revascularization. Nine patients died of pump failure and 8 patients died of renal and (or) respiratory failure. Regression analysis showed that acute renal failure (r = 0.734, P = 0.000), acute respiratory failure (r = 0.606, P = 0.000) and diabetes (r = 0.372, P = 0.012) were positively related to in-hospital mortality. CONCLUSION: Despite improvements in treatment options for AMI patients complicating cardiogenic shock, in-hospital mortality remained high, especially for patients complicating further with acute renal failure and acute respiratory failure.
