The Analysis Of Factors That Influence AMI Patients' Prognosis

Objective: To investigate the death state of in-hospital AMI patients and analyze the risk factors associated with in-hospital mortality, one-year and two-year mortality in AMI patients.Material and Methods: 133 AMI cases were collected from August 2006 to August 2007 in Beijing Hospital. Enrolled dead records and retrospectively analyzed the factors associated with in-hospital mortality. 122 survivors were followed up for 1～2 years. We calculated the one-year and two-year mortality; analyzed the risk factors associated with the mortality. All results were performed using SPSS version 11.5.Results: In-hospital mortality of AMI was 8.3%(11/133). One-year mortality was 12. 1%(16/132). Two-year mortality was 20. 9%(18/86). The main characters of in-hospital death included elder age, ventricular systolic dysfunction (low LVEF), renal dysfunction, more shock onset, less treatment withβ-blocker and PCI. Logistic regression analysis demonstrated that age, high Killip classification, low use rate ofβ-blocker were independent risk factors of in-hospital mortality in AMI patients. Elder age, ventricular systolic dysfunction(low LVEF), high Killip classification, more shock onset , less treatment of PCI, associated with one-year and two-year mortality. Logistic regression analysis showed age, high Killip classification were the independent risk factors of one-year mortality of AMI patients.Conclusions: Age, high Killip classification, low use rate ofβ-blocker maybe the independent risk factors of in-hospital mortality in AMI patients. Age, high Killip classification maybe the independent risk factors of one-year and two-year mortality in AMI patients.
