Objective To investigate the relationship between hypoproteinemia and in-hospital sudden cardiac death(SCD)in patients with acute myocardial infarction(AMI).Methods Logistic regression analysis was used to evaluate the risk factors for SCD and Spearman correlation analysis was used to investigate the correlation between the risk factors and SCD in 84 AMI patients with in-hospital SCD(SCD group)and 84 AMI patients admitted at the same period(control group).Results The left ventricular ejection fraction(LVEF)...
