Objective To assess the predictive value of three biomarkers for mortality in ST-segment elevation myocardial infarction (STEMI) with cardiogenic shock. Background STEMI complicated by cardiogenic shock accounts for the majority of STEMI related deaths. Patients with STEMI and hyperglycemia, anemia or kidney dysfunction on admission have a poor prognosis. As data on the combination of those three established predictors of mortality are sparse in STEMI with cardiogenic shock, the objective of the current study was to investigate their predictive value in STEMI patients with cardiogenic shock. Methods and results Between 1997 and 2005, a total of 3038 patients presented with STEMI and were treated with percutaneous coronary intervention (PCI). On admission 292 patients presented with cardiogenic shock. Glucose, hemoglobin and creatinine clearance were available in 183 out of 292 patients. Overall 1-year mortality was 34%. In multivariate logistic regression analysis, only glucose remained a strong independent predictor for mortality. The odds for mortality increased by 11% for each 1 mmol/l increase in glucose (OR 1.11, 95% CI 1.02-1.21, P = 0.013). Conclusion Hemoglobin and creatinine clearance bear no prognostic value. Only admission glucose levels strongly and independently predict 1-year mortality in STEMI patients with cardiogenic shock and treated with PCI.
