Objectives: The mortality of patients with cardiogenic shock (CS) complicating ST elevation acute myocardial infarction (STEMI) remains high, despite early revascularization. Current knowledge of predictors of death is limited. Background: The pathophysiologic understanding of CS after acute myocardial infarction has shifted from a mere hemodynamic disorder to a more complex approach including imbalance in metabolic functions. Methods: In 45 consecutive patients (71.4 ± 13 years) with CS complicating STEMI treated with primary percutaneous coronary intervention (PCI) serum levels of lactate, glucose and uric acid on coronary care unit (CCU) admission were measured. The end-point was in-hospital death. Results: The following parameters, on CCU admission, were univariate predictors of in-hospital mortality: serum glucose > 200 mg/dl (OR = 11.3, p = 0.002), serum creatinine > 1.5 mg/dl (OR = 12.7, p = 0.003), uric acid > 6.5 mg/dl (OR = 6.7, p = 0.016), lactate > 6.5 mmol/l (OR = 54, p <0.0001), age ≥ 75 years (OR = 8.5, p = 0.002), history of hypertension (OR = 8.3, p = 0.003) and TIMI flow post PCI ≤ 2 (OR = 12.9, p = 0.02). At multivariate analysis, after adjustment for sex, age, hypertension and diabetes, lactate > 6.5 mmol/l and TIMI flow post PCI ≤ 2 were still independent predictors of in-hospital mortality (OR = 295, p = 0.01; OR = 19.5, p = 0.04, respectively). Conclusions: Hyperlactatemia, hyperglycemia and increased levels of uric acid on CCU admission are univariate predictors of in-hospital death. Moreover, at multivariate analysis, hyperlactatemia (> 6.5 mmol/l) is an independent indicator of in-hospital death in CS patients complicating STEMI.
