Prognostic factors for the early cardiogenic shock in patients with myocardial infarction without shock signs on admission

Aim . To evaluate the clinical, hemodynamic, and paraclinical characteristics of patients with myocardial infarction (MI) who developed stage B or higher cardiogenic shock (CS) within 48 hours of admission in the absence of shock signs at admission, and to identify factors associated with mortality. Material and methods. This retrospective analysis included 60 patients. The primary endpoint was inhospital death. Univariable and multivariable logistic regression analyses were used. Results . Mortality in this cohort of patients was 55%. Independent predictors of mortality in the multivariable model were type 2 diabetes (odds ratio (OR) 149,6; p=0,001) and higher systolic blood pressure on admission (OR 1,08 per 1 mm Hg; p=0,015). Furthermore, achieving optimal reperfusion (Thrombolysis In Myocardial Infarction (TIMI) 3 was an independent protective factor (OR 0,009; p=0,015). The area under the ROC curve for the model was 0,70. Conclusion . In patients with MI followed by CS, signs of Society for Cardiovascular Angiography and Interventions (SCAI) stage A may be detected already upon admission. These parameters have prognostic significance and can be used for early mortality risk stratification and selection of monitoring strategies.
