Background ST-segment elevation myocardial infarction (STEMI) complicated with cardiogenic shock (CS) remains as an unresolved condition causing high morbidity and mortality despite advances in medical treatment and coronary intervention procedures. In the current study, we evaluated the predictors of in-hospital mortality of STEMI complicated with CS. Methods In this retrospective study, we evaluated the predictive value of baseline characteristics, angiographic, echocardiographic and laboratory parameters on in-hospital mortality of 319 patients with STEMI complicated with CS who were treated with primary percutaneous coronary intervention. Patients were divided into two groups consisting of survivors and non-survivors during their index hospitalisation period. Results The mortality rate was found to be 61.3% in the study population. At multivariate analysis after adjustment for the parameters detected in univariate analysis, chronic renal failure, Thrombolysis In Myocardial Infarction (TIMI) post percutaneous coronary intervention (PCI) <= 2, plasma glucose and lactate level, blood urea nitrogen level, Tricuspid Annular Plane Systolic Excursion (TAPSE) and ejection fraction were independent predictors of in-hospital mortality. Conclusions Apart from haemodynamic deterioration, angiographic, echocardiographic and laboratory parameters have an impact on in-hospital mortality in patients with STEMI complicated with CS.
