Sažetak
Background: Cardiogenic shock (CS) is a state of critical end-organ hypoperfusion characterized by high early mortality. In 2015, the CardShock score was developed as a risk prediction tool for mortality in patients with cardiogenic shock. Purpose: 1) To validate the CardShock score for risk stratification in our population ; 2) To assess whether a parsimonious model may perform equally well for prediction of short-term mortality in patients (pt) with CS. Methods: Clinical and laboratory data of 165 patients admitted for CS to two Italian ICCU during 4 years (2013–2016) were retrospectively examined. CardShock additive score was calculated for each pt. Variables significantly associated with in-hospital mortality by univariable logistic regression were entered in a multivariable model. C- statistic and Hosmer- Lemeshow test were used to assess the model predictive accuracy and goodness of fit. Results: A studied population (69±12.7 years, 69% men) had a mean MAP (mean arterial pressure) of 60±16 mmHg, severe LV dysfunction (left ventricular ejection fraction – LVEF: 28±11%), and moderate renal failure (eGFR (CKD- EPI): 51.1±27.2 mL/min/1.73m2). Serum lactates averaged 6.6±5.3 mmol/L. The chief admission diagnosis was acute coronary syndrome (64% STEMI and 11% NSTEMI). A 73%of pt received intra-aortic balloon pump (IABP). The in- hospital mortality was 47%. Per established CardShock variables, a multivariable analysis (Table 1) showed that patient' age, serum lactates and LVEF at admission had the highest statistical correlation with mortality outcomes in our sample. Therefore, a new risk score composed of these three variables that stratified the population in three mortality risk classes was created. Our results show that this risk score performed better in a prediction of in-hospital and 30-day mortality (AUC 0.82 95% CI 0.76–0.89 and AUC 0.79 95% CI 0.71–0.86, respectively) than the CardShock score (AUC 0.72 (95% CI 0.64–0.79), in our cardiogenic shock population (Figure 1). Conclusions: The use of a simplified score is equally or even more reliable than CardShock risk score for the prediction of in-hospital mortality in pt with CS. This simplified score can be calculated in few minutes and is highly accurate, allowing to decide the best treatment options without further delay.
