Does the Intermountain Risk Score predict short- and long-term mortality better than the SYNTAX score II in patients with STEMI complicated by cardiogenic shock?
The Intermountain Risk Score is a useful prognostic tool that outperforms the SYNTAX score II for predicting short- and long-term mortality in patients with STEMI complicated by cardiogenic shock.
BACKGROUND: There is a lack of current research examining the predictive value of the Intermountain Risk Score (IMRS) in patients with ST-segment elevation myocardial infarction (STEMI) caused by cardiogenic shock. Therefore, the purpose of this research was to investigate the ability of IMRS to predict short- and long-term mortality in patients with cardiogenic shock triggered by STEMI. METHODS: The participants included 492 consecutive cardiogenic shock patients who underwent primary percutaneous coronary intervention following STEMI. The patients were separated into two groups depending on their survival status. The groups' baseline characteristics, laboratory data, echocardiographic variables, and risk assessments were then compared. Next, the IMRS score was tested for its ability to predict both short- and long-term mortality. In order to assess its accuracy, the prognostic value of the IMRS was also compared that of the SYNTAX score II (SSII). RESULTS: After adjustment for the characteristics in the univariable study, multivariable Cox regression analysis indicated that the IMRS and SSII were both independently associated with short- and long-term mortality in STEMI patients with cardiogenic shock. However, the receiver operating characteristic curves indicated that the IMRS outperformed the SSII in terms of predicting both short- and long-term mortality. CONCLUSION: This preliminary investigation showed that IMRS can predict both short- and long-term mortality in individuals with STEMI accompanied by cardiogenic shock.
İlker et al. (Wed,) conducted a observational in STEMI with cardiogenic shock (n=492). Intermountain Risk Score (IMRS) vs. SYNTAX score II (SSII) was evaluated on Short- and long-term mortality. The Intermountain Risk Score independently predicted short- and long-term mortality in STEMI patients with cardiogenic shock, outperforming the SYNTAX score II.
