Main finding · In-hospital mortalityResult — go to the resultAdjusted odds ratio 1.47 95% CI 1.43–1.52Authors' conclusion
With medical advances during the past 10 years, the mortality of CS has decreased significantly, but the mortality of HF-CS remains high.

Trends over the 10-year study period
- In-hospital mortality rate decreased and actual medical costs tended to increase, regardless of cardiogenic shock (CS) aetiology
