Temporal trends in patient characteristics, presumed causes, and outcomes following cardiogenic shock between 2005 and 2017: a Danish registry-based cohort study.

Between 2005 and 2017, we observed significant temporal decreases in ACS, heart failure, and arrhythmias as presumed causes of first-time CS, whereas cardiac arrest significantly increased. Although overall 30-day and 1-year mortality were stable, significant decreases in mortality for ACS and arrhythmias as presumed causes of CS were seen.
