Impact of off-hours admissions in STEMI-related cardiogenic shock managed with microaxial flow pump – insights from J-PVAD

ST-segment elevation myocardial infarction (STEMI) complicated by cardiogenic shock (STEMI-CS) is associated with high mortality rates. Patients admitted during off-hours, specifically on weekends and at night, show higher mortality rates, which is called the "off-hours effect". The off-hours effect in patients with STEMI-CS treated with mechanical circulatory support, especially Impella, has not been fully evaluated.
