Acute cardiac care & resuscitation
Cardiogenic Shock With Acute Myocardial Infarction Among Older Adults in the United States
Authors' conclusion
From 2003 to 2021, for older patients with CS and AMI, hospitalizations increased, and mortality decreased.
Study context
- Population
- Hospitalizations of older patients ≥80 years with cardiogenic shock (CS) and acute myocardial infarction (AMI) from 2003 to 2021, compared with a reference relatively younger patient population (18–79 years)hospitalizations · older patients ≥80 years 207,333 · patients 18 to 79 years 675,491
- Participants
- 207,333 vs 675,491
- Exposure
- Older patients with a reference relatively younger patient population
- Older patients ≥80 yearsn = 207,333
- Patients 18 to 79 yearsn = 675,491
- Outcome
- Number of hospitalizations of older patients with AMI and CS
- Follow-up
- 2003-2006 vs 2016-2019
