Comparison of the prognosis among in-hospital survivors of cardiogenic shock based on etiology: AMI and Non-AMI

Area of Science:

• Cardiology
• Clinical Research
• Public Health

Background:

• Limited data exists on long-term mortality and rehospitalization rates for cardiogenic shock (CS) survivors.
• Understanding these outcomes is crucial for both acute myocardial infarction (AMI)-CS and non-AMI-CS patient groups.

Purpose of the Study:

• To investigate and compare post-discharge mortality and rehospitalization risks in survivors of AMI-CS versus non-AMI-CS.
• To identify specific risk factors and temporal trends in adverse events following hospital discharge.

Main Methods:

• A retrospective cohort study utilizing the Taiwan National Health Insurance Research Database.
• In-hospital CS survivors were followed for three years, with mortality and rehospitalization analyzed using Kaplan-Meier curves and Cox regression models.

Main Results:

• Overall mortality and rehospitalization rates were high, with cardiovascular issues accounting for a significant portion.
• Non-AMI-CS patients had higher initial mortality burden but lower adjusted risks for all-cause and CV mortality within the first year compared to AMI-CS.
• After one year, the mortality risk reversed, with non-AMI-CS patients exhibiting higher risks, while AMI-CS patients consistently showed higher risks for CV rehospitalization.

Conclusions:

• In-hospital AMI-CS survivors face elevated risks of CV rehospitalization and 30-day mortality.
• Non-AMI-CS survivors are at greater risk of mortality beyond the one-year follow-up mark.
