Case Fatality Rate of Patients with Acute Myocardial Infarction in 253 Chest Pain Centers - China, 2019-2020

Area of Science:

• Cardiology
• Public Health
• Epidemiology

Background:

• Acute myocardial infarction (AMI) is a critical cardiovascular disease.
• Case fatality rate (CFR) is a key indicator of AMI prognosis.

Purpose of the Study:

• To analyze the case fatality rates (CFR) of Acute Myocardial Infarction (AMI).
• To identify factors influencing AMI outcomes, including hospital grade and care setting.

Main Methods:

• Retrospective analysis of AMI patient data.
• Calculation of 30-day, 60-day, and 90-day CFR.
• Comparison of CFR across different hospital grades and care settings (in-hospital vs. out-of-hospital).

Main Results:

• Overall 30-day, 60-day, and 90-day CFR for AMI were 5.9%, 6.9%, and 7.6%, respectively.
• Lower CFRs were recorded in Grade III hospitals compared to Grade II hospitals.
• In-hospital CFR was significantly lower than post-discharge out-of-hospital CFR.

Conclusions:

• Findings provide evidence for targeted prevention strategies for AMI.
• There is a need to enhance treatment levels for AMI patients in Grade II hospitals.
• Optimizing care settings can potentially reduce AMI mortality.
