Korean AMI Cohort Outcomes by LVEF Category, 2011-2020

Between November 2011 and June 2020, a cohort of 27,903 patients with acute myocardial infarction (AMI) from a Korean nationwide registry was analyzed. The study by Seok Oh evaluates 3-year all-cause mortality outcomes stratified by four left ventricular ejection fraction (LVEF) categories. The results indicate patients with supranormal LVEF experienced the lowest mortality.

Use Cases

• Analyze mortality risk based on LVEF categories mentioned in the description
• Validate clinical outcomes for AMI patients with supranormal LVEF
• Compare survival models across different LVEF groups
• Study temporal trends in AMI patient outcomes from a national registry

Strengths

• 27,903 patient records from a nationwide cohort
• Data spans a time range from November 2011 to June 2020
• Primary outcome is a 3-year all-cause mortality metric

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to the Korean cohort
