Korean AMI Cohort Outcomes by LVEF Category, 2011-2020

Seok Oh published a dataset on figshare in April 2026 analyzing outcomes for acute myocardial infarction (AMI) patients with supranormal left ventricular ejection fraction (LVEF). The dataset includes 27,903 patients from a nationwide Korean cohort between November 2011 and June 2020, classified into four LVEF groups. It evaluates 3-year all-cause mortality as the primary outcome.

Use Cases

• Analyze mortality risk based on LVEF categories (supranormal, normal, mid-range, reduced)
• Validate Cox regression models for clinical outcomes using hazard ratios
• Study temporal trends in AMI patient outcomes over a 9-year period
• Benchmark clinical outcomes for supranormal LVEF against other LVEF groups

Strengths

• 27,903 patient records from a nationwide cohort
• Data spans a 9-year period from November 2011 to June 2020
• Primary outcome is clearly defined as 3-year all-cause mortality

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
