AMI Patient Outcomes by LVEF Category, Korean Cohort 2011-2020

27,903 patients with acute myocardial infarction from a Korean nationwide cohort between November 2011 and June 2020. The data likely contains patient classifications by left ventricular ejection fraction and associated 3-year all-cause mortality outcomes. The study was authored by Seok Oh and shared on figshare.

Use Cases

• Analyze mortality risk based on left ventricular ejection fraction categories
• Compare clinical outcomes for patients with supranormal versus reduced ejection fraction
• Validate Cox model hazard ratios for mortality prediction
• Study the association between ejection fraction and long-term survival in AMI patients

Strengths

• 27,903 patient records from a nationwide cohort
• Data spans from November 2011 to June 2020
• Includes hazard ratios and confidence intervals for mortality outcomes

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
