J-Shaped Relationship Between Creatinine and Post-PCI Adverse Events in 3,878 Patients

A retrospective cohort analysis of 3,878 acute myocardial infarction patients who received percutaneous coronary intervention (PCI) between January 2018 and December 2020. The dataset, authored by Xiang Zhu and shared under a CC-BY-4.0 license, investigates the correlation between creatinine levels and three major adverse events post-PCI, identifying a key inflection point at 110 μmol/L.

Use Cases

• Modeling non-linear (J-shaped) risk relationships based on creatinine levels mentioned in the description
• Identifying clinical risk stratification thresholds for post-PCI patient management
• Validating predictive models for major adverse cardiovascular events (MACE, NACE, MACCE)

Strengths

• Includes data from 3,878 patient records, providing a substantial cohort size
• Analysis identifies a specific inflection point (110 μmol/L) for risk stratification
• Reports 996 instances (25.7%) of adverse events, offering a clear outcome measure

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count for the underlying data table is unknown, which may limit suitability assessment
• The 18.1 KB file size suggests a very limited scope, likely containing summary results rather than raw patient data
