J-shaped relationship between creatinine levels and the risk of three major adverse events in patients after percutaneous coronary intervention

Background and aims: To evaluate the correlation between creatinine (Cre) level and the risk of three kinds of adverse events in patients after percutaneous coronary intervention (PCI), and to clarify its potential correlation threshold and independent predictive value. Methods and results: = 0.0301). Conclusion: There is a J-shaped correlation between Cre level and the risk of three kinds of adverse events in patients after PCI, and the inflection point of 110 μmol/L can be used as the key threshold for clinical risk stratification and individualized intervention.
