Creatinine levels show J-shaped association with adverse events after PCI for myocardial infarction.

This was a retrospective cohort analysis of 3,878 patients diagnosed with acute myocardial infarction who received percutaneous coronary intervention (PCI). The study examined creatinine levels as an exposure, but the comparator was not reported. The primary outcome was three types of adverse events that occurred post-procedure.

The main result was a J-shaped relationship between creatinine levels and the likelihood of the three adverse events, with a nonlinear P value of < 0.001. There were 996 instances (25.7%) of adverse events reported. The effect size was not reported.

Safety and tolerability data were not reported, including adverse events, serious adverse events, and discontinuations. The follow-up duration was not reported.

Key limitations include the observational design, which cannot establish causation, and the lack of a comparator group. The study does not report specific creatinine thresholds or independent predictive values beyond the J-shaped relationship.

Practice relevance is not reported. The findings suggest an association between creatinine levels and post-PCI adverse events in this population, but clinical application requires caution due to the study's design and missing details.
