Abstract: Objective: To apply the UK-BCIS CHIP Score system to identify patients who meet the criteria for complex percutaneous coronary intervention, thereby enabling the development of a personalized therapeutic strategy.Method: Retrospective cohort of patients with chronic coronary syndrome, unstable angina, and non-ST-segment elevation myocardial infarction who underwent percutaneous coronary intervention between January 2018 and March 2024 at a tertiary care hospital in Mexico.A univariate survival analysis was performed, represented by a Kaplan-Meier curve.A Cox regression model was used to estimate cardiovascular mortality with statistically significant angiographic variables.results: The median survival follow-up in patients with a score of 0 was 77 months (95% CI: 76-78); with a score of 1-2, 66 months (95% CI: 62-69); with a score of 3-4, 39 months (95% CI: 34-43); and with a score ≥ 5, 12 months (95% CI: 7-16).C-index: 0.86.The Cox regression model showed that a higher UK-BCIS CHIP Score (HR: 2.533; 95% CI: 2,013-3,186) was significantly associated with an increased risk of cardiovascular mortality and one-year hospital readmission.Conclusions: Appropriate stratification using the UK-BCIS CHIP Score was independently associated with an increased risk of one-year cardiovascular mortality and hospital readmission after percutaneous coronary intervention.
