Residual CatLet Scores for Chronic Coronary Syndrome Prognosis

262 patients with chronic coronary syndrome after percutaneous coronary intervention (PCI) were analyzed for long-term outcomes. The dataset contains residual CatLet score (rCS) and CatLet revascularization index (CRI) metrics, used to predict major adverse cardiac events (MACEs) and recurrent angina. This real-world cohort was established from a single hospital between May 2019 and July 2020.

Use Cases

• Predict major adverse cardiac events (MACEs) using the residual CatLet score (rCS) and CatLet revascularization index (CRI) from patient records.
• Analyze the correlation between rCS/CRI tertiles and the incidence of recurrent angina in post-PCI patients.
• Compare the discriminative ability of rCS versus CRI for long-term MACEs using area under the curve (AUC) metrics derived from the study.
• Model hazard ratios for MACEs and recurrent angina based on multivariable Cox regression results for rCS and CRI.

Strengths

• Data from 262 patients provides a foundation for statistical analysis of post-PCI outcomes.
• Includes two validated angiographic scoring metrics (rCS and CRI) with reported hazard ratios and AUC values for predictive performance.
• Long-term follow-up data for major adverse cardiac events (MACEs) and recurrent angina over approximately 6.2 years.

Limitations

• Small sample size of 262 patients limits the generalizability of findings and statistical power for subgroup analyses.
• Single-center study from one hospital in China introduces potential geographic and institutional bias.
• Dataset scope is narrow, focused only on two specific scores (rCS, CRI) and their relationship to a limited set of cardiac outcomes.
