Nurse-Assessed Intrinsic Capacity Scores for PCI Patients Predicting Rehospitalization

A retrospective cohort study of coronary artery disease patients following percutaneous coronary intervention. The dataset likely contains intrinsic capacity scores assessed within 48 hours of admission, linked to outcomes including all-cause and cardiovascular rehospitalization. It was authored by Yuning Zhao and last updated in April 2026.

Use Cases

• Predicting all-cause rehospitalization risk based on early intrinsic capacity scores.
• Modeling cardiovascular-specific rehospitalization risk using the reported hazard ratios.
• Evaluating the predictive performance of intrinsic capacity via ROC curve analysis as described.
• Conducting subgroup analyses across lesion morphologies and revascularization strategies.

Strengths

• Intrinsic capacity scores were assessed within a specific 48-hour window after admission.
• Analysis includes hazard ratios for outcomes, such as HR=3.07 for all-cause rehospitalization comparing IC=4 to IC=0.
• Predictive performance is quantified with an AUC of 0.692 for all-cause rehospitalization.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 19.7 KB, indicating limited scope.
