To investigate the association between intrinsic capacity (IC) and hospital readmission in patients with coronary artery disease (CAD) undergoing percutaneous coronary intervention (PCI), highlighting the novelty of this research.
Key Findings:
Higher IC score (indicating poorer IC) was independently associated with increased all-cause rehospitalization risk (HR = 3.07, 95% CI 1.89–5.00).
Higher IC score was also linked to increased cardiovascular rehospitalization risk (HR = 5.23, 95% CI 2.30–11.89).
IC score was not a significant predictor of non-cardiovascular rehospitalization.
RCS curves indicated a linear positive relationship between IC score and HR of cardiac rehospitalization with a cutoff of 2.5.
ROC curve for all-cause rehospitalization showed IC score with an AUC of 0.692 (95% CI: 0.664–0.729).
Interpretation:
IC score serves as an accessible, independent, and robust predictor of cardiovascular rehospitalization after PCI in CAD patients, with implications for personalized care.
Limitations:
Retrospective design may introduce bias.
Single-center study limits generalizability and may affect the applicability of findings.
Potential confounding factors not fully controlled.
Conclusion:
Assessing intrinsic capacity can enhance personalized risk stratification and long-term care planning for CAD patients post-PCI, emphasizing its clinical relevance.
These 10 states make it more practical for physicians to participate in hospital ownership by aligning statutory structure, corporate practice of medicine rules, and population trends.
