Link Between Inflammatory Burden Index and One-Year MACE in HFpEF Patients

Overview

This study investigates the association between the Inflammatory Burden Index (IBI) and one-year major adverse cardiovascular events (MACE) in patients with heart failure with preserved ejection fraction (HFpEF) following myocardial infarction (MI). Higher logIBI was found to be independently associated with increased MACE risk, suggesting its potential utility in clinical risk stratification.

Background

Heart failure with preserved ejection fraction (HFpEF) is prevalent among patients with coronary artery disease, particularly those with a history of myocardial infarction (MI). Inflammation plays a critical role in adverse cardiovascular outcomes post-MI, yet its prognostic value in HFpEF remains unclear. Understanding the inflammatory burden can help identify high-risk patients and improve management strategies.

Data Highlights

MeasureValue
Patients with MACE74 (12.5%)
HR for logIBI and MACE1.828 (95% CI 1.529–2.186, P < 0.001)
HR for high IBI and MACE4.126 (95% CI 2.512–6.776, P < 0.001)
365-day AUC improvement0.790 to 0.832
C-index improvement0.776 to 0.817
Brier score0.075
Calibration slope0.938

Key Findings

  • Higher logIBI is independently associated with 1-year MACE in HFpEF patients post-MI.
  • LogIBI improves risk discrimination when added to a base clinical model.
  • The Youden-derived IBI cutoff of 7.70 was used for descriptive grouping and sensitivity analysis.
  • Decision curve analysis indicated a higher net benefit after incorporating logIBI.
  • Inflammation plays a significant role in adverse remodeling and recurrent cardiovascular events after MI.

Clinical Implications

The Inflammatory Burden Index (IBI) may serve as a practical tool for assessing residual inflammatory burden in HFpEF patients following MI. Clinicians should consider incorporating IBI into risk stratification strategies to identify patients at higher risk for adverse cardiovascular events.

Conclusion

The study highlights the prognostic value of the Inflammatory Burden Index in predicting one-year MACE in HFpEF patients after MI. Further validation is necessary before routine clinical application.
