Clinical Scorecard: Link Between C-Reactive Protein-Triglyceride-Glucose Index and Coronary Microvascular Dysfunction Prognosis in Chronic Coronary Syndrome Patients

At a Glance

CategoryDetail
ConditionCoronary Microvascular Dysfunction in Chronic Coronary Syndrome
Key MechanismsInsulin resistance and inflammation as contributors to CMD and cardiovascular risk.
Target PopulationPatients with chronic coronary syndrome undergoing coronary angiography.
Care SettingSingle-center retrospective cohort study.

Key Highlights

  • CTI is independently associated with CMD and MACE in CCS patients.
  • Higher CTI predicts increased MACE risk, especially in CMD patients.
  • CTI demonstrates superior predictive accuracy for CMD-related MACE compared to TyG.

Guideline-Based Recommendations

Diagnosis

  • CMD defined by caIMR ≥ 25 U.

Management

  • Use CTI for early risk stratification and personalized management in CMD.

Monitoring & Follow-up

  • Follow-up for MACE risk assessment over a median of 35 months.

Risks

  • Increased risk of MACE associated with higher CTI levels.

Patient & Prescribing Data

Adults over 18 years with suspected or confirmed chronic coronary syndrome.

CTI integrates TyG and CRP for a comprehensive cardiovascular risk assessment.

Clinical Best Practices

  • Assess CMD using coronary angiography-derived index of microcirculatory resistance (caIMR).
  • Consider CTI as a biomarker for CMD and MACE risk in clinical practice.
