Clinical Scorecard: Relationship Between the C-Reactive Protein-Triglyceride Glucose Index and Microvascular Obstruction Alongside Long-Term Outcomes in Acute Myocardial Infarction Patients: Insights from a CMR Study

At a Glance

Key Highlights

• CTI levels are independently associated with increased risk of microvascular obstruction (MVO) after PCI.
• Higher CTI levels correlate with long-term major adverse cardiovascular events (MACE) risk, especially in non-diabetic patients.
• CTI integrates inflammatory burden and insulin resistance into a single composite indicator.

Guideline-Based Recommendations

Diagnosis

• Use cardiac magnetic resonance (CMR) for diagnosing microvascular obstruction in AMI.

Management

• Consider CTI as a tool for early risk stratification and individualized microvascular protection strategies after PCI.

Monitoring & Follow-up

• Monitor CTI levels for assessing long-term outcomes in AMI patients.

Risks

• Increased risk of MVO and long-term MACE associated with higher CTI levels.

Patient & Prescribing Data

967 AMI patients, including 255 with diabetes mellitus and 712 without diabetes.

Successful primary PCI performed within 12 hours of symptom onset.

Clinical Best Practices

• Utilize CTI for risk stratification in AMI patients post-PCI.
• Incorporate CMR imaging for accurate assessment of MVO.
