Clinical Scorecard: Link Between Localized Epicardial Adipose Tissue and Myocardial Ischemia Defined by CT-Derived Fractional Flow Reserve: A Retrospective Analysis of Coronary CTA in Patients with Hypertension and Type 2 Diabetes Mellitus

At a Glance

Key Highlights

• EAT thickness is greater in ischemic subgroups compared to controls.
• Left atrioventricular groove EAT (LAVG-EAT) is independently associated with myocardial ischemia.
• LAVG-EAT improves discrimination of ischemia beyond conventional clinical variables.
• Study included 576 participants with stratification by hypertension and T2DM.

Guideline-Based Recommendations

Diagnosis

• Myocardial ischemia defined as distal CT-FFR ≤ 0.80 in at least one major coronary artery.

Management

• Consider region-specific EAT metrics for risk stratification in patients with hypertension and/or T2DM.

Monitoring & Follow-up

• Regular assessment of EAT thickness may provide insights into myocardial ischemia risk.

Risks

• Increased EAT thickness is associated with higher risk of myocardial ischemia.

Patient & Prescribing Data

Adults aged ≥18 years with suspected coronary artery disease.

Patients with hypertension and T2DM may require tailored management strategies based on EAT metrics.

Clinical Best Practices

• Utilize CT-FFR for noninvasive assessment of hemodynamic significance in coronary lesions.
• Incorporate EAT thickness measurements in the evaluation of myocardial ischemia.
