Epicardial Fat Volume as a Good Predictor for Multivessel Coronary Artery Disease

Area of Science:

• Cardiology
• Medical Imaging
• Biomedical Engineering

Background:

• Epicardial adipose tissue (EAT) plays a role in coronary artery disease (CAD) pathogenesis.
• Quantifying epicardial fat volume (EFV) may offer insights into CAD.
• Understanding the relationship between EFV and CAD severity is crucial.

Purpose of the Study:

• To investigate the association between epicardial fat volume (EFV) and the presence of obstructive and multivessel CAD.
• To determine if EFV is an independent predictor of obstructive CAD.
• To evaluate EFV's predictive value for multivessel disease.

Main Methods:

• Observational study of 87 adult subjects with suspected CAD.
• Epicardial fat volume (EFV) quantified by multidetector computerized tomography (MDCT).
• Coronary artery stenosis assessed by Invasive Coronary Angiography (ICA).

Main Results:

• Patients with obstructive CAD had significantly higher EFV (57 ± 20.14 cm³ vs. 44 ± 7.4 cm³; P < 0.001).
• EFV was significantly increased in multivessel disease cases (74 ± 24.3 ml vs. 53 ± 16.2 ml; P < 0.003).
• Multivariate analysis identified EFV as an independent risk factor for obstructive CAD (OR, 1.062; P < 0.005).

Conclusions:

• Elevated epicardial fat volume (EFV) is significantly associated with obstructive CAD.
• EFV is an independent predictor of obstructive CAD, irrespective of traditional risk factors and coronary calcium score.
• EFV serves as a valuable predictor for the occurrence of multivessel disease.
