[Epicardial adiposity as risk factor of coronary atherosclerosis]
Insights
Epicardial adiposity, measured as thickness of epicardial fat, is a significant predictor of coronary atherosclerosis. Higher epicardial fat thickness is associated with more severe coronary artery disease and increased risk.
Area of Science:
- Cardiology
- Medical Imaging
- Biomedical Engineering
Background:
- Coronary atherosclerosis is a leading cause of cardiovascular disease.
- Epicardial adipose tissue plays a role in cardiovascular health.
- Understanding predictors of coronary atherosclerosis is crucial for risk stratification.
Purpose of the Study:
- To investigate the association between epicardial adiposity and the risk and severity of coronary atherosclerosis.
- To determine if epicardial fat thickness is a predictor of significant coronary artery disease.
Main Methods:
- Study included 138 men with ischemic heart disease, angina, and obesity.
- Coronary angiography (CAG) was performed to assess coronary atherosclerosis.
- Transthoracic echocardiography (ECG) was used to measure epicardial fat thickness (tEF).
Main Results:
- Average tEF was highest in patients with multiple coronary artery stenoses.
- ROC analysis identified tEF as a predictor of significant coronary atherosclerosis (sensitivity 80.4%, specificity 67.6%, cut-off 6 mm).
- Epicardial adiposity was significantly associated with coronary atherosclerosis (OR 4.44), along with age, leptin, resistin, and waist circumference.
Conclusions:
- Epicardial fat thickness is a valuable predictor of significant coronary atherosclerosis.
- Increased epicardial adiposity is linked to a higher risk and severity of coronary artery disease.
- tEF measurement via echocardiography can aid in assessing cardiovascular risk.
Aim:
To study effect of epicardial adiposity on risk of development and severity of coronary atherosclerosis.
Material And Methods:
We registered classical metabolic risk factors (RF) and additional factors of cardiovascular risk in 138 men aged 55.47+/-9.07 years with ischemic heart disease (IHD), functional class (FC) II-III angina, and I-III degree obesity. Diagnostic coronary angiography (CAG) was performed in all patients. Thickness of epicardial fat (tEF) in millimeters was measured at transthoracic echocardiography (ECG).
Results:
Average tEF indexes were highest (10 [8; 10] mm) in the group of patients with multiple stenoses in coronary arteries (CA). According to ROC-analysis tEF appeared to be a predictor of significant coronary atherosclerosis. Its sensitivity was 80.4%, specificity - 67.6 % (cut-off value 6 mm). Epicardial adiposity was among factors associated with presence of coronary atherosclerosis (odds ratio [OR] 4.44, 95% confidence interval [CI] 2,06 to 9.59; p<0,001) along with age (OR 6.56; 95% CI 2.59 to 16.60; p=0,001), leptin (OR 3.50; 95% CI 1.46 to 8.37; p <0,001), resistin (OR 3.13; 95% CI 1.32 to 7.42; p <0,001) and waist circumference (OR 1.65; 95% CI 0.72 to 3.80; p=0.018).
