Key result
Coronary artery disease was associated with significantly lower serum adiponectin concentrations and reduced ADIPOQ gene expression in subcutaneous adipose tissue compared to patients without CAD.
Why the study?
The study aimed to determine the expression of the adiponectin gene and high-molecular-weight adiponectin content in epicardial and subcutaneous adipose tissue in patients with ischemic heart disease.
Does the expression of the adiponectin gene and high-molecular-weight adiponectin in epicardial and subcutaneous adipose tissue differ between patients with and without ischemic heart disease?

Does the expression of the adiponectin gene and high-molecular-weight adiponectin in epicardial and subcutaneous adipose tissue differ between patients with and without ischemic heart disease?
Absolute Event Rate: 22.1% vs 29.6%
p-value: p=<0.001
Decreased serum concentration of adiponectin and reduced expression of the ADIPOQ gene in subcutaneous adipose tissue are associated with ischemic heart disease.
Reduced ADIPOQ expression in SCAT associates with IHD; leaves open its role as local biomarker or target.
Aim To determine the expression of adiponectin gene (ADIPOQ) and the content of high-molecular-weight adiponectin (HMWA) in epicardial (EAT) and subcutaneous adipose tissue (SCAT) in patients with ischemic heart disease (IHD).Material and methods Paired samples of EAT and SCAT and blood serum were withdrawn from patients with IHD after bypass surgery and 16 subjects without IHD (comparison group). Matrix RNA (mRNA) level was measured using real-time polymerase chain reaction. HMWA levels in EAT and SCAT were evaluated by Western blotting. Serum adiponectin concentration was measured immunoenzymatically. For all patients, echocardiography was performed to measure the EAT thickness; coronarography was performed to determine severity of coronary atherosclerosis.Results Serum adiponectin concentration was lower in IHD patients than in the comparison group (p<0.001). Levels of ADIPOO gene mRNA and HMWA in SCAT were lower in IHD patients than in the comparison group (р=0.020 and p=0.003, respectively). The HMWA level in EAT was lower with the EAT thickness of 8 mm compared to the HMWA level in IHD patients with EAT ≤8 mm (p=0.034).Conclusion The decreased serum concentration of antiatherogenic adiponectin and the reduced expression of ADIPOQ gene in SCAT (mRNA, HMWA) are associated with IHD.

Побожева et al. (2020) conducted a cross-sectional in Coronary artery disease (n=90). Coronary artery disease vs. Patients without coronary artery disease was evaluated on Serum adiponectin concentration (ng/ml) (p=<0.001). Coronary artery disease was associated with significantly lower serum adiponectin concentrations and reduced ADIPOQ gene expression in subcutaneous adipose tissue compared to patients without CAD.
