Abstract:

Background and aims:
The association between inflammation and atherosclerosis has been well described in the literature. There is now mounting evidence in support of adipose tissue as a reservoir for inflammatory markers. Epicardial adipose tissue (EAT) has been shown to associate with coronary atherosclerosis and found to be a predictor of future adverse cardiovascular events. This study, VIA-EAT, assesses the change in epicardial fat volume (EFV) after treatment with an investigational anti-inflammatory agent (VIA-2291) in a cohort of post-acute coronary syndrome (ACS) patients.
Methods:
This study is derived from a post-hoc analysis of a previously conducted randomized clinical trial (NCT00358826). Patients were recruited for a prospective, double-blind, multi-center randomized trial of a 5-lipooxygenase inhibitor or placebo in a 3:1 randomization, including doses of placebo, and 25 mg, 50 mg and 100 mg of active treatment. Cardiac computed tomography was performed at baseline and at 24 weeks after treatment with VIA-2291. EAT and pericardial adipose tissue (PAT) were measured using previously published methodology. A Pearson correlation test was used to determine the relationship between change in epicardial fat and change in plaque composition.
Results:
We analyzed 54 pre- and post-treatment scans. There were no major differences between traditional cardiovascular risk factors among the 4 randomized study arms. There was a significant decrease in EAT and PAT in patients in the treatment arms vs. placebo, -3.0 ± 8.2mm3 and -3.9 ± 10.9mm3 vs. 1.7 ± 7.5mm3 and 1.4 ± 10.7mm3 (p = 0.001), respectively. The changes in EAT and PAT were more pronounced in patients taking 100 mg of the drug vs. placebo: 4.2 ± 9.6mm3, -7.6 ± 8.5mm3, p = 0.0001, respectively. In a subgroup analysis, reduction in epicardial fat volume correlated with reduction in total atherosclerotic plaque volume across all VIA treatment groups, r = 0.52 (p = 0.004).
Conclusions:
After adjustment for traditional cardiovascular risk factors including age, gender, body mass index, dyslipidemia and smoking, VIA-2291 decreases EAT and PAT in individuals with recent ACS. Treatment with the drug also appears to alter plaque volume and composition.
