Abstract
Interleukin-6 (IL-6) has been found to be a predictor of heart attack. We aimed to investigate the relationship of risk factor IL-6 with extent and severity of the coronary artery disease (CAD) evaluated using coronary computed tomography angiography (CCTA). A total of 303 participants without history of CAD undergoing CCTA were enrolled. Using the model of risk-adjusted Cox proportional-hazards, the association of IL-6 level with major adverse cardiac events (MACE) was detected. The participants were assigned into three study groups based on serum IL-6 level. Compared with those in the lowest tertile, patients with highest IL-6 level displayed higher atherosclerotic burden such as plaque extent defined as prevalence of obstructive CAD and segments with any plaque. After a median 3.0 year follow-up period, we also found that patients with highest IL-6 level experienced higher MACE risk and all-cause death compared with those from the lowest tertile. Among participants without CAD history who underwent CCTA, patients with high level of IL-6 had increased burden of atherosclerosis and higher MACE risk compared to participants of low level of IL-6.
