IL1B and coronary artery disorder: Garcia-Rubira et al. showed that individuals with a metabolic age (assessed using BIA) higher than their actual age had higher levels of body fat and higher levels of the pro-inflammatory Interleukin 1b (Il-1b), and those parameters were positively correlated with the FRS scale (Framingham Risk Score, including factors associated with a distant 10-year increased risk of developing coronary heart disease) [31].
