Elevated circulating follistatin associates with increased risk of mortality and cardiometabolic disorders.

Previous study showed that elevated circulating hepatokine follistatin (FST) associates with an increased risk of type 2 diabetes by inducing adipose tissue insulin resistance. Here we explore further the relationships between plasma FST levels with mortality and health outcomes. The population-based Malmö Diet Cancer cardiovascular cohort (n = 4733, age 45-68 years) was used to study plasma FST in relation to incidence of health outcomes, by linkage with national patient registers. Cox regression analysis was used to assess the associations of plasma FST and outcomes, with adjustments for multiple potential confounding factors. During the mean follow-up time of 22.64 ± 5.84 years in 4,733 individuals, 526 had incident stroke, 432 had ischemic stroke, 530 had incident coronary events (CE), 339 had incident heart failure (HF), 320 had incident chronic kidney disease (CKD) and 1,843 individuals died. Hazard ratio (HR) per standard deviation increase in FST levels adjusted for multiple risk factors was 1.05 (95%CI: 1.00-1.11, p = 0.036) for mortality; 1.10 (95%CI: 1.00-1.20, p = 0.042) for stroke; 1.13 (95%CI: 1.03-1.25, p = 0.014) for ischemic stroke; 1.16 (95%CI: 1.03-1.30, p = 0.015) for HF; and 1.38 (95%CI: 1.12-1.70, p = 0.003) for a diagnosis of CKD. In MDC-CC individuals without prevalent or incident diabetes, the association between FST and stroke, CE and CKD remained significant; but not with mortality or HF. Elevated circulating FST associates with an increased risk of mortality and HF, which partly may be mediated by diabetes. FST also associated with stroke, ischemic stroke, CE and CKD, independently of established risk factors including diabetes. Copyright © 2023 The Authors. Published by Elsevier B.V.
