GHRL and type 2 diabetes mellitus: At the follow-up end, 50 patients experienced LV-DF normalisation, which was predicted by tissue miR-126 (HR 1.344, CI 95% 1.126-1.937), and ghrelin (HR 1.123, CI 95% 1.016-1.310).<h4>Conclusions</h4>In T2DM obese patients, abdominal fat excision could reduce inflammation, up-regulating serum ghrelin and inducing miRs implied in LV-DF normalisation at 1 year of follow-up.<h4>Clinical research trial number</h4>NCT05988346.
