SIRT1 and type 2 diabetes mellitus: We investigated ghrelin expression in T2DM obese patients after abdominal fat excision, and in those with LV-DF normalisation at 1 year of follow-up.<h4>Materials and methods</h4>Two-hundred and two T2DM obese patients enroled for abdominoplastic surgery were divided into those with normal LV-DF (group 1: E/E' < 9, n 76) and those with altered LV-DF: group 2 (9 < E/E' < 14; n 96) and group 3 (E/E' > 14, n 28).<h4>Results</h4>Patients with LV-diastolic dysfunction had over-inflammation, lower SIRT1 and higher abdominal fat sodium-glucose-transporter-two (SGLT2) expression (p < 0.05).
