Glycemic variability is associated with diastolic dysfunction in patients with type 2 diabetes.

Aim: To investigate the relationship between glycemic variability (GV) and diastolic dysfunction in patients with type 2 diabetes mellitus (DM) without coronary artery disease.

Methods: Seventy-eight patients with type 2 DM without coronary artery disease were enrolled into the study. Diastolic function was assessed by echocardiography (Philips IE33); GV was evaluated by continuous monitoring of glucose (CGM, Guardian™ Connect System, Medtronic).
