- Individuals with type 2 diabetes have a three-to-five-fold increased risk of developing heart failure. Diabetic cardiomyopathy is typified by left ventricular (LV) concentric remodelling, which is a recognised predictor of adverse cardiovascular events. Although the mechanisms underlying LV remodelling in type 2 diabetes are unclear, progressive aortic stiffening may be a key determinant. The aim of this study was to assess the relationship between aortic stiffness and LV geometry in younger adults with type 2 diabetes, using multiparametric cardiovascular magnetic resonance imaging. We prospectively recruited 80 adults (aged 18-65 years) with type 2 diabetes and no cardiovascular disease and 20 age- and sex-matched healthy controls. All subjects underwent comprehensive bio-anthropometric assessment and cardiac magnetic resonance imaging, including measurement of aortic stiffness by aortic distensibility (AD). Type 2 diabetes was associated with increased LV mass, concentric LV remodelling and lower AD compared with controls. On multivariable linear regression, AD was independently associated with concentric LV remodelling in type 2 diabetes. Aortic stiffness may therefore be a potential therapeutic target to prevent the development of heart failure in type 2 diabetes.
