Publication Description
Background: Heart failure is a prominent complication of type 2 diabetes mellitus (T2D). The goal of this study was to provide longitudinal data on cardiac structure and function (and cross-sectional comparison to normal-weight and obese controls without T2D) in individuals followed from adolescence with youth-onset T2D. Methods: In the TODAY study (Treatment Options for Type 2 Diabetes Mellitus in Adolescents and Youth), echocardiograms were performed at study years 4 to 5 and 9 to 10. Echocardiograms were also obtained at years 8 to 9 in a control population of age, race/ethnicity, and sex-matched normal-weight and obese individuals without diabetes mellitus. Study outcomes were measures of left ventricular structure and function. The cohort included 411 participants with T2D, 194 obese controls, and 51 normal-weight controls. Results: At follow-up, mean participant age was 23 years, 65% women, 20% non-Hispanic white, 35% non-Hispanic black, and 39% Hispanic. Ejection fraction was https://www.clinicaltrials.gov ; Unique identifier: NCT00081328.
