Clinical Trial Summary

EARLY-MYO-OBESITY-CMR is a prospective, three-center, cardiac imaging study to investigate cardiac morphology, function, and tissue phenotypes in a cohort of non-diabetic obese adults, and compare with metabolically healthy non-obese controls.

Description:

1. Transthoracic echocardiography was performed to analyze the LV morphology and function. 2. CMR was performed within 24 hours of the echocardiographic examination to assess the cardiac morphology , cardiac function, and myocardial tissue characteristics. Standard cine images were acquired to quantify LV function and volume. T1 mapping-derived ECV values were used to detect subtle diffuse fibrosis , and late gadolinium-enhanced (LGE) imaging was used to identify focal fibrosis. Native T2 values were obtained to quantify myocardial edema . Global longitudinal peak systolic strain (GLS) and e' SR were assessed by tissue tracking analysis to detect subclinical systolic and diastolic dysfunction.
