Materials and Methods Between October 2008 and December 2022, cardiac MRI and echocardiography were performed in prospectively recruited cohorts with type 2 diabetes mellitus, heart failure with preserved ejection fraction, and severe aortic stenosis, as well as asymptomatic participants without diabetes. Diastolic dysfunction was classified using established echocardiography guidelines. Global circumferential and longitudinal PEDSR and PLDSR were measured at cardiac MRI. Linear regression was performed to identify independent associations between LV diastolic strain rates and remodeling. Results A total of 600 participants (mean age, 65.2 years ± 8.4 [SD]; 361 of 600 male participants [60%]) were included. Proportions of participants with normal diastolic function and those with grade 1, indeterminate, and grade 2 or 3 diastolic dysfunction were 92 of 600 (15%), 401 of 600 (67%), 85 of 600 (14%), and 22 of 600 (4%), respectively.
