International audience. Aims Diastolic dysfunction is frequent in patients with type 2 diabetes mellitus (DM2) and associated with a poor prognosis. This study aimed to describe diastolic function changes over time in DM2 patients and to identify predictive factors of diastolic function deterioration. Methods and results Diastolic function was assessed by echocardiography according to the EACVI/ASE recommendations at baseline and 3-year follow-up in a prospective cohort of 310 DM2 patients without overt heart disease. Predictors of diastolic function deterioration were identified using logistic regression analysis. During the 3-year follow-up, prevalence of diastolic dysfunction increased from 49% to 67% (P = 0.001). Only 32% of the patients had a normal diastolic function both at baseline and 3 years and 27% of the patients presented diastolic function deterioration. At multivariable analysis, age (OR = 1.05 [1.01-1.09], P \textless 0.01), retinopathy (OR = 2.00 [1.10-3.63], P = 0.02), and increase in systolic blood pressure during follow-up (OR = 1.03 [1.01-1.04], P \textless 0.01) were predictive of diastolic function deterioration. Conclusion Age, retinopathy, and increase in blood pressure over time are associated with an increased risk of diastolic function deterioration in DM2 patients. The presence of these co-factors might help to early identify patients at risk of heart failure.
