Abstract
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 < 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 < 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. Published on behalf of the European Society of Cardiology. All rights reserved.
