Clinical and echocardiographic characteristics in patients with heart failure and type 2 diabetes.

Objective: The coexistence of type 2 diabetes (T2D) and heart failure (HF) has obvious consequences during cardiovascular diagnosis. This study evaluated the relationship between T2D and clinical and echocardiographic features of patients with HF. Methods & results: 121 patients with HF were clinically evaluated by echocardiography in this case-control study. They were divided into two groups based on the presence of T2D. Patients with diabetes were subdivided and compared via an HbA1c control. Significant differences between T2D and non-T2D groups were detected by comparing the left atrial diameter, E/E' and left ventricular end-diastolic diameter. When comparing patients with diabetes, differences in acute heart failure episodes, left ventricular ejection fraction, left atrial diameter and E/E' were evaluated. Conclusion: T2D was associated with important cardiac alterations and more severe HF. Poor control of diabetes resulted in worse cardiovascular outcomes.
