Abstract
Abstract
Background:
Several studies have pointed out the existence of cardiac dysfunction in patients with type 1 diabetes mellitus (DM) even in the absence of ischemic, valvular, or hypertensive heart disease. The present study evaluated cardiac dysfunction and the relationship between severity of disease and degree of cardiac dysfunction in children with type 1 DM.
Methods:
In this prospective study, 31 patients with type 1 DM and 33 sex- and age-matched healthy children were evaluated with conventional echocardiography and tissue Doppler echocardiography (TDE). A correlation between cardiac functions and glycated hemoglobin (HbA
Results:
TDE results indicated that mitral valve early diastolic annular peak flow rate (E′), mitral valve systolic flow rate (S′), ratio of mitral valve early diastolic peak flow rate to mitral valve early diastolic annular peak flow rate (E/E′), and left ventricular (LV) myocardial performance index (MPI) were higher, and LV ejection time (ET) was shorter in patients with type 1 DM (p<0.05). In addition, tricuspid valve E′ and right ventricular (RV) MPI were higher, while RV ET and tricuspid E/E′ were lower in patients with type 1 DM compared to healthy children (p<0.05).
Conclusions:
Although conventional echocardiography revealed no difference between patients with type 1 DM and healthy children, TDE showed dysfunctions of both ventricles. This state is closely related to degree of blood glucose level control. These findings signify diagnostic value of TDE in the early detection of cardiac effects among patients with type 1 DM.
