    Introduction : The aim of the paper is the detection of changes in function of the left atrium (LA) and left ventricle (LV) in asymptomatic diabetic patients ( 1 ), distinguished by the control group, using two-dimensional (2D) speckle tracking echocardiography. Methods : 50 asymptomatic patients with diabetes mellitus were analyzed (28 males and 22 females) with an average age of 56,4 years (56±20 years). In control group without verified disease, 50 individuals have been chosen randomly, 26 males and 24 females, with an average age of 55.3 years (55.3±17). Results and Conclusions : 1 . Decrease of 2D strain of left ventricle is registered in patients with diabetes, starting from the global longitudinal strain (GLS) (-21.79 vs. 16.7%), myocardial longitudinal strain (LS) (17.69 vs 13.89%) and global radial strain of LV (GRS) (51 vs 42.9%) ( Figure 1 ). 2 . Minimal value from -17% is registered of LS values at control group and from -14.2% at diabetic group where registered 3 . Extension of T2P (time to peak) longitudinal and transversal strain values in patients with diabetes is registered. 4 . Increased value of LV mass at patients with diabetes is registered in our study (133 gr vs 123 gr), 5 . Insignificant increase of LA volume is registered in diabetic group (21,82 vs 20,66 ml/m 2 ). 6 . EF of LA is decreased in diabetic patient (55.69 vs 50.58%) together with decrease fractional area contraction (FAC) of LA (69.56 vs 41.23%) ( Figure 2 ). 7 . Decrease in values of end diastolic longitudinal strain (LS) of LA is registered in diabetic patients (48,78 vs 37.33%) 8 . LA strain rate (SR) of E wave is decreased in diabetic patient (1,84 vs 0,91), with smaller decrease of SR of A wave from (2.21 vs 1.97) 9 . E/A SR relation is decreased in the diabetic patients vs control group (0,83 vs 0,43) 10 . Decreased strain parameters of LV also decrease and LV compliance, which decrease the passive E wave SR and increase active A SR phase of LA function.
