Background Arterial stiffness is associated with increased risk for cardiovascular disease. The purpose of this study is to investigate the arterial stiffness and myocardial deformation in patients with poorly controlled diabetes mellitus type 2 before and after glycemic control by optimal medication. Methods In 50 patients with uncontrolled type 2 diabetes(age:52±10years)and 25 controls of similar age and sex and no atherosclerotic risk factors we measured at baseline and 6 months after glycemic control a) carotid-femoral pulse wave velocity(PWVc m/sec-Complior SP ALAM),central systolic blood pressure(cSBP -mmHg),augmentation index(AI%), of the aortic pulse wave(ArteriographTensioMed) b)S',E'(m/sec)andE'/A'of mitral annulus by Tissue Doppler c)LV longitudinal strain(GLS-%),systolic(LongSr-l/sec)and diastolic(LongSrE-l/sec)strain rate, twisting(Tw-deg),peak twisting(Tw)and untwisting(unTw-deg/sec)velocity using speckle tracking echocardiography.The degree of LV untwisting was calculated as the percentage difference between peak twisting and untwisting at MVO(%dp PeakTw-UntwMVO)and between peak twisting and untwisting at peak and end of the mitral inflow E wave d)perfusion boundary region(PBR- micrometers)of the sublingual arterial microvessels(ranged from 5-25 micrometers)using Sideview,Darkfield imaging(Microscan,Glycocheck).Increased PBR is considered an accurate index of reduced endothelial glucocalyx thickness because of a deeper RBC penetration in the glucocalyx e) Flow mediated dilatation(FMD) of the brachial artery and percentage difference of FMD (FMD%). Results Compared to controls,diabetics had higher PWVa(10.3±2.2 vs. 8.1±1.9), AI(27.9±15 vs. 19.4±14.7), PWVc(11.8±3.2 vs. 8.8±1.3),cSBP(136±20 vs. 119±18),PBR (2.1±0.2 vs 1.89±0.1)and lower GLS(-15±3 vs. -18±3),LongSr(-0.78±0.1 vs. -0.96±0.2),LongSrE(0.77±0.29 vs. 1.2±0.3),S',E' and E/A(p
