P190 CAROTID DOPPLER ULTRASONOGRAPHIC AND DAPAGLIFOZIN IN TYPE 2 DIABETIC PATIENTS

Abstract

Abstract Background Carotid Doppler ultrasonography (USG) is widely used to measure haemodynamic parameters, such as Intima–Media Thickness (IMT) and blood flow velocities (i.e. Peak–Systolic Velocity [PSV], End–Diastolic Velocity [EDV], and Resistive Index [RI]). Dapaglifozin (SGLT2i) have been shown to reduce the risk of cardiovascular disease in type 2 diabetes (T2DM) patients. SGLT2i is a sodium–glucose co–transporter 2 inhibitor that reduces renal glucose reabsorption, thus increasing urinary glucose excretion. This leads to sustained systolic and diastolic blood pressure reduction, through natriuresis. We hypothesized that this agent would also reduce arterial stiffness. Aim The purpose of this study was to evaluate cardiovascular disease risk indirectly through USG of carotid artery vascular markers in T2DM patients using dapagliflozin. Methods and Results 40 patients presenting to our clinic between march 2019 and march 2021 and diagnosed with T2DM were included in the study. These were divided into two groups : 1) a dapagliflozin group of 20 patients and 2) 20 patients non–dapagliflozin control group. Velocity parameters were: peak–systolic velocity (PSV), end–diastolic velocity (EDV), pulsatility index (PI), resistive index (RI). Examination was performed on distal portion of CCA, and we took the mean of both CCA. The mean duration of follow–up was 2.0 years. Mean ages were 55 ± 10 years in the dapagliflozin group and 50 ± 10 in the control group. Common carotid artery, PSV, and EDV parameters were higher while RI was lower (p ˂ 0.01), in the dapagliflozin group than in the control group. Vascular resistance was lower in the group using dapagliflozin for diabetes management. In addition In the dapagliflozin group, the IMT decreased after dapagliflozin therapy (P < 0.01). Conclusions haemodynamic parameters were better performing in the group using dapagliflozin for diabetes management. Finally SGLT2i can decrease the IMT in patients with T2DM, which is closely related to cardiovascular benefit in patients with T2DM.
