Sodium-glucose cotransporter-2 (SGLT-2) inhibitors represent a cutting-edge class of oral antidiabetic therapeutics that operate through selective inhibition glucose reabsorption in proximal renal tubules, consequently augmenting urinary excretion and attenuating blood levels. Extensive clinical investigations have demonstrated their profound cardiovascular efficacy. Parallel basic science research has elucidated the mechanistic pathways which diverse SGLT-2 beneficially modulate pulmonary vascular cells arterial remodeling. Specifically, these exhibit promising potential enhancing endothelial cell function, suppressing smooth muscle proliferation migration, reversing remodeling, maintaining hemodynamic equilibrium. This comprehensive review synthesizes current literature to delineate mechanisms by enhance function reverse thereby offering novel therapeutic perspectives for diseases.

Abstract Background Sodium–Glucose Cotransporter-2 Inhibitor (SGLT2i) is a novel oral drug for treating type 2 diabetes mellitus (T2DM) with demonstrated cardiovascular benefits. Previous studies in apolipoprotein E knockout mice have shown that SGLT2i associated attenuated progression of atherosclerosis. However, whether this effect extends to T2DM patients coronary atherosclerosis real-world settings remains unknown. Methods In longitudinal cohort study using computed tomography angiography (CCTA), who underwent ≥ CCTA examinations at our center between 2019 and 2022 were screened. Eligible had multiple plaques, defined as non-obstructive stenosis baseline not intervened during serial CCTAs. Exclusion criteria included time interval < 12 months, prior treatment, or initiation/discontinuation Plaque volume (PV) percent atheroma (PAV) measured each plaque analysis software. Patients plaques categorized based on therapy compared 1:1 propensity score matching (PSM) analysis. Results The 236 (mean age 60.5 ± 9.5 years; 69.1% male) 435 (diameter 50%, 31.7%). Following treatment median duration 14.6 (interquartile range: 13.0, 20.0) overall, non-calcified, low-attenuation PV PAV significantly decreased, while calcified increased (all p 0.001). Meanwhile, reductions overall PV, non-calcified PAV, greater SGLT2i-treated non-SGLT2i-treated PSM showed was higher (− 11.77 mm 3 vs. 4.33 , = 0.005), 16.96 − 1.81 0.017), 2.83% 3.36%, 0.001), 4.60% 0.70%, 0.003).
