Background: Recent trials have shown improved cardiovascular benefit associated outcomes with sodium glucose cotransporter-2 inhibitors (SGLT2i) and glucagon-like peptide-1 receptor agonists (GLP-1RA) treatment in patients (pts) with type 2 diabetes (T2D) and high cardiovascular (CV) risk. We examined the extent to which this new evidence has been applied in routine clinical care and whether race influenced differences in prescription rates between patients. Methods and results: We used data from the US Department of Veterans Affairs’ Clinical Assessment, Reporting, and Tracking (CART) Program (2015-2017 inclusive). Pts were deemed SGLT2i- or GLP-1RA-eligible based on EMPA-REG OUTCOME and LEADER trial criteria. Rates of use were examined among eligible pts by race/ethnicity in unadjusted and multivariable logistic regression models adjusted for age, insurance type, service connection, and clinical site. From 84 sites, 21,053 patients were eligible for an SGLT2i and 1,520 (7.2%) had one prescribed. Recipients of SGLT2i were younger (65.59 years vs 68.29 years) had a higher mean HbA1c (8.27% vs 8.02%) and were more likely white (86.0 % vs 82.6%). Compared to black pts, whites had higher odds of receiving the medication, OR = 1.38; 95% CI 1.05,1.85; p < 0.01. Among 11,913 Veterans eligible for an GLP-1RA, 477 (4.0%) had one prescribed. Recipients were younger (65.84 years vs 68.96 years), had a higher mean HbA1c (8.55% vs 8.09%) and were more likely white (83.6% vs 81.8%). Compared to black pts, whites had higher odds of receiving the medication, OR = 1.43; 95% CI 1.09, 1.92; p = 0.013. Representation of other racial/ethnic groups was insufficient for comparison. Conclusion: Appropriate prescription of SGLT2i or GLP-1RA was less likely among black than white US Veterans at high CV risk. Our results suggest that while overall uptake of these medications has been slow, there are substantial racial differences that exist concerning the prescribing of these medications. In view of these findings, additional research is needed to further investigate both institutional and clinical factors which may adversely affect the prescribing of SGLT2i and GLP-1RA in African American Veterans.

Abstract Funding Acknowledgements Type of funding sources: None. Background/Introduction: Type-2 diabetes mellitus (T2DM) exacerbates mechanisms of atherosclerosis and heart failure. Purpose We investigated the effect of novel antidiabetic drugs, glucagon like peptide-1 receptor agonists (GLP-1RA) and sodium-glucose cotransporter-2 inhibitors (SGLT-2i) and their combination on myocardial function. Methods A hundred-sixty T2DM patients (age: 58 ± 10years) were randomized to insulin (n = 40), liraglutide (n = 40), empagliflozin (n = 40) or their combination (GLP-1RA + SGLT-2i) (n = 40) as add-on to metformin. We measured at baseline and 1 year post-treatment: a) global LV longitudinal strain (GLS), systolic (GLSR) and diastolic (GLSR E) strain rate, global circumferential (GCS) and radial (GRS) strain, peak twisting (pTw), peak twisting velocity (pTwVel) and peak untwisting velocity (pUtwVel), b) global myocardial work index (GWI), global constructive (GCW) and global wasted work (GWW) derived by pressure-myocardial strain loops using speckle tracking imaging. Results After 1 year of treatment, all patients improved GLS, GCS, GRS and pUtwVel (p &lt; 0.05). GLP-1RA or GLP-1RA + SGLT-2i provided a greater increase of GLS (11.5% and 13% vs. 6.8% and 2.3%), GWI (12.7% and 17.4% vs. 3.1% and 2%), GCW (12.3% and 15% vs. 2.2% and 7.8%) and a greater reduction of GWW (38.7% and 41.6% vs. 13.5% and 4.9%) compared with insulin or SGLT-2i, despite a similar HbA1c reduction (p &lt; 0.05 for all comparisons) (Table). Patients under combined treatment with GLP-1RA + SGLT-2i achieved a 2-fold reduction of pTw and a 2-fold increase of pUtwVel than those under each one regimen or insulin (p &lt; 0.05). The dual therapy showed the greatest effect on measured myocardial markers in LVEF &lt; 55% (p &lt; 0.05). Conclusions One year treatment with GLP-1RA or combination of GLP-1RA and SGLT-2i resulted in a greater improvement of myocardial deformation and effective cardiac work than insulin or SGLT-2i treatment, independently of glycemic control in T2DM.

Abstract Objective To evaluate sodium-glucose cotransporter-2 (SGLT-2) inhibitors and glucagon-like peptide-1 (GLP-1) receptor agonists in patients with type 2 diabetes at varying cardiovascular and renal risk. Design Network meta-analysis. Data sources Medline, Embase, and Cochrane CENTRAL up to 11 August 2020. Eligibility criteria for selecting studies Randomised controlled trials comparing SGLT-2 inhibitors or GLP-1 receptor agonists with placebo, standard care, or other glucose lowering treatment in adults with type 2 diabetes with follow up of 24 weeks or longer. Studies were screened independently by two reviewers for eligibility, extracted data, and assessed risk of bias. Main outcome measures Frequentist random effects network meta-analysis was carried out and GRADE (grading of recommendations assessment, development, and evaluation) used to assess evidence certainty. Results included estimated absolute effects of treatment per 1000 patients treated for five years for patients at very low risk (no cardiovascular risk factors), low risk (three or more cardiovascular risk factors), moderate risk (cardiovascular disease), high risk (chronic kidney disease), and very high risk (cardiovascular disease and kidney disease). A guideline panel provided oversight of the systematic review. Results 764 trials including 421 346 patients proved eligible. All results refer to the addition of SGLT-2 inhibitors and GLP-1 receptor agonists to existing diabetes treatment. Both classes of drugs lowered all cause mortality, cardiovascular mortality, non-fatal myocardial infarction, and kidney failure (high certainty evidence). Notable differences were found between the two agents: SGLT-2 inhibitors reduced mortality and admission to hospital for heart failure more than GLP-1 receptor agonists, and GLP-1 receptor agonists reduced non-fatal stroke more than SGLT-2 inhibitors (which appeared to have no effect). SGLT-2 inhibitors caused genital infection (high certainty), whereas GLP-1 receptor agonists might cause severe gastrointestinal events (low certainty). Low certainty evidence suggested that SGLT-2 inhibitors and GLP-1 receptor agonists might lower body weight. Little or no evidence was found for the effect of SGLT-2 inhibitors or GLP-1 receptor agonists on limb amputation, blindness, eye disease, neuropathic pain, or health related quality of life. The absolute benefits of these drugs vary substantially across patients from low to very high risk of cardiovascular and renal outcomes (eg, SGLT-2 inhibitors resulted in 5 to 48 fewer deaths in 1000 patients over five years; see interactive decision support tool ( https://magicevidence.org/match-it/200820dist/#!/ ) for all outcomes. Conclusions In patients with type 2 diabetes, SGLT-2 inhibitors and GLP-1 receptor agonists reduced cardiovascular and renal outcomes, with notable differences in benefits and harms. Absolute benefits are determined by individual risk profiles of patients, with clear implications for clinical practice, as reflected in the BMJ Rapid Recommendations directly informed by this systematic review. Systematic review registration PROSPERO CRD42019153180.

Abstract Background/Introduction Type-2 diabetes mellitus (T2DM) is associated with endothelial and myocardial dysfunction. Purpose We investigated the effects of insulin, glucagon like peptide-1 receptor agonists (GLP-1RA), sodium-glucose cotransporter-2 inhibitors (SGLT-2i) and their combination on vascular and cardiac function of T2DM patients. Methods A hundred-sixty T2DM patients were randomized to insulin (n=40), liraglutide (n=40), empagliflozin (n=40) or their combination (GLP-1RA+SGLT-2i) (n=40) as add-on to metformin. We measured at baseline, 4 and 12 months post-treatment: a) perfused boundary region (PBR) of the sublingual arterial microvessels (marker of glycocalyx thickness), b) pulse wave velocity (PWV), central systolic blood pressure (cSBP), c) global LV longitudinal (GLS), circumferential (GCS) and radial (GRS) strain, d) the ratio PWV/GLS, as an index of ventricular-arterial interaction, e) myocardial work index (GWI) using speckle tracking imaging. Results Twelve months post-treatment, all patients improved PBR, PWV, GLS, GCS and GRS (p&lt;0.05). GLP-1RA, SGLT-2i and their combination showed a greater reduction of PBR, PWV and cSBP than insulin, despite a similar HbA1c reduction (p&lt;0.05). GLP-1RA or GLP-1RA+SGLT-2i provided a greater decrease of PWV/GLS (28.1% and 31% vs. 11.1% and 14.5%) and a greater increase of GWI (12.7% and 17.4% vs. 3.1% and 2%) compared with insulin or SGLT-2i. SGLT-2i or GLP-1RA+SGLT-2i showed a greater decrease of PWV (10.1% and 13%), cSBP than insulin or GLP-1RA (PWV: 3.6% and 8.6%) (p&lt;0.05 for all comparisons) (Table 1). The dual therapy showed the greatest effect on measured markers in patients with LVEF &lt;55% (p&lt;0.05). Conclusions Twelve-month treatment with GLP-1RA, SGLT-2i and their combination showed a greater improvement of vascular markers and effective cardiac work than insulin in T2DM. The combined therapy was superior to either insulin, or GLP-1RA and SGLT-2i separately. Funding Acknowledgement Type of funding source: None
