Abstract
Cardiovascular diseases are caused by pathological cardiac remodeling, which involves fibrosis, inflammation and cell dysfunction. This includes autophagy, apoptosis, oxidative stress, mitochondrial dysfunction, changes in energy metabolism, angiogenesis and dysregulation of signaling pathways. These changes in heart structure and/or function ultimately result in heart failure. In an effort to prevent this, multiple cardiovascular outcome trials have demonstrated the cardiac benefits of sodium‑glucose cotransporter type 2 inhibitors (SGLT2is), hypoglycemic drugs initially designed to treat type 2 diabetes mellitus. SGLT2is include empagliflozin and dapagliflozin, which are listed as guideline drugs in the 2021 European Guidelines for Heart Failure and the 2022 American Heart Association/American College of Cardiology/Heart Failure Society of America Guidelines for Heart Failure Management. In recent years, multiple studies using animal models have explored the mechanisms by which SGLT2is prevent cardiac remodeling. This article reviews the role of SGLT2is in cardiac remodeling induced by different etiologies to provide a guideline for further evaluation of the mechanisms underlying the inhibition of pathological cardiac remodeling by SGLT2is, as well as the development of novel drug targets.

Abstract
OBJECTIVES We systematically reviewed UK cardiovascular disease (CVD) randomized controlled trial (RCT) protocols to identify the proportion featuring eligibility criteria that may disproportionately exclude ethnic minority (EM) participants. METHODS We searched MEDLINE, Embase, and Cochrane Library databases, January 2014-June 2022, to identify UK CVD RCT protocols. We extracted nonclinical eligibility criteria from trial protocols and inductively categorized the trials by their language, consent, and broad (ambiguous) criteria. Findings are narratively reported. RESULTS Of the seventy included RCT protocols, most (87.1%; 61/70) mentioned consent within the eligibility criteria, with more than two-thirds (68.9%; 42/61) indicating a requirement for 'written' consent. Alternative consent pathways that can aid EM participation were absent. English language requirement was present in 22.9% (16/70) of the studies and 37.1% (26/70) featured broad criteria that are open to interpretation and subject to recruiter bias. Only 4.3% (3/70) protocols mentioned the provision of translation services. CONCLUSION Most UK CVD trial protocols feature eligibility criteria that potentially exclude EM groups. Trial eligibility criteria must be situated within a larger inclusive recruitment framework, where ethnicity is considered alongside other intersecting and disadvantaging identities.

Abstract
BACKGROUND Anemia associated with heart failure is frequent and can exacerbate the symptoms of heart failure. Dapagliflozin is the first SGLT-2 inhibitor with significant cardiovascular protection. However, the effect of dapagliflozin on anemia in elderly patients with heart failure is unknown. OBJECTIVE We aimed to study the effect of dapagliflozin on anemia in elderly patients with heart failure by bioinformatics analysis. METHODS The target genes were determined, followed by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. The protein-protein interaction (PPI) network and modules were constructed. The dapagliflozin-targets network in anemia and heart failure was constructed. Molecular docking experiments between dapagliflozin and its key target AKT1 were performed. RESULTS We found 1 dapagliflozin related target gene and 2 disease related genes. Totally, 134 target genes of dapagliflozin on anemia in elderly patients with heart failure were determined. The pathways may involve lipid and atherosclerosis, AGE-RAGE signaling pathway in diabetic complications, hepatitis B, insulin signaling pathway, fluid shear stress and atherosclerosis, neurotrophin signaling pathway, insulin resistance, toxoplasmosis, colorectal cancer, and EGFR tyrosine kinase inhibitor resistance. The hub genes in network were AKT1, TP53, GAPDH, TNF, CASP3, EGFR, and MAPK3. The structure of dapagliflozin and AKT1 molecular docking was exhibited. CONCLUSIONS The hub genes in network were AKT1, TP53, GAPDH, TNF, CASP3, EGFR, and MAPK3. The structure of dapagliflozin and AKT1 molecular docking was exhibited.

Abstract
The incidence of ischemic heart disease is 2-3 times higher in diabetic patients. However, the effect of dapagliflozin on ischemia-reperfusion myocardial injury in diabetic rats has not been studied. We examined the effects of dapagliflozin on myocardial IR injury in streptozotocin-nicotinamide-induced diabetic rats. Rats were divided into four groups (n = 7 in each group): control, control-dapagliflozin, diabetes, and diabetes-dapagliflozin. Dapagliflozin (1.5 mg/kg/day) was administered concomitantly in drinking water for 2 months. The hearts were perfused in a Langendorff's apparatus at 2 months and assessed before (baseline) and after myocardial IR for the following parameters: left ventricular developed pressure (LVDP), minimum and maximum rates of pressure change in the left ventricle (±dP/dt), endothelial nitric oxide (NO) synthase (eNOS) and inducible NO synthase (iNOS) mRNA expressions, creatine kinase MB (CK-MB) and troponin imyocardial enzyme extravasation, and lactate dehydrogenase. The recovery of LVDP and ±dP/dt in diabetic rats was lower than that in controls but near normal after dapagliflozin treatment. Diabetic rats had decreased eNOS expression and increased iNOS expression at baseline and after IR, whereas dapagliflozin normalized these parameters after IR. Compared with controls, cardiac NOx levels were initially lower in diabetic patients but higher after IR. Baseline MDA levels were higher in diabetic rats after IR, whereas cardiac NOx levels decreased after treatment with dapagliflozin. Dapagliflozin protects the diabetic rat heart from ischemia-reperfusion myocardial injury by regulating the expression of eNOS and iNOS and inhibiting cardiac lipid peroxidation.

Abstract
Sodium-glucose cotransporter 2 inhibitors (SGLT2is) are newly emerging insulin-independent anti-hyperglycemic agents that work independently of β-cells. Quite a few large-scale clinical trials have proven the cardiovascular protective function of SGLT2is in both diabetic and non-diabetic patients. By searching all relevant terms related to our topics over the previous 3 years, including all the names of agents and their brands in PubMed, here we review the mechanisms underlying the improvement of heart failure. We also discuss the interaction of various mechanisms proposed by diverse works of literature, including corresponding and opposing viewpoints to support each subtopic. The regulation of diuresis, sodium excretion, weight loss, better blood pressure control, stimulation of hematocrit and erythropoietin, metabolism remodeling, protection from structural dysregulation, and other potential mechanisms of SGLT2i contributing to heart failure improvement have all been discussed in this manuscript. Although some remain debatable or even contradictory, those newly emerging agents hold great promise for the future in cardiology-related therapies, and more research needs to be conducted to confirm their functionality, particularly in metabolism, Na+-H+ exchange protein, and myeloid angiogenic cells.

Abstract
AIMS To systematically review randomized controlled trials assessing effects of sodium-glucose cotransporter 2 inhibitors (SGLT2is) on hospitalization for heart failure (HHF) and cardiac structure/function and explore randomized controlled trial (RCT)-derived evidence for SGLT2i efficacy mechanisms in heart failure (HF). METHODS AND RESULTS Systematic searches of Medline and Embase were performed. In seven trials [3730-17 160 patients; low risk of bias (RoB)], SGLT2is significantly reduced the relative risk of HHF by 27-39% vs. placebo, including in two studies in patients with HF with reduced ejection fraction with or without type-2 diabetes mellitus (T2DM). Improvements in conventional cardiovascular risk factors, including glycaemic levels, cannot account for these effects. Five trials (56-105 patients; low RoB) assessed the effects of 6-12 months of SGLT2i treatment on left ventricular structure/function; four reported significant improvements vs. placebo, and one did not. Five trials (low RoB) assessed SGLT2i treatment effects on serum N-terminal pro B-type natriuretic peptide levels; significant reductions vs. placebo were reported after 8-12 months (two studies; 3730-4744 patients) but not ≤12 weeks (three studies; 80-263 patients). Limited available RCT-derived evidence suggests various possible cardioprotective SGLT2i mechanisms, including improved haemodynamics (natriuresis and reduced interstitial fluid without blood volume contraction/neurohormonal activation) and vascular function, enhanced erythropoiesis, reduced tissue sodium and epicardial fat/inflammation, decreased sympathetic tone, and beneficial changes in cellular energetics. CONCLUSIONS Sodium-glucose cotransporter 2 inhibitors reduce HHF regardless of T2DM status, and reversal of adverse left ventricular remodelling likely contributes to this efficacy. Hypothesis-driven mechanistic trials remain sparse, although numerous trials are planned or ongoing.

Abstract
Sodium-glucose cotransporter-2 inhibitors (SGLT2i) are a relatively novel class of drug for treating type 2 diabetes mellitus (T2DM) that inhibits glucose reabsorption in the renal proximal tubule to promote glycosuria and reduce blood glucose levels. SGLT2i has been clinically indicated for treating T2DM, with numerous recent publications focussing on both primary and secondary prevention of cardiovascular and renal events in Type 2 diabetic patients. The most recent clinical trials showed that SGLT2i have moderately significant beneficial effects on atherosclerotic major adverse cardiovascular events (MACE) in patients with histories of atherosclerotic cardiovascular disease. In this review and analysis, SGLT2i have however demonstrated clinically significant benefits in reducing hospitalisation for heart failure and worsening of chronic kidney disease (CKD) irrespective of pre-existing atherosclerotic cardiovascular disease or previous heart failure history. A meta-analysis suggests that all SGLT2 inhibitors demonstrated the therapeutic benefit on all-cause and cardiovascular mortality, as shown in EMPAREG OUTCOME study with a significant decrease in myocardial infarction, without increased stroke risk. All the above clinical trial recruited type 2 diabetic patients. This article aims to postulate and review the possible primary prevention role of SGLT2i in healthy individuals by reviewing the current literature and provide a prospective overview. The emphasis will include primary prevention of Type 2 Diabetes, Heart Failure, CKD, Hypertension, Obesity and Dyslipidaemia in healthy individuals, whom are defined as healthy, low or intermediate risks patients.

Abstract
Despite the currently established treatment for heart failure (HF), HF remains a growing public healthcare problem with an increasing burden. Therefore, novel therapeutic innovations are needed to overcome this issue and improve HF prognosis. Sodium-glucose co-transporter-2 inhibitors (SGLT2i) are state-of-the-art in type 2 diabetes mellitus management. They inhibit the reabsorption of glucose from the proximal renal tubules, leading to increased glycosuria and decreased plasma glucose levels. SGLT2i use is growing significantly, especially after recent clinical trials demonstrating favorable cardiovascular and renal protective effects independently of blood glucose-lowering. The mechanisms by which SGLT2i demonstrate their cardio-renal protective effects remain incompletely understood but are thought to be related to potential diuretic and natriuretic effects along with other mechanisms that will be discussed in this article. Over the past few years, there has been significant research on the safety, efficacy, and quality of this class of medications. Here, we review the current guideline-directed medical therapy for HF, focus on SGLT2i mechanism of action and potential role in HF patients, and finally summarize the cardiovascular clinical trials with SGLT2.

Abstract
PURPOSE Diabetes mellitus (DM) is a major risk factor for the development of heart failure (HF). Sodium-glucose co-transporter 2 (SGLT2) inhibitors have demonstrated consistent benefits in the reduction of hospitalization for HF in patients with DM. However, the pharmacological mechanism is not clear. To investigate the mechanisms of SGLT2 inhibitors in DM with HF, we performed target prediction and network analysis by a network pharmacology method. METHODS We selected targets of SGLT2 inhibitors and DM status with HF from databases and studies. The "Drug-Target" and "Drug-Target-Disease" networks were constructed using Cytoscape. Then the protein-protein interaction (PPI) was analyzed using the STRING database. Gene Ontology (GO) biological functions and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways were performed to investigate using the Bioconductor tool for analysis. RESULTS There were 125 effective targets between SGLT2 inhibitors and DM status with HF. Through further screening, 33 core targets were obtained, including SRC, MAPK1, NARS, MAPK3 and EGFR. It was predicted that the Rap1 signaling pathway, MAPK signaling pathway, EGFR tyrosine kinase inhibitor resistance, AGE-RAGE signaling pathway in diabetic complications and other signaling pathways were involved in the treatment of DM with HF by SGLT2 inhibitors. CONCLUSION Our study elucidated the possible mechanisms of SGLT2 inhibitors from a systemic and holistic perspective based on pharmacological networks. The key targets and pathways will provide new insights for further research on the pharmacological mechanism of SGLT2 inhibitors in the treatment of DM with HF.

Abstract
Heart failure (HF) continues to be a serious public health challenge despite significant advancements in therapeutics and is often complicated by multiple other comorbidities. Of particular concern is type 2 diabetes mellitus (T2DM) which not only amplifies the risk, but also limits the treatment options available to patients. The sodium-glucose linked cotransporter subtype 2 (SGLT2)-inhibitor class, which was initially developed as a treatment for T2DM, has shown great promise in reducing cardiovascular risk, particularly around HF outcomes - regardless of diabetes status.There are ongoing efforts to elucidate the true mechanism of action of this novel drug class. Its primary mechanism of inducing glycosuria and diuresis from receptor blockade in the renal nephron seems unlikely to be responsible for the rapid and striking benefits seen in clinical trials. Early mechanistic work around conventional therapeutic targets seem to be inconclusive. There are some emerging theories around its effect on myocardial energetics and calcium balance as well as on renal physiology. In this review, we discuss some of the cutting-edge hypotheses and concepts currently being explored around this drug class in an attempt better understand the molecular mechanics of this novel agent.

Effects of sodium-glucose cotransporter type 2 inhibitors on cardiovascular, renal, and safety outcomes in patients with cardiovascular disease: a meta-analysis of randomized controlled trials.

Abstract
Background Controlled studies and observational studies have shown that sodium-glucose cotransporter type 2 inhibitors (SGLT-2i) are beneficial for the survival of patients with heart failure (HF). However, it is unclear whether SGLT-2i can provide benefit in patients with other cardiovascular diseases. Here, we conducted a systematic review and meta-analysis to determine the outcomes of cardiovascular, renal, and safety outcomes of SGLT-2i administration in patients with cardiovascular diseases. Methods We searched PubMed, EMBASE, Cochrane Library, Web of Science databases, and ClinicalTrials.gov databases for randomised controlled trials written in English from inception until November 1, 2020. Two reviewers independently identified randomised controlled trials comparing the effects of SGLT-2i in patients with cardiovascular disease with or without diabetes. Primary outcomes were cardiovascular outcomes and renal outcomes. Secondary outcomes were safety outcomes, including adverse endocrine outcomes and adverse infection outcomes. The effects of SGLT-2i were evaluated using RevMan5.3 software. The Cochrane risk of bias tool was used to assess study quality. Results We identified 10 randomised controlled trials (25,108 patients in the SGLT-2i group and 18,574 patients in the placebo group). Meta-analysis revealed that SGLT-2i treatment significantly reduced all-cause mortality, cardiovascular mortality, and hospitalisation for heart failure (HHF) in patients with cardiovascular disease (all-cause mortality relative risk [RR]: 0.86; 95% confidence interval [CI] 0.81–0.91; P < 0.00001; I2 = 0%; cardiovascular mortality RR: 0.85; 95% CI 0.79–0.92; P < 0.0001; I2 = 26%; HHF RR: 0.69; 95% CI 0.64–0.81; P < 0.00001; I2 = 0%). In patients with HF, mortality and HHF after SGLT-2i treatment for HF with reduced ejection fraction were significantly reduced, whereas HF with preserved ejection fraction did not differ compared with placebo treatment. Moreover, SGLT-2i induced a lower incidence of renal damage and myocardial infarction than the placebo group; however, the risk of infection, amputation, volume depletion, and diabetic ketoacidosis was higher. Conclusions SGLT-2i had significant clinical effects on cardiovascular outcomes and significantly influenced acute kidney injury. The effects of SGLT-2i on cardiovascular disease were independent of diabetic status. Sotagliflozin could have advantages over other SGLT-2i in lowering HHF.

Abstract
Sodium-glucose co-transporter 2 inhibitors (SGLT2i) are a new drug class designed to treat patients with type 2 diabetes (T2D). However, cardiovascular outcome trials showed that SGLT2i also offer protection against heart failure (HF)-related events and cardiovascular mortality. These benefits appear to be independent of glycaemic control and have recently been demonstrated in the HF population with reduced ejection fraction (HFrEF), with or without T2D. This comprehensive, evidence-based review focuses on the published studies concerning HF outcomes with SGLT2i, discussing issues that may underlie the different results, along with the impact of these new drugs in clinical practice. The potential translational mechanisms behind SGLT2i cardio-renal benefits and the information that ongoing studies may add to the already existing body of evidence are also reviewed. Finally, we focus on practical management issues regarding SGLT2i use in association with other T2D and HFrEF common pharmacological therapies. Safety considerations are also highlighted. Considering the paradigm shift in T2D management, from a focus on glycaemic control to a broader approach on cardiovascular protection and event reduction, including the potential for wide SGLT2i implementation in HF patients, with or without T2D, we are facing a promising time for major changes in the global management of cardiovascular disease.

Abstract
BACKGROUND Although not fully understood, diabetes mellitus is thought to be associated with cardiac fibrosis and stiffness due to alteration of myocardial extracellular matrix. Newer cardiac magnetic resonance techniques may be able to identify extracellular matrix expansion by measuring extracellular volume fraction (ECV). We used cardiac magnetic resonance to evaluate the association of alteration in the extracellular matrix with diabetic status and its implications on incident heart failure events and all-cause mortality. METHODS We studied 442 patients who underwent comprehensive contrast cardiac magnetic resonance to assess cardiac morphology and function, left ventricular replacement fibrosis, and pre-post contrast T1 mapping to quantify ECV. The cohort did not have coexisting pathologies associated with ECV alteration. We categorized our final cohort based on diabetic status using criteria from the American Diabetic Association. Subsequent heart failure hospitalization and all-cause death were ascertained. RESULTS Our patients were predominantly white with a median age of 57 with 48% being men. Compared with nondiabetes mellitus, diabetes mellitus was significantly associated with elevated ECV after adjusting for clinical and imaging covariates: β coefficient 1.33 (95% CI, 0.22-2.44); P=0.02. Over a median follow-up of 24.5 (interquartile range, 14.8-33.4) months, 52 deaths and 24 heart failure events occurred. Patients with diabetes mellitus and elevated ECV had the worst outcomes compared with patients with diabetes mellitus and normal ECV or nondiabetics. Elevated ECV remained an independent predictor of outcomes (hazard ratio, 3.31 [95% CI, 1.93-5.67]; P<0.001) after adjusting for covariates. CONCLUSIONS Elevated ECV is an independent predictor of mortality among patients with diabetes mellitus and may have an additive effect with diabetes mellitus on outcomes. ECV may represent a novel noninvasive biomarker to evaluate severity of diabetic heart disease.

Abstract
OBJECTIVE To determine the effects of dapagliflozin in patients with heart failure (HF) and type 2 diabetes mellitus (T2DM) on left ventricular (LV) remodeling using cardiac MRI. RESEARCH DESIGN AND METHODS We randomized 56 patients with T2DM and HF with LV systolic dysfunction to dapagliflozin 10 mg daily or placebo for 1 year, on top of usual therapy. The primary end point was difference in LV end-systolic volume (LVESV) using cardiac MRI. Key secondary end points included other measures of LV remodeling and clinical and biochemical parameters. RESULTS In our cohort, dapagliflozin had no effect on LVESV or any other parameter of LV remodeling. However, it reduced diastolic blood pressure and loop diuretic requirements while increasing hemoglobin, hematocrit, and ketone bodies. There was a trend toward lower weight. CONCLUSIONS We were unable to determine with certainty whether dapagliflozin in patients with T2DM and HF had any effect on LV remodeling. Whether the benefits of dapagliflozin in HF are due to remodeling or other mechanisms remains unknown.

Abstract
Patients with type 2 diabetes (T2D) are often overweight/obese and affected by arterial hypertension, dyslipidaemia, and have high serum levels of uric acid. Moreover, T2D patient have a higher risk of developing cardiovascular or renal complications, which are leading causes of morbidity and mortality in this population. Sodium-glucose cotransporter-2 inhibitors (SGLT2i) are a new class of glucose-lowering medications that block the reabsorption of glucose in the kidney, thereby increasing urinary glucose excretion, and lowering blood glucose levels. The beneficial effects of SGLT2 inhibition extend beyond glycaemic control, and include improvement in blood pressure, body weight, uric acid concentrations, liver steatosis, oxidative stress, and inflammation. In dedicated cardiovascular outcome trials, SGLT2i treatment was associated with a significant reduction in the rate of cardiovascular events and renal endpoints. In this review, we summarize the evidence for extra-glycemic effects of SGLT2i and the potential mechanisms driving cardiorenal protection exerted by this class of medications.

Abstract
Introduction: Sodium-glucose cotransporter 2 (SGLT-2) inhibitors are
the newest class of oral antihyperglycemic medications approved for the
treatment of type 2 diabetes mellitus (DM2). Although they are not approved for
use in type 1 diabetes mellitus (DM1), SGLT2 inhibitors may help DM1 patients
achieve their HbA1c goals by decreasing their insulin requirements, without
inducing hypoglycemic episodes and weight gain. Methods: We
conducted a retrospective chart review of 26 patients with DM1 treated with
off-label SGLT-2 inhibitors. The primary objective was change in HbA1c and
weight. The secondary objective was assessing the effect on insulin
requirements, blood pressure, and lipid profile. Results:
Improvement in HbA1c level was seen in 20 of the 26 patients (77%) after
initiation of SGLT-2 inhibitors. The average decrease in HbA1c was 0.32%
(P = .032), with changes seen as early as 1 month
posttherapy and maintained with continued SGLT-2 inhibitor use. There was a
trend toward weight loss that was not significant. No significant changes in
blood pressure or lipid profiles were seen except for a slight increase in
low-density lipoprotein (P = .049). No patient developed
euglycemic diabetic ketoacidosis. Three patients discontinued therapy due to
uncontrolled genital yeast infections. Conclusion: SGLT-2
inhibitors can be a useful adjunctive therapy in patients with DM1 to improve
glycemic control and weight. Although our study did not show any significant
changes in the metabolic profile and insulin requirements in these patients, a
larger sample size may yield different results.

Abstract
Background: Heart failure (HF) is associated with type 2 diabetes mellitus (T2DM). Antihyperglycemic drugs have interaction with heart failure among diabetic patients. To date, the data on real world use of diabetic medication in Malaysian heart failure patients with T2DM has not been elucidated. Objective: This study aims to identify the prescribing pattern of antihyperglycemic regimens in HF patients with T2DM, and to investigate the association between glycemic control and other factors such as demographic and clinical characteristics with left ventricular ejection fraction (LVEF) in these patients. Methods: This retrospective observational study involved patients diagnosed to have HF and T2DM who were seen in the outpatient clinic in a government tertiary hospital in Malaysia. Patients receiving at least one oral antidiabetic agent and/or insulin for at least 3 months prior were included. The differences and association between study outcomes were examined and analyzed using Pearson's Chi-square test, One-Way ANOVA, Binary Logistic Regression and multiple Multinomial Logistic Regression models. Results: From July to December 2019, 194 patients were included in this study. The majority (52.1%) of the patients had HF with preserved ejection fraction (HFpEF), 20.6% had HF with mid-range EF (HFmrEF), and 27.3% had HF with reduced EF (HFrEF). Overall, metformin (59.8%) was the commonest antihyperglycemic agent prescribed, followed by insulins (54.0%), and sulphonylureas (44.9%). The most prescribed agents for HFpEF, HFmrEF, and HFrEF patients were metformin (65.3%), insulins (62.5%), and sulphonylureas (60.4%), respectively. The prescribing trend of sulphonylureas was found to be significantly associated with patients' LVEF status (p = 0.033). The odds for sulphonylurea prescription among the HFrEF patients were 2.42 times higher compared to the HFpEF patients [95% confidence interval [CI], 1.23-4.79]. There was no association found between glycemic control with patients' LVEF. Conclusion: Our findings reported metformin as the most commonly prescribed antihyperglycemic agent, sodium glucose linked transporter-2 (SGLT-2) inhibitor being under-prescribed, and detected poorly controlled diabetes in majority of patients with T2DM and HF. Understanding the prescribing pattern of antihyperglycemic agents supports the implementation of evidence-based treatment in HF patients with T2DM to improve patients' outcomes.

Abstract
Type 2 diabetes mellitus is one of the most common forms of the disease worldwide. Hyperglycemia and insulin resistance play key roles in type 2 diabetes mellitus. Renal glucose reabsorption is an essential feature in glycaemic control. Kidneys filter 160 g of glucose daily in healthy subjects under euglycaemic conditions. The expanding epidemic of diabetes leads to a prevalence of diabetes-related cardiovascular disorders, in particular, heart failure and renal dysfunction. Cellular glucose uptake is a fundamental process for homeostasis, growth, and metabolism. In humans, three families of glucose transporters have been identified, including the glucose facilitators GLUTs, the sodium-glucose cotransporter SGLTs, and the recently identified SWEETs. Structures of the major isoforms of all three families were studied. Sodium-glucose cotransporter (SGLT2) provides most of the capacity for renal glucose reabsorption in the early proximal tubule. A number of cardiovascular outcome trials in patients with type 2 diabetes have been studied with SGLT2 inhibitors reducing cardiovascular morbidity and mortality. The current review article summarises these aspects and discusses possible mechanisms with SGLT2 inhibitors in protecting heart failure and renal dysfunction in diabetic patients. Through glucosuria, SGLT2 inhibitors reduce body weight and body fat, and shift substrate utilisation from carbohydrates to lipids and, possibly, ketone bodies. These pleiotropic effects of SGLT2 inhibitors are likely to have contributed to the results of the EMPA-REG OUTCOME trial in which the SGLT2 inhibitor, empagliflozin, slowed down the progression of chronic kidney disease and reduced major adverse cardiovascular events in high-risk individuals with type 2 diabetes. This review discusses the role of SGLT2 in the physiology and pathophysiology of renal glucose reabsorption and outlines the unexpected logic of inhibiting SGLT2 in the diabetic kidney.

Abstract
Sodium-glucose cotransporter 2 (SGLT2) inhibitors are a unique class of oral anti-hyperglycaemic medications that act to reduce glucose reabsorption in the renal proximal tubules, thereby enhancing urinary glucose excretion. Large randomized placebo-controlled trials in people with diabetes at high cardiovascular risk have demonstrated that SGLT2 inhibitors reduce heart failure hospitalization within months of commencing therapy. These findings are of considerable interest, as diabetes is associated with an increased risk of both heart failure with reduced ejection fraction and heart failure with preserved ejection fraction. In addition, left ventricular (LV) hypertrophy and impaired diastolic function is thought to be more prevalent in people with diabetes. Although many hypotheses have been proposed, the underlying mechanisms through which SGLT2 inhibitors reduce the risk of heart failure in people with diabetes are not fully understood. Given the rapid reduction in heart failure hospitalization, it is conceivable that the benefits of SGLT2 inhibitors are due to favourable haemodynamic and metabolic effects on LV function. Several clinical studies have been conducted to investigate the effect of SGLT2 inhibitors on LV structure and function and have found that LV mass index and diastolic function improve following SGLT2 inhibitor therapy in people with type 2 diabetes. If these findings are confirmed in future studies utilizing novel cardiac imaging modalities and large randomized controlled trials, then this will bring new hope for the prevention and management of heart failure with preserved ejection fraction, for which no current treatments have been shown to reduce mortality. At the present time, SGLT2 inhibitors are indicated for the treatment of type 2 diabetes; however, the results of ongoing trials in participants with heart failure but without diabetes are eagerly awaited. The purpose of this review is to summarize current knowledge regarding the effects of SGLT2 inhibitors on LV function, particularly the findings from clinical studies, proposed biological mechanisms, and future directions.

Abstract
Type 2 diabetes (T2D) is associated with an increased risk of macro- and microvascular complications, including cardiovascular disease (CVD), heart failure (HF), and chronic kidney disease (CKD). Of the currently available glucose-lowering therapies, sodium-glucose cotransporter-2 inhibitors (SGLT-2is) are the only class to target the pathophysiologic increase in renal glucose reabsorption in patients with T2D. In CV outcomes trials of SGLT-2is in patients with T2D and established CVD or varying levels of CV risk, empagliflozin, canagliflozin, and dapagliflozin were associated with significant improvements in the risk of composite CV and renal outcomes compared with placebo that extended beyond their glycemic effects. Real-world observational studies have also reported improvements in CV outcomes with SGLT-2is compared with other glucose-lowering therapy in routine clinical practice. This review describes the pleiotropic effects of SGLT-2is and discusses the potential mechanisms for these effects as well as how they potentially provide benefits beyond glycemic control in patients with T2D. These favorable nonglycemic effects indicate that SGLT-2is may be of particular benefit in patients with diabetic complications, such as CVD, HF, or CKD. Ongoing large randomized trials in specific patient populations, including those with CVD, HF, or CKD (with or without T2D), may help to confirm the benefits of SGLT-2is in these patients and further elucidate the potential mechanisms of their pleiotropic effects.

Secondary analysis of a randomized placebo-controlled trial. Cardiovasc Diabetol 2019; 18:106. [PMID: 31412874 PMCID: PMC6694690 DOI: 10.1186/s12933-019-0910-5] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2019] [Accepted: 08/08/2019] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND AND AIMS Cardiovascular outcome trials have documented a strong benefit of sodium glucose cotransporter-2 inhibitors (SGLT2i) on the risk of hospitalization for heart failure (HF) in patients with type 2 diabetes (T2D) with or without established cardiovascular disease or prior history of HF. The mechanisms, however, are not entirely clear. We aimed to evaluate whether treatment with SGLT2i affected cardiac function using impedance cardiography (ICG) in a randomized placebo-controlled trial. MATERIALS AND METHODS Thirty-three patients with T2D were randomized to receive blind dapagliflozin 10 mg or matching placebo for 12-week on top of their ongoing glucose lowering medication regimen. Cardiac function was evaluated by resting ICG at baseline and at the end of the 12-week treatment period. ICG is a non-invasive technology based on the continuous measurement of thoracic electrical conductivity to process a cardiodynamic parameters related to fluid content, blood flow, cardiac function, and circulatory function. We also evaluated changes in glycaemic control, blood pressure, and body weight. RESULTS Thirty-one patients completed the study, 1 was excluded because ICG data was missing. Patients included in the final analysis were on average 63.4-year-old, with a known diabetes duration of 14.1 years and a baseline HbA1c of 8.2% (66 mmol/mol). 63.3% of patients had established cardiovascular disease (symptomatic or asymptomatic) and 36.7% had microangiopathy, but none had a prior history of HF. After 12 weeks, patients randomized to dapagliflozin, as compared to those randomized to placebo, showed improvements in HbA1c (- 1.2%; 13 mmol/mol), systolic blood pressure (- 3.7 mmHg), and body weight (- 3.3 kg). Based on ICG, in both groups, we detected no significant change in parameters of blood flow (stroke volume, cardiac output, cardiac index), systolic function (ejection fraction, acceleration and velocity indexes, systolic time ratio), circulatory function (systemic vascular resistance index), and fluid status (thoracic fluid content) after treatment. CONCLUSION This is the first study exploring cardiac effects of SGLT2i using ICG in T2D. We observed no change in cardiac function parameters estimated by ICG in T2D patients who received dapagliflozin versus placebo for 12 weeks. Trial registration ClinicalTrial.gov NCT02327039.

Abstract
BACKGROUND Reports that sodium glucose cotransporter 2 inhibitors decrease cardiovascular death and events in patients with diabetes have attracted attention in the cardiology field. We conducted a study of canagliflozin in patients with chronic heart failure and type II diabetes. METHODS Thirty-five Japanese patients with chronic heart failure and type II diabetes were treated with canagliflozin for 12 months. The primary endpoints were the changes of subcutaneous, visceral, and total fat areas at 12 months determined by computed tomography. Secondary endpoints included markers of glycemic control, renal function, and oxidative stress, as well as lipid parameters, atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), flow-mediated dilation (FMD), and echocardiographic left ventricular function. RESULTS All fat areas (subcutaneous, visceral, and total) showed a significant decrease at 12 months. ANP and BNP also decreased significantly, along with improvement of renal function, oxidized LDL, and E/e', FMD increased significantly after canagliflozin treatment. CONCLUSION Canagliflozin demonstrated cardiac and renal protective effects as well as improving oxidative stress, diastolic function, and endothelial function. This drug was effective in patients who had heart failure with preserved ejection fraction and could become first-line therapy for such patients with diabetes.

Abstract
Chronic heart failure (CHF) is a challenging burden on public health. Therapeutic strategies for CHF have developed rapidly in the past decades from conventional medical therapy, which mainly includes administration of angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, beta-blockers, and aldosterone antagonists, to biomedical engineering methods, which include interventional engineering, such as percutaneous balloon mitral valvotomy, percutaneous coronary intervention, catheter ablation, biventricular pacing or cardiac resynchronization therapy (CRT) and CRT-defibrillator use, and implantable cardioverter defibrillator use; mechanical engineering, such as left ventricular assistant device use, internal artery balloon counterpulsation, cardiac support device use, and total artificial heart implantation; surgical engineering, such as coronary artery bypass graft, valve replacement or repair of rheumatic or congenital heart diseases, and heart transplantation (HT); regenerate engineering, which includes gene therapy, stem cell transplantation, and tissue engineering; and rehabilitating engineering, which includes exercise training, low-salt diet, nursing, psychological interventions, health education, and external counterpulsation/enhanced external counterpulsation in the outpatient department. These biomedical engineering therapies have greatly improved the symptoms of CHF and life expectancy. To date, pharmacotherapy, which is based on evidence-based medicine, large-scale, multi-center, randomized controlled clinical trials, is still a major treatment option for CHF; the current interventional and mechanical device engineering treatment for advanced CHF is not enough owing to its individual status. In place of HT or the use of a total artificial heart, stem cell technology and gene therapy in regenerate engineering for CHF are very promising. However, each therapy has its advantages and disadvantages, and it is currently possible to select better therapeutic strategies for patients with CHF according to cost-efficacy analyses of these therapies. Taken together, we think that a new era of biomedical engineering for CHF has begun.

Abstract
BACKGROUND Dapagliflozin (DAPA) is an inhibitor of sodium-glucose cotransporter 2 prescribed for type 2 diabetes mellitus. DAPA plays a protective role against cardiovascular diseases. Nevertheless, the effect and mechanism of DAPA on pressure-overload-induced cardiac remodeling has not been determined. METHODS We used a transverse aortic constriction (TAC) induced cardiac remodeling model to evaluate the effect of DAPA. Twenty-four C57BL/6J mice were divided into 3 groups: Sham, TAC, and TAC + DAPA groups (n = 8, each). DAPA was administered by gavage (1.0 mg/kg/day) for 4 weeks in the TAC + DAPA group, and then the myocardial hypertrophy, cardiac systolic function, myocardial fibrosis, and cardiomyocyte apoptosis were evaluated. RESULTS Mice in TAC group showed increased heart weight/body weight, left ventricular (LV) diameter, LV posterior wall thickness, and decreased LV ejection fraction and LV fractional shortening. The collagen volume fraction and perivascular collagen area/luminal area ratio were significantly greater in the TAC group; the TUNEL-positive cell number and PARP level were also increased. We found that DAPA treatment reduced myocardial hypertrophy, myocardial interstitial and perivascular fibrosis, and cardiomyocyte apoptosis. Furthermore, DAPA administration inhibited phosphorylation of P38 and JNK in TAC group. In addition, the inhibited phosphorylation of FoxO1 in the TAC mice was upregulated by DAPA administration. CONCLUSION DAPA administration had a cardioprotective effect by improving cardiac systolic function, inhibiting myocardial fibrosis and cardiomyocyte apoptosis in a TAC mouse model, indicating that it could serve as a new therapy to prevent pathological cardiac remodeling in nondiabetics.

Abstract
INTRODUCTION Heart failure (HF) in type 2 diabetes mellitus (T2DM) poses a significant increase in mortality. Until recently, anti-diabetic drugs have not been shown to reduce hospitalization due to heart failure (hHF). While thiazolidinedione class and saxagliptin has shown a significantly increased risk, sodium-glucose linked co-transporter 2 inhibitors (SGLT-2Is) have demonstrated a significant reduction in the risk of hHF. Areas covered: We systematically searched the database of PubMed, Embase, ClinicalTrials.gov, and International conference presentation up to 25 December 2018 and retrieved all the studies that were conducted for ≥24 weeks and explicitly reported hHF outcome. Subsequently, we conducted the meta-analysis to study the effect of SGLT-2Is on hHF outcome in randomized controlled trials (RCTs), observational studies, and both. Expert opinion: The meta-analysis of RCTs (N = 34,322), observational studies (N = 15,36,339), and both (N = 15,70,661) demonstrated a significant decrease in hHF (OR 0.70, 0.64, 0.66, respectively, all p = 0.000) with SGLT-2Is compared to placebo or other anti-diabetes drugs in T2DM. A significant benefit in hHF (OR 0.68, p = 0.000) is also observed in patients with established HF (N = 3891) in sub-group meta-analysis of RCTs. Ongoing dedicated HF trials will further enlighten the merits of SGLT-2Is in patients with established heart failure (preserved or reduced) with or without T2DM.

Cardiovasc Diabetol 2019; 18:20. [PMID: 30819210 PMCID: PMC6393994 DOI: 10.1186/s12933-019-0828-y] [Citation(s) in RCA: 99] [Impact Index Per Article: 19.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/23/2018] [Accepted: 02/19/2019] [Indexed: 12/12/2022] Open
Abstract
Sotagliflozin is a dual sodium-glucose co-transporter-2 and 1 (SGLT2/1) inhibitor for the treatment of both type 1 (T1D) and type 2 diabetes (T2D). Sotagliflozin inhibits renal sodium-glucose co-transporter 2 (determining significant excretion of glucose in the urine, in the same way as other, already available SGLT-2 selective inhibitors) and intestinal SGLT-1, delaying glucose absorption and therefore reducing post prandial glucose. Well-designed clinical trials, have shown that sotagliflozin (as monotherapy or add-on therapy to other anti-hyperglycemic agents) improves glycated hemoglobin in adults with T2D, with beneficial effects on bodyweight and blood pressure. Similar results have been obtained in adults with T1D treated with either continuous subcutaneous insulin infusion or multiple daily insulin injections, even after insulin optimization. A still ongoing phase 3 study is currently evaluating the effect of sotagliflozin on cardiovascular outcomes (ClinicalTrials.gov NCT03315143). In this review we illustrate the advantages and disadvantages of dual SGLT 2/1 inhibition, in order to better characterize and investigate its mechanisms of action and potentialities.

Abstract
Heart failure (HF) is one of the leading causes of hospital readmissions and health care expenditures. With a vast degree of advancements in the clinical approach and diagnosis, its management protocol is limited in terms of enhancing quality of life and prognosis. Type 2 diabetes mellitus (T2DM) is considered as one of the commonly associated comorbid conditions in the HF population. The understanding of the molecular and metabolic models of HF has led to the utilization of therapeutic goals of T2DM in improving HF-related complications. In the recent era, SGLT-2 inhibitors have shown success in decreasing cardiovascular mortality in the T2DM population. This article will help the reviewer to comprehend the pathophysiology of HF and the potential role of SGLT-2 inhibitors in the management algorithm of HF and its associated risk factors in T2DM.

Abstract
Cardiovascular (CV) disease remains the leading cause of morbidity and mortality in individuals with type 2 diabetes mellitus (T2DM). However, conventional antihyperglycemic medications seem to have minimal effect on lowering CV risk despite achieving excellent reductions in glycated hemoglobin A1c and associated reductions in microvascular risk. Sodium-glucose cotransporter 2 (SGLT2) inhibitors have emerged as noteworthy antihyperglycemic agents with concomitant CV and renal protection in T2DM patients. In this comprehensive review, we present the key CV findings from major large-scale outcome trials of SGLT2 inhibitors to date. We also review the mechanistic studies that might explain the CV benefits of SGLT2 inhibition in patients with T2DM.

Abstract
Sodium-glucose cotransporter (SGLT)2 inhibitors have been demonstrated to reduce cardiovascular events, particularly heart failure, in cardiovascular outcome trials. Here, we review the proposed mechanistic underpinnings of this benefit. Specifically, we focus on the role of SGLT2 inhibitors in optimising ventricular loading conditions through their effect on diuresis and natriuresis, in addition to reducing afterload and improving vascular structure and function. Further insights into the role of SGLT2 inhibition in myocardial metabolism and substrate utilisation are outlined. Finally, we discuss two emerging themes: how SGLT2 inhibitors may regulate Na+/H+ exchange at the level of the heart and kidney and how they may modulate adipokine production. The mechanistic discussion is placed in the context of completed and ongoing trials of SGLT2 inhibitors in the prevention and treatment of heart failure in individuals with and without diabetes.

Abstract
The optimal treatment approach to patients with coronary artery disease (CAD), including those with type 2 diabetes mellitus (T2DM), has been extensively evaluated. Several trials of stable ischemic heart disease including patients with T2DM have demonstrated that medical management is comparable to revascularization in terms of mortality and rates of major adverse cardiovascular events (MACE). There has been a growing appreciation for optimal medical therapy's (OMT) role in improving clinical outcomes. It is vital to target T2DM patients to prevent or delay MACE events through advanced OMT, ultimately delaying if not avoiding the need for revascularization. There has been significant evolution in the development of pharmacologic management of T2DM patients. Sodium-glucose co-transporter-2 (SGLT2) inhibitors are a new pharmacologic therapy with tremendous potential to alter clinical practice and influence practice guidelines. SGLT2-inhibitors have great potential in reducing MACE in patients with T2DM and CAD. Empagliflozin should be considered as a part of OMT among these patients. If results similar to the EMPA-REG OUTCOMES trial are replicated in other trials, the use of these pharmacologic agents as a part of OMT may narrow the gap between revascularization and OMT alone in patients with T2DM and multi-vessel disease. Future studies on the role of SLGT-2 inhibitors with regard to heart failure outcomes are needed to elucidate the mechanisms and clinical effects in this vulnerable population.

Abstract
Resistant hypertension (RH) is a multifactorial disease associated with several target organ damage, such as microalbuminuria, left ventricular hypertrophy, and arterial stiffness. These subjects have high cardiovascular complications, especially when associated with diabetes condition. Sodium glucose cotransporter 2 (SGLT-2) inhibitors represent a new class of oral antidiabetic drugs that have shown positive effects in diabetics and even hypertensives subjects. Several studies demonstrated positive outcomes related to blood pressure levels, body weight, and glycemic control. Also found a reduction on microalbuminuria, cardiac and arterial remodeling process, and decrease in hospitalization care due heart failure. Despite these positive effects, the outcomes found for stroke were conflicted and tend neutral effect. Based on this, we sought to assess the pleiotropic effects of SGLT-2 inhibitors and the possible impact in RH subjects. In order to analyze the prospects of SGLT-2 inhibitors as a possible medication to complement the therapy manage of this high-risk class of patients.

Abstract
Background Asymptomatic left ventricular (LV) dysfunction is highly prevalent in type 2 diabetes patients. Unlike the other hypoglycemic drugs, SGLT2 inhibitors have shown potential benefits for reducing cardiovascular death and risk factors, aside from lowering plasma glucose levels. With this study we aim at determining whether the treatment with empagliflozin is associated with an improvement in LV functions in diabetic patients with asymptomatic LV dysfunction against Sitagliptin, which is presumably neutral on myocardial function. To determine changes in LV systolic and diastolic functions we will use speckle-tracking echocardiography, a novel sensitive, non-invasive, bedside method allowing the calculation of LV global longitudinal strain (GLS), an index of myocardial deformability, as well as 3D echocardiography, which allows a better evaluation of LV volumes and mass. Methods The EMPA-HEART trial will be a phase III, open label, active-controlled, parallel groups, single centre, exploratory study conducted in Pisa, Italy. A cohort of 75 diabetic patients with normal LV systolic (2D-Echo EF > 50%) and renal (eGFR sec MDRD > 60 ml/min/1.73 mq) functions and no evidence of valvular and/or ischemic heart disease will be randomized to either Empagliflozin 10 mg/die or Sitagliptin 100 mg/die. The primary outcome is to detect a change in GLS from baseline to 1 and 6 months after treatment initiation. The secondary outcomes include changes from baseline to 6 months in 3-D Echocardiography EF, left atrial volume and E/E′, VO2max as measured at cardiopulmonary test, cardiac autonomic function tests (R–R interval during Valsalva manoeuvre, deep-breathing, lying-to-standing), and the determination of a set of plasma biomarkers aimed at studying volume, inflammation, oxidative stress, matrix remodelling, myocyte strain and injury. Discussion SGLT2 inhibitors might affect myocardial functions through mechanisms acting both directly and indirectly on the myocardium. The set of instrumental and biohumoral tests of our study might actually detect the presence and entity of empagliflozin beneficial effects on the myocardium and shed light on the mechanisms involved. Further, this study might eventually provide information to design a clinical strategy, based on echocardiography and/or biomarkers, to select the patients who might benefit more from this intervention.

Abstract
Sodium-glucose co-transporter 2 inhibitors (SGLT2is) such as dapagliflozin, canagliflozin, and empagliflozin, are a promising new therapy in the treatment of type 2 diabetes mellitus (T2DM). SGLT2is can effectively reduce hyperglycemia thus improving glycemic control and they offer some beneficial effects on the cardiovascular (CV) system which can benefit patients with heart failure in addition toT2DM. The United States Food and Drug Administration requires new diabetes mellitus therapies to show a CV safety profile. Empagliflozin was the first SGLT2i that, when added to the standard of care for patients withT2DM at high risk for CV events, showed improved CV outcomes including reduced deaths from CV causes. Evidence also exists in favor of dapagliflozin for use in patients with T2DM with CV risk factors and heart failure. This review focuses on the effects, safety, and benefits of dapagliflozin on the CV system. Clinical trials have shown that dapagliflozin improves glycemic control without variation. It is safe and well-tolerated in the general population including older patients and those with high-risk CV factors or preexisting CV disease. There may be a renal protective role by an unknown mechanism. Dapagliflozin also lowers blood pressure due to its natriuresis effect. It improves levels of visceral fat and reduces body weight, and thus ameliorates metabolic syndrome. Dapagliflozin reduces oxidative stress and may delay atherosclerosis. Recent findings indicate SGLT2is may also reduce the atrial natriuretic peptide levels. Additional trials are required to validate these benefits and further evaluate if these are class effects. Trials such as DECLARE-TIMI58 are ongoing to evaluate the CV outcomes of dapagliflozin. More research is needed to design better antihyperglycemic regimes with clinical benefits in addition to good glycemic control.

Abstract
Heart failure has mortality rates that parallel those of breast cancer. Current management strategies include neurohormonal blockade, rate control measures, natriuretic peptide preservation, implantation of mechanical assist devices, and heart transplantation. Despite these strategies, however, the failing myocardium remains energy depleted. New strategies to promote metabolic recovery are being developed to potentially augment current treatment guidelines. For example, an unexpected finding of our own studies showed that mechanical unloading with assist devices in advanced-stage heart failure restored metabolic flux. Unfortunately, at that point it is too late for myocardial recovery. Traditional metabolic therapies addressing hyperglycemia have had limited long-term outcome benefit. Now, new therapeutic options are emerging based on increased understanding of the molecular mechanisms underlying energy depletion. Metabolic cardiac imaging combined with laboratory diagnostics could guide the design of individual therapeutic strategies. To date, agents that show benefit in select individuals include mimetics that stimulate glucagon-like peptide-1, inhibitors of sodium-glucose cotransporter receptors, drugs that limit fatty acid oxidation, and hormonal therapy in select individuals. This review will summarize mechanisms and investigations related to these metabolic approaches to heart failure.

Abstract
Background Recent studies reported that sodium glucose cotransporter 2 (SGLT2) inhibitors can potentially reduce the risk of cardiovascular mortality in patients with type 2 diabetes mellitus (T2DM). However, there is little or no information on the therapeutic effects of SGLT2 inhibitors on the progression of atherosclerosis. This dapagliflozin effectiveness on vascular endothelial function and glycemic control (DEFENCE) study was designed to determine the effects of dapagliflozin, a SGLT2 inhibitor, on endothelial function in patients with early-stage T2DM. Methods DEFENCE is a prospective, randomized, open-label, blinded-endpoint, parallel-group, comparative clinical trial. Between October 2015 and August 2016, 80 T2DM patients treated with 750 mg of metformin (hemoglobin A1c ≥6.0 and <8.0%, n = 80) were enrolled and randomized to receive either 1500 mg/day metformin (the metformin group, n = 40), or 750 mg/day metformin supplemented with 5 mg/day dapagliflozin (the dapagliflozin group, n = 40), for 16 weeks. The primary endpoint was a change in flow-mediated dilation (FMD) from baseline to the end of the 16-week treatment period. The secondary outcomes include changes in indexes of glycemic control, lipid metabolism, and oxidative stress, body composition, and safety evaluation. Results Although FMD tended to improve only in the dapagliflozin group, ΔFMD was comparable between the two groups. Analysis of patients with HbA1c >7.0% showed significant improvement of FMD in the dapagliflozin group than metformin group (P < 0.05). HbA1c, fasting plasma glucose, plasma glucagon, and body weight significantly decreased in both groups. Interestingly, urine 8-hydroxy-2′-deoxyguanosin, a biomarker of oxidative stress, was significantly lower in the dapagliflozin group than metformin group at 16 weeks (P < 0.001). Conclusions Dapagliflozin add-on therapy to metformin for 16 weeks improved endothelial function, as assessed by FMD, in patients with inadequately controlled early-stage T2DM. Improvement in oxidative stress may contribute to the improvement in FMD.

Abstract
The ultimate goal of treatment in people with diabetes mellitus is to prevent development of cardiovascular (CV) disease, resulting in prolongation of healthy life expectancy. Although impaired glycemic metabolism has a central role in its pathology, a number of studies have demonstrated that remedy for its imbalance cannot necessarily be accomplished as a therapeutic goal. A comprehensive medical approach against multi-factorial pathologies in diabetes, such as insulin resistance, obesity, hypertension, and dyslipidemia, in addition to diet and exercise therapy should be rather performed in the routine clinical setting. Along with such conceptual transition, what is required in anti-diabetes agents has also changed, and several anti-diabetes agents have been newly placed on the market in this decade. Such agents are required to undergo global pre- or post-marketing clinical trials assessing CV safety. A growing body of clinical evidence from those trials is now accumulating, and empagliflozin, a sodium-glucose cotransporter 2 (SGLT2) inhibitor, has first demonstrated significant risk reduction, relative to placebo, in CV death, overall mortality, and hospitalization for worsened heart failure in high-risk patients with diabetes mellitus. An SGLT2 inhibitor is a unique glucose-lowering agent and at the same time has multifaceted effects on hemodynamic and metabolic parameters beyond glycemic control. A major mode of action of SGLT2 inhibitors appears to be 'glycosuria' and 'natriuresis,' leading to amelioration of systemic glycemic homeostasis and potential cardio-renal protection. However, the precise mechanisms by which SGLT2 inhibitors affect benefits on the CV systems are yet to be fully elucidated. Thus, although we are now facing several unanswered concerns lurking behind the successful trial, SGLT2 inhibitors surely play several important roles in high-quality management of not only diabetes, but also CV medicine. This review summarizes our current understandings and future perspectives of SGLT2 inhibitors in CV medicine.
