Background: Type 2 diabetes mellitus (DM) is associated with a considerable risk of cardiovascular and renal disease, including heart failure. Sodium–glucose cotransporter 2 (SGLT2) inhibitors have demonstrated unprecedented cardiorenal protective effects in large scale clinical trials of patients with or without diabetes and either established cardiovascular disease (CV) or multiple CV risk factors. Objective: Herein we aim to focus on the role of SGLT2 inhibitors regarding the improvement in heart failure outcomes and the proposed mechanisms of action by which these drugs confer their beneficial effect. Methods: PubMed, Embase and Google Scholar databases were searched to identify eligible articles which are comprehensively summarized and discussed. Results: The most commonly discussed mechanisms of action are diuresis and natriuresis, reduction in preload, afterload, and ventricular mass, as well as stimulation of erythropoietin production and improved myocardial energetics. SGLT2 inhibitors improve outcomes in patients with established heart failure (HF) and reduce the risk of death and HF admissions in patients with established chronic HF with reduced ejection fraction (HFrEF), either with or without diabetes. Conclusion: Potential key mechanisms that may explain the notable cardioprotective benefits of SGLT2 inhibitors have been outlined. These agents have recently received class Ia recommendation in specific groups of people with DM to lower the risk of hospitalization for HF and risk of death, while these benefits may also extend to people without diabetes. It remains to be seen whether they will also emerge as treatment approaches in the acute phase of CV episodes.

Abstract Four large-scale trials in type 2 diabetes have shown that sodium-glucose cotransporter 2 (SGLT2) inhibitors prevent the occurrence of serious heart failure events. Additionally, the DAPA-HF trial demonstrated a benefit of dapagliflozin to reduce major adverse outcomes in patients with established heart failure with a reduced ejection fraction. The trial sheds light on potential mechanisms. In DAPA-HF, the benefits of dapagliflozin on heart failure were seen to a similar extent in both patients with or without diabetes, thus undermining the hypothesis that these drugs mitigate glycemia-related cardiotoxicity. The action of SGLT2 inhibitors to promote ketogenesis is also primarily a feature of the action of these drugs in patients with diabetes, raising doubts that enhanced ketogenesis contributes to the benefit on heart failure. Also, dapagliflozin does not have a meaningful effect to decrease circulating natriuretic peptides, and it did not potentiate the actions of diuretics in DAPA-HF; moreover, intensification of diuretics therapy does not reduce cardiovascular death, questioning a benefit of SGLT2 inhibitors that is mediated by an action on renal sodium excretion. Finally, although hematocrit increases with SGLT2 inhibitors might favorably affect patients with coronary artery disease, in DAPA-HF, the benefit of dapagliflozin was similar in patients with or without an ischemic cardiomyopathy; furthermore, increases in hematocrit do not favorably affect the clinical course of patients with heart failure. Therefore, the results of DAPA-HF do not support many currently-held hypotheses about the mechanism of action of SGLT2 inhibitors in heart failure. Ongoing trials are likely to provide further insights.

Sodium Glucose Cotransporter

Selective sodium–glucose cotransporter 2 (SGLT2) inhibitors reduced the risk of hospitalization for heart failure in patients with or without type 2 diabetes (T2DM) in large-scale clinical trials. The exact mechanism of action is currently unclear. The dual SGLT1/2 inhibitor sotagliflozin not only reduced hospitalization for HF in patients with T2DM, but also lowered the risk of myocardial infarction and stroke, suggesting a possible additional benefit related to SGLT1 inhibition. In fact, several preclinical studies suggest that SGLT1 plays an important role in cardiac pathophysiological processes. In this review, our aim is to establish the clinical significance of myocardial SGLT1 inhibition through reviewing basic research studies in the context of SGLT2 inhibitor trials.

Beneficial Effects

Heart failure (HF) is a common complication or late-stage manifestation of various heart diseases. Numerous risk factors and underlying causes may contribute to the occurrence and progression of HF. The pathophysiological mechanisms of HF are very complicated. Despite accumulating advances in treatment for HF during recent decades, it remains an intractable clinical syndrome with poor outcomes, significantly reducing the quality of life and expectancy of patients, and imposing a heavy economic burden on society and families. Although initially classified as antidiabetic agents, sodium-glucose co-transporter 2 (SGLT2) inhibitors have demonstrated reduced the prevalence of hospitalization for HF, cardiovascular death, and all-cause death in several large-scale randomized controlled clinical trials. These beneficial effects of SGLT-2 inhibitors can be attributed to multiple hemodynamic, inflammatory and metabolic mechanisms, not only reducing the serum glucose level. SGLT2 inhibitors have been used increasingly in treatment for patients with HF with reduced ejection fraction due to their surprising performance in improving the prognosis. In addition, their roles and mechanisms in patients with HF with preserved ejection fraction or acute HF have also attracted attention. In this review article, we discuss the possible mechanisms and applications of SGLT2 inhibitors in HF.

Sodium Glucose Cotransporter

: Sodium-glucose cotransporter 2 (SGLT2) inhibitors are a class of anti-diabetic agents that block the reabsorption of glucose in the proximal convoluted tubule of the nephron, thereby contributing to glycosuria and lowering blood glucose levels. SGLT2 inhibitors have been associated with improved cardiovascular outcomes in patients with diabetes, including a reduced risk of cardiovascular death and hospitalizations for heart failure. Recently, DAPA-HF and EMPEROR REDUCED trials showed the beneficial cardiovascular effect of SGLT2 inhibitors in patients with heart failure with consistently reduced ejection fraction (HFrEF) regardless of the presence of diabetes. Moreover, some exploratory studies suggested that these drugs improve Left Ventricular (LV) systolic function and oppose LV adverse remodeling in patients with HFrEF. However, the exact mechanisms that mediated for this benefit are not fully understood. Beyond glycemic control, enhanced natriuresis, increased erythropoiesis, improved endothelial function, changes in myocardial metabolism, anti-inflammatory and anti-oxidative properties may all play an active role in SGLT2 inhibitors’ cardiovascular benefits. A deep understanding of the pathophysiological interplay is key to define which HF phenotype could benefit more from SGLT2 inhibitors. Current clinical evidence on the comparison of different HF etiologies is limited to posthoc subgroup analysis of DAPA-HF and EMPEROR-REDUCED, which showed similar outcomes in patients with or without ischemic HF. On the other hand, in earlier studies of patients suffering from diabetes, rates of classic ischemic endpoints, such as myocardial infarction, stroke or coronary revascularization, did not differ between patients treated with SGLT2 inhibitors or placebo. The aim of this review is to discuss whether SGLT2 inhibitors may improve prognosis in patients with ischemic HF, not only in terms of reducing re-hospitalizations and improving left ventricular function but also by limiting coronary artery disease progression and ischemic burden.

Abstract Background Vasoplegia has been reported in patients receiving angiotensin receptor-neprilysin inhibitors (ARNI) with heart failure with reduced ejection fraction (HFrEF). We present a case of vasoplegic shock after initiation of ARNI in a hospitalized 65-year-old man recovering from cardiogenic shock (CS) and acute kidney injury (AKI). Case summary A 65-year-old man with HFrEF presented to a community hospital with CS with evidence of poor perfusion with a lactate of 5.6 mmol/L and creatinine (Cr) 125 µmol/L. He was treated with intravenous furosemide infusion. Subsequently, his lactate normalized but he developed an AKI with a Cr of 176 µmol/L. He was then started on ARNI and beta blockers. Over the next 24 h, he developed a vasoplegic shock necessitating multiple vasopressors and a transfer to a tertiary academic centre. With supportive therapy, his vasoplegic shock improved and he was discharged home. Discussion PARADIGM-HF found that the introduction of an ARNI in patients with ambulatory symptomatic HFrEF reduces the risk of death and heart failure hospitalization. Most recently, PIONEER-HF showed that ARNI reduced N-terminal pro-B-type natriuretic peptide levels at 4 and 8 weeks, without significantly different rates of medication-related adverse effects. However, thus far, no clinical trials have examined the role of ARNI in CS. Our case report highlights the risk of vasoplegic shock caused by initiation of ARNI in patients hospitalized with CS especially in whom renal and hepatic impairment is present.

Diabetes and heart failure (HF) are closely linked, with one causing a worse prognosis in the other. The majority of anti-hyperglycaemic agents primarily reduce risk of ischaemic microvascular events without targeting the mechanisms involved for diabetes cardiomyopathy and HF. Sodium–glucose cotransporter-2 (SGLT2) inhibitors have emerged as a novel class of glucose-lowering agents that have consistently reduced HF hospitalisations, unlike other agents. The authors discuss the current evidence and highlight possible future directions for the role of SGLT2 inhibitors in HF prevention.

AbstractIn different large-scale clinic outcome trials, sodium (Na+)/glucose co-transporter 2 (SGLT2) inhibitors showed profound cardiac- and renal-protective effects, making them revolutionary treatments for heart failure and kidney disease. Different theories are proposed according to the emerging protective effects other than the original purpose of glucose-lowering in diabetic patients. As the ATP-dependent primary ion transporter providing the Na+ gradient to drive other Na+-dependent transporters, the possible role of the sodium–potassium adenosine triphosphatase (Na/K-ATPase) as the primary ion transporter and its signaling function is not explored.

Substantial Risk

Heart failure is associated with a substantial risk of mortality and morbidity. Findings from recent cardiovascular outcome trials have shown promise for sodium-glucose cotransporter-2 (SGLT2) inhibitors in preventing heart failure in patients with type 2 diabetes mellitus (T2DM). Notably, the benefits of SGLT2 inhibitors were consistent despite the presence of risk factors like atherosclerosis. Increasing evidence suggests that SGLT2 inhibitors may confer their cardioprotective effects through multiple mechanisms, ranging from improving cardiac and vascular performance to metabolism. The reduction of heart failure risk by SGLT2 inhibitors may also be attributed to the preservation of renal function. Indeed, renal insufficiency is a frequent comorbidity of patients with heart failure and T2DM; hence, the natriuretic and kidney protective effects offered by SGLT2 inhibitors may contribute to limiting adverse cardiac outcomes. In this article, we discuss the latest findings from the cardiovascular and renal outcome trials, paying special attention to the interlink between heart and kidney function, and how effective treatment of heart failure—irrespective of T2DM diagnosis—may require agents that offer both cardiac and renal protection.
