Aims/hypothesisAfter coronary artery bypass graft (CABG) surgery in individuals with type 2 diabetes, there remains a considerable residual cardiovascular risk. In the EMPA-REG OUTCOME® trial in participants with type 2 diabetes and established cardiovascular disease, empagliflozin reduced the risk of cardiovascular death by 38%, all-cause mortality by 32%, hospitalisation for heart failure by 35% and incident or worsening nephropathy by 39% vs placebo when given in addition to standard of care. The aim of this post hoc analysis of the EMPA-REG OUTCOME® trial was to determine the effects of the sodium glucose cotransporter 2 inhibitor empagliflozin on cardiovascular events and mortality in participants with type 2 diabetes and a self-reported history of CABG surgery.MethodsThe EMPA-REG OUTCOME® trial was a randomised, double-blind, placebo-controlled trial. Participants with type 2 diabetes and established cardiovascular disease were randomised 1:1:1 to receive placebo, empagliflozin 10 mg or empagliflozin 25 mg, once daily, in addition to standard of care. In subgroups by self-reported history of CABG (yes/no) at baseline, we assessed: cardiovascular death; all-cause mortality; hospitalisation for heart failure; and incident or worsening nephropathy (progression to macroalbuminuria, doubling of serum creatinine, initiation of renal replacement therapy or death due to renal disease). Differences in risk between empagliflozin and placebo were assessed using a Cox proportional hazards model.ResultsAt baseline, 25% (1175/4687) of participants who received empagliflozin and 24% (563/2333) of participants who received placebo had a history of CABG surgery. In participants with a history of CABG surgery, HRs (95% CI) with empagliflozin vs placebo were 0.52 (0.32, 0.84) for cardiovascular mortality, 0.57 (0.39, 0.83) for all-cause mortality, 0.50 (0.32, 0.77) for hospitalisation for heart failure and 0.65 (0.50, 0.84) for incident or worsening nephropathy. Results were consistent between participants with and without a history of CABG surgery (p > 0.05 for treatment by subgroup interactions).Conclusions/interpretationIn participants with type 2 diabetes and a self-reported history of CABG surgery, treatment with empagliflozin was associated with profound reductions in cardiovascular and all-cause mortality, hospitalisation for heart failure, and incident or worsening nephropathy. These data have important implications for the secondary prevention of cardiovascular events after CABG in individuals with type 2 diabetes.Trial registration:ClinicalTrials.gov NCT01131676Electronic supplementary materialThe online version of this article (10.1007/s00125-018-4644-9) contains peer-reviewed but unedited supplementary material, which is available to authorised users.

“…The capacity of the heart to use fatty acids is reduced in patients with HF, leading to an increased dependence on ketone bodies as an alternative energy source . In patients with T2D and HF, who have low energy reserves and restricted fuel availability, ketone bodies can provide energy more efficiently than glucose or fatty acids, and thereby act as a “super fuel” (Figure ) …”

Effects of sodium‐glucose cotransporter‐2 inhibitors on the cardiovascular and renal complications of type 2 diabetes

Sodium‐glucose cotransporter‐2 inhibitors (SGLT‐2is) have been shown to mitigate the risks of cardiovascular (CV) and renal complications in patients with type 2 diabetes (T2D) and CV risk factors or CV disease (CVD). In CV outcomes trials (CVOTs) of patients with T2D and established CVD or multiple CV risk factors, empagliflozin and canagliflozin were associated with significant reductions in the risks of major adverse CV events (MACE), hospitalization for heart failure (HF) and kidney disease progression. In the DECLARE–TIMI 58 study, in which the majority of patients did not have established CVD, dapagliflozin was associated with significant reductions in the composite end point of CV death or hospitalization for HF and was noninferior to placebo with regard to MACE; although patients had relatively good renal function, dapagliflozin also showed renal benefits similar to those seen with empagliflozin and canagliflozin. This article reviews the increased risk of CVD and renal disease in patients with T2D and discusses the potential mechanisms of the cardioprotective and renoprotective effects of SGLT‐2i therapy. The observed improvements in CV and renal outcomes with SGLT‐2is in CVOTs suggest a class effect in this patient population and have influenced treatment guidelines for the way add‐on therapy to metformin is initiated in patients with T2D and high CV risk. The overall cardioprotective and renoprotective effects of SGLT‐2is in patients with T2D and high CV risk are most likely attributable to multiple mechanisms, including cardiac, haemodynamic, metabolic, anti‐inflammatory and renal effects.

“…The CV benefits attributable to SGLT2 inhibitors could involve several mechanisms, partly related to the glucose‐lowering mechanism, but mostly unrelated to the extent of glucose‐lowering . The glucosuric effect of SGLT2 inhibitors is independent of insulin, but the reduction in glucotoxicity has been shown to reduce insulin resistance and improve β‐cell responsiveness, the former effect being a potential contributor to reduced CV risk .…”

This review examines recent randomized controlled cardiovascular (CV) outcome trials of glucose-lowering therapies in type 2 diabetes and their impact on the treatment of patients with type 2 diabetes. The trials were designed to comply with regulatory requirements to confirm that major adverse cardiac events (MACE) are not detrimentally affected by such therapies. Trials involving dipeptidyl peptidase-4 (DPP-4) inhibitors did not alter a composite MACE outcome comprising CV deaths, non-fatal myocardial infarction and non-fatal stroke; however, the possibility that some members of this class might incur a small increased risk or worsening of heart failure cannot be excluded. Some studies on glucagon-like peptide-1 receptor agonists (liraglutide: LEADER trial; semaglutide: SUSTAIN-6 trial) found significant benefits for MACE, while treatment with sodium-glucose co-transporter-2 inhibitors (empagliflozin: EMPA-REG OUTCOME trial; canagliflozin: CANVAS trial) also significantly reduced MACE and reduced hospitalization for heart failure. Comparisons among trials are complicated by variance in the populations recruited, particularly CV status at randomization, and differences in trial design, data collection and analyses. A large proportion of patients recruited into these trials have previously experienced adverse CV events; thus, the therapies are mostly assessing secondary prevention of a further event. This contrasts with the overall type 2 diabetes population receiving glucose-lowering therapies, of whom the majority will not have had MACE and will be regarded as primary prevention. Overall, the trials provide reassuring evidence that new glucose-lowering medications do not adversely affect CV events and some of these agents may offer CV protection.
