Background: In patients with type 2 diabetes mellitus (T2DM), a history of an ischemic event is associated with increased risk for cardiovascular (CV) disease. Whether patients with T2DM and a recent atherothrombotic diagnosis benefit from early intervention with a sodium-glucose co-transporter 2 inhibitor is unknown.

Methods: This study is a secondary analysis of the gliflozin Cardiovascular Event Trial in Type 2 Diabetes Mellitus Patients-emoving xcess lucose (EMPA-REG OUTCOME), which compared empagliflozin to placebo in adults with T2DM and atherosclerotic CV disease (ASCVD).

We studied journal articles published by researchers at all eight New Zealand universities in 2017 to determine how many were freely accessible on the web. We wrote software code to harvest data from multiple sources, code that we now share to enable others to reproduce our work on their own sample set. In May 2019, we ran our code to determine which of the 2017 articles were open at that time and by what method; where those articles would have incurred an Article Processing Charge (APC) we calculated the cost if those charges had been paid.

Aims: Loop diuretics (LD) relieve symptoms and signs of congestion due to heart failure (HF), but many patients prescribed LD do not have such a diagnosis. We studied the relationship between HF diagnosis, use of LD, and outcomes in patients with type 2 diabetes mellitus (T2DM) enrolled in the EMPA-REG OUTCOME trial.

Methods And Results: The relationship between HF diagnosis, use of LD, and outcomes was evaluated in four patient subgroups with T2DM: (i) investigator-reported HF on LD, (ii) investigator-reported HF not on LD, (iii) no HF on LD, and (iv) no HF and not on LD, and we assessed their risk of cardiovascular events.

Article Synopsis
  • Patients with type 2 diabetes (T2D) and metabolic syndrome (MetS) face higher cardiovascular risks compared to those without MetS, prompting an analysis of empagliflozin's effects on cardio-renal outcomes in the EMPA-REG OUTCOME trial.
  • A study involving 7020 T2D patients revealed that 82% had MetS, which correlated with worse health indicators and higher risks for cardiovascular complications like heart failure and nephropathy in the placebo group.
  • Empagliflozin significantly improved cardio-renal health in both patients with MetS and those without, highlighting its potential benefits across different patient profiles.

Aims: The EMPA-REG OUTCOME trial demonstrated reductions in cardiovascular (CV) death and heart failure (HF) outcomes with empagliflozin, a sodium-glucose co-transporter 2 inhibitor, in patients with type 2 diabetes and established CV disease over a study period of 3 years. We aimed to investigate the early benefit-risk profile of empagliflozin in patients enrolled in the EMPA-REG OUTCOME trial according to HF status at baseline.

Methods And Results: The effects of treatments on glycated haemoglobin, systolic blood pressure and body weight, and on the HF endpoints of hospitalization for HF (HHF), HHF or CV death, and HHF or all-cause mortality were evaluated at 12 weeks, 6 months, and 1 year after randomization.

Background: The sodium-glucose co-transporter 2 (SGLT2) inhibitor empagliflozin reduced cardiovascular death or heart failure hospitalizations in type 2 diabetes (T2D) in addition to a reduction of SBP. As heart failure patients often present with low SBP, which can challenge treatment initiation, we explored if empagliflozin's effect on SBP was independent of baseline SBP and heart failure status, and if the effect on cardiovascular and heart failure outcomes was influenced by updated mean SBP or by an early change in SBP after drug initiation.

Methods And Results: A total of 7020 patients were treated with empagliflozin 10 mg, 25 mg or placebo and followed for a median of 3.

Background: In our 2015 systematic review and meta-analysis of cardiovascular outcome trials for glucose-lowering drugs or strategies in people with or at risk of type 2 diabetes, we reported a modest reduction in atherosclerotic cardiovascular events and an increased risk of heart failure, but with heterogeneous effects by drug or intervention type. In view of the completion of many large cardiovascular outcome trials since our previous analysis, including trials of novel drugs that have shown beneficial effects on cardiovascular outcomes, we aimed to update our analysis to incorporate these findings.

Methods: We did an updated systematic review and meta-analysis of large cardiovascular outcome trials of glucose-lowering drugs or strategies in people with or at risk of type 2 diabetes.
