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).
Article Synopsis
- Empagliflozin is known to improve cardiovascular outcomes in various patient groups, but its safety and effectiveness in those who have experienced an acute myocardial infarction were previously unclear.
- In a study involving 6522 patients at risk for heart failure after a heart attack, participants were given either empagliflozin or a placebo, with their health monitored over about 18 months.
- The results showed that empagliflozin did not significantly reduce the risk of hospitalization for heart failure or death compared to placebo, though it did show some potential benefits regarding hospitalizations specifically for heart failure.
Article Synopsis
- * In the EMPACT-MI trial, 6,522 patients were randomly assigned to receive either empagliflozin or placebo, with the results showing a significant difference in HF events after a median follow-up of 17.9 months.
- * The study also noted that patients taking empagliflozin required fewer additional heart failure medications after discharge, indicating a broader benefit in managing heart failure risks.
Aims: Empagliflozin has been shown to reduce the risk of adverse cardiovascular outcomes in patients with type 2 diabetes and in those with heart failure. The impact of empagliflozin in post-acute myocardial infarction (AMI) patients is unknown.
Methods And Results: The Study to Test the Effect of Empagliflozin on Hospitalization for Heart Failure and Mortality in Patients with Acute Myocardial Infarction (EMPACT-MI) trial screened 6610 participants with AMI and randomized 6522 to empagliflozin or placebo in addition to standard of care.
Background: Patients with acute myocardial infarction (MI) are at risk for developing heart failure (HF) and subsequently are at an increased risk of mortality. Sodium-glucose cotransporter-2 inhibitors have been proven to improve outcomes in patients with HF with reduced ejection fraction, and, in the case of empagliflozin, in HF with preserved ejection fraction even without diabetes, but their efficacy and safety in the post-MI population has not yet been evaluated.
Methods: The EMPACT-MI trial will evaluate the safety and efficacy of empagliflozin compared with placebo in patients hospitalized for MI with or at high risk of new onset HF, in addition to standard care.
Background: In the EMPA-REG OUTCOME trial, ejection fraction (EF) data were not collected. In the subpopulation with heart failure (HF), we applied a new predictive model for EF to determine the effects of empagliflozin in HF with predicted reduced (HFrEF) vs preserved (HFpEF) EF vs no HF.
Methods And Results: We applied a validated EF predictive model based on patient baseline characteristics and treatments to categorize patients with HF as being likely to have HF with mid-range EF (HFmrEF)/HFrEF (EF <50%) or HFpEF (EF ≥50%).
Objectives: Using latent class analysis (LCA) of EMPA-REG OUTCOME (BI 10773 [Empagliflozin] Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients), this study identified distinct phenotypes in subjects with type 2 diabetes (T2D) and cardiovascular (CV) disease and explored treatment effects across phenotypes.
Background: In the EMPA-REG OUTCOME trial, empagliflozin reduced risk of CV death or hospitalization for heart failure (HHF) by 34% in subjects with T2D and CV disease. Among such subjects, there has been limited evaluation of clinical phenotypes.
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.
Aim: To investigate whether the cardiorenal benefits of the sodium-glucose co-transporter-2 inhibitor empagliflozin are affected by body mass index (BMI) in type 2 diabetes patients with established cardiovascular (CV) disease, including Asians.
Methods: In this exploratory analysis of the EMPA-REG OUTCOME trial, we used Cox regression to evaluate the effects of empagliflozin on all-cause mortality, hospitalization for heart failure (HHF) or CV death, and incident or worsening nephropathy by baseline BMI category.
Results: Of the 7020 participants (1517 Asians [21.
Background Cardio/kidney composite end points are clinically relevant but rarely analyzed in cardiovascular trials. This post hoc analysis of the EMPA-REG OUTCOME (Empagliflozin Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients) trial evaluated cardio/kidney composite end points by 2 statistical approaches. Methods and Results A total of 7020 patients with type 2 diabetes mellitus and established cardiovascular disease were treated with empagliflozin 10 or 25 mg (n=4687) or placebo (n=2333) on top of standard care.

Background: Patients with type 2 diabetes (T2D) and metabolic syndrome (MetS) are at greater cardiovascular risk than those with T2D without MetS. In the current report we aim to study the characteristics, cardio-renal outcomes and the effect of empagliflozin in patients with MetS enrolled in the EMPA-REG OUTCOME trial.
Methods: A total of 7020 patients with T2D and atherosclerotic cardiovascular disease were treated with empagliflozin (10 mg or 25 mg) or placebo for a median of 3.
Aim: To investigate the association of different categories of baseline cardio-metabolic risk factors on the treatment effects of empagliflozin 10 and 25 mg when added as second-line therapy to metformin in patients with type 2 diabetes (T2D).
Materials And Methods: Patients aged 18 years or older with HbA1c 7.0%-10.
Background: Glucose variability has been associated with cardiovascular outcomes in type 2 diabetes, however, the interplay between glucose variability, empagliflozin and cardiovascular death has not been explored. In the EMPA-REG OUTCOME trial, empagliflozin reduced the risk of cardiovascular death by 38%. We explore post-hoc the association between HbA1c variability and cardiovascular death, and the potential mediating effects of HbA1c variability on empagliflozin's cardiovascular death reductions.

Research Design And Methods: Participants with diabetes and CV disease were randomized to empagliflozin (10 and 25 mg) or placebo daily in addition to standard of care. OSA was assessed by investigator report using Medical Dictionary for Regulatory Activities version 18.
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.
Introduction: The aim of this analysis was to characterize the safety and tolerability of empagliflozin in patients with type 2 diabetes mellitus (T2DM) who were randomized to empagliflozin (10/25 mg) or placebo in clinical trials.
Methods: Pooled data from 20 trials were analyzed for patients with T2DM treated with empagliflozin 10 mg (n = 4858), empagliflozin 25 mg (n = 5057), or placebo (n = 4904). The dataset comprised 15 randomized phase I-III trials, an extension trial and dose escalation studies.
Background: Type 2 diabetes (T2D) and resistant hypertension often coexist, greatly increasing risk of target-organ damage and death. We explored the effects of empagliflozin in patients with and without presumed resistant hypertension (prHT) in a post hoc analysis of EMPA-REG OUTCOME (NCT01131676).
Methods: Overall, 7,020 patients received empagliflozin 10, 25 mg, or placebo with median follow-up of 3.
Aim: To investigate the association of the Thrombolysis In Myocardial Infarction (TIMI) Risk Score for Heart Failure in Diabetes (TRS-HF ) with mortality using data from the EMPA-REG OUTCOME trial.
Materials And Methods: In EMPA-REG OUTCOME, patients with type 2 diabetes and atherosclerotic cardiovascular (CV) disease (N = 7020) received the sodium-glucose co-transporter-2 inhibitor, empagliflozin, 10 or 25 mg or placebo. Post hoc, patients were stratified into risk categories (low-intermediate, high, very-high risk scores) using baseline TRS-HF .
