Aims We investigated the associations between obesity, cardiorenal events, and benefits of dapagliflozin in patients with type 2 diabetes mellitus (T2DM). Methods and results DECLARE–TIMI 58 randomized patients with T2DM and either atherosclerotic cardiovascular (CV) disease or multiple risk factors to dapagliflozin vs. placebo. Patients were stratified by body mass index (BMI, kg/m2): normal (18.5 to Conclusions In DECLARE–TIMI 58, patients with T2DM and higher BMI were more likely to have HHF and AF/AFL. Whereas relative risk reductions in CV and renal outcomes with dapagliflozin were generally consistent across the range of BMI, absolute risk reduction in obesity-related outcomes including HHF and AF/AFL tended to be larger in obese patients with T2DM.

Background The impact on outcomes of oral anticoagulants in pts at extremes of body weight have not been well-characterized. Aim To analyse the outcomes of pts with atrial fibrillation (AF) enrolled in ENGAGE AF-TMI 48 randomized to warfarin (W) targeting INR 2.0–3.0, higher (HDE) or lower dose regimens of edoxaban (LDE), focusing on subgroups of patients at the extremes of weight. Methods and results Among 21105 pts enrolled in the trial we identified 3 subgroups: 1082 with low body weight (LBW) (95th percentile, >120 kg). Baseline characteristics differed markedly (LWB pts were older and more likely Asian, women, with prior TIA/stroke, renal dysfunction) resulting in a trend towards higher rates of stroke/systemic embolism (SSE: 6.5% vs 4.7% in MBW vs 1.6% in HBW) and major bleeding (MB: 9.3% vs 7.7% in MBW vs 6.5% in HBW) in the warfarin arm. The risks of SSE (Pint = 0.52) were similar between W and HDE regardless of body weight, while the relative reduction in MB was greatest in LBW patients (HR reduction45%, 23%, 1% across weight groups; Pint = 0.35) (Figure). Net clinical outcomes (SEE/major bleeding/death) tended to be most favourable for LBW pts (HR 0.67 [0.50–0.90]; Pint 0.084) (Figure). Main outcomes during follow up Conclusions In ENGAGE AF-TIMI 48 the profile of AF pts with LBW markedly differed suggesting a more fragile clinical status. Use of dose-adjusted edoxaban, as compared to W, was associated with similar efficacy regardless of weight, while bleeding and net outcomes were most favourable in LBW pts.

Aims To investigate the relationship between body mass index (BMI) and outcomes in patients with atrial fibrillation (AF). Methods and results In the ENGAGE AF-TIMI 48 trial, patients with AF were randomized to warfarin (international normalized ratio 2.0–3.0) or edoxaban. The cohort (N = 21 028) included patients across BMI categories (kg/m2): underweight (18.5 kg/m2, while time in therapeutic range for warfarin improved significantly as BMI increased (P Conclusion An increased BMI was independently associated with a lower risk of stroke/SEE, better survival, but increased risk of bleeding. The efficacy and safety profiles of edoxaban were similar across BMI categories ranging from 18.5 to >40.

Aims We evaluated the relationship of renal function and ischaemic and bleeding risk as well as the efficacy and safety of ticagrelor in stable patients with prior myocardial infarction (MI). Methods and results Patients with a history of MI 1–3 years prior from PEGASUS-TIMI 54 were stratified based on estimated glomerular filtration rate (eGFR), with
