  • Effect of empagliflozin on exercise ability and symptoms in heart failure patients with reduced and preserved ejection fraction, with and without type 2 diabetes.

    • The EMPERIAL (Effect of EMPagliflozin on ExeRcise ability and HF symptoms In patients with chronic heArt faiLure) trials evaluated the effects of empagliflozin on exercise ability and patient-reported outcomes in heart failure (HF) with reduced and preserved ejection fraction (EF), with and without type 2 diabetes (T2D), reporting, for the first time, the effects of sodium-glucose co-transporter-2 inhibition in HF with preserved EF (HFpEF).HF patients with reduced EF (HFrEF) (≤40%,N = 312, EMPERIAL-Reduced) or preserved EF (>40%,N = 315, EMPERIAL-Preserved), with and without T2D, were randomized to empagliflozin 10 mg or placebo for 12 weeks. The primary endpoint was 6-minute walk test distance (6MWTD) change to Week 12. Key secondary endpoints included Kansas City Cardiomyopathy Questionnaire Total Symptom Score (KCCQ-TSS) and Chronic Heart Failure Questionnaire Self-Administered Standardized format (CHQ-SAS) dyspnoea score. 6MWTD median (95% confidence interval) differences, empagliflozin vs. placebo, at Week 12 were -4.0 m (-16.0, 6.0;P = 0.42) and 4.0 m (-5.0, 13.0;P = 0.37) in EMPERIAL-Reduced and EMPERIAL-Preserved, respectively. As the primary endpoint was non-significant, all secondary endpoints were considered exploratory. Changes in KCCQ-TSS and CHQ-SAS dyspnoea score were non-significant. Improvements with empagliflozin in exploratory pre-specified analyses of KCCQ-TSS responder rates, congestion score, and diuretic use in EMPERIAL-Reduced are hypothesis generating. Empagliflozin adverse events were consistent with those previously reported.The primary outcome for both trials was neutral. Empagliflozin was well tolerated in HF patients, with and without T2D, with a safety profile consistent with that previously reported in T2D. Hypothesis-generating improvements in exploratory analyses of secondary endpoints with empagliflozin in HFrEF were observed.

  • Sex-Specific Outcomes of Transcatheter Mitral-Valve Repair and Medical Therapy for Mitral Regurgitation in Heart Failure.
  • 2021
  • Ingår i: JACC. Heart failure. - 2213-1787.
  • Tidskriftsartikel (refereegranskat)abstract
    • This study sought to assess the sex-specific outcomes in patients with heart failure (HF) with 3+ and 4+ secondary mitral regurgitation (SMR) treated with transcatheter mitral valve repair (TMVr) plus guideline-directed medical therapy (GDMT) versus GDMT alone in the COAPT trial.The impact of sex in patients with HF and severe SMR treated with TMVr with the MitraClip compared with GDMT alone is unknown.Patients were randomized 1:1 to TMVr versus GDMT alone. Two-year outcomes were examined according to sex.Among 614 patients, 221 (36.0%) were women. Women were younger than men and had fewer comorbidities, but reduced quality of life and functional capacity at baseline. In a joint frailty model accounting for the competing risk of death, the 2-year cumulative incidence of the primary endpoint of all HF hospitalizations (HFH) was higher in men compared with women treated with GDMT alone. However, the relative reduction in HFHs with TMVr was greater in men (HR: 0.43; 95% CI: 0.34-0.54) than women (HR: 0.78; 95% CI: 0.57-1.05) (Pinteraction = 0.002). A significant interaction between TMVr versus GDMT alone treatment and time was present for all HFHs in women (HR: 0.57; 95% CI: 0.39-0.84, and HR: 1.39; 95% CI: 0.83-2.33 between 0-1 year and 1-2 years after randomization, respectively, Pinteraction = 0.007) but not in men (HR: 0.48; 95% CI: 0.36-0.64, and HR: 0.33; 95% CI: 0.21-0.51; Pinteraction = 0.16). Female sex was independently associated with a lower adjusted risk of death at 2 years (HR: 0.64; 95% CI: 0.46-0.90; P = 0.011). TMVr consistently reduced 2-year mortality compared with GDMT alone, irrespective of sex (Pinteraction = 0.99).In the COAPT trial, TMVr with the MitraClip resulted in improved clinical outcomes compared with GDMT alone, irrespective of sex. However, the impact of TMVr in reducing HFH was less pronounced in women compared with men beyond the first year after treatment.

  • Prediction of Death or HF Hospitalization in Patients With Severe FMR: The COAPT Risk Score.
  • 2022
  • Ingår i: JACC. Cardiovascular interventions. - 1876-7605. ; 15:19, s. 1893-1905
  • Tidskriftsartikel (refereegranskat)abstract
    • There are limited data on the predictors of death or heart failure hospitalization (HFH) in patients with heart failure (HF) with functional mitral regurgitation (FMR).The aim of this study was to develop a predictive risk score using the COAPT (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients With Functional Mitral Regurgitation) trial database.In COAPT, 614 symptomatic patients with HF and moderate to severe or severe FMR were randomized to MitraClip implantation plus guideline-directed medical therapy (GDMT) or GDMT alone. A risk score for the 2-year rate of death or HFH was generated from Cox proportional hazards models. The predictive value of the model was assessed using the area under the curve of receiver-operating characteristic plots. Kaplan-Meier curves were generated to estimate the proportion of patients experiencing death or HFH across quartiles of risk.During 2-year follow-up, 201 patients (64.4%) in the GDMT-alone group and 133 patients (44.0%) in the MitraClip group experienced death or HFH (P < 0.001). A risk score containing 4 clinical variables (New York Heart Association functional class, chronic obstructive pulmonary disease, atrial fibrillation or flutter, and chronic kidney disease) and 4 echocardiographic variables (left ventricular ejection fraction, left ventricular end-systolic dimension, right ventricular systolic pressure, and tricuspid regurgitation) in addition to MitraClip treatment was generated. The area under the curve of the risk score model was 0.74, and excellent calibration was present. The relative benefit of MitraClip therapy in reducing the 2-year hazard of death or HFH was consistent across the range of baseline risk.A simple risk score of clinical, echocardiographic, and treatment variables may provide useful prognostication in patients with HF and severe FMR.
