Effect of sacubitril/valsartan versus enalapril on glycaemic control in patients with heart failure and diabetes: a post-hoc analysis from the PARADIGM-HF trial.

Diabetes is an independent risk factor for heart failure progression. Sacubitril/valsartan, a combination angiotensin receptor-neprilysin inhibitor, improves morbidity and mortality in patients with heart failure with reduced ejection fraction (HFrEF), compared with the angiotensin-converting enzyme inhibitor enalapril, and improves peripheral insulin sensitivity in obese hypertensive patients. We aimed to investigate the effect of sacubitril/valsartan versus enalapril on HbA1c and time to first-time initiation of insulin or oral antihyperglycaemic drugs in patients with diabetes and HFrEF. In a post-hoc analysis of the PARADIGM-HF trial, we included 3778 patients with known diabetes or an HbA1c ≥6·5% at screening out of 8399 patients with HFrEF who were randomly assigned to treatment with sacubitril/valsartan or enalapril. Of these patients, most (98%) had type 2 diabetes. We assessed changes in HbA1c, triglycerides, HDL cholesterol and BMI in a mixed effects longitudinal analysis model. Time to initiation of oral antihyperglycaemic drugs or insulin in subjects previously not treated with these agents were compared between treatment groups. There were no significant differences in HbA1c concentrations between randomised groups at screening. During the first year of follow-up, HbA1c concentrations decreased by 0·16% (SD 1·40) in the enalapril group and 0·26% (SD 1·25) in the sacubitril/valsartan group (between-group reduction 0·13%, 95% CI 0·05-0·22, p=0·0023). HbA1c concentrations were persistently lower in the sacubitril/valsartan group than in the enalapril group over the 3-year follow-up (between-group reduction 0·14%, 95% CI 0·06-0·23, p=0·0055). New use of insulin was 29% lower in patients receiving sacubitril/valsartan (114 [7%] patients) compared with patients receiving enalapril (153 [10%]; hazard ratio 0·71, 95% CI 0·56-0·90, p=0·0052). Similarly, fewer patients were started on oral antihyperglycaemic therapy (0·77, 0·58-1·02, p=0·073) in the sacubitril/valsartan group. Patients with diabetes and HFrEF enrolled in PARADIGM-HF who received sacubitril/valsartan had a greater long-term reduction in HbA1c than those receiving enalapril. These data suggest that sacubitril/valsartan might enhance glycaemic control in patients with diabetes and HFrEF. Novartis.

Health-Related Quality of Life Outcomes in PARADIGM-HF.

Patients with heart failure and reduced ejection fraction have impaired health-related quality of life (HRQL) with variable responses to therapies that target mortality and heart failure hospitalizations. In PARADIGM-HF trial (Prospective Comparison of ARNI [Angiotensin Receptor-Neprilysin Inhibitor] With ACEI [Angiotensin-Converting-Enzyme Inhibitor] to Determine Impact on Global Mortality and Morbidity in Heart Failure), sacubitril/valsartan reduced morbidity and mortality compared with enalapril. Another major treatment goal is to improve HRQL. Given improvements in mortality with sacubitril/valsartan, this analysis provides comprehensive assessment of impact of therapy on HRQL in survivors only. Patients (after run-in phase) completed disease-specific HRQL using Kansas City Cardiomyopathy Questionnaire (KCCQ) at randomization, 4 month, 8 month, and annual visits. Changes in KCCQ scores were calculated using repeated measures analysis of covariance model that adjusted for treatment and baseline values (principal efficacy prespecified at 8 months). Among the 8399 patients enrolled in PARADIGM-HF, 7623 (91%) completed KCCQ scores at randomization with complete data at 8 months for 6881 patients (90% of baseline). At 8 months, sacubitril/valsartan group noted improvements in both KCCQ clinical summary score (+0.64 versus -0.29; P=0.008) and KCCQ overall summary score (+1.13 versus -0.14; P<0.001) in comparison to enalapril group and significantly less proportion of patients with deterioration (≥5 points decrease) of both KCCQ scores (27% versus 31%; P=0.01). Adjusted change scores demonstrated consistent improvements in sacubitril/valsartan compared with enalapril through 36 months. Change scores in KCCQ clinical summary scores and KCCQ overall summary scores were better in patients treated with sacubitril/valsartan compared with those treated with enalapril, with consistency in most domains, and persist during follow-up beyond 8 months. These findings demonstrate that sacubitril/valsartan leads to better HRQL in surviving patients with heart failure. URL: http://www.clinicaltrials.gov. Unique identifier: NCT01035255.

Influence of Ejection Fraction on Outcomes and Efficacy of Sacubitril/Valsartan (LCZ696) in Heart Failure with Reduced Ejection Fraction: The Prospective Comparison of ARNI with ACEI to Determine Impact on Global Mortality and Morbidity in Heart Failure (

The angiotensin receptor neprilysin inhibitor sacubitril/valsartan (LCZ696) reduced cardiovascular morbidity and mortality compared with enalapril in patients with heart failure (HF) and reduced ejection fraction (EF) in the Prospective Comparison of ARNI with ACEI to Determine Impact on Global Mortality and Morbidity in Heart Failure (PARADIGM-HF) trial. We evaluated the influence of EF on clinical outcomes and on the effectiveness of sacubitril/valsartan compared with enalapril. Eight thousand three hundred ninety-nine patients with New York Heart Association class II to IV HF with reduced EF [left ventricular EF (LVEF) ≤40%] were randomized to sacubitril/valsartan 97/103 mg twice daily versus enalapril 10 mg twice daily and followed for a median of 27 months. The primary study end point was cardiovascular death or HF hospitalization. LVEF was assessed at the sites and recorded on case report forms. We related LVEF to study outcomes and assessed the effectiveness of sacubitril/valsartan across the LVEF spectrum. The mean LVEF in PARADIGM-HF, reported by sites, was 29.5 (interquartile range, 25-34). The risk of all outcomes increased with decreasing LVEF. Each 5-point reduction in LVEF was associated with a 9% increased risk of cardiovascular death or HF hospitalization (hazard ratio, 1.09; 95% confidence interval, 1.05-1.13; P<0.001), a 9% increased risk for CV death (hazard ratio, 1.09; 95% confidence interval, 1.04-1.14), a 9% increased risk in HF hospitalization (hazard ratio, 1.09; 95% confidence interval, 1.04-1.14) and a 7% increased risk in all-cause mortality (hazard ratio, 1.07; 95% confidence interval, 1.03-1.12) in adjusted analyses. Sacubitril/valsartan was effective across the LVEF spectrum, with no evidence of heterogeneity, when modeled either in tertiles (P interaction=0.87) or continuously (P interaction=0.95). In patients with HF and reduced EF enrolled in PARADIGM-HF, LVEF was a significant and independent predictor of all outcomes. Sacubitril/valsartan was effective at reducing cardiovascular death and HF hospitalization throughout the LVEF spectrum. URL: http://www.clinicaltrials.gov. Unique identifier: NCT01035255.
