Background: Post hoc analysis of the PARADIGM-HF trial showed that sacubitril/valsartan (S/V) was more effective than enalapril in lowering HbA1c in patients with heart failure and diabetes.
Methods and Results: In the present study, the effect of S/V on glycemic control was retrospectively analyzed in 150 patients (median age 74 years) who were prescribed S/V for the treatment of heart failure and/or hypertension. After a median period of 13 weeks treatment, mean (±SD) HbA1c levels decreased significantly from 6.56±0.68% to 6.49±0.63%. The decrease in HbA1c was evident in patients with (n=111), but not in those without, diabetes. There were no significant changes in renal function after S/V treatment, but systolic blood pressure was significantly reduced from 141±21 to 134±19 mmHg. Ninety patients had N-terminal pro B-type natriuretic peptide (NT-proBNP) tested, and S/V significantly decreased median NT-proBNP concentrations from 1,026 to 618 pg/mL; however, there was no correlation between the degree of decrease in HbA1c and that in NT-proBNP. Multiple regression analysis revealed that being diabetic, rather than having heart failure, was a significant independent variable for a reduction in HbA1c.
Conclusions: Treatment with S/V improved glycemic control in patients with heart failure and/or hypertension, especially in those with concomitant diabetes. This favorable effect on glucose metabolism may be mediated by neprilysin inhibition and is desirable in the treatment of heart failure and hypertension in diabetic patients.
