Empagliflozin and hydralazine-isosorbide dinitrate combination therapy improves outcomes in Black patients with heart failure.

BACKGROUND

Black patients experience a disproportionately high incidence of heart failure with reduced ejection fraction (HFrEF), where vasodilators serve as a key therapeutic strategy.

MATERIALS AND

METHODS

A retrospective cohort study based on medical records of Black patients with HFrEF and an ex vivo analysis of mouse thoracic aorta stimulated with empagliflozin (empa) and hydralazine-isosorbide dinitrate (H-ISDN).

RESULTS

The combination synergistically activated cyclic guanosine monophosphate (cGMP) production in the ex vivo thoracic aorta and improved kidney function, reduced brain natriuretic peptide (BNP), and lowered mortality compared to H-ISDN alone in HFrEF patients.

CONCLUSION

Empa + H-ISDN offered superior benefits in Black patients with HFrEF, possibly by reducing oxidative stress and enhancing nitric oxide (NO) bioavailability.
