This EMPEROR-Preserved subanalysis showed that empagliflozin improves blood pressure in patients with resistant hypertension and HFpEF, providing additional hemodynamic benefit in this difficult-to-treat overlap population.
A total of 5533 patients were studied and the population was separated into resistant (resHTN), uncontrolled (uctrHTN), and controlled (ctrHTN) hypertension. The effect of SBP on outcomes and treatment effects of empagliflozin were explored. Analyses were done with Cox regression analyses adjusted for demographic and clinical confounders and with a mixed model for repeated measures.
Empagliflozin reduced SBP in resHTN slightly more than in the other categories in the first weeks, while thereafter there were no significant differences. The modest reduction in SBP resulted in a moderate increase in time at target and reduced hypertensive urgencies. The primary endpoint was more prevalent in resHTN (P = .0358), but the treatment effect of empagliflozin on the primary endpoint was similar in resHTN, uctrHTN, and ctrHTN (P for interaction = .92) as was the improvement of the estimated glomerular filtration rate slope (P for interaction = .95) and change in quality of life by empagliflozin.
In HFpEF, the prevalence of resHTN is high and is associated with frequently higher outcome rates compared with ctrHTN and uctrHTN. The treatment effect was not modified by hypertension categories. This indicates that in HFpEF, moderate modifications of blood pressure do not affect overall outcomes and treatment effects of empagliflozin.
