Heart failure & cardiomyopathiesSecondary analysis

Guideline-directed Medical Therapy (GDMT) is Associated with Reduced Loop Diuretic Requirements, Whereas Diuretic Dose Does Not Modify GDMT Benefit in Heart Failure: STRONG-HF.

Eur J Heart FailPublished

  • post-hoc analysis of STRONG-HF

Authors' conclusion

GDMT optimization acted as diuretic-sparing therapy: reaching target doses, particularly of all three classes, was associated with markedly lower LD requirement. LD dose mirrored HF severity but neither consistently predicted outcome nor modified the benefit of up-titration.

Study context

Population
Patients with heart failure in STRONG-HF with post-randomization loop diuretic datawith post-randomization loop diuretics (LD) data
Participants
1,075 patients
Comparison
change at day 90 was compared by achievement of 100% target GDMT doses
Primary endpoint
all-cause death or HF rehospitalization
Follow-up
180 days

Primary result

As reported in the abstract

  • LD dose category was not independently associated with the primary endpoint or its components

Higher LD doses marked more severe HF

Benefit of high-intensity care across LD dose groups

consistent across LD dose groups (no treatment-by-dose interaction)
