NCT07275437

Brief Summary

Guideline-directed medical therapy (GDMT) for heart failure with reduced ejection fraction (HFrEF) constitutes of four medications that substantially reduce morbidity and mortality, and improve quality of life. In routine clinical practice, various physician- and patient-related factors lead to suboptimal initiation and uptitration of GDMT to optimal dosing, which is associated with worse patient outcomes. A perceived major barrier to the optimalization of GDMT are changes in kidney function and electrolytes, which prompts physicians to halt uptitration, reduce doses, or even discontinue GDMT. Changes in kidney function and electrolytes during optimalization of GDMT are common, but not associated with adverse events. The hypothesis of this study is that a reduction in the number of kidney function assessments during initiation and uptitration of GDMT in HFrEF patients will lead to higher achieved doses of GDMT without safety concerns.

Outcome Measures

Primary Outcomes (1)

  • The achieved average percentage dose of reno-active GDMT at 6 months relative to optimal dose.

    6 months

Secondary Outcomes (2)

  • The achieved percentage dose of the individual reno-active GDMT drug classes at 6 months relative to optimal dose.

    6 months

  • The time to first occurrence of unplanned heart failure visit, heart failure hospitalization, or all-cause mortality till 9 months.

    9 months

Other Outcomes (5)

  • The achieved average percentage dose of all GDMT at 6 months relative to optimal dose.

    6 months

  • Percentage change in NT-pro BNP at 6 months

    6 months

  • Percentage change in loop diuretics at 6 months

    6 months

  • +2 more other outcomes

Study Arms (2)

Limited number of kidney function assessments

EXPERIMENTAL

Participants in this arm will have standardized kidney function assessments at baseline, three months, and six months. Kidney function assessments in between these moments will be blinded in the electronic patient dossier. Unblinding will be performed if the results are significantly abnormal.

Other: Blinded kidney function assessments

Control

NO INTERVENTION

Participants will receive standard care, which includes frequent kidney function assessments.

Interventions

Kidney function results will be blinded in the intervention group, except at baseline, three months, and six months.

Limited number of kidney function assessments
