Insights
Guideline-directed medication therapy (GDMT) for heart failure with reduced ejection fraction (HFrEF) did not significantly alter outcomes in end-stage renal disease (ESRD) patients. However, GDMT was associated with less hypotension, suggesting potential benefits for this population.
Area of Science:
- Cardiology
- Nephrology
- Clinical Pharmacology
Background:
- Guideline-directed medication therapy (GDMT) is crucial for heart failure with reduced ejection fraction (HFrEF).
- Concerns exist regarding underprescription of GDMT in end-stage renal disease (ESRD) patients.
- This study investigates GDMT's impact on HFrEF patients with ESRD.
Purpose of the Study:
- To compare outcomes for ESRD patients with HFrEF receiving GDMT versus those not receiving it.
- To evaluate the effect of GDMT on length of stay, mortality, and readmissions in this cohort.
- To assess the incidence of adverse events like hyperkalemia, hypotension, and bradycardia with GDMT use.
Main Methods:
- Retrospective analysis of adult ESRD and HFrEF patients admitted over two years.
- Categorization into GDMT and non-GDMT groups based on home medication regimens.
- Comparison of length of stay, mortality, 30-day readmissions, and adverse events between groups.
Main Results:
- A total of 109 patients were included; 25 received GDMT and 84 did not.
- No significant differences in length of stay, 30-day readmissions, or in-hospital mortality between groups.
- Hypotension occurred significantly less frequently in the GDMT group (4% vs. 27%, P = 0.01).
Conclusions:
- GDMT did not significantly impact primary outcomes (LOS, mortality, readmissions) in ESRD patients with HFrEF.
- The reduced incidence of hypotension in the GDMT group may hold clinical significance.
- A substantial proportion of ESRD patients with HFrEF are not receiving GDMT, warranting further investigation.
Background:
Treatment of heart failure with reduced ejection fraction (HFrEF) requires guideline-directed medication therapy (GDMT) consisting of either an angiotensin-converting enzyme inhibitor or an angiotensin receptor blocker in combination with an indicated beta-blocker. There is concern that end-stage renal disease (ESRD) patients are not being prescribed GDMT. The study aim was to determine whether outcomes differ for patients with HFrEF and ESRD receiving GDMT compared to those not receiving GDMT.
Materials And Methods:
Adult patients with ESRD and HFrEF admitted to a tertiary teaching hospital over a 2-year period were included. Patients were categorized into GDMT or non-GDMT groups based on their home medications. The length of stay (LOS), mortality, and 30-day hospital readmissions were compared between groups. The incidence of hyperkalemia, hypotension and bradycardia were also evaluated.
Results:
A total of 109 patients were included: 88% African-American, 61% males, median age 63 (28-93) years with 25 in the GDMT group and 84 in the non-GDMT group. The LOS did not differ between the GDMT (5 days; 3-14) compared to the non-GDMT group (7 days; 3-28), P = 0.14. Thirty-day hospital readmission and in-hospital mortality were also similar. Hypotension occurred less frequently in the GDMT group compared to the non-GDMT group, 4% versus 27% (P = 0.01).
Conclusions:
Although there were no differences in the primary outcomes, the shorter LOS in the GDMT group may be clinically significant. The fact that most patients with ESRD and HFrEF were not receiving GDMT is a finding that requires further evaluation.

Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
