Insights
Adherence to guideline-directed medical therapy (GDMT) for heart failure in older adults is low. Physicians must individualize treatment, balancing guidelines with patient-specific factors like life expectancy and care goals.
Area of Science:
- Cardiology
- Geriatrics
- Pharmacology
Background:
- Heart failure is a major cause of hospitalization in older adults.
- Guideline-directed medical therapy (GDMT) improves outcomes but is difficult to implement in this population.
- The 2021 ESC heart failure guideline provides recommendations for managing heart failure.
Purpose of the Study:
- To evaluate adherence to the 2021 ESC heart failure guideline in older patients (70+ years).
- To explore reasons for deviations from GDMT in this demographic.
- To analyze factors associated with GDMT non-adherence.
Main Methods:
- Retrospective cohort study of 60 patients (≥70 years) with decompensated heart failure (ejection fraction <50%).
- Data collected at discharge and 3 months post-discharge on GDMT use, dosage, and reasons for deviations.
- Analysis of associations between GDMT adherence and age, frailty, comorbidities, and admission specialty.
Main Results:
- Only 15% of patients received all four GDMT drugs at discharge, increasing to 26% at follow-up; only 3% achieved target doses.
- Older patients (>80 years) received GDMT less frequently at discharge (4% vs. 26%, p=0.03), though this normalized at follow-up.
- Common reasons for non-adherence included adverse effects, contraindications, reduced life expectancy, and treatment postponement.
Conclusions:
- Adherence to GDMT in older heart failure patients is suboptimal.
- Physicians need to carefully weigh guideline recommendations against individual patient factors, including life expectancy and personal care objectives.
- Individualized care is crucial for optimizing heart failure management in the elderly.
Abstract:
Objectives: Heart failure is one of the leading causes of hospitalization in older adults. Guideline-directed medical therapy (GDMT) reduces the risk of decompensation and hospitalization, though it is challenging to implement GDMT in this group. Therefore, this study evaluated adherence to the 2021 ESC heart failure guideline in older patients and explored reasons for guideline deviations. Methods: A retrospective cohort study was performed in older patients (70+ years) with decompensated heart failure (ejection fraction < 50%) admitted to the cardiology or geriatrics department at a tertiary hospital (May 2022-September 2023). Data on GDMT-drug use, dosage, and reasons for guideline deviations were collected at discharge and three months post-discharge. Additionally, associations between GDMT non-adherence and factors such as age, frailty, comorbidities, and admission specialty were analyzed. Results: A total of 60 patients were included (mean age 79 years, 40% women, median EF 34%). The four GDMT drugs were prescribed to 15% of patients at discharge and 26% at follow-up, and 3% of the patients received the target dose for all drugs. Older patients (>80 years) received GDMT less frequently at discharge compared to younger patients (4% vs. 26%, p = 0.03). Though this difference was resolved at follow-up. The other studied factors were not significantly associated with GDMT adherence. Common reasons for guideline deviations were adverse effects, contraindications, reduced life expectancy, and postponed treatment. Conclusions: Adherence to GDMT in older heart failure patients is low due to several reasons, such as relevant contraindications. Physicians should carefully balance the risks and benefits of the guideline versus individual benefit, considering life expectancy and individual care goals.
