Dr. Michelle Kittleson, a heart failure expert and professor at Cedars-Sinai, discusses the complexities of heart failure with preserved ejection fraction (HFpEF). She breaks down the challenges of diagnosing this condition and introduces the H2F-PEF score for assessment. The conversation covers managing comorbidities, the positive impact of weight loss and exercise, and highlights promising results from GLP-1 receptor agonists. Kittleson emphasizes the importance of recognizing unique patient needs and adjusting treatment strategies accordingly.
HFPEF diagnosis relies heavily on comprehensive assessments and differentiating it from similar conditions like liver or kidney disease.
Management of HFPEF should focus on treating comorbidities alongside guideline-directed medical therapy, including SGLT2 inhibitors and lifestyle modifications.
Emerging research is exploring newer treatment options like GLP-1 receptor agonists, showing promise for improved outcomes in HFPEF management.

Introduction to Heart Failure with Preserved Ejection Fraction
Heart failure with preserved ejection fraction (HFPEF) presents unique challenges in diagnosis and treatment, primarily characterized by symptoms of dyspnea and edema in patients whose ejection fraction remains normal or above 50%. Unlike heart failure with reduced ejection fraction, where clear diagnostic criteria exist, HFPEF requires comprehensive assessments to determine the underlying cause of the symptoms. A thorough history and physical examination are essential to differentiate HFPEF from other potential causes, including liver or kidney conditions that can mimic heart failure. The complexity of HFPEF stems from its multifactorial nature, necessitating a careful evaluation of various contributing factors, including patient demographics and coexisting conditions.
Diagnosing HFPEF: Challenges and Considerations
The diagnosis of HFPEF often involves understanding various differential diagnoses, as multiple conditions can lead to symptoms of dyspnea and edema. The initial approach begins with clinical evaluation, focusing on identifying whether the heart is indeed the source of symptoms. Key aspects to assess include evaluating for conditions like cirrhosis, kidney disease, or venous insufficiency, which might present similarly to HFPEF. Ultimately, an echocardiogram serves as a valuable tool, providing insight into the heart's function and aiding clinicians in confirming the diagnosis and ruling out secondary causes.
Management Strategies for HFPEF
Management of HFPEF encompasses addressing the patient's overall health, emphasizing the importance of treating comorbidities, and utilizing guideline-directed medical therapy. SGLT2 inhibitors have emerged as a primary treatment option, showing significant benefits in reducing both heart failure-related hospitalizations and mortality. Additionally, mineralocorticoid receptor antagonists may be beneficial, particularly for patients experiencing congestion or hypertension. Beyond pharmacological interventions, lifestyle changes such as diet management and physical activity, specifically tailored cardiac rehabilitation programs, play an important role in enhancing patient outcomes and quality of life.
The Role of Comorbidities in HFPEF
HFPEF often occurs alongside a range of comorbid conditions, such as obesity, hypertension, and diabetes, which significantly influence patient outcomes. Effective management entails identifying and treating these comorbidities concurrently, as they can exacerbate heart failure symptoms and complicate treatment strategies. Notably, patients may present with various phenotypes, leading to distinct pathways of treatment that need to be personalized. Integration of multidisciplinary approaches can assist in optimizing care for these patients, as addressing comorbid conditions often yields improvements in overall heart failure management.
Emerging Evidence and Future Directions
Current research continues to explore the intricacies of HFPEF, focusing on identifying effective treatment modalities aimed at this heterogeneous condition. While traditional medications have occasionally shown limited efficacy, newer options such as GLP-1 receptor agonists are gaining attention for their potential benefits in weight management and cardiovascular outcomes. Ongoing trials are essential to determine the long-term effects of these agents in patients with HFPEF. As understanding of the mechanisms and patient-specific responses to therapies evolves, the clinical landscape for managing HFPEF is anticipated to expand significantly.
