What is HFimpEF?<\/span><\/div>\n<div><span> \u2022 HFimpEF (Heart Failure with improved Ejection Fraction) is when a patient\u2019s LVEF was once \u226440% and later improves to &gt;40%, with at least a \u226510% absolute increase in LVEF.<\/span><\/div>\n<div><span> \u2022 It is now recognized as a separate heart failure (HF) phenotype.<\/span><\/div>\n<div><span> 2. Why It Matters:<\/span><\/div>\n<div><span> \u2022 Despite LVEF recovery, these patients still carry risks for adverse cardiovascular outcomes and require ongoing follow-up.<\/span><\/div>\n<div><span> 3. How Common Is It?<\/span><\/div>\n<div><span> \u2022 Estimated prevalence is ~23% among HF patients over ~3.8 years of follow-up, based on a meta-analysis of 9 studies.<\/span><\/div>\n<div><span> \u2022 Increased prevalence reflects broader use of guideline-directed medical therapy (GDMT) and standardized definitions.<\/span><\/div>\n<div><span> 4. Cardiac Remodeling (Reverse Remodeling):<\/span><\/div>\n<div><span> \u2022 LVEF recovery is linked to structural and molecular improvement in the heart muscle and reversal of fibrosis.<\/span><\/div>\n<div><span> \u2022 Reverse remodeling is key to prognosis, but does not mean full recovery.<\/span><\/div>\n<div><span> 5. Underlying Causes:<\/span><\/div>\n<div><span> \u2022 Causes vary: ischemic heart disease, myocarditis, toxic cardiomyopathy, and idiopathic forms.<\/span><\/div>\n<div><span> \u2022 Some causes are more likely to reverse, others (like genetic or infiltrative diseases) carry a higher relapse risk.<\/span><\/div>\n<div><span> 6. Imaging &amp; Biomarkers:<\/span><\/div>\n<div><span> \u2022 Advanced imaging (e.g., cardiac MRI) helps assess potential for recovery.<\/span><\/div>\n<div><span> \u2022 Biomarkers such as NT-proBNP and troponin can aid in predicting reverse remodeling and managing treatment.<\/span><\/div>\n<div><span> 7. Medical Therapy in HFimpEF:<\/span><\/div>\n<div><span> \u2022 GDMT remains critical even after recovery (ACEi\/ARB\/ARNI, beta-blockers, MRAs, SGLT2i).<\/span><\/div>\n<div><span> \u2022 Stopping meds is not currently recommended due to relapse risk.<\/span><\/div>\n<div><span> 8. DELIVER and FINEARTS-HF Trials:<\/span><\/div>\n<div><span> \u2022 These are the first RCTs to provide dedicated insights into treating HFimpEF.<\/span><\/div>\n<div><span> \u2022 DELIVER post hoc analysis showed that 25% of patients with HFimpEF were undertreated (received \u22641 HF medication).<\/span><\/div>\n<div><span> 9. Special Populations:<\/span><\/div>\n<div><span> \u2022 Ischemic HFimpEF: Needs revascularization + secondary prevention (statins, antiplatelets).<\/span><\/div>\n<div><span> \u2022 Genetic Cardiomyopathies: Some mutations (e.g., LMNA, TTN, FLNC) are linked to arrhythmic risk despite LVEF recovery.<\/span><\/div>\n<div><span> \u2022 ICD may still be warranted in some.<\/span><\/div>\n<div><span> 10. Role of Genetic Testing:<\/span><\/div>\n<div><\/div>\n<div><span> \u2022 Useful in familial or idiopathic cases.<\/span><\/div>\n<div><span> \u2022 Helps in identifying patients at high risk of late deterioration or arrhythmias.<\/span><\/div>\n<div><\/div>\n<div><span> 11. Ongoing Trials:<\/span><\/div>\n<div><\/div>\n<div><span> \u2022 PROSPER-HF: Sacubitril\/valsartan vs. valsartan in HFimpEF.<\/span><\/div>\n<div><span> \u2022 WEAN-HF: Evaluating when\/if GDMT can be safely withdrawn.<\/span><\/div>\n<div><span> \u2022 Other trials explore therapy tapering and personalized care pathways.<\/span><\/div>\n<div><\/div>\n<div><span> 12. Unresolved Questions:<\/span><\/div>\n<div><\/div>\n<div><span> \u2022 What\u2019s the best threshold for defining HFimpEF?<\/span><\/div>\n<div><span> \u2022 Can therapy be withdrawn safely?<\/span><\/div>\n<div><span> \u2022 How to stratify risk more accurately?<\/span><\/div>\n<div><span> \u2022 What is the role of cardiac MRI vs. echo in follow-up?<\/span><\/div>\n<div><\/div>\n<div><span> 13. Conclusions:<\/span><\/div>\n<div><\/div>\n<div><span> \u2022 HFimpEF is a dynamic condition: LVEF may improve, but patients remain vulnerable.<\/span><\/div>\n<div><span> \u2022 Continued GDMT and surveillance are essential.<\/span><\/div>\n<div><span> \u2022 New evidence is emerging, but many clinical decisions still rely on expert opinion and limited data.<\/span><\/div>\n<div><\/div>\n<div>DOI:<a href=\"https:\/\/doi.org\/10.1016\/j.jacc.2025.03.544\"> https:\/\/doi.org\/10.1016\/j.jacc.2025.03.544<\/a><\/div>\n<div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Heart Failure With Improved Ejection Fraction: Definitions, Epidemiology, and Management Journal of the American College of Cardiology (JACC), Volume 85, Issue 24, 2025.
