Heart failure: update on treatment and prognosis
1Division of Cardiology, Department of Medicine, University of Miami School of Medicine, Miami, Fla., USA.
Summary
Heart failure (HF) is a serious condition, but new therapies show it can be reversed. Current treatments focus on neurohormonal blockade, unloading the heart, and supportive care to improve heart function.
Area of Science:
- Cardiology
- Internal Medicine
Background:
- Heart failure (HF) is a widespread and severe condition, impacting millions and frequently leading to hospitalization in older adults.
- It is a primary cause of mortality, with a significant proportion of deaths being sudden and arrhythmogenic.
- Traditional views considered chronic HF irreversible, but recent advancements challenge this perspective.
Observation:
- Neurohormonal blockade using beta-blockers, angiotensin receptor, and aldosterone antagonists has significantly advanced HF management.
- The concept of HF reversibility is emerging, supported by interventions like LVAD support, optimized diuretic therapy, and hemofiltration.
- Careful exercise regimen adjustments are crucial, balancing cardiac workload with the heart's reduced capacity.
Findings:
- Chronic heart failure may be biologically reversible, improving intrinsic cardiac function and structure.
- Therapeutic strategies include mechanical unloading (LVAD), pharmacological interventions (diuretics, neurohormonal blockers), and hemofiltration.
- Diuretics and sodium restriction remain fundamental for HF compensation.
Implications:
- This paradigm shift offers new hope for managing heart failure, moving beyond palliative care.
- Further research into optimizing these reversible strategies can improve patient outcomes and quality of life.
- Integrating these advanced therapies with established treatments may redefine heart failure management.
