Study Notes
Definition of Heart Failure
- Heart failure is a clinical syndrome characterized by symptoms and/or signs arising from structural or functional cardiac abnormalities.
- Diagnosis requires elevated natriuretic peptide levels and evidence of pulmonary or systemic congestion.
Symptoms and Diagnosis
- Diagnosis combines symptoms, elevated natriuretic peptides (ANP, BNP, CNP), and abnormal cardiac imaging findings, typically through echocardiography.
Epidemiology of Heart Failure
- Global prevalence and incidence data indicates significant public health concerns, with various contributing factors.
- Heart failure is associated with rising healthcare demands globally.
Etiology of Heart Failure
- Major causes include ischemic heart disease, hypertension, valvular and rheumatic heart diseases, idiopathic dilated cardiomyopathy, and Chagas cardiomyopathy.
- Cancer treatments can also lead to chemotherapy and radiotherapy-induced cardiomyopathy.
Pathophysiology
- Heart failure involves backward failure from increased left ventricular filling pressures leading to pulmonary congestion.
- Forward failure is characterized by decreased cardiac output resulting in peripheral organ hypoperfusion.
Neurohormonal Activation
- Activation of neurohormonal systems, such as the sympathetic nervous system, exacerbates heart failure symptoms and progression.
- Cardinal features include cardiac and cellular remodeling impacting heart function.
Clinical Examination
- Heart failure requires comprehensive clinical examination focusing on functional status and volume overload signs.
Biomarkers
- Natriuretic peptides and troponin are crucial biomarkers for assessing heart failure severity and identifying cardiac stress.
Imaging Techniques
- Important imaging modalities include chest X-ray, echocardiography, and cardiac magnetic resonance imaging (CMR) to evaluate heart structure and function.
Management
- Management strategies include pharmacological and non-pharmacological interventions tailored to the individual patient's condition and underlying causes.
The Continuous Heart Failure Spectrum
- Heart failure presents as a spectrum influenced by risk factors, comorbidities, and progressive alterations in left ventricular ejection fraction (LVEF).
- Features of heart failure evolve bidirectionally, highlighting the need for continuous and adaptive management approaches.
