Heart Failure

Progressive Dysfunction and Classification: Heart Failure (HF) reflects the diminished ability of the heart to effectively pump blood and meet the metabolic demands of the body. HF classification encompasses stages A to D, providing insights into disease progression and guiding therapeutic decisions.

Symptomatology and Stages: HF symptoms vary across stages. Early stages (A and B) may be asymptomatic, characterized by high cardiovascular risk. Stage C involves symptomatic HF, manifesting as exertional dyspnea, fatigue, peripheral edema, and fluid retention. Advanced HF (Stage D) signifies severe symptoms requiring specialized interventions.

Diagnostic Evaluation: Clinical evaluation integrates patient history, physical examination, and diagnostic tests. Echocardiography assesses ventricular function, dimensions, and valvular abnormalities. Brain natriuretic peptide (BNP) levels aid in HF diagnosis and severity assessment.

Treatment Approaches: HF management involves optimizing fluid balance, alleviating symptoms, and improving prognosis. Pharmacological interventions encompass diuretics, ACE inhibitors, angiotensin receptor blockers (ARBs), beta-blockers, and mineralocorticoid receptor antagonists. Device therapies, such as implantable cardioverter-defibrillators (ICDs) and cardiac resynchronization therapy (CRT), offer benefits in select cases.

Long-Term Management and Prognosis: Long-term HF management centers on lifestyle modifications, medication adherence, and regular follow-up. Patient education empowers individuals to recognize worsening symptoms and adhere to therapeutic regimens. Prognosis varies based on HF etiology, stage, and patient responsiveness to treatment.
