Stage A, B, C, D Heart Failure

Stage A heart failure identifies individuals at high risk for developing heart failure due to conditions like hypertension or diabetes but without symptoms or structural heart disease. Stage B involves structural heart changes, such as weakened heart muscles, but no symptoms yet. Stage C indicates the presence of symptoms like fatigue or breathlessness due to heart failure, with evidence of structural heart disease. Stage D describes advanced heart failure with severe symptoms that are difficult to control despite treatment, often requiring specialized interventions. These stages help guide management, aiming to prevent progression and improve quality of life.
