Swollen hands and heart failure

When the heart is not pumping effectively, the body may retain salt and water. Fluid can collect in the feet, ankles, legs and sometimes hands, often leaving a dent after pressure. Heart failure may also bring breathlessness, fatigue, cough, reduced exercise tolerance or a racing and irregular heartbeat. Atrial fibrillation and hypertension can affect heart function. Hand swelling alone does not confirm heart failure; heat, inflammation, medicines and kidney or vein problems can have other explanations.

If you have diagnosed heart failure, follow your agreed fluid, salt and medicine plan and check your swelling and breathing in the way your care team advised. Keep a record of changes and contact the team if rings become tight, swelling increases, or activity becomes harder. Do not alter diuretics or stop prescribed treatment without advice. A chronic disease review can help check symptoms, medicines and monitoring.

Seek emergency help for severe or sudden breathlessness, chest pain, fainting, blue or grey lips, confusion, or inability to speak comfortably because of breathing difficulty. Contact your heart-failure team promptly for rapidly worsening swelling, breathlessness when resting or lying down, a new cough, marked fatigue, or palpitations. New swelling in someone without a diagnosis also deserves medical assessment.

Ask whether your hand swelling fits fluid retention, how to monitor symptoms at home, whether medicines need review, and what change should prompt a same-day call.
