What should you know about severe congestive heart failure?

Heart failure does not mean that the heart has stopped. Reduced pumping or filling can raise pressure in the heart and cause fluid to collect in the lungs, legs, or abdomen. Breathlessness, tiredness, a cough, a fast or irregular heartbeat, and swollen ankles can occur. A symptom such as swollen ankles can be a presentation of heart failure, but it can also have other causes.

Severity can change over time. An infection, a heart rhythm problem such as atrial fibrillation, high blood pressure, missed medicines, excess salt, or changes in kidney function may worsen symptoms. Your clinician may assess your breathing, weight trend, blood pressure, heart rhythm, medicines, and fluid balance.

Take prescribed medicines on the schedule given and do not stop them because you feel better or because you are passing more urine. Keep a written list of medicines, including non-prescription pain relievers and supplements. A chronic disease review can help check symptoms, doses, kidney tests, blood pressure, and your plan for worsening symptoms.

Follow the fluid, salt, activity, and monitoring advice made for you. Record changes in breathlessness, swelling, energy, and weight if your care team has asked you to monitor them. Rest between tasks, avoid smoking, and arrange follow-up after any hospital visit or medicine change.

Seek emergency help for severe breathlessness at rest, blue or grey lips, fainting, new confusion, chest pressure, or coughing up pink frothy fluid. Sit upright while waiting and do not drive yourself if you feel faint or severely short of breath.

Contact your medical team promptly if swelling is increasing, breathing is harder when lying down, palpitations are new or persistent, or you cannot keep medicines down. A sudden change matters even when the symptom itself seems familiar.

Ask which symptoms should trigger a same-day call, how to monitor fluid or weight, whether any medicine needs review, and what to do if a dose is missed. Ask how atrial fibrillation or hypertension may affect your plan and when your next chronic disease review is due.
