Asymptomatic heart failure: why follow-up matters

Heart failure means the heart is not filling or pumping as effectively as the body needs. Changes may be found on an echocardiogram or other assessment before breathlessness, ankle swelling or reduced exercise tolerance is noticeable. Alternatively, established symptoms may settle after effective treatment.

Feeling normal does not show whether heart structure and function have returned to normal. Clinicians interpret symptoms alongside examination, blood pressure, heart rhythm, blood tests and heart imaging. They also look for conditions that increase strain on the heart, including hypertension and atrial fibrillation.

Take each medicine at the prescribed dose even when you feel well; stopping suddenly can worsen the condition. Keep chronic disease reviews and any requested blood tests, because some medicines require kidney function and body salts to be checked. Bring an updated medicine list to appointments.

Follow the personalised advice you have received about activity, salt and fluids. Avoid smoking, and discuss alcohol use, decongestants, anti-inflammatory pain medicines and supplements with a clinician or pharmacist. Track new breathlessness, swelling, fatigue or a rapid change in weight if your care team has asked you to monitor it.

Contact your heart failure team or clinician promptly for increasing breathlessness during usual activity, needing extra pillows to breathe comfortably, waking short of breath, new ankle or abdominal swelling, worsening cough, unusual fatigue, palpitations, dizziness or a quick upward weight trend.

Call emergency services for severe breathlessness at rest, chest pressure or pain, blue or grey lips, fainting, new confusion, or coughing up pink frothy fluid. Sit upright while help is arranged if breathing is difficult, and do not drive yourself.

Ask what type of heart failure was identified, what the scan showed, and which underlying causes are being treated. Confirm your medicine plan, monitoring schedule, activity guidance, personal fluid advice, and the service to contact if warning symptoms develop.
