What should you know about dilated cardiomyopathy heart failure?

When the heart cannot circulate blood efficiently, fluid may build up and muscles may receive less oxygen-rich blood. People may notice breathlessness, fatigue, a cough, swollen ankles or palpitations; these symptoms can have other causes and do not establish heart failure by themselves. Assessment may include an examination, blood tests, an electrocardiogram and an echocardiogram. Clinicians also look for contributors such as hypertension, atrial fibrillation, inherited heart-muscle disease, infection or alcohol exposure.

Take prescribed heart medicines consistently and keep review appointments so symptoms, blood pressure, rhythm and kidney function can be monitored. Ask before using anti-inflammatory medicines, supplements or decongestants, because some can affect fluid balance or blood pressure. Follow the activity, salt and fluid advice tailored to you, avoid smoking, and record changes in breathlessness, weight or swelling. A chronic disease review can help coordinate medication, devices and family-risk discussions.

Call emergency services for severe or rapidly worsening breathlessness, chest pain, fainting, new confusion, blue or grey lips, or a sustained racing or irregular heartbeat with weakness. Promptly contact your care team for increasing ankle swelling, a new cough when lying down, worsening fatigue or a noticeable decline in exercise tolerance. Do not wait for a routine appointment if symptoms are escalating.

Ask how well your heart is pumping, what triggered the cardiomyopathy, which symptoms signal fluid build-up, whether relatives need assessment, and how often you need review.
