Heart failure is manageable — but needs daily attention
Heart failure doesn't mean the heart has stopped — it means the heart isn't pumping as efficiently as it should. With the right management, many people with heart failure live well for years. But it requires consistent daily attention to medications, fluid balance, and warning signs.
Daily monitoring
Heart failure management at home revolves around a few key metrics:
- Daily weight: Weigh at the same time each morning, after going to the toilet, before eating. A gain of 2kg (4.4lbs) or more over two to three days can indicate fluid retention and needs medical attention.
- Fluid intake: Many heart failure patients are on a fluid restriction (typically 1.5–2 litres per day). Track intake carefully — this includes tea, coffee, soup, and ice cream.
- Blood pressure: Monitor regularly, especially if medication doses change.
- Symptoms log: Track breathlessness, swelling (especially ankles and feet), and energy levels day to day.
Medications are non-negotiable
Heart failure medications are complex and precisely balanced. The typical regime may include:
- ACE inhibitors or ARBs (to reduce strain on the heart)
- Beta-blockers (to slow and steady the heart rate)
- Diuretics (to remove excess fluid — these are often the ones that need dose adjustments)
- Mineralocorticoid receptor antagonists (additional fluid management)
Never adjust doses without medical advice. Even feeling "fine" isn't a reason to skip tablets — they're preventing things from getting worse.
Recognising worsening symptoms
Know the signs that heart failure is becoming less controlled:
- Increasing breathlessness, especially when lying flat or at night
- Swollen ankles, legs, or abdomen
- Rapid weight gain (2kg+ in 2–3 days)
- Needing more pillows to sleep comfortably
- Persistent cough, especially with pink or frothy sputum
- Increasing fatigue and reduced ability to do daily activities
If you notice these signs, contact the heart failure nurse or GP the same day. Early intervention can often prevent a hospital admission.
Diet and lifestyle
- Reduce salt intake — salt causes fluid retention. Avoid adding salt to food and check labels on processed foods.
- Stay active within limits — gentle exercise (walking, light gardening) is beneficial. Ask the medical team for guidance on what's safe.
- Avoid alcohol or limit it strictly as advised.
- Get a flu jab and pneumonia vaccination — respiratory infections are particularly dangerous with heart failure.
Emotional impact
Heart failure can be frightening for both the person living with it and their family. The unpredictability — good weeks followed by bad weeks — is emotionally exhausting. Depression is common and understandable, but it's treatable. Encourage your loved one to talk about how they feel, and don't ignore your own emotional needs either.
