Heart Failure / CHF Warning Signs at Home

Heart Failure (also called Congestive Heart Failure, or CHF) can involve changes families sometimes notice at home. This page does not diagnose Heart Failure. Only a qualified professional can evaluate these changes.

Changes families may observe

  • Shortness of breath during activity, at rest, or when lying flat
  • Waking up short of breath or needing extra pillows to sleep
  • Swelling in ankles, feet, legs, or belly
  • Sudden weight change over a few days (for example, 2–3 pounds in a day or 5 pounds in a week)
  • Unusual fatigue or feeling more tired than usual with routine activities
  • Dizziness or lightheadedness
  • Persistent cough or wheezing, sometimes with white or pink-tinged mucus
  • Reduced appetite, feeling full quickly, or nausea
  • New confusion or difficulty thinking clearly
  • Palpitations (feeling of a fast or fluttering heartbeat)
  • Reduced walking tolerance — needing to stop and rest sooner than usual

Caregiver tracking prompts

  • When the shortness of breath happens (rest, activity, lying flat, at night)
  • Any new or worsening swelling and where
  • Weight trend over several days, if a scale is already used at home
  • Change in how far the person can walk before resting
  • New cough, sleep changes, or appetite changes

Keep these notes privately and share them directly with the person's healthcare professional.

Urgent red flags

  • Severe shortness of breath, especially at rest or that is worsening quickly
  • Chest pain or pressure
  • Fainting or near-fainting
  • Blue lips, fingertips, or face
  • Severe confusion
  • Sudden weakness
  • Sudden inability to walk

In the United States, call 911. Outside the United States, contact your local emergency number.
