When to Call Your Doctor About Heart Failure Symptoms


The keys to managing heart failure are to take your medications, make diet changes, exercise regularly and be active and monitor your health for new or worsening heart failure signs or symptoms. Also make sure to schedule appointments often with your health professional. Your doctor or nurse will tell you how often to visit.

When Should I Call My Doctor or Nurse?

Certain symptoms require an immediate doctor’s appointment. And, if your symptoms are discovered early, your doctor or nurse may just need to change your medications to relieve your symptoms. (Do not change or stop taking your medications without first talking to your doctor or nurse.) Make sure to contact your doctor immediately if you experience any of the symptoms listed below:

  • Unexplained weight gain — 3 pounds in a day or 5 pounds in a week.
  • Increased swelling in your ankles, feet, legs or abdomen.
  • Shortness of breath (difficulty breathing) that is new, has become worse or occurs more often, especially if it occurs when you are at rest or when you wake from sleep feeling short of breath.
  • A feeling of fullness (bloating) in your stomach.v
  • Extreme fatigue or decreased ability to complete daily activities.
  • A respiratory infection or a cough that has become worse.
  • Coughing during the night.
  • Decreased urination, dark urine.
  • Restlessness, confusion.
  • Constant dizziness or lightheadedness.

  • Fast heart rate or a heart rate around 120 beats per minute at rest.

  • A current list of your medications and dosages.
  • A list of any allergies you have.
