• Symptoms of Heart Failure in Adults


    Heart failure does not mean that your heart has stopped working entirely, but rather that it is struggling to keep up with the demands of your body for oxygen and nutrient-rich blood. While patients who suddenly develop heart failure (acute heart failure) will have pronounced symptoms, others may find that their symptoms develop gradually over time. The symptoms of heart failure are also symptoms of many other conditions, and many older patients may at first assume they are signs of aging.

    If you experience chest pain or fainting—or have shortness of breath with chest pain, fainting or coughing with pink blood-tinged mucus—immediately seek emergency medical treatment.

    Symptoms of heart failure in adults include the following:

    • Shortness of breath (including shortness of breath while lying down flat)
    • Tiredness or fatigue
    • Weakness
    • Dizziness
    • Swelling (edema) in legs, ankles and feet
    • Swelling in abdomen
    • Rapid weight gain
    • Arrhythmias (heart rhythm problems)
    • Coughing or wheezing, sometimes accompanied by pink blood-tinged mucus
    • Need to urinate at night
    • Confusion or difficulty thinking
    • High blood pressure or low blood pressure
    • Loss of appetite and/or nausea
