5 Worsening Heart Failure and Warning Signs
Learn how to recognize changes that may signal worsening heart failure, follow an individualized action plan, and distinguish symptoms that need prompt advice from emergencies.
How worsening can appear
can worsen gradually or suddenly. A change from a person’s usual pattern—such as increasing breathlessness, swelling, or fatigue—may signal fluid buildup or reduced blood flow. Follow the person’s when symptoms change.
The pattern of symptoms can offer clues. Left-sided worsening often affects breathing, while often causes swelling in the legs or abdomen. Both sides may be involved.
Changes to report promptly
Watch for worsening breathlessness, difficulty lying flat, new or increasing swelling, rapid weight gain, fatigue, weakness, palpitations, or confusion. New or worsening symptoms should be reported promptly to the heart-failure care team.
Needing more pillows to sleep or waking at night short of breath may indicate worsening congestion. For example, someone who now needs three pillows and wakes at night short of breath should contact their care team promptly rather than wait for a routine appointment.
Sudden weight gain and increased ankle swelling can indicate , even when breathing remains comfortable. Many care plans use a gain of more than 2–3 pounds in a day or 5 pounds in a week as a threshold to report. The person should use the threshold set by their own clinician.
Recognizing fluid buildup
Swelling in the legs or abdomen and weight gain can reflect fluid buildup associated with right-sided worsening. Needing more pillows to breathe while lying down is also a warning sign, but more directly reflects worsening breathlessness from lung congestion.
Do not independently change heart-failure medicine doses or fluid limits. Do not take an extra diuretic dose unless a clinician has given a specific plan.
When to seek emergency help
include severe difficulty breathing, severe chest pain, fainting, or another immediately life-threatening change. These symptoms may signal a medical emergency, including a heart attack, dangerous rhythm, or acute worsening of . Call 911 rather than waiting for a routine callback; for severe breathing difficulty with pink or blood-tinged sputum, call 911 rather than driving the person yourself.
Sudden, severe shortness of breath at rest with pink, frothy sputum may indicate fluid in the lungs, a potentially life-threatening complication. Do not wait to see whether it resolves overnight or give extra fluid.
New confusion or unusual weakness should be treated as a possible change in health and assessed promptly. Reduced blood flow or changes in the body’s fluid and salt balance can affect thinking. Sudden severe confusion or reduced responsiveness, such as being difficult to wake, needs emergency evaluation; do not assume new confusion is a normal part of aging.
