It means the heart is not pumping or filling well enough to meet the body’s needs.
The heart may be weak, stiff, affected by valve disease, damaged by a heart attack, or stressed by another condition.
Symptoms can develop slowly or worsen suddenly.
They can also resemble lung disease, kidney disease, liver disease, anemia, infection, thyroid disease, medication effects, or another medical problem.
A clinician must confirm the cause.
Call emergency services for severe or sudden breathing difficulty, chest pain, fainting, confusion, blue or gray lips, coughing pink or blood-tinged frothy mucus, or another life-threatening symptom.
People already diagnosed with heart failure should follow their personal action plan and report new or worsening symptoms promptly.
Heart Failure Symptoms Quick Answer
Common symptoms include:
- Shortness of breath during activity or at rest
- Difficulty breathing when lying flat
- Waking suddenly breathless at night
- Swelling in the feet, ankles, legs, or abdomen
- Sudden weight gain or loss
- Fatigue, weakness, or reduced exercise ability
- Persistent cough or wheeze
- Fast or irregular heartbeat
- Poor appetite, nausea, or early fullness
- Difficulty concentrating or confusion
Call emergency services now for severe breathlessness, chest pain, fainting, sudden confusion, blue or gray lips, pink frothy mucus, stroke symptoms, or collapse.
If you have diagnosed heart failure, call the care team promptly for more swelling, more breathlessness, a sudden weight change, needing extra pillows, new nighttime breathlessness, or a major drop in activity.
Use the exact weight, sodium, fluid, and medicine instructions given by your health care team.

Critical Heart Failure Safety Warning
Call emergency services for:
- Severe or sudden shortness of breath
- Gasping or inability to speak normally because of breathlessness
- Chest pain or pressure
- Fainting or collapse
- Sudden confusion
- Blue, gray, or extremely pale lips or skin
- Coughing pink, blood-tinged, or frothy mucus with breathing difficulty
- Sudden severe weakness
- Stroke signs, such as face drooping, arm weakness, or speech difficulty
- A very fast or irregular heartbeat with fainting, chest pain, or severe breathlessness
Do not:
- Drive yourself when severely unwell
- Take extra diuretic medicine unless your personal action plan says to do so
- Drink large amounts of water to “flush out” swelling
- Use potassium salt substitutes without approval
- Stop heart medicine because symptoms improve
- Exercise through chest pain, faintness, or severe breathlessness
When Heart Failure Symptoms Are an Emergency
Sudden or severe symptoms may represent acute heart failure, pulmonary edema, heart attack, a dangerous heart rhythm, pulmonary embolism, stroke, severe infection, or another emergency.
Severe Breathing Difficulty
Call emergency services when:
- Breathing is difficult at rest
- You are gasping
- You cannot speak in complete sentences
- You must sit upright to breathe
- Breathing worsens rapidly
- Breathlessness occurs with chest pain, fainting, confusion, or color change
Pink Frothy Mucus
Pink, blood-tinged, or frothy sputum with severe breathlessness can occur with fluid in the lungs.
This requires emergency assessment.
Chest Pain
Heart failure may be caused or worsened by coronary artery disease or heart attack.
Call emergency services for new chest pressure, squeezing, fullness, heaviness, or pain, especially with sweating, nausea, breathlessness, fainting, or pain spreading to the arm, jaw, shoulder, back, or upper stomach.
Fainting, Confusion, or Stroke Signs
Sudden fainting, confusion, face drooping, arm weakness, or speech trouble may indicate poor circulation, stroke, or a dangerous rhythm.
Call emergency services immediately.
Signs Heart Failure May Be Getting Worse
People with diagnosed heart failure should report changes early.
Contact the heart-failure team according to the personal action plan for:
- More shortness of breath during normal activity
- New breathlessness at rest
- Needing more pillows to sleep
- Waking suddenly breathless
- More ankle, leg, abdominal, or hand swelling
- A sudden weight change
- A tighter waistband, shoes, or rings
- More cough or wheeze
- Reduced urine output
- New dizziness
- More fatigue or weakness
- Loss of appetite or nausea
- New palpitations
- A major drop in walking or daily activity
The exact weight-change threshold should come from your health care team.
AHA notes that some patients are instructed to report gains of more than two or three pounds in a day or more than five pounds in a week, but your personal threshold may be different.
Do not wait for every symptom to appear.
Main Heart Failure Symptoms Explained
1. Shortness of Breath
Breathlessness may occur:
- While walking
- On stairs
- During light chores
- When bending
- At rest in more severe cases
Fluid in the lungs can make breathing harder.
Reduced blood flow, anemia, lung disease, deconditioning, and other conditions can also contribute.
Sudden or severe breathlessness is an emergency.
2. Trouble Breathing When Lying Flat
Orthopnea means breathing becomes harder when lying flat.
You may:
- Need additional pillows
- Sleep in a chair
- Feel chest heaviness when flat
- Avoid lying down
New or worsening orthopnea should be reported promptly.
3. Waking Breathless at Night
Paroxysmal nocturnal dyspnea means waking suddenly with severe breathlessness after lying down.
You may need to sit or stand to breathe.
This symptom can also occur with sleep apnea, asthma, lung disease, reflux, or panic.
It requires medical assessment.
4. Swelling
Fluid can collect in:
- Feet
- Ankles
- Lower legs
- Thighs
- Abdomen
- Hands
Swelling can also result from kidney disease, liver disease, vein disease, pregnancy, medication, infection, or prolonged sitting.
Do not assume swelling is heart failure without assessment.
5. Sudden Weight Change
A rapid increase may reflect fluid retention.
Weight loss can occur with poor appetite, reduced absorption, muscle loss, or advanced disease.
A sudden change matters more than a single isolated number.
Follow your care team’s threshold.
6. Fatigue and Weakness
Reduced circulation, muscle changes, poor sleep, anemia, kidney disease, medication, depression, and other factors can cause fatigue.
Report a clear decline in normal tasks or walking ability.
7. Cough or Wheeze
Heart failure can cause a persistent dry cough or wheeze, especially at night or when lying down.
Seek emergency care for pink frothy sputum or severe breathing difficulty.
8. Fast or Irregular Heartbeat
Some people feel:
- Fluttering
- Racing
- Pounding
- Skipped beats
Heart rhythms can cause or worsen heart failure.
Seek urgent care when palpitations occur with chest pain, fainting, severe dizziness, or severe breathlessness.
9. Poor Appetite, Nausea, or Early Fullness
Fluid in the abdomen, reduced gut blood flow, liver congestion, medicine, or another illness may cause:
- Early fullness
- Nausea
- Bloating
- Loss of appetite
- Unplanned weight loss
Persistent symptoms need review because inadequate nutrition can worsen weakness.
10. More Urination at Night
Fluid from the legs can return to the bloodstream when lying down.
Diuretics, diabetes, kidney disease, prostate conditions, caffeine, and sleep disorders can also increase nighttime urination.
11. Difficulty Concentrating or Confusion
Reduced circulation, low oxygen, low sodium, kidney dysfunction, infection, medication, or poor sleep may contribute.
Sudden confusion is an emergency.
12. Reduced Exercise Ability
A gradual decline may appear as:
- Shorter walking distance
- More rest breaks
- Difficulty with stairs
- Avoiding chores
- Stopping usual hobbies
Track changes rather than comparing yourself with other people.
13. Neck Vein Distension
A clinician may identify increased neck-vein pressure during examination.
It is not reliable for most people to assess themselves.
14. Blue or Gray Lips or Skin
Color changes can indicate low oxygen or circulation.
They may appear differently across skin tones.
Call emergency services when color change occurs with breathlessness, chest pain, confusion, or fainting.
What Does Heart Failure Mean?
Heart failure is a clinical syndrome in which an abnormality of heart structure or function causes symptoms, signs, or both.
It does not mean the heart has stopped.
The problem may involve:
- Weak pumping
- Stiff filling
- Valve disease
- Abnormal rhythm
- High pressure inside the heart
- Fluid retention
“Congestive heart failure” describes heart failure with fluid buildup.
Some people have heart failure without obvious swelling.
Treatment can reduce symptoms, lower hospital risk, improve function, and help many people live longer.
What Causes Heart Failure?
Heart failure usually develops because another condition damages or overworks the heart.
Causes and contributors include:
- Coronary artery disease
- Previous heart attack
- Long-standing high blood pressure
- Heart-valve disease
- Cardiomyopathy
- Abnormal heart rhythms
- Myocarditis
- Congenital heart disease
- Diabetes
- Chronic kidney disease
- Sleep apnea
- Thyroid or other endocrine disease
- Heavy alcohol use
- Stimulant drugs
- Some chemotherapy and radiation treatments
- Pregnancy-related cardiomyopathy
- Infiltrative disease such as cardiac amyloidosis
- Severe infection or prolonged high-output states
Finding the cause matters because treatment may target the underlying condition.
Types of Heart Failure
Ejection fraction is the percentage of blood pumped out of the left ventricle with each contraction.
It is one part of diagnosis and does not fully describe symptoms or prognosis.
Heart Failure With Reduced Ejection Fraction
HFrEF usually means a left-ventricular ejection fraction of 40% or lower.
The heart’s pumping ability is reduced.
Heart Failure With Mildly Reduced Ejection Fraction
HFmrEF usually describes an ejection fraction of 41% to 49% with evidence supporting heart failure.
Heart Failure With Preserved Ejection Fraction
HFpEF generally involves an ejection fraction of 50% or higher with evidence of elevated filling pressures or related abnormalities.
The heart may be stiff and fill poorly even though the percentage pumped out appears preserved.
Heart Failure With Improved Ejection Fraction
Some people previously had an ejection fraction of 40% or lower that later improved above 40%.
Medicine is usually continued unless the heart-failure team advises otherwise because relapse can occur.
Left-Sided and Right-Sided Heart Failure
Left-sided failure often causes lung congestion and breathlessness.
Right-sided failure often causes leg and abdominal swelling.
Many people have features of both.
Acute and Chronic Heart Failure
Acute heart failure starts or worsens quickly and may need emergency hospital treatment.
Chronic heart failure requires long-term monitoring and treatment.
How Heart Failure Is Diagnosed
Diagnosis uses medical history, examination, laboratory tests, and heart imaging.
Symptoms alone are not enough.
Medical History and Examination
The clinician may ask about:
- Breathlessness
- Swelling
- Weight changes
- Sleep position
- Nighttime symptoms
- Exercise ability
- Heart disease and family history
- Medicine, alcohol, and drug exposure
The examination may assess heart rhythm, blood pressure, oxygen level, lung sounds, swelling, neck veins, and liver or abdominal congestion.
BNP or NT-proBNP
These blood tests can support diagnosis.
Results can be affected by age, kidney function, obesity, rhythm disorders, and other conditions.
A number must be interpreted with the full clinical picture.
Electrocardiogram
An ECG checks heart rhythm and may show previous heart damage or other abnormalities.
Echocardiogram
An echocardiogram assesses:
- Ejection fraction
- Heart size
- Wall movement
- Valve function
- Filling patterns
- Pressure estimates
Other Tests
Testing may include:
- Chest X-ray
- Kidney, liver, thyroid, electrolyte, iron, and blood-count tests
- Coronary artery evaluation
- Cardiac MRI
- Stress testing
- Rhythm monitoring
- Sleep testing
- Genetic testing in selected cases
How Heart Failure Is Treated
Treatment depends on the cause, ejection fraction, symptoms, blood pressure, kidney function, potassium, heart rhythm, pregnancy status, other illnesses, and personal goals.
Treatment may include:
- Guideline-directed medicines
- Diuretics for fluid congestion
- Blood pressure control
- Diabetes and kidney treatment
- Valve or coronary procedures
- Rhythm treatment
- Pacemakers or defibrillators in selected patients
- Cardiac rehabilitation
- Sleep-apnea treatment
- Iron treatment in selected patients
- Advanced therapies, including mechanical support or transplant evaluation
- Palliative and supportive care at any stage when helpful
Heart failure is usually a long-term condition.
Treatment can improve symptoms, function, quality of life, and survival.
Do not stop medicine because the ejection fraction or symptoms improve.
Common Heart Failure Medicine Groups
Not every medicine suits every type of heart failure.
Doses are usually started and adjusted gradually.
Blood pressure, kidney function, potassium, symptoms, and side effects may require monitoring.
Core Therapy for Reduced Ejection Fraction
The 2022 AHA, ACC, and HFSA guideline identifies four foundational medicine classes for many patients with HFrEF:
- ARNI, or an ACE inhibitor or ARB when appropriate
- An evidence-based beta blocker
- A mineralocorticoid receptor antagonist
- An SGLT2 inhibitor
Diuretics
Diuretics help remove extra sodium and fluid.
They can reduce swelling and lung congestion.
They require monitoring for dehydration, kidney changes, low sodium, low or high potassium, and low blood pressure.
Do not take extra tablets without a written plan.
Other Medicines
Depending on the type and cause, treatment may include:
- Hydralazine and nitrates
- Ivabradine
- Digoxin
- Anticoagulants for selected rhythm or clot conditions
- Cholesterol medicine
- Iron treatment
- Other cause-specific treatment
Preserved and Mildly Reduced Ejection Fraction
Treatment focuses on congestion, blood pressure, SGLT2 inhibitors when appropriate, atrial fibrillation, coronary disease, obesity, diabetes, kidney disease, sleep apnea, and other contributors.
The plan is individualized.
Daily Weight and Symptom Tracking
The heart-failure team may ask you to monitor:
- Weight
- Blood pressure
- Heart rate
- Swelling
- Breathlessness
- Sleep position
- Fluid intake
- Diuretic use
- Exercise ability
How to Weigh Yourself
- Use the same scale.
- Weigh at the same time, often in the morning.
- Use similar clothing.
- Weigh after urinating and before breakfast when practical.
- Record the result.
Use Your Personal Threshold
Some action plans use a gain of more than two or three pounds in one day or more than five pounds in one week.
That is not universal.
Use the exact number and action given by your health care team.
A sudden weight loss can also be important.
Written Action Plan
Ask the team to clearly state:
- Which symptoms require a same-day call
- Which symptoms require emergency care
- Whether and when a diuretic dose may change
- Your sodium and fluid targets
- Your weight threshold
- Whom to call outside office hours
Sodium, Fluid, and Potassium Safety
Sodium
Excess sodium can increase fluid retention.
Common sources include:
- Processed meat
- Canned soup
- Bread and rolls
- Cheese
- Restaurant meals
- Sauces and condiments
- Packaged snacks
- Ready meals
There is no single sodium target for every patient.
Follow the amount given by the heart-failure team.
Read Nutrition Facts labels and compare similar products.
Fluid
Not everyone with heart failure needs the same fluid limit.
Restriction may be used for selected people with severe congestion, low blood sodium, advanced disease, or other specific conditions.
Water, tea, coffee, milk, soup, ice, gelatin, and high-water foods may count when a fluid limit is prescribed.
Do not restrict or force fluid without instructions.
Potassium
Heart-failure medicines can raise or lower potassium.
ACE inhibitors, ARBs, ARNI, mineralocorticoid receptor antagonists, and potassium-sparing diuretics may raise it.
Loop and thiazide diuretics may lower it.
Kidney function also matters.
Do not use potassium supplements or potassium-based salt substitutes without approval.
Exercise and Cardiac Rehabilitation
Regular movement can improve function and quality of life for many people with stable heart failure.
The plan should match symptoms, fitness, heart rhythm, blood pressure, and other medical conditions.
Ask Before Starting
Ask:
- Is exercise safe now?
- Should I attend cardiac rehabilitation?
- What intensity is appropriate?
- Should I monitor heart rate or symptoms?
- What should make me stop?
Stop and Seek Help
Stop activity for:
- Chest pain
- Severe breathlessness
- Fainting or near-fainting
- Severe dizziness
- A new dangerous heartbeat sensation
- Symptoms that do not improve with rest
Do not exercise during acute worsening unless the treatment team advises it.
Over-the-Counter Medicine and Supplement Safety
Some nonprescription products can worsen blood pressure, kidney function, fluid retention, or medicine interactions.
Ask a pharmacist or clinician before using:
- Ibuprofen, naproxen, and other NSAIDs
- Cold and sinus decongestants
- Effervescent products high in sodium
- Herbal diuretics
- Licorice root
- Potassium supplements
- Potassium salt substitutes
- Stimulant weight-loss products
- Energy supplements
- Concentrated herbal extracts
Do not stop a prescribed medicine because an online source lists a possible side effect.
Contact the prescriber.
Sick-Day and Procedure Instructions
Some medicines may need special instructions during vomiting, diarrhea, fasting, severe illness, or surgery.
Ask for a written sick-day plan.
Do not make changes on your own.
Pregnancy and Heart Failure
Pregnancy increases blood volume and heart workload.
Heart failure can occur in people with existing heart disease or as pregnancy-related cardiomyopathy.
Seek urgent assessment for:
- Severe or rapidly worsening breathlessness
- Breathlessness at rest
- Chest pain
- Fainting
- New rapid swelling
- Palpitations with severe symptoms
- Pink frothy sputum
Normal pregnancy can cause mild breathlessness and ankle swelling, but severe, sudden, or progressive symptoms require assessment.
Not every heart-failure medicine is safe during pregnancy or breastfeeding.
Preconception and maternity-cardiology guidance are important.
Risk Reduction and Long-Term Care
Not every case can be prevented.
Risk may be reduced by:
- Controlling high blood pressure
- Treating coronary artery disease and high cholesterol
- Managing diabetes
- Protecting kidney health
- Avoiding smoking and stimulant drugs
- Limiting or avoiding alcohol
- Being physically active
- Treating sleep apnea
- Using heart-toxic cancer treatment monitoring when indicated
- Taking medicine as prescribed
- Attending follow-up
Vaccination
Ask the care team about influenza, pneumococcal, COVID-19, and other recommended vaccines.
Respiratory infections can place extra stress on the heart.
Mental Health and Supportive Care
Depression, anxiety, caregiver strain, and financial or transportation barriers can affect heart-failure care.
Ask for support.
Palliative care is not limited to the final stage of illness.
It can help with symptoms, decisions, and quality of life alongside active treatment.
Common Heart Failure Myths
Myth: Heart Failure Means the Heart Has Stopped
No. The heart is still beating but is not pumping or filling well enough.
Myth: Swollen Ankles Always Mean Heart Failure
No. Kidney, liver, vein, medication, pregnancy, and other problems can cause swelling.
Myth: A Normal Ejection Fraction Rules Out Heart Failure
No. Heart failure with preserved ejection fraction can occur when the heart is stiff or filling pressures are abnormal.
Myth: Everyone Needs the Same Fluid Restriction
No. Fluid advice is individualized.
Myth: Everyone Needs the Same Sodium Limit
No. Use the target provided by the heart-failure team.
Myth: More Water Helps Remove Fluid
No. Forced fluid intake may worsen congestion or low sodium.
Myth: Symptoms Improving Means Medicine Can Stop
No. Treatment may be controlling the condition. Stopping medicine can cause relapse.
Myth: Extra Diuretics Are Always Safe
No. Extra doses can cause kidney injury, low blood pressure, dehydration, and electrolyte problems.
Myth: Heart Failure Cannot Be Treated
No. Treatment can improve symptoms, reduce hospitalizations, and help many people live longer.
Conclusion
Common heart failure symptoms include shortness of breath, difficulty lying flat, waking breathless, swelling, sudden weight change, fatigue, cough, palpitations, poor appetite, and reduced exercise ability.
Heart failure does not mean the heart has stopped.
Symptoms can be caused by many different conditions, so diagnosis requires medical history, examination, blood tests, ECG, echocardiography, and other testing as needed.
Call emergency services for severe breathlessness, chest pain, fainting, sudden confusion, blue or gray lips, pink frothy mucus, stroke symptoms, or collapse.
If you have diagnosed heart failure, follow your personal action plan and report worsening symptoms early.
Use the medicine, daily weight, sodium, fluid, potassium, and exercise instructions provided by your health care team.
Early reporting and consistent treatment can prevent a small change from becoming a medical crisis.

Frequently Asked Questions
What are the first signs of heart failure?
Possible early signs include shortness of breath during normal activity, unusual tiredness, ankle swelling, reduced exercise ability, cough, weight change, or difficulty breathing when lying flat.
Does heart failure mean the heart has stopped?
No. Heart failure means the heart is not pumping or filling well enough to meet the body’s needs. Cardiac arrest means the heart has stopped pumping effectively.
What does heart failure breathlessness feel like?
It may occur during walking, stairs, chores, bending, lying flat, or sleep. Severe breathlessness at rest or sudden worsening requires emergency care.
Can heart failure cause swollen ankles?
Yes. Fluid may collect in the feet, ankles, legs, or abdomen. Kidney, liver, vein, medication, and other problems can also cause swelling.
What weight gain should a person with heart failure report?
Use the threshold provided by the heart-failure team. Some plans use more than two or three pounds in a day or five pounds in a week, but this is not universal.
Can a person have heart failure with a normal ejection fraction?
Yes. Heart failure with preserved ejection fraction can occur when the heart is stiff or filling pressures are abnormal even when the pumping percentage appears preserved.
How is heart failure diagnosed?
Diagnosis may include medical history, examination, BNP or NT-proBNP, ECG, echocardiography, chest imaging, and blood tests for kidney, liver, thyroid, anemia, iron, and electrolytes.
Can heart failure be treated?
Yes. Treatment may include guideline-directed medicines, diuretics, procedures, devices, cardiac rehabilitation, treatment of the cause, and ongoing monitoring.
Does everyone with heart failure need a fluid restriction?
No. Fluid guidance is individualized. Restriction may be appropriate for selected patients with congestion, low sodium, advanced disease, or another specific reason.
Should a person take extra water pills for swelling?
Only when a clinician has provided a specific action plan. Extra diuretics can cause dehydration, kidney injury, low blood pressure, and electrolyte problems.
When are heart failure symptoms an emergency?
Call emergency services for severe or sudden breathlessness, chest pain, fainting, confusion, blue or gray lips, pink frothy mucus, stroke signs, collapse, or another life-threatening symptom.
Is this article medically reviewed?
No. It was written and source checked using authoritative references, but it has not been medically reviewed by a doctor or cardiologist.
