Congestive heart failure, or heart failure, causes symptoms, including a cough. A congestive heart failure cough may occur due to fluid buildup in the lungs or as a side effect of medication.
A cough from congestive heart failure can mean the condition is worsening. Treatment for coughing due to heart failure may involve medication and lifestyle changes to reduce fluid retention and improve heart function.
The article below covers what causes coughing in congestive heart failure, how to treat it, and when to contact a doctor.
A cough that occurs as a symptom of heart failure is usually persistent and produces white or pink blood-tinged mucus. However, if the cough results from a medication for heart failure, it may sound dry.
Coughing due to congestive heart failure may mean the heart condition is becoming worse. According to a 2017 study, lung congestion is the primary cause of hospitalization in people with heart failure.
A cardiac cough involves coughing that develops as a result of heart issues, not lung conditions. A few factors can lead to a cardiac cough, which we explore in more detail below.
When a person has heart failure, the heart
When fluid retention occurs in the lungs, the body attempts to clear the lungs, which
Cardiac medication side effects
Medications to treat heart failure may improve heart function, but they can cause side effects. Coughing is one possible side effect of certain cardiac medications.
For example, healthcare professionals
A cough due to medication side effects may develop as soon as a few hours after a person takes the first dose or as late as months afterward.
When the heart does not pump blood effectively, it may cause several symptoms throughout the body. The severity of symptoms may depend on the stage of heart failure.
According to the
Treatment for coughing due to congestive heart failure involves decreasing the excess fluid in the lungs and treating underlying heart function issues.
We discuss treatment options in more detail below.
People with congestive heart failure may also receive medication to improve heart function. These medications may reduce the heart rate, improve blood pressure, and help the heart beat more efficiently.
- ACE inhibitors
- angiotensin receptor blockers
- aldosterone agonists
- SGLT2 inhibitors
If ACE inhibitors are causing a cough, healthcare professionals
A healthcare professional may advise a person to track and limit their daily liquid intake to decrease fluid buildup, which may reduce coughing.
People with congestive heart failure can take other steps to manage their condition, such as:
Anyone with symptoms of congestive heart failure should contact a healthcare professional. Individuals with congestive heart failure require a treatment plan to decrease symptoms and slow the progression of the condition.
People who have a diagnosis of congestive heart failure
- experience swelling in the ankles, feet, or legs
- cough up blood or pink-tinged mucus
- gain more than 3 pounds in 24 hours, which may signal fluid retention
- have increased shortness of breath or exercise intolerance
A person should seek emergency treatment if the following symptoms develop:
- chest pain
- extreme shortness of breath
- bluish skin
Here are some answers to frequently asked questions about heart failure and coughing.
What does a congestive heart failure cough sound like?
A cough due to congestive heart fluid often sounds “wet.” Healthcare professionals describe a wet cough as one that produces rales, or crackles, when they listen to it with a stethoscope. Crackles sound like rattling or popping.
How do I know if my cough is heart-related?
Individuals may not know whether their cough is heart-related unless they have certain diagnostic tests. A heart-related cough can have similar symptoms to certain lung diseases.
Congestive heart failure occurs when the heart cannot pump enough blood throughout the body to meet demands. This may cause a buildup of fluid in the body, including in the lungs.
Coughing develops as a reaction to irritation from excess fluid in the lungs. Treatment includes medication to improve heart function and decrease fluid retention.
