Heart failure and chronic kidney disease (CKD) can both arise from diabetes and high blood pressure. Moreover, having CKD can put extra pressure on the heart, and heart failure can weaken kidney function.
Heart failure is when the heart cannot pump enough blood throughout the body and certain organs do not get the amounts of blood that they need. CKD is when a person slowly loses kidney function.
This article details the connections between heart failure and CKD. It also looks at risk factors for both conditions. In addition, the article describes the symptoms, diagnosis, treatment, and outlook for heart failure and CKD.
According to the
People with CKD have an above-average risk of developing heart failure. This is partly because CKD and heart failure have two common causes: diabetes and high blood pressure.
Research suggests that having one of these two conditions can increase the progression of the other. If a person has both heart failure and CKD, they have an increased risk of:
- hospitalization or rehospitalization
- the need for intensive care
- the need for kidney replacement therapy
How does kidney failure affect the heart?
According to the
Can heart failure or heart disease affect the kidneys?
This is because, when a person has heart failure, the kidneys may not receive enough blood. Additionally, some heart failure medications can cause kidney dysfunction.
Risk factors for a condition are things that can increase a person’s risk of developing it. The
|Risk factor||CKD||Heart disease|
|having high blood pressure||✓||✓|
|having a family history of the disease||✓||✓|
|having high blood cholesterol||✓|
|consuming too much sodium||✓|
|being a male age 45 years or older||✓|
|being a female age 55 years or older||✓|
Who is more likely to develop CKD and heart failure?
Anyone can develop CKD and heart failure. However, members of African American, Hispanic, Latino, American Indian, and Alaska Native populations are
When someone has heart failure and CKD, they may develop symptoms of both conditions. Symptoms of heart failure
- shortness of breath
- chest pain
- heart palpitations
- appetite loss
CKD may not cause symptoms for some time. However, it can cause a wide range of symptoms,
- appetite loss
- sleep problems
- muscle twitches or cramps
- decreased urination
- decreased mental sharpness
- swelling of feet and ankles
- itchy skin
- high blood pressure
Like heart failure, CKD can cause chest pain, fatigue, and shortness of breath. In people with both conditions, the symptoms may be particularly acute.
If a person has heart failure, a doctor
Blood tests can also show how well the kidneys are working.
Tests to diagnose CKD include:
- blood tests to check how well the kidneys are filtering waste
- urine tests for albumin, a protein that the kidneys can release into the urine when they have damage
To diagnose heart failure, a doctor will perform an electrocardiogram, which uses sensors to record the heart’s activity.
There has not been much research on the specific treatment needs of heart failure in the context of CKD. Nonetheless, some evidence suggests that the following medications can help:
- aldosterone receptor antagonists
It is important to note that some heart failure medications can worsen symptoms of CKD. These include lithium, aminoglycosides, and nonsteroidal anti-inflammatory drugs.
Treatment for CKD involves managing the underlying cause, such as high blood pressure or diabetes.
It may be possible for people with CKD to reduce their risk of heart failure. People should also:
- avoid missing medical appointments
- take any medications their doctor prescribes
- make efforts to maintain healthy blood pressure, blood glucose, and blood cholesterol levels
- make efforts to reach or maintain a healthy BMI
- be physically active
- eat plenty of fruits, vegetables, and whole grains
- consume less sodium
According to a
In particular, having CKD increases the mortality rate, hospitalization rate, and hospital readmission rate of people with heart failure.
An individual may have several questions about kidney disease and heart failure. The
- What is my blood pressure, and what should it be?
- What are my cholesterol levels, and what should they be?
- How often should I check my blood pressure?
- Which medications should I take for blood pressure?
- What diet can help prevent kidney disease and heart failure?
- What exercise plan can help prevent kidney disease and heart failure?
- What can help with smoking cessation?
CKD is when someone has gradually worsening kidney function. Heart failure is when the heart does not pump enough blood to meet the body’s needs.
These conditions have some common risk factors, such as diabetes, high blood pressure, and a family history of the condition.
Additionally, having CKD can put pressure on the heart to pump more blood to the kidneys. Heart failure can mean that the kidneys do not receive enough blood.
