Understanding the basics of heart failure: definition and types
Heart failure, also known as congestive heart failure, is a condition in which the heart is unable to pump enough blood to meet the body’s needs. This can happen for a variety of reasons and can lead to a number of symptoms and complications.
Types of heart failure
There are two main types of heart failure: systolic and diastolic.
-
Systolic heart failure occurs when the heart muscle is unable to contract effectively, which results in a decreased ability to pump blood. This is the most common type of heart failure.
-
Diastolic heart failure occurs when the heart muscle is stiff and unable to relax properly, which results in a decreased ability to fill with blood. This is less common than systolic heart failure.
It’s also important to note that heart failure can be classified as left-sided or right-sided, depending on which side of the heart is affected. Left-sided heart failure affects the left ventricle, which is responsible for pumping oxygenated blood to the body. Right-sided heart failure affects the right ventricle, which is responsible for pumping blood to the lungs to receive oxygen.
Causes of heart failure
There are many potential causes of heart failure, including:
- Coronary artery disease, which occurs when the blood vessels that supply the heart muscle with blood and oxygen become narrowed or blocked.
- High blood pressure, which can cause the heart to work harder and lead to heart failure over time.
- Heart valve problems, such as stenosis or regurgitation, can make it harder for the heart to pump blood.
- Cardiomyopathy, which is a disease of the heart muscle that can lead to heart failure.
- Heart infections, such as endocarditis or myocarditis, can damage the heart muscle and lead to heart failure.
- Diabetes, which increases the risk of heart failure.
- Lung disease, such as chronic obstructive pulmonary disease (COPD) can put extra strain on the heart.
It’s important to note that heart failure can be caused by a combination of factors and in some cases, the exact cause is unknown.
Risk factors
Certain conditions and lifestyle choices can increase the risk of developing heart failure. These include:
- Age: The risk of heart failure increases as people get older.
- Gender: Men are more likely to develop heart failure than women.
- Race: African Americans have a higher risk of heart failure than other races.
- Family history: People with a family history of heart disease are more likely to develop heart failure.
- Smoking: Smoking increases the risk of heart failure.
- Obesity: Being overweight or obese can increase the risk of heart failure.
- Excessive alcohol use: Drinking large amounts of alcohol can increase the risk of heart failure.
- Diabetes: People with diabetes have a higher risk of heart failure.
Heart failure is a serious condition that affects the ability of the heart to pump enough blood to meet the body’s needs. It can be caused by a variety of factors and can lead to a number of symptoms and complications. Understanding the basics of heart failure, including its definition, types, causes, and risk factors, is important for early detection, treatment, and prevention. If you have any concerns about heart failure, it is important to speak with your healthcare provider.
Common symptoms of heart failure and when to seek medical attention
Heart failure is a serious condition that affects the ability of the heart to pump enough blood to meet the body’s needs. It can cause a variety of symptoms, which can range from mild to severe. It’s important to be aware of the signs of heart failure and seek medical attention if you experience any of these symptoms.
Symptoms of heart failure
- Shortness of breath, especially during physical activity or when lying down. This occurs because the heart is unable to pump enough blood to meet the body’s needs, which leads to fluid buildup in the lungs.
- Fatigue, or feeling weak and tired, occurs because the heart is unable to pump enough blood to meet the body’s needs.
- Swelling, or edema, in the legs, ankles, and feet occurs because the heart is unable to pump enough blood to the body’s tissues, which leads to fluid buildup.
- Cough, or wheezing, which can be caused by fluid buildup in the lungs.
- Rapid or irregular heartbeat, which can occur as the heart tries to compensate for its inability to pump blood effectively.
- Chest pain or discomfort, which can occur as a result of reduced blood flow to the heart muscle.
It’s important to note that the symptoms of heart failure can be caused by other conditions and not everyone with heart failure will experience all of these symptoms.
When to seek medical attention
If you experience any of the above symptoms, it’s important to seek medical attention as soon as possible. Some symptoms, such as shortness of breath or chest pain, may be serious and require immediate medical attention. Other symptoms, such as swelling or fatigue, may be less severe but still warrant a visit to your healthcare provider.
If you have a history of heart disease or risk factors for heart failure, it’s important to stay in close contact with your healthcare provider and follow their recommended schedule for checkups and screenings.
Diagnosis
If your healthcare provider suspects that you have heart failure, they will conduct a physical examination and ask about your symptoms and medical history. They may also order tests such as:
- Blood tests to check for signs of heart failure or other underlying conditions.
- Chest X-ray to check for fluid buildup in the lungs.
- Echocardiogram to check the function of the heart muscle and valves.
- Cardiac MRI or CT scan to check the structure of the heart and blood vessels.
- Stress test to check how well the heart functions during physical activity.

Diagnosis and evaluation of heart failure: tests and procedures
Heart failure is a serious condition that occurs when the heart is unable to pump enough blood to meet the body’s needs. It can cause a variety of symptoms, which can range from mild to severe. If you suspect that you have heart failure, it’s important to seek medical attention and get a proper diagnosis.
Physical examination
If your healthcare provider suspects that you have heart failure, they will conduct a physical examination. This will include:
- Listening to your heart with a stethoscope to check for a rapid or irregular heartbeat, or a heart murmur, which can be caused by heart valve problems.
- Checking for swelling in your legs, ankles, and feet, which can be caused by fluid buildup.
- Checking your breathing for signs of shortness of breath or wheezing, which can be caused by fluid buildup in the lungs.
Blood tests
Your healthcare provider may also order blood tests to check for signs of heart failure or other underlying conditions. These tests may include:
- B-type natriuretic peptide (BNP) or N-terminal pro-BNP (NT-proBNP), which are markers of heart failure. High levels of these markers in the blood can indicate that the heart is not pumping effectively.
- Complete blood count (CBC) to check for anemia, which can occur as a result of reduced blood flow to the body’s tissues.
- Kidney function tests to check for kidney damage, which can occur as a result of heart failure.
- Liver function tests to check for liver damage, which can occur as a result of heart failure.
- Thyroid function tests to check for thyroid disease, which can affect heart function.
Imaging tests
Your healthcare provider may also order imaging tests to check the structure and function of your heart and blood vessels. These tests may include:
- Chest X-ray to check for fluid buildup in the lungs.
- Echocardiogram to check the function of the heart muscle and valves. An echocardiogram uses sound waves to create a picture of the heart.
- Cardiac MRI or CT scan to check the structure of the heart and blood vessels.
- Stress test to check how well the heart functions during physical activity.

Your healthcare provider will conduct a physical examination and may order blood tests, imaging tests, and other procedures to check the structure and function of your heart and blood vessels.
Treatment options for heart failure: medications, lifestyle changes, and surgery
Heart failure is a serious condition that occurs when the heart is unable to pump enough blood to meet the body’s needs. It can cause a variety of symptoms and complications, and it’s important to seek medical attention and start appropriate treatment as soon as possible. Treatment options for heart failure include medications, lifestyle changes, and in some cases, surgery.
Medications
Medications can help to improve the symptoms of heart failure and slow the progression of the disease. Medications that are commonly used to treat heart failure include:
-
Angiotensin-converting enzyme (ACE) inhibitors: These medications help to relax blood vessels and reduce the workload on the heart. ACE inhibitors also help to lower blood pressure and reduce the risk of heart attack and stroke.
-
Angiotensin receptor blockers (ARBs): These medications work in a similar way to ACE inhibitors but have a slightly different mechanism of action.
-
Beta-blockers: These medications help to slow the heart rate and reduce the workload on the heart. Beta-blockers also help to lower blood pressure and reduce the risk of heart attack and stroke.
-
Aldosterone antagonists: These medications help to prevent the buildup of fluid in the body, which can occur as a result of heart failure.
-
Diuretics: Also known as “water pills,” these medications help to remove excess fluid from the body and can be used to reduce swelling and shortness of breath caused by heart failure.
-
Digoxin: This medication helps to strengthen the heart muscle contractions and can be used to treat heart failure.
It’s important to note that the specific medications and dosages used to treat heart failure will depend on the individual patient and the severity of their condition.
Lifestyle changes
In addition to taking medications, it’s also important to make lifestyle changes to help manage heart failure and reduce the risk of complications. These changes may include:
-
Eating a healthy diet low in salt and saturated fat, and high in fruits and vegetables.
-
Exercising regularly under the guidance of a healthcare provider.
-
Quitting smoking and avoiding exposure to secondhand smoke.
-
Limiting alcohol intake.
-
Maintaining a healthy weight.
-
Managing stress through techniques such as yoga, meditation, or therapy.
-
Adhering to a schedule of regular check-ups with healthcare provider to monitor symptoms and treatment.
Surgery
In some cases, surgery may be necessary to treat heart failure. Surgical options include:
- Coronary artery bypass surgery: This procedure is used to bypass blocked or narrowed coronary arteries.
- Valve replacement or repair: This procedure is used to replace or repair heart valves that are not functioning properly.
- Heart transplantation: This procedure is used as a last resort for patients with advanced heart failure who have not responded to other treatments.
It’s important to note that not all patients with heart failure will require surgery and the decision to undergo surgery will depend on the individual patient and the severity of their condition.
