According to the Heart Failure Society of America, an estimated 8.5 million Americans will develop congestive heart failure by 2030.[1] This condition is characterized by the heart’s inability to pump blood throughout the body effectively.
The heart’s impaired ability to effectively circulate blood may lead to a range of complications. These complications not only affect the heart itself but also other bodily organs and systems.
But what causes congestive heart failure? What are the symptoms you should look out for? And which management strategies can you employ to improve your quality of life and prevent complications?
Congestive Heart Failure and Its Effect on The Body
Congestive heart failure is a condition where the heart cannot effectively pump blood throughout the body. As a result, fluid builds up in your lungs and legs.
The issue starts when your heart chambers cannot pump enough blood to the various parts of the body. Because it cannot pump blood as it should, blood returns to the heart faster than the heart can pump it out again.
Blood and fluids back up into your tissue and veins. We refer to this backing up of fluids as congestion. This could result in a fluid buildup in the lungs and swelling in your extremities, most notably the legs.
The heart’s inability to properly pump blood also means that oxygen, which is carried in the blood, does not reach all your body’s organs. This could cause further health issues.
Kidney failure could also result when they do not receive enough blood, causing them to retain more water and sodium.
Types of Congestive Heart Failure
There are several types of congestive heart failure.
- Left-Sided Congestive Heart Failure – This is the most common type of congestive heart failure. It is the result of the heart’s left ventricle not adequately pumping blood from the heart to the rest of the body. We also find two types of left-sided congestive heart failure: systolic and diastolic heart failure.
- Systolic Heart Failure – When the left ventricle does not properly contract, there is a reduction in force during a heart contraction that results in blood not being pumped properly.
- Diastolic Failure – The result of the muscle in the left ventricle becoming stiff. This means it can no longer relax, and the heart no longer fully fills with blood between heartbeats. This results in a reduced blood supply to other parts of the body.
- Right-Sided Congestive Heart Failure – This is the result of the right ventricle failing in its ability to pump blood to the lungs. As a result of this, blood backs up into the blood vessels. This, in turn, causes fluid retention in the lower extremities, i.e., the legs, as well as the abdomen and other organs.
Common Causes of Congestive Heart Failure
Congestive heart failure could have many causes.[2] The four most common of these include:
- Ischemic heart disease – also referred to as coronary heart disease (CHD) or coronary artery disease (CAD), the condition is associated with blocked coronary arteries that reduce blood flow and oxygen to the heart.
- Chronic obstructive pulmonary disease (COPD) – a progressive lung condition that reduces oxygen levels and puts strain on the right heart ventricle.
- Hypertensive heart disease (resulting from high blood pressure) – results from chronic hypertension that causes structural changes to the heart muscle, particularly the left ventricle.
- Rheumatic heart disease – an inflammatory condition that causes damage to the heart valves.
Other causes or contributing factors to congestive heart failure include:
- cardiomyopathy, a disease associated with the enlargement and thickening of the heart muscle – usually caused by a viral infection or due to genetic reasons.
diabetes- congenital heart disease, or defects in the heart structure or blood vessels developed in the womb.
- certain medications, such as those used during chemotherapy
- the use of tobacco and/or recreational drugs
- overuse of alcohol
- kidney disease
- obesity
- arrhythmia, an abnormal heart rhythm
Early Symptoms of Congestive Heart Failure
Addressing this issue early is more effective than attempting to resolve it after it has escalated. Unfortunately, many don’t notice the earliest signs of congestive heart failure.
However, seek the advice of your healthcare provider if you experience the following symptoms, as they may indicate the possibility of the condition.
The earliest signs of congestive heart failure include [3]:
- Shortness of breath (dyspnea)
- General fatigue
- Exercise intolerance
- An increased heart rate
- Lack of appetite
- Nausea
- Confusion or disorientation
- Coughing/wheezing
- Excess fluid buildup in the feet, ankles, legs, and/or abdomen (edema)
- Weight gain for no apparent reason
Identifying Congestive Heart Failure
Identifying the condition starts with a visit to your healthcare professional. There, they will ask you to describe your symptoms and take a look at your medical history. Things they may look at include:
- Your family history of heart disease
- Your tobacco and/or alcohol use
- Whether you take any medications that may contribute to your symptoms
- Any other health issues you may have
- Previous treatments received, such as radiation or chemotherapy
Your healthcare provider may also do a standard preliminary examination that includes looking at your blood pressure and other signs indicative of the condition. They would then likely advise tests that will verify their suspicions, and which may also help determine the stage you are at and the possible cause.
Tests for Congestive Heart Failure
Healthcare providers employ a range of tests to help determine whether you suffer from congestive heart failure and to determine the stage of the condition.
Blood Tests
Your healthcare provider may suggest blood tests to evaluate your troponin levels, lipid profiles, and C-reactive protein levels.
Troponin, a protein, leaks into the blood when you experience heart damage. The levels of this protein in your blood can help determine the extent of damage suffered when having a heart attack.
A lipid profile measures the amount of cholesterol and other fats in the blood. Elevated levels of low-density lipoprotein (LDL) or ‘bad’ cholesterol could indicate the buildup of plaque in the arteries. This may increase your risk of congestive heart failure.
A C-reactive protein test helps determine inflammation occurring in the arteries, which could increase your risk of heart disease.
Electrocardiogram (ECG or EKG)
In this test, you are hooked up to an electrocardiogram machine by means of electrodes. The machine measures your heart activity through these electrodes. The results printed on paper help your healthcare professional analyze and diagnose various heart issues. These include heart attacks, arrhythmias, and heart failure.
Exercise Stress Test
This test involves either walking on a treadmill or pedaling on a stationary bicycle. The test helps to determine your heart’s response while working hard. Your healthcare provider will hook you up to an electrocardiogram monitor during this time to monitor heart activity.
Chest X-Ray
This is an X-ray that looks at your lungs, bones, and heart. Although it cannot show signs of internal damage, it can show certain signs of exterior heart damage. These include the size of the heart, whether you have calcium deposits on your heart valves, and the bulging or weakening of the aorta. The aorta is the heart’s main artery.
A chest X-ray also shows whether you have fluid buildup in your lungs, which is indicative of possible congestive heart failure.
Echocardiogram
Also called a heart ultrasound, an echocardiogram helps to determine the structure of your heart and how it functions. This test may help detect various heart issues. These include valve disease and cardiomyopathy.
Cardiac Computed Tomography (CT) Scan
A CT scan uses X-rays taken from different angles to construct an image of your heart. This is done using a scanner and a computer. The result allows your healthcare provider to determine whether your heart has structural, arterial, valve, or aortic issues.
Cardiac Magnetic Resonance Imaging (MRI)
This non-invasive test helps your healthcare provider gain detailed pictures of the heart. It can determine damage in specific areas of the heart. It also helps them see how well the heart’s chambers and valves work and to study blood flow throughout the heart.
Cardiac Catheterization
For this procedure, a healthcare provider uses a narrow tube called a catheter to determine how well your heart works. The catheter enters your body via a blood vessel, either in the arm or leg. It is then navigated to the coronary arteries.
Images are shown on a large X-ray machine while the healthcare provider navigates the catheter to different areas of the heart.
Your healthcare provider can, once they have determined any damage to the heart and its various affected components, determine the extent of damage and advise on treatment options
DNA Tests
A DNA test can help determine the risk of developing congestive heart failure. This is especially useful if you have a history of heart disease in your family. It is also useful in determining proclivity in children.
This test may allow you to make lifestyle adjustments to help reduce the risk of contracting heart disease.
Stages of Congestive Heart Failure
Congestive heart failure is not something that happens overnight. The condition usually builds up over an extended period. The progression of the disease is in four stages.[4]
Stage A: Increased Risk
Although your risk of developing congestive heart failure is increased, you do not yet have damage to the heart muscle or other structures. Risk factors have increased due to:
- High blood pressure levels
- Obesity
- Coronary artery disease
- A family history of heart disease
- Diabetes
- Exposure to cardiotoxic agents that include certain chemotherapy drugs, certain illicit drugs, and heavy metals like mercury
Making lifestyle changes, monitoring the condition, and taking appropriate medications are usually the recommended methods of managing Stage A.
Stage B: Pre Heart Failure
People in this stage have symptoms of heart failure. They have the same risk factors as in Stage A, but also have the following issues:
- Increased feelings of pressure on the heart
- Structural changes to the heart
Although you may feel fine, you may experience certain discomfort while doing any strenuous physical activities. Lifestyle changes, taking appropriate medications, and monitoring the condition are the usual ways of managing the disease.
Stage C: Symptomatic Heart Failure
During this stage, you have symptoms that arise because the heart cannot pump enough blood to meet all your body’s needs. You may experience swelling in the lower extremities, fatigue, and shortness of breath.
The symptoms during this stage may be mild or severe. Severity often depends on your physical activities.
Treatment during this time is complicated.
Stage D: Advanced Heart Failure
During this stage, you may experience congestive heart failure symptoms that disrupt your ability to function normally. Hospitalization is also possible.
The symptoms during this stage include:
- Severe breathlessness
- Extreme fatigue
- Rapid weight gain usually accompanied by significant fluid buildup in the upper and lower extremities
- Chest pain
- Persistent coughing
- Nausea
- Loss of appetite
- Fainting
- Confusion
- Anxiety
- Depression
- Kidney or liver issues
Although there is no cure at this stage, you can explore various quality of life and palliative care options. Your healthcare provider is best able to advise you on this.
Care Options for Those With Congestive Heart Failure
Congestive heart failure therapies depend on the stage of the condition. Your healthcare provider may suggest the use of certain drugs. These include:
- Angiotensin-converting enzyme (ACE) inhibitors help to improve blood flow by opening narrow blood vessels.
- Vasodilators work similarly to ACE inhibitors. These are usually suggested when someone cannot tolerate ACE inhibitors.
- Beta-blockers help reduce blood pressure and heart rate. This helps to decrease the heart’s workload.
- Diuretics reduce the fluid buildup in the body.
- Anti-anxiety drugs or anti-depressants because they not only address these issues but also help lower blood pressure levels.
- Calcium channel blockers, because they help lower blood pressure levels.
If these do not work, and depending on your specific condition and issues, your healthcare professional may advise surgery.
Surgery options include angioplasty to open blocked arteries, valve repair surgery, or even a heart transplant.
Can Lifestyle Changes Manage Congestive Heart Failure Effectively?
Making certain lifestyle changes can significantly help in managing congestive heart failure. They usually form part of a comprehensive care plan.
- Follow a healthy diet that contains plenty of fresh fruits, whole grains, and vegetables. You should stay away from high-sodium and processed foods. These add to your body’s stress levels, which is bad for heart health. They may also increase your heart disease risk.
- Obesity puts a significant strain on your heart. Maintaining a healthy weight may help improve your condition.
- Your heart is a muscle. Like all muscles, it strengthens when exercised. Do, however, consider moderate forms of exercise like brisk walking or cycling. Pilates, yoga, and tai chi are also good options.
- Employ stress management techniques to help you deal with stress. Deep breathing exercises and yoga may help with this.
- If you smoke, quit. Smoking damages blood vessels.
- The excessive intake of alcohol can worsen the condition. Avoid alcohol if you have a heart condition.
- Consider using a supplement rich in Omega-3 fatty acids like Omega Max. Omega-3 fatty acids play a significant role in lowering triglyceride levels in the blood. They may also help reduce your blood pressure levels and help improve the issue of irregular heartbeats.
The Long-Term Outlook for Someone with Congestive Heart Failure
The long-term outlook depends on many different variables. These include the severity of the condition, how well they manage their treatment, and their age. Co-existing conditions like kidney disease, coronary heart disease, and diabetes may also play a role.
You can, however, significantly improve your long-term outlook if you make positive lifestyle changes like those mentioned and stick to your medication regimen. You should also closely monitor your symptoms and make sure to have regular checkups with your healthcare practitioner.
The speed at which the condition progresses varies from one person to another. This is why you need to make your healthcare provider aware of any changes, so that they can recommend the correct protocols and therapies for you to follow.
As with most health issues, early identification and management strategies may provide the best long-term outcome. There is no reason for someone with congestive heart failure not to have a long, productive life.
In Closing
Congestive heart failure is a condition that takes an extremely long time before debilitating symptoms manifest in most cases. Addressing or managing your risk factors promptly may help prevent the condition from developing or reduce the speed at which the condition progresses.
