Understanding Congestive Heart Failure: Causes, symptoms, types, stages and treatment

Q: Do heart attacks, heart failure, and cardiac arrest mean the same?

No, here’s how they differ. Heart attack: Blockage in the blood vessels supplying blood to the heart. Heart failure: Inability of the heart to sufficiently pump blood throughout the body. Cardiac arrest: Blood circulation in the body stops and no pulse can be felt.

Congestive Heart Failure, often referred to as heart failure, is a critical condition characterised by the heart's inability to pump an adequate amount of blood to meet the body's needs. As a chronic and progressive ailment, it deteriorates over time. With reduced pumping capacity, vital organs may suffer damage due to insufficient blood supply. Additionally, fluid accumulation in the lungs, known as pulmonary oedema, leads to debilitating symptoms like shortness of breath. Despite medical interventions such as medication and lifestyle changes, the condition poses significant challenges, impacting daily life and requiring ongoing management to alleviate symptoms and improve quality of life. Here’s an overview of the disease along with its symptoms, causes and other details.

Causes of Heart Failure

There are several causes that can lead to the development of Congestive Heart Failure. Some of the most common causes are as follows.

Coronary heart disease: In this disease, the arteries cannot deliver oxygen-rich blood to the heart. This may occur due to the arteries, which supply blood to the heart, being clogged due to fatty deposits. This condition is called atherosclerosis and may cause chest discomfort which is called angina and lead to heart damage because of heart attack.
Cardiomyopathy: This may be a hereditary or acquired condition where the heart muscles get affected, leading to failure of the heart to perform its function properly.
Hypertension: Hypertension or high blood pressure can put undue pressure on the heart and this may lead to a heart failure.
Arrhythmias: Any problems in the regular beating of the heart such as atrial fibrillation impairs the contraction strength of the heart. A continuously increased heart rate is one of the main causes for the heart to pump blood less efficiently.
Congenital heart disease: This is a defect present at the time of birth and affects the normal functioning of the heart.
Heart valve disease: Any defect or damage in the valves of the heart will increase strain on the heart and make it weak.

Other than the above disease conditions, Congestive Heart Failure may occur because of metabolic causes. An overactive thyroid (hyperthyroidism) and diabetes are two common endocrine causes that may lead to a heart failure. Apart from this, certain chemotherapy drugs and consumption of alcohol can prove to be toxic to the heart muscle cells and impair their normal function.

Common symptoms of Congestive Heart Failure

Signs and symptoms of Congestive Heart Failure may include the following

Shortness of breath
Rapid or irregular heartbeat
Weakness and fatigue
Swelling in the abdomen region
Swelling in the legs, ankles, and feet
Nausea and lack of appetite
Rapid weight gain because of fluid retention
Continuous coughing or wheezing, along with white or pink blood-tinged mucus
Difficulty in concentrating or staying alert
Chest pain, if heart failure is caused by heart attack

Types of Heart Failure

The condition is segregated into the following types-

1) Left-sided heart failure

Heart failure with reduced left ventricular function (HF-rEF): Under such conditions, the left ventricle or the lower left chamber of the heart expands in size and cannot contract easily to pump enough oxygen-rich blood to the rest of the body.

Heart failure with preserved left ventricular function (HF-pEF): In this condition, the heart contracts and pumps blood normally. However, the lower chambers or the ventricles become thicker and stiffer than normal because of which they are unable to relax and fill up entirely. As a result of less blood in the ventricles, the heart also pumps out less blood to the rest of the body.

2) Right-sided heart failure: Left-sided heart failure is the most common cause for affecting the right side of your heart as well. It may also take place because of problems in other organs or due to lung issues.

How is Congestive Heart Failure diagnosed?

Congestive Heart Failure (CHF) diagnosis typically involves a comprehensive assessment by healthcare providers. This includes an inquiry into the patient's medical history, focusing on existing health conditions, family history of heart disease, tobacco and alcohol usage, history of chemotherapy or radiation, and current medication regimen. A physical examination follows, during which signs of Congestive Heart Failure and underlying conditions contributing to heart muscle weakness or stiffness are identified.

Symptoms such as shortness of breath, fatigue, and swelling are assessed alongside diagnostic tests like electrocardiograms, echocardiograms, and blood tests to measure cardiac biomarkers. This holistic approach aids in accurately diagnosing Congestive Heart Failure, enabling tailored treatment plans to manage the condition effectively while addressing any underlying health issues.

Strategies to reduce chances of developing Congestive Heart Failure

While some risk factors for heart failure, like age, family history, and race, are beyond control, lifestyle changes can significantly reduce the risk. For example:

Maintaining a healthy weight
Consuming heart-healthy foods
Engaging in regular exercise promotes cardiovascular health
Managing stress levels
Quitting tobacco
Abstaining from alcohol and recreational drugs also play crucial roles

Additionally, addressing other medical conditions that heighten heart failure risk, such as hypertension or diabetes, is vital. These proactive measures empower individuals to mitigate modifiable risk factors, enhancing overall heart health and reducing the likelihood of developing heart failure. By adopting a holistic approach to health and wellness, individuals can improve their quality of life and longevity while safeguarding against the onset of cardiovascular diseases like heart failure.

What are the Stages of Congestive Heart Failure?

There are four stages of heart failure: stage A, B, C, and D. The stages differ from each other ranging from the stage of developing elevated risk of heart failure to advanced heart failure.

Stage A: This is the stage of pre-heart failure. It shows that there are greater chances of developing heart failure if you have a strong family history of the same or have one or more of these medical conditions.

Coronary artery disease
Family history of cardiomyopathy
Hypertension
Diabetes
History of rheumatic fever
Metabolic syndrome
History of taking drugs that lead to damage of the heart muscle

Stage B: It is the stage of asymptomatic or silent heart failure. The diagnosis shows systolic left ventricular dysfunction but no symptoms of a heart failure. This stage includes people who have a heart failure as well as reduced EF (HF-rEF).

Stage C: People who fall under this stage currently have or previously had symptoms of heart failure. Some of these symptoms are as follows.

Shortness of breath
Feeling weak or fatigued
Swollen abdomen, feet, ankles, and lower legs (oedema)

Stage D: This is the advanced stage where the symptoms do not get better even with treatment. It is the final stage of heart failure.

What to expect if someone has Congestive Heart Failure?

With proper management, Congestive Heart Failure doesn't have to impede the quality of life. The prognosis depends on factors like heart muscle function, symptom severity, and treatment response. Studies suggest a shorter lifespan for those with heart failure, with survival rates ranging from 80-90% at one year to 30% at 10 years. However, individual prognoses vary due to factors such as age and gender.

Thus, personalised evaluation is essential for an accurate prognosis and tailored treatment. Adherence to the treatment plan is key to optimising outcomes, ensuring individuals with heart failure can continue to enjoy life to the fullest with appropriate care and support.

What is the typical duration of Congestive Heart Failure?

Congestive Heart Failure is a lifelong journey that demands continuous treatment and lifestyle changes. This ongoing commitment is vital for controlling symptoms, averting complications, and upholding a satisfactory quality of life. Individuals diagnosed with Congestive Heart Failure must recognise that managing the condition is an enduring process, requiring dedication to therapy and consistent adjustments.

By adhering to prescribed medications, attending regular medical appointments, and adopting healthy habits like maintaining a low-sodium diet and staying physically active, they can effectively navigate the complexities of the condition and optimise their overall health and well-being for the long term.

Treatment of Congestive Heart Failure

Although there is no cure for heart failure, the treatment aims at relieving symptoms and preventing further damage. The treatment depends upon the stage and type of heart failure and any underlying conditions. An ideal treatment plan includes the following.

1. Lifestyle modifications: You may be advised to consume less salt (due to water retention) and avoid caffeine (because of irregularities in heartbeat). You may be given advice by your doctor on the types of fluids to be consumed. Exercises should become a part of your daily routine. In addition to these, you should refrain from smoking and consuming alcohol.

2. Medications: Includes a wide range of drugs.

Vasodilators: These are known to expand blood vessels, allow easy blood flow, and reduce blood pressure.
ACE Inhibitors: Improves the functioning of the heart and increases life expectancy.
Beta blockers: Improves heart functions and chances of living longer.
Diuretics: This class of drugs does not allow fluid retention in the body.
Digitalis glycosides: Used for strengthening heart contractions.
Aldosterone inhibitors: Aids with fluid retention and improves longevity.
Anticoagulants: Helps to prevent blood clots.
Tranquillisers: Reduces anxiety levels.

3. Surgical procedures: In severe cases, a surgery may be required to open blocked arteries or replace faulty heart valves. In some patients with Congestive Heart Failure, a type of pacemaker called biventricular pacing is required to help both sides of the heart to work in unison. An implantable cardioverter defibrillator stabilises a potentially fatal heart rhythm into a normal one. Ventricular assist devices (VAD) may be used as a bridge in heart transplantation.

Living with Congestive Heart Failure

Despite the obstacles posed by Congestive Heart Failure, adults can discover joy by prioritising proper self-care. Consistent adherence to prescribed medication, engagement in regular physical activity within their limitations, and embracing a low-sodium diet are pivotal for managing the condition effectively. Vigilant monitoring of symptoms, attending medical appointments diligently, and open discussions regarding care preferences with healthcare providers and family members are indispensable.
