Heart Failure Late Stage Symptoms Explained

According to the American Heart Association, heart disease is the leading cause of death in adults in the U.S. Heart failure is one common type of heart disease, which can be caused by specific conditions like cardiomyopathy or by numerous risk factors like high blood pressure and diabetes. 

If you care for a loved one with heart failure or with risk factors for heart failure, it’s important to understand the disease. In particular, late stage heart failure can be distressing and uncomfortable. In this article, we’ll explain:

• The symptoms of end stage heart failure in detail
• How your loved one’s medical team can help you manage the symptoms

What Is Heart Failure? 

Heart failure occurs when the heart cannot pump blood as effectively as it should, reducing blood flow in the body. There are different types of heart failure, like left sided heart failure and right sided heart failure. These depend on which part of the heart is weak or damaged and the associated complications. There can also be different causes of heart failure.

Heart failure can be acute, but it’s more often chronic and progressive. It gets worse over time and cannot be cured other than with a heart transplant, which is not an option for many patients. 

While many factors can cause or contribute to heart failure, the underlying cause is weakness or damage in the heart muscle. Risk factors include:

• High blood pressure
• Coronary artery disease
• Heart attack
• Obesity
• Diabetes 

The Stages Of Heart Failure

Late stage or end stage heart failure is preceded by earlier stages that don’t always cause symptoms. The American Heart Association recognizes four stages of heart failure, from A to D: 

• Stage A. Stage A heart failure is considered the at-risk stage. In this stage, a patient doesn’t necessarily have heart failure but has risk factors for developing it. These include high blood pressure, obesity, diabetes, coronary artery disease, and family history. 
• Stage B. Stage B heart failure is pre heart failure. Patients at this stage are still symptomless but have risk factors and structural heart disease, increased pressure in the heart, or both. 
• Stage C. Stage C heart failure patients are symptomatic. They have some of the symptoms characteristic of heart failure, like shortness of breath or swelling. 
• Stage D. Stage D heart failure is advanced or end stage heart disease. At this stage, patients have symptoms that significantly disrupt their daily lives or require hospitalization. 

What Is End Stage Heart Failure? 

Stage D heart failure is considered advanced, or end stage. It occurs when the symptoms of heart failure become worse and disruptive. They persist, even when the patient is at rest. Many patients in this stage need hospital care. 

Doctors further divide the stages of heart failure into classes based on the severity of symptoms in stages C and D. Stage D is considered end stage heart failure, but the system is used for all patients with symptoms. 

Most physicians use the New York Heart Association Functional Classification system. The four classes are based on how limiting the patient’s symptoms are. 

• Class I. In class I, a patient might have symptoms, but they are mild and not limiting. Patients can still be physically active. 
• Class II. Class II refers to some limitations in physical activity. Patients are generally comfortable when resting, but become fatigued or experience symptoms like shortness of breath when active. 
• Class III. Class III patients are more severely limited. They still feel comfortable at rest, but even minimal activity causes significant symptoms. 
• Class IV. In class IV, heart failure patients have symptoms even when resting, and those symptoms get worse with any level of activity. Many patients in end stage heart failure are in class IV. 

By assigning a class to a patient with end stage heart failure, doctors can make better treatment decisions. They also reevaluate patients regularly to determine whether treatments are helping or should be altered. 

What Are The Symptoms Of End Stage Heart Failure? 

Heart failure can be symptomless for a while. As a progressive chronic disease, it will eventually worsen and cause noticeable symptoms. These often include shortness of breath, fatigue, chest pains, heart palpitations, coughing, weight gain, and nausea. 

Overall, patients in end stage heart failure experience significant declines in comfort and daily functioning. Any symptoms they already had get worse, they may experience new symptoms, and symptoms persist even when at rest. These are some of the characteristic signs of end stage congestive heart failure. 

Shortness Of Breath

Shortness of breath, also known as dyspnea, is one of the most common advanced heart failure signs. It can feel like:

• Breathlessness
• Tightness in the chest
• Not being able to get enough air

Difficulty breathing can be very distressing and gets worse with physical activity. In the end stage, many patients experience this symptom even when resting. Caused by fluid buildup in the lungs, dyspnea is also often worse when lying down or trying to sleep. 

Coughing

Chronic coughing often develops in the late stages of congestive heart failure due to fluid buildup in the lungs. It may produce mucus and is typically worse when lying down.

Swelling

Swelling, also known as edema, is common in the later stages of heart failure and occurs when fluid builds up due to the heart’s reduced pumping ability. This can become much worse in the end stage, and may occur in the:

• Hands
• Feet
• Legs
• Abdomen
• Neck 

Fatigue & Physical Decline

Advanced heart failure patients are typically fatigued. Even minimal activity makes them feel tired and worn out. This is accompanied by an overall physical decline. It becomes increasingly challenging to be active. Even small daily tasks, like bathing or dressing, are very tiring. 

Nausea & Decreased Appetite

As the heart loses function, less blood gets to the abdomen, which slows digestion. Swelling in the abdomen can make the patient feel full. Both of these issues lead to nausea and a decrease in appetite. Even so, many patients experience weight gain rather than weight loss in late stage heart failure due to edema. 

Changes In Heart Rate

Many patients in the late stage of chronic heart failure experience a racing heartbeat, irregular heartbeat, or heart palpitations. The heart is trying to work harder to get more blood out to the rest of the body, resulting in these changes in heartbeat that can be distressing and uncomfortable. 

Difficulty Sleeping

Despite being tired and fatigued, many advanced heart failure patients struggle to sleep. Lying down worsens the effects of fluid buildup in the lungs. Breathlessness and coughing are often more pronounced in this position, making it difficult to fall asleep or stay asleep. Many patients get some relief from sleeping propped up on pillows or even sitting upright. 

Cognitive Changes

End stage heart failure results in low blood flow, low oxygen levels, and sodium imbalances, all of which can affect brain function. Patients may show signs of confusion or disorientation and often experience memory loss. These symptoms can be distressing for both the patient and their caregivers. 

Mood Changes

Mood also tends to change for the worse during the late stages of heart failure. The toll of the disease can lead to anxiety, depression, and other mental health symptoms. These symptoms may be new or may worsen as the disease progresses.

Final Symptoms

When someone is in the very late stages of heart failure, their body slows significantly. They may have just days of life expectancy. Patients at this stage show some characteristic signs: 

• Pale and cold skin
• Breathing changes, including shallow or gurgling breaths and pauses between breaths
• Minimal or no response to touch or voices
• Inability to control bodily functions
• A glazed expression in the yes
• Sudden stillness or silence

How To Manage End Stage Heart Failure Symptoms

Palliative care is an important way to help your loved one get relief from symptoms and live more comfortably with advanced heart failure. There are many surgical treatments for heart failure, which can slow the progression of the disease and help the heart function better, such as implanting a ventricular assist device. 

Many patients don’t want and do not benefit from more aggressive treatments at this point. Palliative care allows them to receive treatments consistent with their wishes and needs. Talk to your loved one’s medical team about their specific symptoms, changes in symptoms, and appropriate treatments. 

Below are some of the typical ways physicians help patients manage end stage heart failure symptoms. 

• Several medications can be helpful for advanced heart failure patients. These include medications to lower blood pressure, diuretics to expel fluids and reduce edema, nitrates to reduce chest pains and dyspnea, and pain-relieving medications. It’s important to work with your loved one’s physicians to find medications that provide relief without introducing too many side effects. 
• Supplemental oxygen can help patients with few side effects. This introduces more oxygen to the body to improve daily functioning, reduce shortness of breath, and reduce fatigue and tiredness. 
• Dietary changes can help relieve specific symptoms, like edema. Fluid retention is affected by foods and beverages, particularly by sodium intake. A heart healthy, low-sodium diet and reduced fluid intake can help manage swelling. 
• Therapy and mental health support are also very helpful. Most patients experience changes in mood and cognitive function. Mental health care can help patients and their caregivers better cope with the difficulties associated with this disease. 

What Is The Life Expectancy For End Stage Heart Failure? 

Unfortunately, end stage chronic heart failure is terminal. Patients don’t recover from this condition. Once a patient has reached the end stage, life expectancy is somewhere between six and twelve months. At the six-month point, many patients are good candidates for hospice care, which may include home health care or inpatient care at a hospice facility. 

Chronic heart failure ultimately leads to end stage or advanced heart failure. As a caregiver of a patient with this condition, it’s important to know and recognize the signs of this late stage. This will help you:

• Provide better care
• Make them more comfortable
• Advocate for palliative treatment or hospice care
