Surgery For Heart Failure: Treatment and Rehabilitation

Effective Treatment: Surgery For Heart Failure Explained

Introduction

Heart failure also known as congestive heart failure, is a condition that commonly affects 750,000 people in Canada, significantly impacting their quality of life. It happens when the heart can’t pump enough blood to meet the body’s needs. The journey of managing heart failure is complex. It requires a comprehensive approach, including lifestyle changes, medication, and in some cases, surgery. Over the years, heart surgery for heart failure has significantly evolved, offering renewed hope and markedly improved outcomes for those affected. 

In this comprehensive blog, we will delve into the complexities of heart failure surgery, exploring a range of treatment options and the important role of rehabilitation in patient recovery.

What is Heart Failure Surgery?

Heart failure surgery is a collective term for a range of medical procedures designed to address the root causes of heart failure and improve the affected heart’s functioning.

Causes of Heart Failure

Understanding the causes of heart failure is important in preventing the condition and tailoring treatment for those already affected. Heart failure can result from various factors, often involving multiple systems within the body.

Coronary Artery Disease

Coronary artery disease (CAD) is the most common cause of heart failure. It occurs when the major blood vessels that supply the heart with blood, oxygen, and nutrients (coronary arteries) become damaged or diseased. Cholesterol-containing deposits (plaque buildup) and inflammation are usually to blame. As these arteries narrow, the heart can’t get enough oxygen-rich blood, leading to weakened heart muscle and, eventually, heart failure.

Hypertension

High blood pressure (hypertension) forces the heart to work harder than normal to circulate blood throughout the body. Over time, this increased workload can make the heart muscle thick and stiff, reducing its effectiveness and leading to heart failure.

Cardiomyopathy

Cardiomyopathy is a condition where the heart muscle becomes enlarged, thicker, or stiffer than normal. In some cases, scar tissue replaces the muscle tissue, impairing the heart’s ability to deliver blood to the body. Cardiomyopathy can happen due to long-term high blood pressure, damage from past heart attacks, chronic rapid heart rate, genetic conditions, and other factors.

Valve Disorders

Heart valves regulate blood flow through the heart by opening and closing to allow blood to move in only one direction. If valves are damaged by conditions such as rheumatic fever, infections, or connective tissue disorders, they may not function properly. This malfunction can lead to heart failure by causing the heart to work harder to pump the same amount of blood or by allowing blood to flow backward, leading to congestion and fluid buildup. According to research, valve disorders are one of the most common causes of congestive heart failure, accounting for 4.3% of cases.

Arrhythmias

Arrhythmias, or irregular heartbeats, can lead to heart failure by causing an abnormal heart rhythm. Tachycardia, where the heart beats too fast, can weaken the heart muscle over time, while bradycardia, where the heart beats too slowly, may prevent the heart from pumping enough blood to meet the body’s needs.

Obesity and Diabetes

Obesity and diabetes greatly increase the risk of heart failure. Excess body weight puts additional strain on the heart, while diabetes increases the risk of high blood pressure and coronary artery disease. Together, these conditions can significantly accelerate the progression of heart failure.

Alcohol and Substance Use

Excessive use of alcohol and certain substances can lead to heart muscle damage, known as alcoholic cardiomyopathy or toxic cardiomyopathy. This damage impairs the heart’s ability to pump blood effectively, leading to heart failure.

Thyroid Disorders

Hyperthyroidism (too much thyroid hormone) and hypothyroidism (too little thyroid hormone) can lead to heart failure. Hyperthyroidism can cause heart-related symptoms like rapid heart rate and high blood pressure, while hypothyroidism can lead to a slow heart rate and increased fluid buildup around the heart.

Symptoms of Heart Failure

Symptoms of Heart Failure

Recognizing the symptoms of heart failure is very important for early diagnosis and treatment. While these symptoms can vary widely among individuals, some common signs include:

Shortness of Breath

Patients often experience difficulty breathing during physical activities or even while at rest. This is due to fluid buildup in the lungs, making it hard for the lungs to expand fully.

Fatigue and Weakness

As heart failure progresses, the body’s cells receive less oxygen, leading to persistent tiredness and weakness, making everyday activities increasingly challenging.

Swelling in Legs, Ankles, and Feet

Fluid retention, a common heart failure symptom, can lead to swelling in the lower extremities. This condition is known as peripheral edema. This can result in gaining weight and increased urination.

Rapid or Irregular Heartbeat

To compensate for the reduced blood pumping capacity, the heart may beat faster or irregularly. This can manifest as palpitations or a feeling of the heart racing.

Stages of Heart Failure

The New York Heart Association (NYHA) Functional Classification and the American College of Cardiology/American Heart Association (ACC/AHA) Stages of Heart Failure are two widely used systems to classify heart failure.

NYHA Functional Classification

Class I (No limitation of physical activity)

Patients experience no symptoms and no limitations in ordinary physical activity, such as walking or climbing stairs.

Class II (Slight limitation of physical activity)

Patients are comfortable at rest, but ordinary physical activity results in symptoms of heart failure.

Class III (Marked limitation of physical activity)

Patients are comfortable at rest, but less than ordinary activity causes symptoms of heart failure.

Class IV (Unable to carry on any physical activity without discomfort)

Patients experience symptoms of heart failure at rest. Discomfort increases with any physical activity.

ACC/AHA Stages of Heart Failure

Stage A

Individuals at high risk for developing heart failure but without structural heart disease or symptoms of heart failure.

Stage B

Individuals with structural heart disease but without signs or symptoms of heart failure.

Stage C

Patients with structural heart disease and symptoms of heart failure.

Stage D

Patients with refractory heart failure requiring specialized interventions.

Determining the Need for Surgery

When is Heart Failure Surgery or Cardiac Surgery Needed?

The decision to proceed with congestive heart failure surgery is based on a comprehensive evaluation of the patient’s condition, including the severity of symptoms, the stage of heart failure, the underlying cause, and the overall health of the patient. Cardiac surgery is considered when medical therapy and lifestyle changes are not enough to manage the symptoms or when the heart failure is at a stage where it could lead to other serious health problems. 

Factors such as age, the presence of other medical conditions, and the potential benefits and risks of surgery are also taken into account. Cardiologists and cardiac surgeons work closely to assess the patient’s condition and determine the most appropriate surgical intervention.

Exploring Types of Heart Failure Surgery

Several surgical procedures can be performed to treat heart failure, each targeting specific causes or symptoms of the condition.

Coronary Artery Bypass Grafting (CABG)

Coronary artery bypass graft is a minimally invasive procedure used to treat coronary artery disease, a common cause of heart failure. It involves taking a healthy blood vessel from another part of the body and using it to reroute blood around a blocked artery in the heart. This makes it easier for blood flow to the heart muscle, reducing symptoms of heart failure.

Valve Repair or Replacement

Faulty heart valves can lead to heart failure by making the heart pump blood harder. Valve repair or heart valve surgery corrects this issue, either by repairing the existing valve or replacing it with an artificial valve.

Cardiac Resynchronization Therapy (CRT) Device Implantation

CRT is a treatment for heart failure in patients whose hearts’ ventricles are not beating in sync. A CRT device, a type of pacemaker, helps coordinate the heart’s rhythm, improving its efficiency and the symptoms of heart failure.

Left Ventricular Assist Device (LVAD) Implantation

An LVAD is a mechanical pump implanted inside a person’s chest, where it helps the heart pump blood throughout the body. It is used in patients with severe heart failure, either as a bridge to heart transplantation or as a destination therapy (long-term treatment).

Total Artificial Heart (TAH) Implantation

A TAH replaces the two lower chambers of the heart (the ventricles) with a device that pumps blood when a patient’s heart is too damaged to do the job itself. It is typically used as a temporary solution until a heart transplant can be performed.

Heart Transplantation

When other treatments don’t work for end-stage heart failure, a heart transplant might be the only option. This critical surgical procedure involves replacing the failing heart with a healthy donor heart, typically sourced from a deceased donor. 

Navigating Post-surgical Care and Rehabilitation

Navigating Post-surgical Care and Rehabilitation

After undergoing surgery for heart failure, comprehensive post-surgical care and rehabilitation are crucial for recovery and improving the patient’s quality of life.

Immediate Post-operative Care

This phase involves close monitoring in the Intensive Care Unit (ICU) of a hospital setting to manage pain, prevent infections, and monitor heart function. The medical team provides support to ensure a smooth recovery process.

Long-term Follow-up and Monitoring

Regular follow-up visits with the health care team are important to monitor the patient’s progress, adjust medications, and address any complications or concerns that may arise.

Rehabilitation Programs

Cardiac rehabilitation is a key part of recovery, involving structured exercise programs, education on heart-healthy living, and counseling to help patients adjust to their new lifestyle and manage their heart condition.

Lifestyle and Dietary Adjustments Post-surgery

Patients are advised to adopt a heart-healthy lifestyle, including a balanced diet, regular physical activity, quitting smoking, and managing stress, to enhance their recovery and overall heart health.

Challenges & Considerations in Surgical Treatment

Risks and Complications of Surgery

Like all surgeries, heart failure surgery comes with risks, including infection, bleeding, blood clots, and complications related to anesthesia. The specific risks depend on the type of surgery and the patient’s overall health.
