Congestive heart failure occurs when the heart isn’t pumping blood as efficiently as it should. As a result, the flow of blood to the vital organs decreases and causes the pressures in the heart to increase. This prevents the heart from pumping enough blood that supplies the oxygen and nutrients to meet the body’s needs. Congestive heart failure can be caused by a number of conditions that damage the heart muscle, such as coronary artery disease, heart attack, cardiomyopathy, and high blood pressure.
Heart failure when associated with congestion or fluid retention is referred to as congestive heart failure. The fluid retention can be in the lungs (pulmonary congestion or pulmonary edema), legs, ankles, liver (hepatic congestion), or the abdomen (ascites).
Types of heart failure are:
The heart’s left ventricle is the most important chamber that is responsible for delivering blood and oxygen to all organs. When the left ventricle fails, the function of all organs is affected. There are two types of left-sided heart failure:
This occurs when the heart muscle doesn’t contract with enough force, which leads to less oxygen-rich blood being pumped through the body.
With this condition, the heart contracts normally, but the left ventricle is stiff, causing pressure, inside the heart to rise.
The heart’s right ventricle works to pump blood into the lungs to be filled with oxygen. During right-sided heart failure, the right ventricle loses its ability to pump. This causes the blood to back up into the veins. Right-sided heart failure typically results in fluid retention and swollen feet, ankles, and legs.
Acute heart failure, also referred to as decompensated heart failure, is a life-threatening condition with rapidly developing symptoms that require immediate medical care. With acute heart failure, the heart struggles to deliver enough oxygen to meet the body’s needs.
Cardiogenic shock means that there is sudden, severe loss of heart function that results in dangerously low blood pressures, and inability of the heart to pump enough blood to get oxygen to vital organs and tissues. This condition can result in life-threatening organ dysfunction.
Cardiogenic shock can occur as a result of:
When a patient is in shock, time is of the essence. At AHN, a team of experts specializing in cardiogenic shock will act quickly to:
This process has made huge improvements in helping more patients survive cardiogenic shock.
Some people may not encounter any symptoms of heart failure. Those who do, however, could experience symptoms that are either constant, intermittent, or progressive, including:
Based upon the severity of symptoms, people with congestive heart failure are categorized using the New York Heart Association (NYHA) Functional Classification system. It places people in one of four classes based on how much they are limited during physical activity.
There are no limitations to physical activity. Regular physical activity does not cause fatigue, shortness of breath, or palpitation.
There is slight limitation of physical activity, though the person is comfortable at rest. Regular physical activity results in fatigue, palpitation, or shortness of breath.
There is a noticeable limitation of physical activity, though the person is comfortable at rest. Less than regular activity causes fatigue, palpitation, or shortness of breath.
The person is unable to carry on any physical activity without discomfort, and there are symptoms of heart failure at rest. If any physical activity is undertaken, discomfort increases.
There are also four stages of systolic heart failure. It’s important to note that, typically, heart failure cannot be reversed, and you can only progress to more advanced stages over time, including:
This includes people at high risk for developing systolic heart failure, also referred to as pre-heart failure.
This category involves patients diagnosed with systolic left ventricular dysfunction. At this stage, patients usually aren’t experiencing signs and symptoms of heart failure.
This is classified as patients diagnosed with systolic heart failure who have current or prior symptoms.
This refers to patients diagnosed with systolic heart failure who are experiencing advanced symptoms after receiving medical care.

There isn’t a cure for heart failure. However, doctors at the AHN Cardiovascular Institute are committed to protecting your heart from further damage and minimizing symptoms, so you can enjoy life more fully, live longer, and stay out of the hospital.
Our specialists use the most advanced imaging methods and other diagnostic tools to determine the cause, severity, and nature of your heart failure.
Your physician may order heart testing or heart imaging procedures.
This procedure measures your heart’s electrical activity and shows signs of heart damage, or irregular heartbeat (arrhythmia).
This wearable EKG/ECG device provides continuous measurements of your heart’s electrical activity for up to 30 days.
This exercise test on a treadmill or bicycle measures how your heart responds to exercise and helps diagnose blocked arteries to your heart. It also provides an accurate measure of your functional capacity (oxygen consumption).
Your doctor inserts a flexible tube, or catheter, into a blood vessel, either in your neck, leg, or wrist under X-ray. This is done to locate blockages in the arteries of your heart or to measure the pressures inside your heart, and the amount of blood your heart pumps with each beat.
During cardiac catheterization, your doctor will insert a bioptome or a biopsy catheter to remove a tiny piece of your heart muscle so that we can evaluate what is responsible for damaging your heart.
These images show heart enlargement or damage, as well as fluid retention in your lungs (pulmonary edema) due to heart failure.
This ultrasound procedure measures the size of your heart, pumping action of your heart, also known as ejection fraction, and evaluates how your heart valves are working.
Also called a blood pool scan, this nuclear imaging test uses an injectable radioactive substance (tracer) to measure ejection fraction, or how well your heart pumps blood with each heartbeat.
This nuclear imaging test uses an injectable tracer to evaluate blood flow to the different regions of the heart. This test is often combined with a stress test.
This scan uses radio waves and a magnetic field to create real-time 3D images of your heart’s structure and function. Learn more about cardiovascular imaging.
During a CT scan, an injectable dye reveals blockages in blood vessels that supply blood to your heart. This test can also evaluate calcium deposits in the arteries and valves in your heart.
This nuclear heart scan also uses tracers to display blood flow to your heart and check for heart damage. In addition, this test can also evaluate the metabolic activity of your heart.
This nuclear heart scan also uses a radioactive tracer (PYP) to evaluate for a heart condition called cardiac amyloidosis.
Depending on the severity of your condition, your doctor may recommend one or more of the following:
A number of medications can relieve symptoms, improve heart function, and slow disease progression in heart failure. These medications can also help you live longer with an improved quality of life. Our team will work with you to start and manage all your medications. When appropriate, you may have the opportunity to participate in clinical trials to receive the latest medication treatment for your heart failure. Learn more about cardiovascular research at AHN.
Depending upon how weak your heart is, you may be a candidate for an implantable cardioverter defibrillator (ICD), a cardiac resynchronization therapy (CRT) pacemaker, or both.
You may be a candidate for either a cardiac contractility modulation (CCM) device, or a baroreceptor stimulation (Barostim™) device which can help to improve your heart function and your symptoms.
Once your heart weakens substantially, and you are not responding as well to medical therapy, you may need a ventricular assist device (VAD), or other type of mechanical circulatory support to help your heart function.
This machine pumps your blood outside of your body, oxygenates it, and then returns oxygenated blood back to you. It is sometimes needed as a lifesaving measure when your heart stops or you go into shock. Learn more about ECMO
We offer minimally invasive, catheter-based procedures to treat structural heart disease. These include transcatheter aortic valve replacement (TAVR) and MitraClip® for patients with heart valve disease too ill to undergo traditional surgery. Learn more about heart valve surgery.
Our surgeons use innovative robotic technology to divert blood flow (bypass) around a diseased artery in the heart. The improved blood flow in turn can improve heart function. Find out if robotic and minimally invasive surgery is right for you.
Heart transplantation can be lifesaving in patients with heart failure who are failing all other treatments. Our heart transplant program has some of the best patient survival rates in Pennsylvania, according to the Scientific Registry of Transplant Recipients.
