About 26 million people worldwide deal with congestive heart failure (CHF). This shows how common and serious this condition is¹. It affects healthcare costs, how well people can function, and their quality of life. It’s important to understand CHF to manage it well.

CHF happens when the heart can’t pump blood well. This leads to fluid buildup in the lungs and other areas. People with CHF often feel tired, have trouble breathing, and can’t do as much physical activity².

HFpEF, a type of CHF, affects 44% to 72% of cases¹. This shows the big challenge it poses to healthcare and the need for special treatments.

Ischemic heart disease is the top cause of death worldwide and a big factor in CHF¹. Other factors like high blood pressure, being older, being female, and having diabetes also play a role. This shows how complex CHF is and why we need to tackle its many risk factors.

What is Congestive Heart Failure?

Definition and Overview

Congestive heart failure (CHF) is a long-term condition where the heart can’t pump blood well³. This leads to fluid buildup in the lungs, legs, and other parts of the body, causing symptoms³. It’s a complex issue that can come from heart problems like coronary artery disease, high blood pressure, and heart valve issues⁴.

Coronary artery disease is the top cause of heart failure, happening when fatty deposits block the arteries and reduce blood flow, possibly causing a heart attack⁴. High blood pressure makes the heart work too hard, making it stiff or weak over time⁴. If heart valve problems aren’t treated, the heart has to work harder, which can weaken it⁴.

Heart failure often starts in the left ventricle but can affect both sides of the heart⁵. It can cause fluid to gather in the belly, legs, and feet, leading to swelling⁵. On the other hand, it can also cause fluid in the lungs, making breathing short⁵.

There are different types of congestive heart failure, like heart failure with reduced ejection fraction (HFrEF), where the left ventricle can’t pump enough blood⁵. Another type is heart failure with preserved ejection fraction (HFpEF), where the left ventricle has trouble filling with blood⁵.

Congestive heart failure is a serious issue that needs quick medical help³. While there’s no cure, many people can manage it with medicine and a healthy lifestyle³.

Symptoms of Congestive Heart Failure

Congestive heart failure (CHF) shows many symptoms, with how bad they are depends on the stage and cause. Shortness of breath, fatigue, and swelling in the legs and feet are common signs of CHF⁶. People might also feel a rapid or irregular heartbeat, reduced exercise tolerance, wheezing, persistent coughing or wheezing, nausea and loss of appetite, and confusion or reduced alertness⁶.

CHF’s symptoms can start slowly and might not be noticed at first⁷. As it gets worse, the symptoms become clearer, and you should see a doctor fast⁶⁷.

• Shortness of breath, especially during physical activity or when lying down⁶⁸
• Persistent fatigue and weakness⁶
• Swelling in the legs, ankles, and feet⁶⁸
• Rapid or irregular heartbeat⁶
• Persistent coughing or wheezing⁶⁸
• Nausea, loss of appetite, and unintentional weight loss⁶
• Confusion, memory issues, and reduced alertness⁶

If symptoms get worse or new ones show up, get medical help right away. This could mean your heart is getting worse and you need treatment fast⁸.

“Recognizing the signs and symptoms of congestive heart failure is crucial for early diagnosis and effective management of the condition.”⁶⁷⁸

Causes and Risk Factors

Congestive heart failure is a complex condition with many causes and risk factors. Knowing what causes it is key to preventing and managing it. This chronic disease has many underlying heart conditions and risk factors.

Heart Conditions Leading to Heart Failure

Common causes include coronary artery disease, high blood pressure, heart valve issues, and cardiomyopathy⁹. Coronary artery disease can lead to heart attacks and damage the heart muscle, making heart failure more likely¹⁰. High blood pressure also strains the heart, making it work too hard and eventually fail¹¹.

Heart valve problems, like aortic valve stenosis, add to the heart’s strain and can cause heart failure¹¹. Cardiomyopathy directly affects the heart muscle, making it less able to pump blood, leading to heart failure.

Other Contributing Factors

Other factors can also raise the risk of congestive heart failure¹⁰. Lifestyle choices like smoking, being overweight, and not being active can increase the risk¹⁰. Medical conditions such as diabetes, thyroid disorders, and arrhythmias can also lead to heart failure¹⁰.

Some medicines, like Adriamycin (doxorubicin), can harm the heart and raise the risk of heart failure¹¹.

It’s important to find and treat the cause of congestive heart failure for effective management. By understanding the different causes, doctors can create better treatment plans to help patients.

“Congestive heart failure is a complex and multifaceted condition, with a wide range of potential underlying causes. Addressing the root causes is essential for effective disease management and improving the quality of life for those affected.”

⁹¹⁰¹¹

Stages of Congestive Heart Failure

Congestive heart failure is a condition that gets worse over time. Knowing its stages is key to managing and treating it. The American College of Cardiology (ACC) and the American Heart Association (AHA) have set up four stages. These stages go from having no symptoms to severe symptoms¹².

ACC/AHA Heart Failure Stages

1. Stage A: This is the first stage. People at risk of getting heart failure are here. They might have conditions like high blood pressure, diabetes, or obesity but don’t show symptoms yet¹².
2. Stage B: Here, the heart has changed but doesn’t cause symptoms. Treatment focuses on fixing the heart and stopping the condition from getting worse¹².
3. Stage C: This stage has symptoms like shortness of breath, feeling tired, and swelling. Treatment helps manage these symptoms and educates on heart failure¹².
4. Stage D: This is the most severe stage with severe symptoms. It might need treatments like heart transplant, LVADs, or palliative care. People at this stage usually live only 6 to 12 months¹².

Going from stage A to D means life expectancy gets shorter. Stages A and B have a longer life expectancy, but stage D is much shorter¹².

The New York Heart Association (NYHA) also has four classes for heart failure. These classes are based on how well the heart pumps. But, some researchers question how useful these classes are for heart failure¹².

Living a healthy life, staying active, eating well, and managing health conditions can help prevent or slow heart failure¹³.

Types of Congestive Heart Failure

Congestive heart failure can be classified by the heart’s ejection fraction (EF). This measures how much blood the heart pumps out with each beat¹⁴. There are three main types: heart failure with reduced ejection fraction (HFrEF), heart failure with mildly reduced ejection fraction, and heart failure with preserved ejection fraction (HFpEF). Each type needs its own treatment plan.

Classification Based on Ejection Fraction

Heart failure with reduced ejection fraction means the heart can’t pump well because it’s weak¹⁴. Doctors can tell if it’s mildly or severely reduced¹⁴. The most common type is left-sided heart failure, often caused by heart disease, a heart attack, or high blood pressure¹⁴.

On the other hand, HFpEF happens when the heart muscle gets stiff, making it hard for the ventricles to fill with blood¹⁴. Right-sided heart failure can come from severe left-sided heart failure, high blood pressure in the lungs, or lung diseases like COPD¹⁴. Biventricular heart failure affects both sides of the heart, causing symptoms of both left and right heart failure¹⁴.

Chronic heart failure often starts slowly from ongoing health issues like high blood pressure. Acute heart failure can happen suddenly after a big heart attack or heart rhythm problems¹⁴.

Type of Heart Failure	Characteristics
Heart Failure with Reduced Ejection Fraction (HFrEF)	Weaker pumping ability of the heart, also known as systolic failure14
Heart Failure with Preserved Ejection Fraction (HFpEF)	Stiffer heart muscle, making it more difficult for the ventricles to fill with blood14
Right-Sided Heart Failure	Develops as a result of advanced left-sided heart failure, caused by high blood pressure in the lungs, pulmonary embolism, or lung diseases14
Biventricular Heart Failure	Both sides of the heart are affected, leading to symptoms of both left-sided and right-sided heart failure14

The main way to classify congestive heart failure is by the heart’s ejection fraction and which chambers are affected¹⁴. Knowing this helps doctors choose the right treatment for each patient¹⁴.

Congestive Heart Failure and the Heart’s Chambers

Congestive heart failure (CHF) is a complex condition that affects the heart’s ability to fill with blood or pump it to the body¹⁵. It can affect the right or left side of the heart, or both¹⁶. Knowing how CHF affects the heart’s chambers is key for diagnosis and treatment.

In left-sided heart failure, the left ventricle can’t pump enough oxygenated blood to the body¹⁷. This means it can’t push out as much blood as it should, with less than 55-65% being ejected¹⁷. Diastolic heart failure happens when the left ventricle can’t fill properly, making it stiff and less flexible¹⁷.

Right-sided heart failure often comes from left-sided failure, causing blood to back up in the veins¹⁶. This can lead to swelling and fluid buildup, known as congestive heart failure¹⁶. Sometimes, right-sided failure can happen on its own, usually from lung or pulmonary issues¹⁷.

Biventricular heart failure is the most severe type, affecting both the left and right ventricles¹⁷.

Healthcare providers need to know which chambers and valves are affected by CHF to create the right treatment plan¹⁶. This might include lifestyle changes, medication, surgery, or device therapies, based on the condition’s severity and causes¹⁶.

Heart Failure Type	Description	Affected Chambers
Left-sided Heart Failure	Reduced ability of the left ventricle to pump blood effectively	Left ventricle
Right-sided Heart Failure	Reduced ability of the right ventricle to pump blood effectively	Right ventricle
Biventricular Heart Failure	Reduced ability of both the left and right ventricles to pump blood effectively	Both left and right ventricles

Understanding how CHF affects the heart’s chambers helps doctors create tailored treatments¹⁶¹⁵¹⁷. This approach can improve outcomes and quality of life for those with this chronic condition.

Diagnosis and Testing

Diagnosing congestive heart failure (CHF) is a detailed process. It includes a full medical check-up, a detailed history, and various tests. These tests are key in finding out how severe the heart failure is, what causes it, and what treatment is needed¹⁸.

Diagnostic Tests for Heart Failure

The echocardiogram is a main tool for checking heart failure. It’s a test that uses sound waves to make pictures of the heart. This lets doctors see how well the heart is pumping, known as the ejection fraction¹⁹. A good ejection fraction is 50% or higher for diagnosing heart failure¹⁹.

Doctors might also use an electrocardiogram (EKG or ECG) to check the heart’s electrical activity. This test helps spot heart rhythm problems or past heart attacks²⁰. Blood tests for cardiac biomarkers can also help diagnose and track heart failure¹⁸.

For a deeper look, doctors might suggest imaging tests like a chest X-ray, CT scan, or MRI. These tests show the heart and its surroundings. They give clues about the heart’s size, shape, and any other issues that might be causing heart failure¹⁸.

Sometimes, doctors will order a cardiac catheterization. This involves putting a thin tube into a blood vessel and guiding it to the heart. It lets doctors directly check the heart’s function and the arteries around it²⁰.

By using these tests together, doctors can fully understand the patient’s condition. They can then make a treatment plan that works best for managing congestive heart failure¹⁸.

“Diagnosing congestive heart failure is a comprehensive process that involves a variety of tests to evaluate the heart’s structure, function, and underlying causes.”

Congestive Heart Failure Management

Managing congestive heart failure (CHF) involves many steps. These include using medicines, changing lifestyles, and sometimes surgery or devices²¹. Doctors create a plan based on the patient’s specific needs and health status.

Treatment Approaches

Medicines are a key part of treating CHF. Doctors often prescribe vasodilators, diuretics, ACE inhibitors, and beta-blockers²¹. These drugs help the heart work better, ease symptoms, and prevent more problems. For severe cases, surgery like opening blocked arteries or replacing heart valves might be needed²¹.

New treatments like biventricular pacing therapy and implantable cardioverter defibrillators also help manage heart failure²¹. For those with severe heart failure, a heart transplant is an option. About 88% of these transplants succeed after one year, and 75% after five years²¹.

Changing your lifestyle is also important. Quitting smoking, eating right, and staying active can prevent and manage CHF²¹. These changes help control conditions like high blood pressure and diabetes, which can lead to heart failure²¹.

Scientists have found a protein that can predict if a patient will be readmitted to the hospital for CHF. This discovery could lead to better treatments²¹.

Handling CHF is a detailed process. Doctors and patients work together to find the best treatment plan. By using medicines, making lifestyle changes, and trying new therapies, people with CHF can live better lives²¹.

Congestive Heart Failure Medications

Medications are key in managing congestive heart failure (CHF). People with heart failure often take a mix of drugs. These help improve symptoms, slow disease progression, and lower the risk of complications²².

Common medications for CHF include diuretics, ACE inhibitors, ARBs, beta-blockers, and mineralocorticoid receptor antagonists²². Each type of medication supports the heart and reduces the strain on the cardiovascular system.

Diuretics, like furosemide (Lasix) and hydrochlorothiazide (HCTZ), help remove excess fluids. This reduces the heart’s workload²³. ACE inhibitors and ARBs, including lisinopril (Prinivil, Zestril) and losartan (Cozaar), lower blood pressure and widen blood vessels. This makes it easier for the heart to pump blood²³. Beta-blockers, such as carvedilol (Coreg) and metoprolol succinate (Toprol XL), improve heart function by blocking certain hormones that strain the heart²³.

Mineralocorticoid receptor antagonists, like spironolactone (Aldactone) and eplerenone (Inspra), reduce fluid buildup and improve heart function²³. Other drugs, such as digoxin, anticoagulants, and cholesterol-lowering medications, may also be prescribed for specific CHF aspects²³.

Each medication can have side effects, so healthcare providers work closely with patients to find the best treatment plan²². Regular checks and adjustments to medications are key for managing CHF and improving health outcomes.

Medication Class	Medication Goal	Commonly Prescribed Medications
ACE Inhibitors and ARBs	Lower blood pressure, widen blood vessels, reduce heart workload	Lisinopril (Prinivil, Zestril), Enalapril (Vasotec), Losartan (Cozaar), Valsartan (Diovan)
ARNIs	Improve artery opening, blood flow, reduce sodium retention	Sacubitril/valsartan (Entresto)
If Channel Blockers	Reduce heart rate	Ivabradine (Corlanor)
Beta Blockers	Beta-adrenergic blocking agents, improve heart function	Carvedilol (Coreg), Metoprolol succinate (Toprol XL), Propranolol (Inderal)
SGLT-2 Inhibitors	Improve blood glucose, weight control, decrease blood pressure	Empagliflozin (Jardiance), Dapagliflozin (Farxiga)
Aldosterone Antagonists	Reduce fluid buildup, improve heart function	Spironolactone (Aldactone), Eplerenone (Inspra)
Vasodilators	Widen blood vessels, improve blood flow	Hydralazine, Isosorbide dinitrate (Bidil)
Diuretics	Rid body of excess fluids, relieve heart’s workload	Furosemide (Lasix), Hydrochlorothiazide (HCTZ)
Other Medications	–	Anticoagulants, Cholesterol-lowering drugs, Digoxin

Congestive heart failure is complex, and managing medications is vital. By working with healthcare providers, patients can find the right medications. These help manage symptoms, slow disease progression, and improve life quality.

Lifestyle Changes for Congestive Heart Failure

Making lifestyle changes is key to managing congestive heart failure. By changing your diet, exercise, and health habits, you can improve your life and slow the disease’s progress²⁴²⁵.

Dietary Modifications

For those with congestive heart failure, eating right is crucial. NYU Langone heart experts suggest cutting sodium to 2,000 to 3,000 milligrams daily to reduce swelling²⁴. Focus on fruits, veggies, whole grains, and lean proteins, and limit bad fats and sodium to manage symptoms and boost health²⁶.

Exercise and Physical Activity

Exercise is great for those with congestive heart failure. Daily light workouts are safe and can ease symptoms, lowering heart rate and blood pressure²⁴. Cardiac rehab teams can create exercise plans that are safe and effective²⁵.

Managing Other Health Conditions

Handling other health issues is vital for managing congestive heart failure. High blood pressure can make heart failure worse, so keeping it under control is key²⁴. Diabetes increases the risk of heart problems, so keeping blood sugar in check is crucial²⁴.

Lifestyle Factors

Some lifestyle choices affect heart failure management. Smoking harms heart health, and NYU Langone offers Tobacco Cessation Programs to help quit²⁴. Drinking too much alcohol raises the risk of heart failure, so it’s best to limit it²⁵. Managing stress is also important, and NYU Langone offers stress-reducing services through Integrative Health Services²⁴.

By making these lifestyle changes, people with congestive heart failure can take charge of their health and quality of life²⁵. Regular check-ins with doctors are important to make sure these changes work well²⁶.

Living with Congestive Heart Failure
