Heart Failure



Heart failure, sometimes known as congestive heart failure, occurs when your heart muscle doesn't pump blood as well as it should. Certain conditions, such as narrowed arteries in your heart (coronary artery disease) or high blood pressure, gradually leave your heart too weak or stiff to fill and pump efficiently.

 Not all conditions that lead to heart failure can be reversed, but treatments can improve the signs and symptoms of heart failure and help you live longer. Lifestyle changes — such as exercising, reducing salt in your diet, managing stress and losing weight — can improve your quality of life.
 

What Is Heart Failure

Heart failure does not mean the heart has stopped working. Rather, it means that the heart's pumping power is weaker than normal. With heart failure, blood moves through the heart and body at a slower rate, and pressure in the heart increases. As a result, the heart cannot pump enough oxygen and nutrients to meet the body's needs. The chambers of the heart may respond by stretching to hold more blood to pump through the body or by becoming stiff and thickened. This helps to keep the blood moving, but the heart muscle walls may eventually weaken and become unable to pump as efficiently. As a result, the kidneys may respond by causing the body to retain fluid (water) and salt. If fluid builds up in the arms, legs, ankles, feet, lungs, or other organs, the body becomes congested, and congestive heart failure is the term used to describe the condition. 
What Causes Heart Failure


Heart failure is caused by many conditions that damage the heart muscle, including:Coronary artery disease. Coronary artery disease (CAD), a disease of the arteries that supply blood and oxygen to the heart, causes decreased blood flow to the heart muscle. If the arteries become blocked or severely narrowed, the heart becomes starved for oxygen and nutrients.Heart attack. A heart attack occurs when a coronary artery becomes suddenly blocked, stopping the flow of blood to the heart muscle. A heart attack damages the heart muscle, resulting in a scarred area that does not function properly.Cardiomyopathy. Damage to the heart muscle from causes other than artery or blood flow problems, such as from infections or alcohol or drug abuse.Conditions that overwork the heart. Conditions including high blood pressure, valve disease, thyroid disease, kidney disease, diabetes, or heart defects present at birth can all cause heart failure. In addition, heart failure can occur when several diseases or conditions are present at once.Heart Disease and Congestive Heart FailureYou may not have any symptoms of heart failure, or the symptoms may be mild to severe. Symptoms can be constant or can come and go. The symptoms can include:
SYMPTOMS OF HEART FAILURE


Congested lungs. Fluid backup in the lungs can cause shortness of breath with exercise or difficulty breathing at rest or when lying flat in bed. Lung congestion can also cause a dry, hacking cough or wheezing.Fluid and water retention. Less blood to your kidneys causes fluid and water retention, resulting in swollen ankles, legs, abdomen (called edema), and weight gain. Symptoms may cause an increased need to urinate during the night. Bloating in your stomach may cause a loss of appetite or nausea.Dizziness, fatigue, and weakness. Less blood to your major organs and muscles makes you feel tired and weak. Less blood to the brain can cause dizziness or confusion.Rapid or irregular heartbeats. The heart beats faster to pump enough blood to the body. This can cause a rapid or irregular heartbeat.If you have heart failure, you may have one or all of these symptoms or you may have none of them. They may or may not indicate a weakened heart.What Are the Types of Heart Failure?Systolic dysfunction (or systolic heart failure) occurs when the heart muscle doesn't contract with enough force, so there is less oxygen-rich blood that is pumped throughout the body.Diastolic dysfunction (or diastolic heart failure) occurs when the heart contracts normally, but the ventricles do not relax properly or are stiff, and less blood enters the heart during normal filling.A calculation done during an echocardiogram, called the ejection fraction (EF), is used to measure how well your heart pumps with each beat to help determine if systolic or diastolic dysfunction is present. Your doctor can discuss which condition you have.Is There a Treatment for Heart Failure?There are more treatment options available for heart failure than ever before. Tight control over your medications and lifestyle, coupled with careful monitoring, are the first steps. As the condition progresses, doctors specializing in the treatment of heart failure can offer more advanced treatment options.
Treatment Options Includes:
  1.       Diet
  2.       Lifestyle & Modification
  3.       Stop Smoking
  4.       Treat High Blood Pressure
  5.       Drugs
  6.       Surgical Options
  7.       Device Therapy
The goals of treating heart failure are primarily to decrease the likelihood of disease progression (thereby decreasing the risk of death and the need for hospitalization), to lessen symptoms, and to improve quality of life.Together, you and your doctor can determine the best course of treatment for you
How Can I Prevent Heart Failure From Worsening


Keep your blood pressure low. In heart failure, the release of hormones causes the blood vessels to constrict or tighten. The heart must work hard to pump blood through the constricted vessels. It is important to keep your blood pressure controlled so that your heart can pump more effectively without extra stress.Monitor your own symptoms. Check for changes in your fluid status by weighing yourself daily and checking for swelling. Call your doctor if you have unexplained weight gain or if you have increased swelling.Maintain fluid balance. Your doctor may ask you to keep a record of the amount of fluids you drink or eat and how often you go to the bathroom. Remember, the more fluid you carry in your blood vessels, the harder your heart must work to pump excess fluid through your body. Limiting your fluid intake to less than 1.5 liters per day will help decrease the workload of your heart and prevent symptoms from recurring.Limit how much salt (sodium) you eat. Sodium is found naturally in many foods we eat. It is also added for flavoring or to make food last longer. If you follow a low-sodium diet, you should have less fluid retention, less swelling, and breathe easier.Monitor your weight and lose weight if needed. Weigh yourself at the same time each day, preferably in the morning, in similar clothing, after urinating but before eating, and on the same scale. Record your weight in a diary or calendar. Your doctor may want to adjust your medications.Monitor your symptoms. Call your doctor if new symptoms occur or if your symptoms worsen. Do not wait for your symptoms to become so severe that you need to seek emergency treatment.Take your medications as prescribed. Medications are used to improve your heart's ability to pump blood, decrease stress on your heart, decrease the progression of heart failure, and prevent fluid retention. Many heart failure drugs are used to decrease the release of harmful hormones. These drugs will cause your blood vessels to dilate or relax (thereby lowering your blood pressure).Schedule regular doctor appointments. During follow-up visits, your doctors will make sure you are staying healthy and that your heart failure is not getting worse. Your doctor will ask to review your weight record and list of medications. If you have questions, write them down and bring them to your appointment. Call your doctor if you have urgent questions. Notify all your doctors about your heart failure, medications, and any restrictions. Also, check with your heart doctor about any new medications prescribed by another doctor. Keep good records and bring them with you to each doctor visit.
How Can I Prevent Further Heart Damage

In an effort to prevent further heart damage:Stop smoking or chewing tobacco.Reach and maintain your healthy weight.Control high blood pressure, cholesterol levels, and diabetes.Exercise regularly.Do not drink alcohol.Have surgery or other procedures to treat your heart failure as recommended.It is important to know the names of your medications, what they are used for, and how often and at what times you take them. Keep a list of your medications and bring them with you to each of your doctor visits. Never stop taking your medications without discussing it with your doctor. Even if you have no symptoms, your medications decrease the work of your heart so that it can pump more effectively.
How Can I Improve My Quality of Life With Heart Failure


There are several things you can do to improve your quality of life if you have heart failure. Among them:Eat a healthy diet. Limit your consumption of sodium (salt) to less than 2,000 milligrams (2 grams) each day. Eat foods high in fiber. Limit foods high in trans fat, cholesterol, and sugar. Reduce total daily intake of calories to lose weight if necessary.Exercise regularly. A regular cardiovascular exercise program, prescribed by your doctor, will help improve your strength and make you feel better. It may also decrease heart failure progression.Don't overdo it. Plan your activities and include rest periods during the day. Certain activities, such as pushing or pulling heavy objects and shoveling may worsen heart failure and its symptoms.Prevent respiratory infections. Ask your doctor about flu and pneumonia vaccines.Take your medications as prescribed. Do not stop taking them without first contacting your doctor.
Can Surgery Be Used to Treat Heart Failure


In heart failure, surgery may sometimes prevent further damage to the heart and improve the heart's function. Procedures used include:Coronary artery bypass grafting surgery. The most common surgery for heart failure caused by coronary artery disease is bypass surgery. Although surgery is more risky for people with heart failure, new strategies before, during, and after surgery have reduced the risks and improved outcomes.Heart valve surgery. 
Diseased heart valves can be treated both surgically (traditional heart valve surgery) and non-surgically (balloon valvuloplasty).Implantable left ventricular assist device (LVAD). The LVAD is known as the "bridge to transplantation" for patients who haven't responded to other treatments and are hospitalized with severe systolic heart failure. This device helps your heart pump blood throughout your body. It allows you to be mobile, sometimes returning home to await a heart transplant. It may also be used as destination therapy for long-term support in patients who are not eligible for transplant.Heart transplant. A heart transplant is considered when heart failure is so severe that it does not respond to all other therapies, but the person's health is otherwise good.

AUTOMATIC IMPLANTABLE CARDIOVERTER DEFIBRILLATORS (AICD)

           Automatic Implantable Cardioverter Defibrillators (AICD)                                                              Why is the doctor performing this PROCEDURE? To monitor an abnormally beating heart, either one that beats too fast (Tachycardia), too slow (Brachycardia) or irregularly irregular (Atrial Fibrillation). These abnormal heart beats are referred to as arrhythmias.  What is an AICD? An AICD is a device that monitors a person's heart rate. They are generally implanted into heart failure patients. The device is programmed to perform the following tasks: speed up or slow down your heart, depending upon the heart rate. The AICD gives your heart a shock if you start having life threatening arrhythmias or an abnormally high heart rate. Arrhythmias occur ...
