==Overview==
[[Heart failure]] is a [[clinical]] [[syndrome]] in which the [[heart]] cannot pump enough [[blood]] throughout the [[body]]. It can be caused by many types of [[cardiovascular diseases]], such as [[coronary artery disease]], [[hypertension]], [[diabetes]], [[Valvular heart disease|valve heart diseases]] and [[Endocrine system|endocrine]] diseases. Usual signs and symptoms include [[blood]] and fluid to back up into the [[lungs]], [[edema]] in the [[feet]], [[Ankle-joint|ankles]] and [[legs]], [[Fatigue|tiredness]] and [[shortness of breath]]. Patient's [[symptoms]], [[echocardiogram]] and [[cardiac MRI]] can be evidence to assess the heart function. Treatments include treating the underlying cause of your heart failure, medicines, [[percutaneous coronary intervention]], [[left ventricular assist device]] ([[LVAD]]) and [[heart transplantation]]. The [[prognosis]] of heart failure varies widely. It depends on the cause of [[Congestive heart failure|heart failure]], [[left ventricular]] [[ejection fraction]] and the duration of the disease.

==What are the symptoms of Congestive heart failure?==
*Early cases of heart failure do not have any [[symptoms]].


{{EJ}}
*As the disease develops, people may notice one or more of the following [[symptoms]]:
* [[Ankle edema]] or [[swelling of the feet]] and legs
* [[Claudication]] or [[pain with walking]]
* [[Confusion]] and [[altered mentation]]
* [[Cool extremities]] or [[cold and clammy hands]]
* [[Cyanosis]] or [[bluish color to the skin]]
* [[Dizziness]]
* [[Dyspnea|Dyspnea on ordinary exertion]] or greater shortness of breath with usual activities
* [[Fainting]]
* [[Fatigue]]
* [[Hemoptysis]] or frothy sputum
* [[Nocturia]] or [[urination during the night]]
* [[cough|Nocturnal cough]]
* [[Orthopnea]] or [[sleeping on pillows]]
* [[Palpitation]]s or [[extra heart beats]]
* [[Paroxysmal nocturnal dyspnea]] or [[awakening at night with shortness of breath]]
* [[Shortness of breath]]
* [[Syncope]] or [[passing out]]
* [[Weakness]]
* [[Wheezing]] or cardiac asthma


==What is heart failure?==
*Other health problems may also cause these [[symptoms]]. Only a doctor can tell for sure. A person with any of these [[symptoms]] should tell the doctor so that the problems can be diagnosed and treated as early as possible.


==How do I know if I have heart failure and what are the symptoms of heart failure?==
==What causes Congestive heart failure?==
Early heart failure does not have any symptoms. As the disease developes, people may notice one or more of the following symptoms:
*[[Congestive heart failure|Heart failure]] is a long-term (chronic) condition, but it can sometimes develop suddenly.
:*[[Shortness of breath]] during physical activity
:*Difficulty breathing when lying in a flat position
:*[[Palpitation]]
:*[[Hemoptysis]] or pink frothy sputum
:*Blood and fluid to back up into the lungs
:*[[Edema]] in the feet, ankles and legs
:*[[Tiredness]]
:*Swollen neck (jugular) veins


Other health problems may also cause these symptoms. Only a doctor can tell for sure. A person with any of these symptoms should tell the doctor so that the problems can be diagnosed and treated as early as possible.
*The condition may affect only the right side or only the left side of the [[heart]]. These are called '''right-sided heart failure''' or '''left-sided heart failure'''. More often, both sides of the heart are involved.


==Who is at risk for heart failure?==
*[[Congestive heart failure|Heart failure]] is present when:
Certain factors increase your risk of getting heart disease, then increase your risk of getting heart failure. You are at a higher risk if you are:
:*A woman age 55 or older
:*A man age 45 or older
:*[[Obesity]] or [[overweight]]
:*[[Smoking]]
:*High cholesterol
:*[[High blood pressure]]
:*Heavy drinking
:*[[Diabetes]]
:*Lack of exercise


==How to know you have heart failure?==
:*Your [[heart]] muscle cannot pump (eject) the [[blood]] out of the heart very well. This is called '''[[systolic heart failure]]'''.
:*[[BNP]](Brain natriuretic peptide)/ NT-proBNP (N-terminal pro b-type natriuretic peptide) test: Either [[BNP]] or NT-proBNP may be used to help diagnose heart failure and to grade the severity of that heart failure. Foremore, the levels can help doctors differentiate between heart failure and lung diseases.  
 
:*[[Echocardiogram]]: This is a painless and no risk test for patients. Cardiac echo can demonstrate both structure and function of the heart. It can tell the doctor the left ventricular ejection fraction and help doctor detect the heart function.
:*Your [[heart]] muscles are stiff and do not fill up with [[blood]] easily. This is called '''[[diastolic heart failure]]'''.
:*[[Chest X-ray]]: The test can creat the picture of the heart and lungs. When heart failure appears, the picture may show largened heart and pulmonary venous pleonaemia.
 
:*[[Cardiac MRI]] (magnetic resonance imaging): Cardiac MRI can create both still and moving pictures of the heart and major blood vesselsheart. It can help doctors analyse the structure and function of the heart and decide the treatment protocols for the patient.
*Both of these problems mean the [[heart]] is no longer able to pump enough oxygen-rich blood out to the rest of your body, especially when you exercise or are active.
:*Cardiac biomarkers: This is a blood test. It needs to be done to identify your basic cardiac diseases such as acute coronary syndrome.
 
:*[[Electrocardiogram]]: This is a simple and painless test that records the heart's electrical activity. It also needs to be done to detect your basic cardiac diseases.
*As the [[Heart|heart's]] pumping action is lost, blood may back up in other areas of the body. Fluid builds up in the [[lungs]], [[liver]], [[gastrointestinal tract]], and the arms and legs. This is called [[congestive heart failure]].
:*[[Thoracentesis]]: In heart failure, the pleural space is filled with more fluid than normal and it can cause patient feels shortness of breath. During the procedure, the doctor inserts a thin needle or plastic tube into the pleural space and draws out the excess fluid to detect the cause of the pleural effusion.
 
*The most common cause of heart failure is '''[[coronary artery disease]]''' ([[CAD]]), a narrowing of the small [[blood vessels]] that supply [[blood]] and oxygen to the [[heart]].
 
*Heart failure can also occur when an infection weakens the heart muscle. This condition is called [[cardiomyopathy]].
 
*Other heart problems that may cause heart failure are:
 
:*[[Congenital heart disease]]
:*[[Heart attack (patient information)|Heart attack]]
:*[[Heart valve disease]]
:*Some types of abnormal heart rhythms ([[arrhythmias]])
 
*Other diseases that can cause or contribute to heart failure:
 
:*[[Emphysema]]
:*Overactive [[thyroid]]
:*[[Anemia (patient information)|Severe anemia]]
:*[[Hypothyroidism|Underactive thyroid]]
 
==Who is at highest risk?==
Certain factors increase your risk of getting [[heart disease]], then increase your risk of getting [[heart failure]]. You are at a higher risk if you are:
*A [[woman]] aged 55 or older
*A [[man]] aged 45 or older
*[[Obesity]] or [[overweight]]
*[[Smoking]]
*High [[cholesterol]]
*[[High blood pressure]]
*Heavy drinking
*[[Diabetes]]
*Lack of [[exercise]]
 
==Diseases with similar symptoms==
There are a variety of diseases that cause shortness of breath, most of them lung diseases like [[asthma]] or [[chronic obstructive pulmonary disease]].
 
==Diagnosis==
*[[BNP]](Brain natriuretic peptide)/ [[NT-proBNP]] ([[N-terminal pro b-type natriuretic peptide]]) test: Either [[BNP]] or [[NT-proBNP]] may be used to help diagnose heart failure and to grade the severity of that heart failure. Furthermore, the levels can help doctors differentiate between heart failure and [[lung]] diseases.
 
*Cardiac biomarkers: This is a [[blood]] test. It needs to be done to identify your basic cardiac diseases such as [[Acute coronary syndromes|acute coronary syndrome]].
 
*[[Electrocardiogram]]: This is a simple and painless test that records the heart's electrical activity. It is needed to detect your primary cardiac diseases.
 
*[[Chest X-ray]]: The test can show an [[X-rays|x-ray]] silhouette of the [[heart]] and [[lungs]]. When heart failure appears, the picture may show an enlarged heart and [[pulmonary venous]] congestion.
 
*[[Echocardiogram]]: This is a painless and minimally invasive test for patients. [[Cardiac]] [[Echocardiography|echo]] can demonstrate both structure and function of the heart. It can tell the doctor the [[left ventricular]] [[ejection fraction]] and help doctor detect the heart function.
 
*[[Cardiac MRI]] (magnetic resonance imaging): [[Cardiac MRI]] can create both still and moving pictures of the [[heart]] and major [[blood vessels]]. It can help doctors analyze the structure and function of the heart and decide the treatment protocols for the patient.
 
*[[Thoracentesis]]: In heart failure, the [[Pleural cavity|pleural space]] is filled with more fluid than normal and can cause patient feels [[shortness of breath]]. During the procedure, the doctor inserts a thin needle or plastic tube into the [[pleural space]] and draws out the excess fluid to detect the cause of the [[pleural effusion]].


==When to seek urgent medical care?==
==When to seek urgent medical care?==
Patients with early heart failure can compensate. With the disease developing, the heart function decompensate and patients demonstrate a series of signs and symptoms. Call your health care provider if symptoms of heart failure develops. If you experience either of the following symptoms, seeking urgent medical care as soon as possible:

==Treatment options==
==Treatment==
Patients with heart failure have many treatment options. The selection depends on the condition of the disease. The options are general therapy, medications, [[percutaneous coronary intervention]] (PCI) and [[heart transplantation]].
===General Measures:===
Because heart failure is a clinical syndrome that is the end result of multiple heart diseases, the following measures are important:
*Treat basic cardiac disease such [[hypertension]], improve [[myocardial perfusion]] and perform surgery for stenotic or leaking [[heart valves]].
*Treat exacerbating conditions such as [[pneumonia]], [[arrhythmia]], [[hypokalemia]].
*Restrict [[sodium]] intake.


'''General therapy''':  
===Medications:===
Because heart failure is a clinical syndrome of multiple heart diseases, the following measurements are important.
*[[Diuretics]]: Diuretics can reduce volume overload and reduce [[shortness of breath]] and [[edema]]. There are three kinds of diuretics, [[loop diuretics]], [[thiazides]] and [[potassium-sparing diuretics]]. Given the risk of hypo or [[hyperkalemia]], the blood level of electrolyes should be checked regularly.  
:*Treating basic cardiac disease such as controlling blood pressure, improving myocardial perfusion and surgery for impaired heart valves。
:*Removing incentives such as treating [[pneumonia]], [[arrhythmia]], [[hypokalemia]].
:*Having a good rest, a low-sodium diet and managing stress.


'''Medications''':
*[[Angiotensin converting enzyme inhibitor]]s (ACEI): [[Angiotensin converting enzyme inhibitor]]s (ACEI) are widely used in cardiovascular diseases. This includes a large group of drugs, such as [[Enalapril]] (Vasotec/Renitec), [[Ramipril]] (Altace/Tritace/Ramace/Ramiwin), [[Quinapril]] (Accupril), [[Perindopril]] (Coversyl/Aceon), [[Lisinopril]] (Lisodur/Lopril/Novatec/Prinivil/Zestril) and [[Benazepril]] (Lotensin). They can improve symptoms and prognosis of heart failure in several ways including [[afterload]] reduction and favorable ventricular remodeling. Usual side effects include [[dry cough]] and [[angioedema]]. Patients who can not tolerate [[cough]] are often switched to an [[angiotensin II receptor antagonist]]. Patients with bilateral [[renal artery stenosis]] or severe [[renal impairment]] are not appropriate for [[angiotensin converting enzyme inhibitor]] (ACEI).
:*[[Diuretics]]: Diuretics can release the symptom of [[shortness of breath]] and the sign of [[edema]] quickly. There are three kinds of diuretics, [[loop diuretics]], [[thiazides]] and [[potassium-sparing diuretics]]. The patients should take the medicines under the doctor's direction and check the blood level of electrolyes regularly.
:*[[Angiotensin converting enzyme inhibitor]] (ACEI): [[Angiotensin converting enzyme inhibitor]] (ACEI) is widely used in cardivascular diseases. This includes a large group of drugs, such as [[Enalapril]] (Vasotec/Renitec), [[Ramipril]] (Altace/Tritace/Ramace/Ramiwin), [[Quinapril]] (Accupril), [[Perindopril]] (Coversyl/Aceon), [[Lisinopril]] (Lisodur/Lopril/Novatec/Prinivil/Zestril) and [[Benazepril]] (Lotensin). They can improve symptoms and prognosis of heart failure by several ways. Uasual side effects include [[dry cough]] and [[angioedema]]. Patients who can not tolerate [[cough]] are often switched to [[angiotensin II receptor antagonist]]. Patients with [[renal artery stenosis]] on both sides or severe [[renal impairment]] are not appropriate for [[angiotensin converting enzyme inhibitor]] (ACEI).
:*[[Angiotensin II receptor antagonist]]: These type of drugs can block the activation of angiotensin II AT1 receptors. Blockade of AT1 receptors directly causes [[vasodilation]], reduces secretion of [[vasopressin]], reduces production and secretion of [[aldosterone]]. Because angiotensin II receptor antagonists do not inhibit the breakdown of [[bradykinin]] or other [[kinin]]s, and are thus only rarely associated with the persistent [[dry cough]] and/or [[angioedema]] that limit ACE inhibitor therapy. Usual used drugs in heart failure are [[Candesartan]], [[Valsartan]], [[Telmisartan]], [[Losartan]], [[Irbesartan]], and [[Olmesartan]].
:*[[Beta blockers]]: Beta blockers can reduce heart rate which will lower the myocardial energy expenditure and then prolong the diastolic filling and lengthen coronary perfusion. It can also improve the ejection fraction of the heart and decrease the toxicity of catecholamine on myocardium. Clinical trials show [[Bisoprolol]], [[Carvedilol]] and sustained-release [[Metoprolol]] are specifically indicated as adjuncts to standard ACE inhibitor and diuretic therapy in congestive heart failure. Patients with [[asthma]], severe [[conduction block]] or severe [[heart failure]] are not appropriate for beta blockers. You should take these type of medicines under the doctor's direction.
:*[[Digitalis]]: Digitalis can strengthen the contractility of the heart. But because the pharmacokinetics of digoxin are complex, and the toxic levels are only slightly higher than therapeutic levels, digoxin dosing must be directed by the cardiologists.  


'''[[Percutaneous coronary intervention]]''' (PCI):  
*[[Angiotensin II receptor antagonist]]: These type of drugs can block the activation of angiotensin II AT1 receptors. Blockade of AT1 receptors directly causes [[vasodilation]], reduces secretion of [[vasopressin]], reduces production and secretion of [[aldosterone]]. Because angiotensin II receptor antagonists do not inhibit the breakdown of [[bradykinin]] or other [[kinin]]s, and are thus only rarely associated with the persistent [[dry cough]] and/or [[angioedema]] that limit ACE inhibitor therapy. Usual used drugs in heart failure are [[Candesartan]], [[Valsartan]], [[Telmisartan]], [[Losartan]], [[Irbesartan]], and [[Olmesartan]].


:*[[Coronary artery disease]] (CAD) is the main cause of heart fsailure. Removing the blockages in coronary artery can improve overall heart function, which may improve or resolve heart failure symptoms. The procedure is usually performed in the cardiac catherization lab. A catheter, a very small tube with a tiny deflated balloon on the end, is inserted through an incision in the groin area and pushed through to the diseased artery. Then the balloon is inflated to push open the artery. The balloon is removed once the artery has been fully opened. A stent may be placed during the procedure to keep the blood vessel open. Clinical trials have demonstrated that [[percutaneous coronary intervention]] (PCI) is a very effective and safe procedure to reopen blocked vessels and can improve the patient's condition.
*[[Beta blockers]]: Beta blockers can reduce heart rate which will lower the myocardial energy expenditure and then prolong the diastolic filling and lengthen coronary perfusion. It can also improve the ejection fraction of the heart and decrease the toxicity of catecholamines on the [[myocardium]]. Clinical trials show [[Bisoprolol]], [[Carvedilol]] and sustained-release [[Metoprolol]] are specifically indicated as adjuncts to standard [[ACE inhibitor]] and [[diuretic]] therapy in congestive heart failure. Patients with [[asthma]], severe [[conduction block]] or severe [[heart failure]] may not be appropriate candidates for [[beta blocker]] therapy.
*[[Digitalis]]: Digitalis can strengthen the contractility of the heart. But because the pharmacokinetics of digoxin are complex, and the toxic levels are only slightly higher than therapeutic levels, digoxin should be used judiciously under the close supervision of a cardiologist.


'''[[Left ventricular assist device]]''' (LVAD)
===Percutaneous coronary intervention (PCI):===
:*The left ventricular assist device (LVAD) is a mechanical pump-type device that can help maintain the pumping ability of a heart unable to effectively work on its own. One typical type of LVAD will have a tube going into the left ventricle that pulls blood from the ventricle into a pump. The pump then sends blood into the aorta. LVADs are typically used for weeks to months.


'''[[Heart transplantation]]'''
[[Coronary artery disease]] (CAD) and impaired blood flow to the heart is one of the main causes of heart failure. Removing the blockages in the coronary arteries can improve overall heart function, which may improve or resolve heart failure symptoms. The procedure is usually performed in the cardiac catherization lab. A catheter, a very small tube with a tiny deflated balloon on the end, is inserted through an incision in the groin area and pushed through to the diseased artery. Then the balloon is inflated to push open the artery. The balloon is removed once the artery has been fully opened. A stent may be placed during the procedure to keep the blood vessel open. Clinical trials have demonstrated that [[percutaneous coronary intervention]] (PCI) is a very effective and safe procedure to reopen blocked vessels and can improve a patient's symptoms.


==Diseases with similar symptoms==
===Left ventricular assist device (LVAD):===
:*[[Ischemic heart disease]]
 
:*[[Idiopathic dilated cardiomyopathy]]
The [[left ventricular assist device]] ([[LVAD]]) is a mechanical pump-type device that can help maintain the pumping ability of a heart unable to effectively work on its own. One typical type of [[Ventricular assist device|LVAD]] will have a tube going into the [[left ventricle]] that pulls blood from the [[ventricle]] into a pump. The pump then ejects blood into the [[aorta]]. LVADs are typically used for weeks to months as a "bridge" to more definitive therapy rather than a final or "destination" therapy.
:*[[Hypertension]]
 
:*[[Valvular heart disease]]
===Heart transplantation===
:*[[Familial dilated cardiomyopathy]]
[[Heart transplantation|Heart transplant]] may be the only effective treatment option for patients with severe, progressive heart failure that can not be helped by medications, dietary and lifestyle changes. During a [[heart transplant]] procedure, the surgeons connect the patient to a [[heart-lung machine]], which takes over the functions of the heart and lungs. Then the surgeons remove the diseased heart and replace it with the donor heart. Finally, the major blood vessels are reconnected and the new heart is ready to work. The outlook for people with heart transplants is good during the first few years after the transplant. Over 85 percent of patients live for more than a year after their operations.

==What to expect (Outlook/Prognosis)?==
The [[prognosis]] of people with heart failure can vary dramatically. The following factors may help the doctor estimate the [[prognosis]].
 
*The severity of the [[symptoms]]: It is well established that patients who have more severe [[symptoms]] of heart failure do not survive as long as those who have mild [[symptoms]]. For example, patients with class IV heart failure have the poorest [[prognosis]], while patients with class I have the best.
 
*Heart function: The [[ejection fraction]] of [[left ventricle]] ([[Ejection fraction|LVEF]]) is an important indicator of the [[prognosis]]. The more severely damaged your heart muscle is, the worse your [[ejection fraction]] and worse [[prognosis]] will be, regardless of your [[symptoms]].

Heart failure can be caused by treatable conditions such as [[hyperthyroidism]] or [[hypothyroidism]], [[anemia]], or [[vitamin deficiency]]. The [[prognosis]] of these conditions are generally excellent. Heart failure as a result of a valve condition may also be reversible if the valve problem is recognized early and fixed before permanent damage happens. People with heart failure caused by severe [[hypertension]] may see considerable improvement of their [[symptoms]] when they control their [[hypertension]]. But the majority of patients have heart failure as a result of [[coronary artery disease]] (CAD) have a worse [[prognosis]] and a higher death rate than people who have heart failure that is not a result of [[Coronary heart disease|CAD]].
 
*How long you've had heart failure: There is no specific length of time after which your heart function is unlikely to improve. General speaking, the longer you have had heart failure, the poorer [[prognosis]] may be even with appropriate treatment.


==What to expect (Outook/Prognosis)?==
*Compensatory factors: "compensatory factors" are various adjustments to correct the effects of heart failure on other organs. When heart failure occurs, various hormone levels including [[renin]], [[aldosterone]], [[norepinephrine]], [[atrial natriuretic peptide]], and [[prostaglandin]], may increase. Increases in these [[hormonal]] factors and other compensatory factors often make heart failure worse over time.

Overview

Heart failure is a clinical syndrome in which the heart cannot pump enough blood throughout the body. It can be caused by many types of cardiovascular diseases, such as coronary artery disease, hypertension, diabetes, valve heart diseases and endocrine diseases. Usual signs and symptoms include blood and fluid to back up into the lungs, edema in the feet, ankles and legs, tiredness and shortness of breath. Patient's symptoms, echocardiogram and cardiac MRI can be evidence to assess the heart function. Treatments include treating the underlying cause of your heart failure, medicines, percutaneous coronary intervention, left ventricular assist device (LVAD) and heart transplantation. The prognosis of heart failure varies widely. It depends on the cause of heart failure, left ventricular ejection fraction and the duration of the disease.

What are the symptoms of Congestive heart failure?

  • Early cases of heart failure do not have any symptoms.
  • Other health problems may also cause these symptoms. Only a doctor can tell for sure. A person with any of these symptoms should tell the doctor so that the problems can be diagnosed and treated as early as possible.

What causes Congestive heart failure?

  • Heart failure is a long-term (chronic) condition, but it can sometimes develop suddenly.
  • The condition may affect only the right side or only the left side of the heart. These are called right-sided heart failure or left-sided heart failure. More often, both sides of the heart are involved.
  • Both of these problems mean the heart is no longer able to pump enough oxygen-rich blood out to the rest of your body, especially when you exercise or are active.
  • Heart failure can also occur when an infection weakens the heart muscle. This condition is called cardiomyopathy.
  • Other heart problems that may cause heart failure are:
  • Other diseases that can cause or contribute to heart failure:

Who is at highest risk?

Certain factors increase your risk of getting heart disease, then increase your risk of getting heart failure. You are at a higher risk if you are:

Diseases with similar symptoms

There are a variety of diseases that cause shortness of breath, most of them lung diseases like asthma or chronic obstructive pulmonary disease.

Diagnosis

  • Electrocardiogram: This is a simple and painless test that records the heart's electrical activity. It is needed to detect your primary cardiac diseases.
  • Cardiac MRI (magnetic resonance imaging): Cardiac MRI can create both still and moving pictures of the heart and major blood vessels. It can help doctors analyze the structure and function of the heart and decide the treatment protocols for the patient.

When to seek urgent medical care?

Patients with early heart failure can compensate. With the disease developing, the heart function decompensate and patients demonstrate a series of signs and symptoms. Call your health care provider if symptoms of heart failure develops. If you experience either of the following symptoms, seeking urgent medical care as soon as possible:

Treatment

General Measures:

Because heart failure is a clinical syndrome that is the end result of multiple heart diseases, the following measures are important:

Medications:

  • Beta blockers: Beta blockers can reduce heart rate which will lower the myocardial energy expenditure and then prolong the diastolic filling and lengthen coronary perfusion. It can also improve the ejection fraction of the heart and decrease the toxicity of catecholamines on the myocardium. Clinical trials show Bisoprolol, Carvedilol and sustained-release Metoprolol are specifically indicated as adjuncts to standard ACE inhibitor and diuretic therapy in congestive heart failure. Patients with asthma, severe conduction block or severe heart failure may not be appropriate candidates for beta blocker therapy.
  • Digitalis: Digitalis can strengthen the contractility of the heart. But because the pharmacokinetics of digoxin are complex, and the toxic levels are only slightly higher than therapeutic levels, digoxin should be used judiciously under the close supervision of a cardiologist.

Percutaneous coronary intervention (PCI):

Coronary artery disease (CAD) and impaired blood flow to the heart is one of the main causes of heart failure. Removing the blockages in the coronary arteries can improve overall heart function, which may improve or resolve heart failure symptoms. The procedure is usually performed in the cardiac catherization lab. A catheter, a very small tube with a tiny deflated balloon on the end, is inserted through an incision in the groin area and pushed through to the diseased artery. Then the balloon is inflated to push open the artery. The balloon is removed once the artery has been fully opened. A stent may be placed during the procedure to keep the blood vessel open. Clinical trials have demonstrated that percutaneous coronary intervention (PCI) is a very effective and safe procedure to reopen blocked vessels and can improve a patient's symptoms.

Left ventricular assist device (LVAD):

The left ventricular assist device (LVAD) is a mechanical pump-type device that can help maintain the pumping ability of a heart unable to effectively work on its own. One typical type of LVAD will have a tube going into the left ventricle that pulls blood from the ventricle into a pump. The pump then ejects blood into the aorta. LVADs are typically used for weeks to months as a "bridge" to more definitive therapy rather than a final or "destination" therapy.

Heart transplantation

Heart transplant may be the only effective treatment option for patients with severe, progressive heart failure that can not be helped by medications, dietary and lifestyle changes. During a heart transplant procedure, the surgeons connect the patient to a heart-lung machine, which takes over the functions of the heart and lungs. Then the surgeons remove the diseased heart and replace it with the donor heart. Finally, the major blood vessels are reconnected and the new heart is ready to work. The outlook for people with heart transplants is good during the first few years after the transplant. Over 85 percent of patients live for more than a year after their operations.

Medications to avoid

Patients diagnosed with congestive heart failure should avoid using the following medications:


Patients diagnosed with NYHA Class III or IV heart failure should avoid using the following medications:

  • Pioglitazone
  • Rosiglitazone
  • Finogolimod
    If you have been diagnosed with NYHA Class III or IV heart failure, consult your physician before starting or stopping any of these medications.


Patients diagnosed with Overt cardiac failure should avoid using the following medications:

  • Atenolol
  • Labetalol
    If you have been diagnosed with Overt cardiac failure, consult your physician before starting or stopping any of these medications.


Patients diagnosed with Decompensated cardiac failure should avoid using the following medications:

  • Esmolol
  • Fingolimod
    If you have been diagnosed with Decompensated cardiac failure, consult your physician before starting or stopping any of these medications.

Patients diagnosed with Progressive cardiac failure should avoid using the following medications:

  • Mannitol
    If you have been diagnosed with Progressive cardiac failure, consult your physician before starting or stopping any of these medications.

Prevention of Congestive heart failure

Heart failure is a terminal syndrome of heart diseases. And heart disease is the leading cause of the death and a major cause of disability in the U.S. Cardiologists have verified there are many things you can do reduce your chances of getting heart disease. Keeping track of symptoms and reporting any changes that concern you to your healthcare professonal and working more closely with your healthcare team.

  • Monitoring your blood pressure
  • Exercise regularly
  • Quitting smoking
  • Checked for diabetes and if you have it, keep it under control
  • Know your cholesterol and triglyceride levels and keep them under control
  • Eat a lot of fruits and vegetables
  • Maintain a healthy weight
  • Managing stress

What to expect (Outlook/Prognosis)?

The prognosis of people with heart failure can vary dramatically. The following factors may help the doctor estimate the prognosis.

  • The severity of the symptoms: It is well established that patients who have more severe symptoms of heart failure do not survive as long as those who have mild symptoms. For example, patients with class IV heart failure have the poorest prognosis, while patients with class I have the best.
  • The causes of heart failure: Heart failure associated with alcohol use or pregnancy may spontaneously recover itself over time. Heart failure can be caused by treatable conditions such as hyperthyroidism or hypothyroidism, anemia, or vitamin deficiency. The prognosis of these conditions are generally excellent. Heart failure as a result of a valve condition may also be reversible if the valve problem is recognized early and fixed before permanent damage happens. People with heart failure caused by severe hypertension may see considerable improvement of their symptoms when they control their hypertension. But the majority of patients have heart failure as a result of coronary artery disease (CAD) have a worse prognosis and a higher death rate than people who have heart failure that is not a result of CAD.
  • How long you've had heart failure: There is no specific length of time after which your heart function is unlikely to improve. General speaking, the longer you have had heart failure, the poorer prognosis may be even with appropriate treatment.
  • Compensatory factors: "compensatory factors" are various adjustments to correct the effects of heart failure on other organs. When heart failure occurs, various hormone levels including renin, aldosterone, norepinephrine, atrial natriuretic peptide, and prostaglandin, may increase. Increases in these hormonal factors and other compensatory factors often make heart failure worse over time.
