Heart Failure

Heart Failure Treatment Van Nuys | Sylmar | Sherman Oaks | TarzanaHeart failure occurs when the heart is not pumping blood as it should, making it unable to provide the body's cells with the oxygen and nutrients they require. Despite its name, it is not a complete shutdown of the heart, but rather a chronic and progressive condition, albeit one that is usually treatable with medication and lifestyle changes. Heart failure is responsible for the greatest number of hospitalizations in people 65 years and older.

Heart failure may be asymptomatic, or its symptoms may come on suddenly, in which case they may be more severe than chronic symptoms, and may quickly worsen.

Causes of Heart Failure

Heart failure is caused by damage to the heart muscle. That damage may be caused by the following:

  • Heart attack
  • Coronary-artery disease
  • Infection
  • Alcohol and/or drug abuse
  • High blood pressure
  • Thyroid disease
  • Kidney disease
  • Diabetes

Various congenital heart defects can also cause heart failure.

Symptoms of Heart Failure

Heart failure may be asymptomatic, or its symptoms may come on suddenly, in which case they may be more severe than chronic symptoms, and may quickly worsen. Common symptoms of heart failure include the following:

  • Fatigue
  • Weakness
  • Irregular heartbeat
  • Shortness of breath
  • Swelling of legs, ankles and feet
  • Weight gain
  • Coughing

Mental confusion is also a symptom of heart failure; it is caused by reduced blood flow to the brain, or a buildup of sodium in the blood.

Diagnosis of Heart Failure

To diagnose heart failure, a patient's medical history is taken, and a complete physical exam is performed. Additional tests, including the following, may be ordered:

  • Electrocardiogram (EKG)
  • Chest X-ray
  • Echocardiogram
  • Blood tests
  • Treadmill stress test
  • Electrophysiology (EP) study

Following a diagnosis of heart failure, it is ranked, depending on the severity of its symptoms, in one of four classes.

Treatment of Heart Failure

Chronic heart failure requires lifelong treatment to manage symptoms and prevent additional damage to the heart. Designed to improve a patient's quality of life, treatment for heart failure addresses the underlying cause of the condition to prevent it from worsening. Lifestyle changes, medication and surgery are all used to treat heart failure; in the majority of cases, more than one treatment is used.

Congestive Heart Failure

Heart Failure Treatment San Fernando ValleyCongestive heart failure (CHF) occurs when the heart muscle, whether from weakness or stiffening, does not pump with sufficient force to circulate the blood properly. As a result, blood backs up in other parts of the body, such as the liver, abdomen, lower legs and lungs, because the heart is unable to keep pace with the body's circulatory needs. While CHF can occur on either side of the body, it usually begins on the left, where the left ventricle, the primary pumping chamber of the heart, is located.

An unhealthy lifestyle can contribute to congestive heart failure, but congenital defects, coronary artery disease, diabetes or hypertension are also underlying causes.

Types of Congestive Heart Failure

There are four types of congestive heart failure: left-sided, right-sided, systolic and diastolic. Left-sided heart failure results in fluid backup in the lungs, whereas right-sided heart failure causes fluid backup in the abdomen, or legs and feet.

In systolic heart failure, there is a pumping problem: the left ventricle cannot contract strongly enough. Diastolic heart failure indicates that there is a filling problem because the left ventricle cannot fully relax.

CHF can be either chronic or acute.

Causes of Congestive Heart Failure

An unhealthy lifestyle can contribute to congestive heart failure, but congenital defects, coronary artery disease, diabetes or hypertension are also underlying causes.

Coronary Artery Disease

The most common cause of CHF is coronary artery disease, in which there is a buildup of fatty deposits in the arteries that supply blood to the heart muscle. This accumulation of plaque is known as atherosclerosis.

Heart Attack

If, as a result of plaque buildup, the arteries rupture, a blood clot forms, blocking blood flow to an area of the heart. This may result in permanent damage that weakens the heart muscle.


When a patient has hypertension (high blood pressure), the heart is working harder than necessary to circulate the blood, causing the heart muscle to thicken. Over time, the heart muscle weakens to the point that it no longer pumps blood efficiently.

Faulty Heart Valves

Blood flow is directed by the heart valves. If a valve is damaged, the blood backs up, causing the heart to work harder than it usually does. Heart-valve damage may be the result of a congenital defect, a heart infection, or coronary artery disease.


Cardiomyopathy (damage to the heart muscle) can result from infection (such as myocarditis), alcohol or drug abuse, chemotherapy, or a disease process. In some cases, cardiomyopathy is caused by genetic factors.

Congenital Heart Defects

Infants may be born with a defective heart in which, because of anatomical abnormalities, the valves or chambers do not work properly, resulting in CHF.

Other causes of CHF include heart arrhythmia, infections and diseases, allergic reactions, certain medications, and blood clots in the lungs.

Symptoms of Congestive Heart Failure

There are a number of symptoms of congestive heart failure, including the following:

  • Ascites (abdominal swelling)
  • Edema (swelling) in the legs, ankles and feet
  • Fatigue and weakness
  • Reduced ability to exercise
  • Increased need to urinate during the night
  • Persistent coughing or wheezing
  • Production of pink-tinged phlegm
  • Rapid or irregular heartbeat
  • Shortness of breath, especially upon exertion

When CHF is caused by a heart attack, patients also experience chest pain.

Diagnosis of Congestive Heart Failure

In order to diagnose CHF, in addition to a comprehensive medical examination, the following tests may be administered:

  • Blood tests
  • Chest X-rays
  • Electrocardiogram (EKG or ECG)
  • Echocardiogram
  • Stress test
  • CT or MRI scan
  • Coronary angiogram

In some cases, a myocardial biopsy is performed.

Treatment of Congestive Heart Failure

CHF must be treated; if not, it can lead to kidney failure and death. Medication and surgery are both treatment options.


Medications used to treat CHF include the following:

  • Beta blockers
  • Diuretics
  • Digoxin (digitalis)
  • Aldosterone antagonists
  • Inotropes

Angiotension-converting enzyme inhibitors (ACD) or angiotension II receptor blockers are also used to treat CHF.

Surgical Treatments

Surgical treatments are undertaken when medications do not resolve the problem. Several types of surgeries, including the following, can be performed to treat CHF:

  • Coronary bypass
  • Heart-valve repair or replacement
  • Implantation of cardioverter-defibrillators (ICDs)
  • Cardiac resynchronization therapy (CRT)
  • Implantation of ventricular assistive device (VAD)

In the most severe cases of CHF, implanting a total artificial heart (TAH) or having a heart transplant may be necessary.
