Understanding Heart Failure: Symptoms, Causes, and Treatment Options

Heart failure is a condition where your heart can't pump enough blood to meet your body's needs. It doesn't mean that your heart has stopped working, but rather that it isn't working as efficiently as it should. Heart failure affects nearly 7 million Americans, and about 1 in 4 people will be diagnosed with it in their lifetime.

Symptoms of Heart Failure

The symptoms of heart failure can vary from person to person and may be mild or severe. Some common symptoms include:

  • Tiredness or fatigue

  • Shortness of breath

  • Cough or wheezing

  • Swelling in the ankles, legs, or belly

  • Difficulty doing daily activities

Other symptoms may include a raised need to urinate at night, appetite loss, dizziness, weakness, and chest pain.

Causes of Heart Failure

Heart failure can be caused by many different conditions that damage the heart muscle, including:

  • Coronary artery disease (CAD)

  • Heart attack

  • Cardiomyopathy

  • High blood pressure

  • Heart valve disease

  • Thyroid disease

  • Kidney disease

  • Diabetes

Sometimes, more than one condition can combine to cause heart failure.

Diagnosing Heart Failure

If you have symptoms of heart failure, your doctor will ask about your medical history and do a physical exam. They may also order tests such as:

  • Blood tests

  • B-type natriuretic peptide (BNP) blood test

  • Chest X-ray

  • Echocardiogram

  • EKG or ECG

  • Cardiac catheterization

  • Stress test

These tests can help your doctor determine the cause and severity of your heart failure.

Treating Heart Failure

Treatment for heart failure depends on the cause and severity of your condition. Your doctor may recommend lifestyle changes such as:

  • Losing weight

  • Exercising regularly

  • Eating a healthy, low-sodium diet

  • Quitting smoking

  • Managing stress

  • Getting enough sleep

Your doctor may also prescribe medications to help manage your heart failure, such as:

  • ACE inhibitors and angiotensin receptor blockers

  • Beta blockers

  • Angiotensin receptor-neprilysin inhibitors

  • Digoxin

  • Diuretics and aldosterone antagonists

In some cases, surgery or other procedures may be needed to treat heart failure. These may include:

  • Coronary bypass surgery

  • Heart valve repair or replacement

  • Implantable cardioverter defibrillator

  • Cardiac resynchronization therapy

  • Ventricular assist device

  • Heart transplant

Living with Heart Failure

If you have heart failure, there are many things you can do to manage your condition and improve your quality of life. These include:

  • Taking your medications as prescribed

  • Monitoring your symptoms and reporting any changes to your doctor

  • Keeping a balance of fluids and limiting salt intake

  • Exercising regularly as recommended by your doctor

  • Attending regular doctor appointments and cardiac rehabilitation if recommended

It's also important to avoid medications that can worsen heart failure, such as NSAIDs and some cough and cold medicines. Always check with your doctor before starting any new medication.

With the right treatment and lifestyle changes, many people with heart failure are able to manage their condition and enjoy a good quality of life. If you have any questions or concerns about heart failure, don't hesitate to talk to your doctor.
