What is Heart Failure | Revere Health

Heart failure, also referred to as congestive heart failure, is a condition that occurs when the heart doesn’t pump blood properly. Conditions like narrowed arteries or high blood pressure can gradually weaken or stiffen the heart, eventually making it unable to pump  blood efficiently.

Treatments can improve signs and symptoms of heart failure and help increase lifespan, though not all conditions that lead to heart failure can be reversed.

Symptoms and Complications

Heart failure can be either chronic (building over time) or acute (sudden). Signs and symptoms of heart failure include:

  • • Shortness of breath during exertion or when lying down
  • • Fatigue and weakness
  • • Swelling in the legs, ankles and feet
  • • Rapid or irregular heartbeat
  • • Decreased ability to exercise
  • • Persistent cough or wheezing with white or pink blood-tinged phlegm
  • • Increased need to urinate at night
  • • Swelling in the abdomen
  • • Sudden weight gain due to fluid retention
  • • Lack of appetite and nausea
  • • Difficulty concentrating or decreased alertness
  • • Sudden, severe shortness of breath and coughing up pink, foamy mucus
  • • If caused by a heart attack, chest pain may be present

See your doctor if you are experiencing any of these symptoms. If you feel chest pain, fainting or severe weakness, rapid heartbeat, shortness of breath, chest pain, or coughing up mucus, seek immediate medical attention. These signs are not always indicative of heart failure, but could be due to other life-threatening conditions.

Complications from heart failure can include:

  • • Kidney damage or kidney failure
  • • Heart valve issues
  • • Heart rhythm issues
  • • Liver damage

Causes and Risk Factors

Heart failure is often caused by other conditions that have weakened the heart, but this is not always the case. It may also become stiff and stop filling properly between beats.

Heart failure can involve the left side of the heart (left ventricle), the right side of the heart (right ventricle), or both. It generally begins on your left side, the heart’s main pumping chamber. Some of the conditions that can cause heart failure include:

  • • Coronary artery disease and heart attack. CAD is the most common form of heart disease and the most common cause of heart failure. It involves reduced blood flow to the heart due to buildups over time. A heart attack may also form a blood clot, blocking blood flow to the heart and weakening the muscle in some cases.
  • High blood pressure (hypertension): If blood pressure is too high, the heart has to work harder to circulate it, which can weaken the heart muscle.
  • • Faulty heart valves
  • • Cardiomyopathy: Damage to the heart muscle.
  • • Myocarditis: Inflammation of the heart muscle
  • • Congenital heart defects: Defects present at birth
  • Heart arrhythmias: Abnormal heart rhythms
  • • Other disease: Including diabetes, HIV, hyperthyroidism, hypothyroidism, hemochromatosis (buildup of iron) or amyloidosis (buildup of protein) can contribute to heart failure.

There are numerous risk factors for heart failure, including:

  • • High blood pressure
  • • Coronary artery disease
  • • Heart attack
  • • Diabetes and some diabetes medications
  • • Other medications
  • Sleep apnea
  • • Congenital heart defects
  • • Valvular heart disease
  • • Viruses
  • • Alcohol use
  • • Tobacco use
  • • Obesity
  • • Irregular heartbeats

Diagnosis and Treatment

Diagnosing and properly classifying heart failure depends on your symptoms and risk factors. It begins with a physical exam, and may require a variety of potential tests.

Treatment for heart failure falls into two categories: Medications and surgeries/devices. Medication may include the following, sometimes more than one at a time:

  • • ACE inhibitors: These widen blood vessels and lower blood pressure
  • • Angiotensin II receptor blockers: Similar to ACE inhibitors, or an alternative for those who need one
  • • Beta blockers: These slow heart rate, reduce blood pressure and can help reduce heart damage
  • • Diuretics: Diuretics make you urinate more often and keep fluid from collecting in the body
  • • Aldosterone antagonists: Diuretics with additional properties
  • • Inotropes: Intravenous medications for people with severe heart failure
  • • Digoxin (Lanoxin): Also called digitalis, this is a drug that increases heart muscle contraction strength

Surgical and device options include the following:

  • • Coronary bypass surgery: Using blood vessels from elsewhere in the body to bypass a clogged artery
  • • Heart valve repair or replacement: Repairing or replacing the heart valve
  • • Implantable cardioverter-defibrillators (ICDs): A device similar to a pacemaker that monitors heart rhythm
  • • CRT therapy: Another item similar to a pacemaker
  • • Heart pumps: Mechanical devices implanted into the body to help the heart pump blood
  • • Heart transplant: For people who are not helped by medication or surgery, a healthy donor heart replacement may be needed.

Prevention

Preventing heart failure involves eliminating your risk factors, which mainly comes from making lifestyle changes. Such changes may include:

  • • Not smoking
  • • Controlling conditions like high blood pressure and diabetes
  • • Staying active
  • • Eating a healthy diet and maintaining healthy weight
  • • Reducing and managing stress

If you fear you have some of the signs of heart failure, contact your doctor or emergency medical services right away.
