What is Congestive heart failure?

Heart failure, also known as Congestive heart failure, is a highly complex condition in which the heart cannot pump blood as expertly as it should. Contrary to its name, heart failure does not mean the heart is failing or about to stop working. Instead, it means the heart muscle has become less able to contract over time, or mechanical problems limit its ability to fill with blood. As a result, it cannot meet the body's demands, and blood returns to the heart faster than it can be pumped out - and the lungs and body becomes congested. In addition, this condition means that enough oxygen-rich blood fails to reach other organs in the body.

Heart failure can disturb both sides of your heart:

- With Right-side heart failure- the heart is too delicate to pump enough blood to your lungs for oxygen.
- In Left-heart failure- your heart cannot pump enough oxygen-rich blood to your body. This arises when the left side of your heart turns:
- Too weak to pump enough blood.
- is too thick or tight to relax and fill with enough blood.

Symptoms of Congestive heart failure

Heart failure symptoms are calculated on which side of your heart and condition are affected. Symptoms are usually caused by low blood flow and fluid in the body. The symptoms of systolic heart failure are confusion or forgetfulness, chest pain, dizziness, fast or irregular heartbeat, frequent coughing, lack of appetite, and frequent urination. The diastolic CHF symptoms include fatigue, difficulty in concentration, wheezing, coughing, difficulty breathing at night, and fluid retention, causing swelling and nausea.

Fluid buildup occurs because blood flows too slowly through the heart. As a result, blood backs up into the blood vessels, allowing blood to return to the heart. As a result, fluid can leak out of blood vessels and build up in body tissues, causing swelling (oedema) and other problems.

Symptoms of congestive heart failure are:

- Shortened of breath
- Heart palpitations
- Fatigue
- Weight gain
- A dry, hacking cough,
- A full or hard stomach,
- Swelling in your ankles, legs, and abdomen,
- Loss of appetite or upset stomach

Causes of congestive heart failure

Congestive heart failure is caused by many conditions, such as:

- Arrhythmia
- Cardiomyopathy
- Endocarditis
- Heart valve disease
- Diabetes
- Obesity
- High blood pressure
- Lung diseases such as COPD (chronic obstructive pulmonary disease)

Over time left-sided failure can lead to right-sided failure.

Diagnosis of Congestive Heart Failure

Below are some tests commonly used to assess and treat congestive heart failure (CHF).

- Echocardiogram: This test is painless and uses sound waves (ultrasound) to take moving pictures of the heart.
- Right and Left Cardiac Catheterization: This invasive testing procedure is performed in a cardiac catheterisation laboratory.
- Sleep Study: A sleep study or polysomnography (PSG) is a multi-component test that electronically transmits and notes specific physical activity while you sleep.
- Cardiopulmonary Exercise Test: CPET tells how your lungs, heart, and muscles work together when you exercise.

Stages of Congestive Heart Failure

Four heart failure stages are observed in congestive heart failure, Stages A, B, C, and D. They range from having a high risk to developing advanced heart failure.

Stage A-  Stage A of congestive heart failure (CHF) is the earliest stage of the condition, in which a person is at risk of developing heart failure but does not yet have any structural heart abnormalities or symptoms. This stage also means that you are at high risk of developing heart failure due to your family history of congestive heart failure or because you have these conditions:

- Family history of cardiomyopathy
- Coronary artery disease
- Diabetes

Treatment-  Treatment of Stage A includes:

- Regular exercise
- Angiotensin-converting enzyme inhibitors (ACE-I) and angiotensin II receptor blockers (ARBs) are medications commonly used to treat high blood pressure and congestive heart failure if you have coronary artery disease, diabetes, high blood pressure, or other cardiac conditions.

Stage B- In this stage, the person has structural heart abnormalities, such as a previous heart attack or abnormal heart valves, but has not yet developed symptoms of heart failure.

Treatment:

- Changes in lifestyle, such as maintaining a healthy weight,
- Regular exercise and quitting smoking.
- Medications such as ACE inhibitors, beta-blockers, and aldosterone antagonists may also help manage blood pressure and improve heart function.
- Surgery or procedure possible to treat blocked coronary arteries, heart attack, valve disease (valve repair or replacement), or congenital heart disease.

Stage C: In this stage, the person has structural heart abnormalities and is experiencing symptoms of heart failure, such as shortness of breath, fatigue, and swelling in the legs and ankles.

Treatment: Treatment in this stage aims to minimise symptoms

- Medications such as diuretics and ACE inhibitors
- Benazepril,
- Captopril,
- Enalapril,
- Fosinopril,
- Moxipril, etc.

Beta-blockers may be used to reduce fluid buildup and improve heart function.  This may be achieved with the following:

- Atenolol,
- Bisoprolol,
- Nodolol,
- Nebivolol, etc.
- A diuretic if symptoms continue
- Possible fluid restriction
- Possible implant cardiac defibrillator (ICD) therapy

If these treatments show improvement, it is advised to continue treatment to stop the progression of the next stage

Stage D: This is the most severe stage of CHF, in which the person has advanced structural heart disease and is experiencing severe symptoms of heart failure despite treatment. This is the most severe stage of CHF, in which the person has advanced structural heart disease and severe symptoms of heart failure despite treatment. Symptoms include extreme fatigue, weakness, shortness of breath, irregular heartbeat, swelling in the belly area, wheezing, persistent cough, etc.

Treatment-

- Hospice care or palliative care,
-  a heart transplant or implantation of a ventricular assist device (VAD), which can help to support heart function.
- Heart surgery
- Continuous infusion of inotropic drugs

Surgeries are a revolution in treating heart failure. Below are some of the few types of surgeries that can help treat this condition:

Types of Surgeries

If the heart is not responding to medication, surgery is required. This procedure will help to work more efficiently and to minimise further complications.

- Coronary artery bypass Graft: CABG involves creating a new route for blood to flow around the blocked or narrowed portion of the artery, using a healthy blood vessel from another body part.
- Valve Repair or Replacement- In this procedure, the surgeon may repair or replace the valve with a new one. Valve repair involves reshaping or rebuilding the valve to function more effectively. Valve replacement removes and replaces the damaged valve with an artificial valve made of metal, plastic, or biological tissue.
- Ventricular assist device (VAD)- Ventricular assist devices are typically used as a bridge to a heart transplant or as a long-term treatment option for people not eligible for a heart transplant. The device works by taking over the pumping function of the heart's ventricles, the chambers that pump blood to the body. The VAD is implanted in the chest, attached to the heart, and the blood vessels carry blood to and from the heart. There are different categories of VADs, including
- left ventricular assist devices (LVADs) and
- right ventricular assist devices (RVADs)
- Heart Transplant- Heart transplantation is a surgical procedure that may be considered a treatment option for people with end-stage congestive heart failure (CHF) who are not responding to other treatments. During a heart transplant, the heart from a donor is replaced.

Heart failure can be a chronic disease that requires long-term treatment. However, with treatment, the signs and symptoms of heart failure may improve.
