Difference Between CHF Left and CHF Right


CHF or congestive heart failure is a chronic condition where the heart is unable to pump enough blood to meet the body's demands. It is a serious and potentially life-threatening condition that requires prompt medical attention. The heart is responsible for pumping blood throughout the body, delivering oxygen and nutrients to the tissues and organs. When the heart is unable to do this effectively, it can lead to a wide range of symptoms and complications. One important distinction in CHF is between left-sided and right-sided heart failure, which have different causes, symptoms, and treatments.

What is Congestive Heart Failure (CHF) Left?

Left-sided CHF occurs when the left ventricle, which is responsible for pumping oxygen-rich blood to the body, is unable to do so effectively. This can result in a buildup of fluid in the lungs, which can cause shortness of breath, coughing, and wheezing. Other common symptoms of left-sided CHF include fatigue, weakness, dizziness, and rapid or irregular heartbeat. Left-sided CHF is the most common form of CHF, accounting for approximately two-thirds of all cases.

There are several causes of left-sided CHF, including coronary artery disease, high blood pressure, and valve problems. Coronary artery disease occurs when the arteries that supply blood to the heart become narrowed or blocked, reducing blood flow and oxygen delivery to the heart muscle. High blood pressure, or hypertension, can also lead to left-sided CHF by putting additional strain on the heart and causing it to work harder to pump blood. Valve problems, such as aortic stenosis or mitral regurgitation, can also contribute to left-sided CHF by impairing the heart's ability to pump blood effectively.

Treatment for left-sided CHF focuses on reducing symptoms and managing the underlying causes. This may involve lifestyle changes, such as losing weight, quitting smoking, or reducing salt intake, as well as medications to improve heart function, lower blood pressure, or control symptoms. In severe cases, surgery or heart transplant may be necessary.

There are two types of left-sided heart failure −

  • Systolic Failure − Also termed as heart failure with minimized ejection fraction (HFrEF). This failure happens when the ability of the heart’s left ventricle to contract reduces. The heart is unable to pump with enough force for maintaining adequate circulation for a given demand.

  • Diastolic Failure − Also termed as diastolic dysfunction. This is a heart failure with preserved ejection fraction, or HFpEF. It happens when the left ventricle is so stiff that the heart is unable to fill with adequate blood supply during the relaxing period between each beat.

What is Congestive Heart Failure (CHF) Right?

Right-sided CHF occurs when the right ventricle, which is responsible for pumping blood to the lungs to pick up oxygen, is unable to do so effectively. This can result in a buildup of fluid in the legs, ankles, and abdomen, as well as enlargement of the liver and a decrease in appetite. Other common symptoms of right-sided CHF include fatigue, weakness, and shortness of breath, especially with exertion.

There are several causes of right-sided CHF, including left-sided CHF, lung disease, and pulmonary hypertension. When left-sided CHF is not treated, it can lead to increased pressure in the blood vessels of the lungs, which can then cause right-sided CHF. Lung disease, such as chronic obstructive pulmonary disease (COPD), can also lead to right-sided CHF by impairing the lungs' ability to exchange oxygen and carbon dioxide effectively. Pulmonary hypertension, which is high blood pressure in the blood vessels of the lungs, can also contribute to right-sided CHF by putting additional strain on the heart.

Treatment for right-sided CHF is similar to that for left-sided CHF, focusing on reducing symptoms and managing the underlying causes. This may involve lifestyle changes, such as quitting smoking or losing weight, as well as medications to improve heart function or control symptoms. In severe cases, oxygen therapy or surgery may be necessary.

Differences: CHF Left and CHF Right

The following table highlights the major differences between CHF Left and CHF Right −

Characteristics

CHF Left

CHF Right

Definition

CHF left is described as a chronic condition that occurs when the left ventricle does not adequately pump blood out to your body. As this chronic condition progresses, fluid builds up in your lungs, that makes breathing difficult.

The right chamber or the right ventricle, carries “used” blood from the heart back to your lungs for resupplying oxygen.

So, when there is failure of heart from right side, the right ventricle has lost its tendency to pump, which means your heart is not supplied with enough blood and the blood backs up into the veins. If such a situation arises, your ankles, your legs, and belly often swell.

Symptoms

  • Dyspnea

  • Cardiac asthma

  • Hemoptysis

  • Nocturia

  • Fatigue

  • Decreased mental and physical performance

  • Exercise intolerance

  • Pulmonary Edema

  • Cheyne-stokes respiration

  • Awakening at night with shortness of breath

  • Nausea

  • Vomiting

  • Upper abdominal pain

  • Distended neck veins

  • Peripheral edema

  • Edema of hand dorsum

  • Coughing

  • Wheezing

  • Sudden weight gain

  • Increased urge to urinate

Signs

  • Fourth heart sound (presystolic gallop)

  • Third heart sound (protodiastolic gallop)

  • Pulmonary congestion (wheezing and abnormal sputum cytology)

  • Cold extremities

  • Fourth heart sound

  • Proteinuria

  • Venous congestion (increased pressure in central venous, congestion in hepatomegaly, positive hepatojugular reflux)

  • Cardiac cirrhosis

Complications

Kidney damage can occur as one of the complications. Without treatment, another complication is enlarged heart. If the heart becomes enlarged and dilated, it is more prone to harmful, abnormal heart rhythms.

Congestive hepatopathy could occur to what is known as cardiac cirrhosis, which in turn, can ultimately lead to liver failure.

Causes

  • Hypertension

  • Aortic stenosis

  • Left ventricular infarction

  • Pericardial diseases

  • Restrictive cardiomyopathy

  • Pressure overload – outflow obstruction

  • Mitral or aortic valvular insufficiency

  • Ischemic heart disease (Atherosclerosis)

  • COPD

  • Right ventricular infarction

  • Tricuspid regurgitation

  • Myocardial heart disease effecting right heart

Congestion

Congestion in lungs

Congestion in jugular veins, lower extremities and veins

Conclusion

In conclusion, congestive heart failure is a serious and potentially life-threatening condition that requires prompt medical attention.

Left-sided CHF occurs when the left ventricle is unable to pump oxygen-rich blood to the body effectively, while right-sided CHF occurs when the right ventricle is unable to pump blood to the lungs effectively.
