Difference between Right Heart Failure vs Left Heart Failure: Heart failure can manifest in either the left side, right side, or both sides of the heart. The primary distinction between left-sided heart failure and right-sided heart failure lies in which side of the heart is affected. Left-sided heart failure occurs when the left side of the heart is weakened, leading to a decreased ability to pump blood effectively into the body. On the other hand, right-sided heart failure occurs when the right side of the heart is weakened, resulting in fluid accumulation in the veins, which causes swelling in the legs, ankles, and liver.
Differences Between Right Heart Failure vs Left Heart Failure
|
Feature |
Right Heart Failure |
Left Heart Failure |
|
Definition |
Right heart failure occurs when the right ventricle is unable to pump blood effectively, leading to a buildup of fluid that causes swelling, especially in the lower body. |
Left heart failure occurs when the left ventricle cannot pump blood adequately, leading to blood buildup in the veins of the lungs. |
|
Common Cause |
Isolated right heart failure is less common and can be caused by left-sided heart failure, chronic obstructive pulmonary disease (COPD), or other lung diseases. |
Left heart failure is more common than right heart failure and can be caused by a heart attack, chronic high blood pressure, arrhythmia, or coronary artery disease (CAD). |
|
Frequency |
Right heart failure is less common than left heart failure. |
Left heart failure is more common than right heart failure. |
|
Symptoms |
Common symptoms include fluid retention and swelling, heart palpitations, shortness of breath, discomfort in the chest, and weight gain. |
Symptoms typically include congestion in the lungs, affecting breathing, swelling, and fluid retention in the body. |
|
Neck Vein Pressure |
Blood pressure in the jugular vein may significantly increase, causing the veins to distend. |
A person may experience a mild to moderate elevation in their jugular vein blood pressure. |

What Is Right Heart Failure?
Right heart failure develops when the right ventricle cannot pump blood properly, leading to a buildup of fluid that causes swelling, especially in the lower body. It is less common than left heart failure and is often caused by left-sided heart failure, chronic obstructive pulmonary disease (COPD), or other lung diseases. Symptoms include fluid retention and swelling, heart palpitations, shortness of breath, discomfort in the chest, and weight gain. Blood pressure in the jugular vein may significantly increase, causing the veins to distend.
Key Features of Right Heart Failure
- Involves the inability of the right ventricle to pump blood effectively
- Fluid buildup in the lower body, leading to swelling
- Commonly caused by left-sided heart failure, COPD, or other lung diseases
- Symptoms include fluid retention, heart palpitations, shortness of breath, chest discomfort, and weight gain
- Significant increase in blood pressure in the jugular vein, causing vein distension.
What Is Left Heart Failure?
Left heart failure occurs when the left ventricle is unable to pump blood adequately, leading to blood buildup in the veins of the lungs. It is more common than right heart failure and is often caused by a heart attack, chronic high blood pressure, arrhythmia, or coronary artery disease (CAD). Symptoms include congestion in the lungs, affecting breathing, as well as swelling and fluid retention in the body. An individual may have a mild to moderate rise in blood pressure in the jugular vein.
Key Features of Left Heart Failure
- Involves the inability of the left ventricle to pump blood sufficiently.
- Blood buildup in the veins of the lungs, causing breathing difficulties
- Commonly caused by a heart attack, chronic high blood pressure, arrhythmia, or CAD
- Symptoms include lung congestion, breathing difficulties, swelling, and fluid retention
- Mild to moderate increase in blood pressure in the jugular vein.

Similarities Between Right Heart Failure and Left Heart Failure
- Both types of heart failure result from the heart's inability to effectively pump blood.
- They can cause symptoms such as fluid retention, swelling, shortness of breath, and chest discomfort.
- Risk factors for both include family history, age, high blood pressure, certain cancer treatments, diabetes, obesity, and lifestyle factors like smoking and excessive alcohol consumption
