Systolic and Diastolic Heart Failure

Know The Difference Between Systolic and Diastolic Heart Failure

Heart failure occurs when the heart muscle is damaged by various conditions, including high blood pressure, obesity, coronary artery disease, and congenital disabilities. This damage makes it difficult for your heart to pump blood effectively through your body. Systolic and diastolic heart failure are two different types of heart failure. Heart failure can be caused by many things, including high blood pressure and diabetes.

Systolic heart failure mainly affects the left side of your heart, while diastolic heart failure affects both sides equally. Learn the difference between systolic and diastolic heart failure here!

Left-Sided VS Right-Sided Heart Failure

Right-sided heart failure is when the right side of the heart cannot pump blood effectively. The right side of the heart is responsible for pumping blood to the lungs.

If there is a problem with this, then blood will not be able to get to the lungs as it should. This means less oxygen will be delivered to the rest of your body, and you may feel breathless and tired. There are many reasons why someone might develop right-sided heart failure, such as:

A virus or bacteria that causes inflammation in the lungs (pneumonia). Smoking and other types of lung disease (chronic obstructive pulmonary disease) A blood clot forming in one of their arteries (coronary artery disease)

Left-sided heart failure is a chronic condition in which the left side of your heart cannot pump enough blood to meet your body’s needs. The term “left-sided” refers to the side of the heart that receives oxygen-rich blood from the lungs and sends it to the rest of your body (the right side).

Left-sided heart failure typically causes fatigue, swelling in your legs and ankles, and shortness of breath. It can also cause fluid buildup in your lungs (pulmonary edema) or abdomen (ascites). Left-sided heart failure may be caused by congenital abnormalities (congenital disabilities), high blood pressure, or other conditions such as cardiomyopathy or coronary artery disease.

Systolic Heart Failure

Systolic heart failure occurs when the heart can’t pump out enough blood to meet an individual’s needs. It’s a common complication of coronary artery disease, the most common type of heart disease.

Symptoms of systolic heart failure include shortness of breath, fatigue, and swelling in the legs or abdomen due to fluid buildup.

A doctor will diagnose systolic heart failure based on symptoms and may order tests like an echocardiogram or a chest X-ray for further evaluation. The doctor may also order blood tests if they suspect that you have another condition that causes fluid retention (such as kidney disease).

Treatments depend on your condition; however, in some cases, medications may be prescribed to help manage symptoms while waiting for surgery options such as valve replacement surgery or cardiac transplantation if available at your hospital facility.

Diastolic Heart Failure

Diastolic heart failure occurs when the left ventricle is unable to relax. As a result, it can’t fill with blood and pump blood through the body.

Diastolic heart failure is a complication of other conditions that cause the heart to become enlarged and stiff. For example, it occurs in people who have had a heart attack, had high blood pressure, or had diabetes for many years. It also occurs in people who have been diagnosed with cardiomyopathy, which is a disease of the heart muscle.

Diastolic heart failure sometimes causes shortness of breath during physical activity or lying down. Sometimes, people with this condition don’t experience any symptoms until they develop fluid buildup in their lungs or swelling in their legs and feet from fluid buildup (edema).

Differences Between Systolic and Diastolic Heart Failure

The two are different types of heart failure and happen for various reasons. Systolic dysfunction occurs when the left chamber of your heart doesn’t pump blood out as efficiently as it should. An arrhythmia often causes this—a problem with how your heart beats—or a blockage in one or more blood vessels that supply blood to your body.

Diastolic dysfunction occurs when the right chamber of your heart cannot relax properly and fill up with blood after each contraction, causing pressure to build up in the arteries.


Heart failure can be caused by any disease that damages or weakens the heart muscle and interferes with its ability to pump effectively. The most common cause of heart failure is coronary artery disease (atherosclerosis). Other causes include high blood pressure, cardiomyopathy, valve problems, and chest injury involving the heart muscle.

We hope this article helped you understand the difference between systolic and diastolic heart failure. Heart failure is a severe condition that can lead to death if not treated properly, so it’s important to know what type of heart failure you have and take steps toward recovery.
