What happens when LVEF is low?

Low ejection fraction causes Cardiomyopathy, which causes your heart muscle to become enlarged, thick or stiff. Coronary artery disease, where plaque builds up in the two main arteries that supply blood to your heart and blocks blood flow. Heart attack, when blood flow to your heart muscle became blocked and damaged it.

How much LVEF is normal?

A normal left ventricular ejection fraction (LVEF) ranges from 55\% to 70\%. An LVEF of 65\%, for example means that 65\% of total amount of blood in the left ventricle is pumped out with each heartbeat. Your EF can go up and down, based on your heart condition and how well your treatment works. HF-pEF.

What is mild LV dysfunction?

LV dysfunction occurs when the left ventricle is either defective or damaged, thus disrupting healthy . Normal LV function can be disturbed due to several causes. Certain cardiac defects like valvular malformations or diseases block the passage of blood into the body.

How bad is an ejection fraction of 35?

If you have an EF of less than 35\%, you have a greater risk of life-threatening irregular heartbeats that can cause sudden cardiac arrest/death. If your EF is below 35\%, your doctor may talk to you about treatment with an implantable cardioverter defibrillator (ICD) or cardiac resynchronization therapy (CRT).

What does LVEF 30 mean?

Normal = LVEF 50\% to 70\% (midpoint 60\%) Mild dysfunction = LVEF 40\% to 49\% (midpoint 45\%) Moderate dysfunction = LVEF 30\% to 39\% (midpoint 35\%) Severe dysfunction = LVEF less than 30\%

Can LVEF improve?

Since the earliest studies of vasodilator therapy in patients with heart failure (HF) with reduced ejection fraction (HFrEF), it has been noted that left ventricular (LV) ejection fraction (LVEF) can improve during the course of therapy (1).

Is ejection fraction of 35 good?

A normal EF is 50-65 percent. If your EF is below 35 percent, your risk for SCA increases dramatically. The easiest way to determine your EF is a painless ultrasound called an echocardiogram that uses sound waves to produce images of your heart.

Is LVEF 30 good?
