Ejection fraction: An important heart test - Mayo Clinic
Feb 17, 2023 · Ejection fraction can be measured with imaging tests, including: Echocardiogram. This is the most common test used to measure ejection fraction. An echocardiogram uses sound waves to create pictures of the beating heart. It shows how blood flows through the heart and heart valves. Cardiac catheterization.
Heart failure with preserved ejection fraction (HFpEF): More than ...
May 20, 2015 · Nearly half of all patients with heart failure have a normal ejection fraction (EF). The prevalence of this syndrome, termed heart failure with preserved ejection fraction (HFpEF), continues to increase in the developed world, likely because of the increasing prevalence of common risk factors, including older age, female sex, hypertension, metabolic syndrome, renal dysfunction and obesity.

The left ventricle can't squeeze as strong as it should. The heart isn't strong enough to pump enough blood to the body. Heart failure with preserved ejection fraction (HFpEF), also called diastolic heart failure
Heart failure - Diagnosis and treatment - Mayo Clinic
Apr 20, 2023 · Ejection fraction. Ejection fraction is a measurement of the percentage of blood leaving your heart each time it squeezes. This measurement is taken during an echocardiogram. The result helps classify heart failure and guides treatment. An ejection fraction of 50% or higher is considered ideal.
Sudden cardiac arrest - Diagnosis and treatment - Mayo Clinic
Dec 7, 2024 · Ejection fraction. This test is done during an echocardiogram. It's a measurement of the percentage of blood leaving the heart each time it squeezes. A typical ejection fraction is 50% to 70%. An ejection fraction of less than 40% increases the risk of sudden cardiac arrest. Chest X-ray. This test shows the size and shape of the heart and lungs.
Cardiac asthma: What causes it? - Mayo Clinic
Jan 6, 2024 · Cardiac asthma is not a form of asthma. It's a type of coughing or wheezing that occurs with left heart failure.
