A left ventricle (LV) ejection fraction of about 50% to 70% is categorized as normal. A mildly reduced LV ejection fraction is usually between 41% and 49%. A reduced LV ejection fraction is usually 40% or less. Even if you have a normal ejection fraction, your overall heart function may not be healthy. Talk with your health care provider if you ...
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.
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.
Low gallbladder ejection fraction. The amount of tracer leaving the gallbladder is low after medicine is given to make it empty. This might indicate chronic inflammation, known as chronic cholecystitis. Radioactive tracer detected in other areas. Radioactive tracer found outside of the biliary system might indicate a leak.
Uncontrolled high blood pressure is the most common cause of left ventricular hypertrophy. Complications include irregular heart rhythms, called arrhythmias, and heart failure.
Heart failure with reduced ejection fraction (HFrEF), also called systolic heart failure: This is a type of left-sided heart failure. 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
Diagnosis. To diagnose left ventricular hypertrophy, a healthcare professional does a physical exam and asks questions about your symptoms and family's health history.

Dilated cardiomyopathy is a type of heart muscle disease that causes the heart chambers (ventricles) to thin and stretch, growing larger.
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.
