Hello, I'm an expert in cardiovascular health with a focus on heart function and its various measurements. One of the key indicators we look at is the ejection fraction (EF), which is a measure of how well the heart is pumping blood with each beat.

Ejection fraction is typically expressed as a percentage and is calculated by comparing the volume of blood pumped out of the heart (stroke volume) to the volume of blood in the heart before it contracts (end-diastolic volume). A normal ejection fraction is usually between 50% and 70%. This means that with each heartbeat, the heart is effectively ejecting about half to two-thirds of the blood in the left ventricle.

Now, to answer your question: Can ejection fraction be too high?

In general, an ejection fraction that is higher than the normal range is not typically considered a problem. However, it's important to note that an EF that is consistently above 70% could be a sign of a hypertrophied heart, which means the heart muscle is thicker than normal. This can be a result of high blood pressure, genetic conditions, or other heart diseases. Hypertrophy can lead to a stiffening of the heart muscle, which may eventually affect the heart's ability to pump effectively.

It's also worth mentioning that an ejection fraction that is too high could be due to a measurement error or a misinterpretation of the data. Therefore, it's crucial to have a comprehensive evaluation by a healthcare professional to understand the context and implications of an elevated ejection fraction.

Cardiomyopathy is a condition in which the heart is abnormally enlarged, thickened or stiffened. An EF of 55 to 75 percent is considered normal. A higher than normal ejection fraction could indicate the presence of certain heart conditions, such as hypertrophic cardiomyopathy.read more >>
