Expert Insights Into Amyloidosis: Ejection Fraction: It's Just a Fraction

Dr. Julie Rosenthal, Director of the Cardiac Amyloidosis Program at Mayo Clinic in Arizona, introduces us to the cardiovascular system and summarizes cardiac amyloidosis. She then discusses the echocardiogram and how it is used to look for abnormalities, such as thickening of the heart wall and pericardial effusion. Animated patient videos clearly convey how an impaired amyloid heart looks from multiple perspectives. She offers a tutorial on ejection fraction, what it is, how it is calculated, and why not all ejection fractions are the same despite the numbers. Importantly, she highlights that stroke volume is actually the more meaningful measurement of a patient’s cardiac output and why.
