Jan 29, 2025 · Ejection fraction is a measurement of the percentage of blood leaving the heart each time it squeezes. When the heart squeezes, it's called a contraction.

Nov 12, 2024 · Echocardiogram. An echocardiogram uses sound waves to show how blood flows through the heart and heart valves. Sensors attached to the chest and sometimes the legs check the heart rhythm during the te

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 …

Sep 24, 2021 · Atrial fibrillation may further reduce stroke volume in its own right. Current practice is to average at least five consecutive cardiac cycles during atrial fibrillation when assessing transvalvular gradients, effectively concealing high-signal gradients that meet criteria for severe aortic stenosis that if taken alone would qualify as severe aortic stenosis.
