Automated calculation of gallbladder ejection fraction

European Journal of Nuclear Medicine, 1983
We have developed a computer method which by automatically locating the border of the gallbladder in each image and subtracting a varying location-dependent background corresponding to the gallbladder border overcomes the difficulties associated with quantitating gallbladder contraction.

Is heart failure with midrange ejection fraction similar to preserved ejection fraction? Against

Revista Clínica Española (English Edition), 2017
The new European guidelines (2016) for heart failure (HF) include the concept of HF with intermediate left ventricular ejection fraction (LVEF), i.e. an LVEF between 40 and 49%. Although few studies have been carried out, there are claims that HF with intermediate LVEF is not the same as HF with preserved LVEF.

Heart failure with reduced ejection fraction

Nature Reviews Disease Primers, 2017
Heart failure is a global public health problem that affects more than 26 million people worldwide. The global burden of heart failure is growing and is expected to increase substantially with the ageing of the population. Heart failure with reduced ejection fraction accounts for approximately 50% of all cases of heart failure in the United States and ...

ESPVR, Ejection Fraction and Heart Failure

Cardiovascular Engineering, 2010
The problem of heart failure with preserved ejection fraction (HFpEF) has recently received much attention. In this study we discuss some relations that connect ejection fraction EF to the parameters describing the end-systolic pressure-volume relation (ESPVR).
