Ejection fraction (EF): Physiology, Measurement & Clinical Evaluation

…fraction <55%. This implies that left ventricular pumping capacity is reduced and it is synonymous with heart failure with reduced ejection fraction (HFREF ). Average ejection…

Heart Failure With Preserved Ejection Fraction: Diagnosis and Treatment

…or both. Consequently, relatively small increases in venous return can produce disproportionate increases in left ventricular and left atrial pressure. At rest, filling pressures may…
