"The haemodynamic milieu of the heart failure syndrome is present, despite a normal to hyperdynamic ejection fraction, with elevated left sided filling pressures (E/e' > 15), right sided pressure overload (measured right ventricular systolic pressure (RVSP) >42 mmHg) and cardiac indices typically above 3.5 litres per minute per square kilogram. Other common features include increased left ventricular end diastolic diameters, with subnormal end systolic diameters. An elevated heart rate is also commonly present."
"F. P. Weber syndrome"
"The single finding with the best ROC curve is the right ventricular systolic pressure; as measured by Doppler, a right ventricular systolic pressure >42 mmHg has demonstrated a 92% sensitivity and 100% specificity (in a study group with abnormally elevated cardiac indices) 5."

"There are several conditions that can predispose to this situation:"
"severe reduction of the blood's capacity to carry oxygen and nutrients; i.e. severe anaemia"
