NPPB and hydrops fetalis: A more recent retrospective analysis among elderly individualswith heart failure has shown that specific parameters such as wall thickness,atrial dimensions, NT-proBNP, and pulmonary vein velocities better predicted HFreadmission in HFpEF than HFrEF; further echocardiographic structural anddiastolic variables augmented prediction of HF readmission compared withcomorbidities alone, regardless of LVEF, though predictive accuracy remainedmodest [19].
