Persistent right ventricular-pulmonary arterial coupling dysfunction and its association with iron metabolism in patients with heart failure
In patients with heart failure (HF), a reduced tricuspid annular plane systolic excursion to pulmonary artery systolic pressure (TAPSE/PASP) ratio—a surrogate marker for right ventricular-pulmonary arterial (RV-PA) coupling—is a known predictor of poor prognosis (1, 2). This ratio provides integrated information...
