Those readmitted for heart failure (HF+) versus those not-readmitted (HF-) were slightly older, more frequently an inpatient at the time of their index TTE, had a higher NT-proBNP measurement, greater LV hypertrophy, more advanced diastolic dysfunction, a higher E/e’ ratio, larger right ventricular basal diameters, larger left atrial sizes, and greater degrees of mitral, and tricuspid regurgitation on their index TTE (all p < 0.05; S1 Table in S1 File). Here, NPPB is linked to heart failure.
