Increased values of the pulmonary variables (BROSJOD score, pCO2 and LUS) showed moderate correlations with NT-proBNP and all the echocardiographic parameters indicative of pulmonary hypertension (TRJG, ATET, LVEI and RVLV) and global myocardial dysfunction (LVTX and RVTX) but not with the parameters of systolic myocardial dysfunction (LVEF or TAPSE) (Table 4). Here, NPPB is linked to pulmonary arterial hypertension.
