Indeed, the extent of lung congestion has been linked not only to markers of capillary hydrostatic pressure (PAWP and NT-proBNP) and plasma oncotic pressure (hypoalbuminemia) [41] but also to anaemia, elevated pulmonary vascular resistance, declining renal function, and the presence of coronary artery disease (CAD) [52]. Here, NPPB is linked to coronary artery disorder.
