NPPB and hydrops fetalis: Following multivariable analyses, B-line change >10 (assessedwith the 8-zone protocol) was retained as an independent predictor ofcardiovascular death or HF hospitalisation at long-term, along with peak VO2<16 mL/kg/min, minute ventilation/carbon dioxide production slope >36, PASP>50 mmHg, and resting NT-proBNP >900 pg/mL.
