NPPB and hydrops fetalis: In the same cohort of HFpEF patients [94], we demonstrated that both peak B-linecounts (HR 1.50, 95% CI, 1.21–1.85, p <0.001) and their changes (HR1.34, 95% CI 1.12–1.62, p = 0.002) were retained as independentpredictors of outcome (composite of cardiovascular death or HF hospitalisation at1 year), along with BNP and E/e’ ratio.
