NPPB and hyperlipidemia: The univariate Cox regression analysis identified several risk factors for poor prognosis: Scr ≥ 101.5 μmol/L (HR = 2.209, 95% CI 1.372–3.557, P = 0.001), BUN ≥ 8.61 mmol/L (HR = 3.709, 95% CI 2.270–6.061, P < 0.001), UA ≥ 462 μmol/L (HR = 2.625, 95% CI 1.631–4.228, P < 0.001), BNP levels (HR = 1.000, 95% CI 1.000–1.000, P < 0.001), male gender (HR = 1.764, 95% CI 1.067–2.915, P = 0.027), hyperlipidemia (HR = 0.567, 95% CI 0.351–0.916, P = 0.027), and re-hospitalization (HR = 0.480, 95% CI 0.280–0.826, P = 0.008).
