Logistic regression identified admission BNP as an independent risk factor for MACE (OR: 4.029, 95% CI: 1.753-9.262, P = .001), myocardial infarction (OR: 4.405, P = .038), heart failure (OR: 8.420, P = .002), delayed cerebral ischemia (OR: 3.449, P = .013), and hydrocephalus (OR: 13.726, P = .020). Here, NPPB is linked to Hydrocephalus.
