However, only 5 predictors were enrolled into nomogram after combined with the actual clinical situation, including HF (OR: 2.13, 95% CI: 2.76–5.95), ECG (OR: 6.11, 95% CI: 1.05–8.66), pneumonia (OR: 3.62, 95% CI: 1.43–9.85), BNP (OR: 4.66, 95% CI: 3.07–24.06), and LDH (OR: 1.90, 95% CI: 0.19–9.39).
