F2 and acute kidney injury: The independent risk factors for myocardial injury after traumatic hemorrhagic shock were a heart rate of >100 beats/min (OR, 3.33; 95% CI, 1.56–7.09; p = 0.002), hemoglobin levels of <70 g/L (OR, 3.50; 95% CI, 1.15–10.60; p = 0.027), prothrombin time of >15 s (OR, 2.39; 95% CI, 1.12–5.10; p = 0.024), AKI (OR, 2.75; 95% CI, 1.27–5.93; p = 0.01), and a higher APACHE II score (OR, 1.08; 95% CI, 1.01–1.15; p = 0.018) (Table 3).
