Inotrope use was an independent predictor of post-discharge 1-month mortality with a HRadjusted of 1.839 (95% CI 1.227–2.757, p = 0.003), while old age, hyponatremia, renal replacement therapy during admission, high uric acid, and high c-reactive protein were the associated independent predictors (Table 5). The gene discussed is CRP; the disease is Hyponatremia.
