The use of inotropes was an independent predictor of in-hospital clinical events (ORadjusted 5.459, 95% CI 3.622–8.227, p < 0.001), whereas other independent predictors included factors such as old age, low body mass index, baseline chronic renal failure, HFrEF, high uric acid level, high C-reactive protein, and renal replacement therapy during admission (Table 3). The gene discussed is CRP; the disease is chronic kidney disease.
