After adjustment for potential confounding factors (including age, Killip classification, diabetes, MI, stroke, serum albumin, WBC, hemoglobin, serum creatinine and LVEF), multivariate analysis showed that thrombocytopenia remained a significant predictor of infection risk in such patients (OR, 2.09; 95%CI 1.32–3.27; p = 0.001) (Table 3). The gene discussed is ALB; the disease is infection.
