ALB and heart failure: Patients in the mild- and high-risk stratification had a higher age and bedridden, lower BMI, a longer length of stay, higher NYHA class and heart rate, higher patients with chronic kidney disease, lower use rate of ACEI/ARB and β-blocker, lower hemoglobin, lymphocyte, total protein, albumin, triglyceride, total cholesterol, and low-density lipoprotein concentrations, a higher creatinine and BNP concentration, higher incidence of readmission for heart failure and all-cause death in one year on discharge (all P < 0.05).
