ALB and acute coronary syndrome: Studies have suggested that albumin levels are negatively correlated with the incidence of AMI (He et al., 2016; Djousse et al., 2002), and in patients with acute coronary syndrome (ACS), low albumin levels were found to be independent predictors of all-cause mortality and the deterioration of heart failure during hospitalization (Xia et al., 2018; Kurtul et al., 2016; Gonzalez-Pacheco et al., 2017).
