Patients were divided into 3 groups according to their uACR level (normal group: uACR < 30mg/g, moderately increased group: 30mg/g≤ uACR < 300mg/g, severely increased group: 300mg/g≤ uACR). The main outcome of the study was cardiovascular mortality and all-cause mortality.Results: During a median follow-up of 2.1 years, among 2832 patients (mean age: 63.3 ± 9.9 years, 29.1% women), 434 patients (15.3%) had moderately increased uACR, and 203 patients (7.2%) had severely increased uACR. Compared to patients in normal group, patients had higher cardiovascular mortality in moderately increased group and severely increased group (2.5% vs 9.9% vs 16.7%, P < 0.001), as well as all-cause mortality. After adjusting confounders, the risk of cardiovascular mortality remained higher in moderately increased group (adjusted hazard ratio [aHR]: 3.13; 95% confidence interval [CI]: 2.04– 4.81) and severely increased group (aHR: 4.54; 95% CI: 2.58– 8.01) than in normal group, as well as all-cause mortality.Conclusion: In our study, we found nearly a quarter of DM patients with ASCVD had increased uACR, and they have over 2- or 3-fold risk of cardiovascular mortality than those with normal uACR. UACR is a helpful indicator for risk stratification and treatment target for DM patients with ASCVD.Keywords: diabetes mellitus, atherosclerotic cardiovascular disease, urinary albumin creatinine ratio, cardiovascular mortality
