- Abstract:
- BACKGROUND: Whether aspartate aminotransferase (AST) to alanine aminotransferase (ALT) ratio (De Ritis ratio) with AST and ALT activities within the reference range has prognostic value is unknown. METHODS: This study included 3392 patients with stable coronary artery disease and AST and ALT activities within the reference range. Patients are categorized in groups according to tertiles of the De Ritis ratio: a group with De Ritis ratio in the 1st tertile (De Ritis ratio: 0.22 to 0.81; n = 1131), a group with De Ritis ratio in the 2nd tertile (De Ritis ratio: >0.81 to 1.09; n = 1130) and a group with De Ritis ratio in the 3rd tertile (De Ritis ratio: >1.09 to 3.40; n = 1131). The primary endpoint was 3-year mortality. RESULTS: The mean value of De Ritis ratio was 1.00 ± 0.39 (range: 0.22-3.40). Overall, there were 234 deaths at 3 years: 43 deaths in patients of 1st tertile, 75 deaths in patients of 2nd tertile and 116 deaths in patients of 3rd tertile of De Ritis ratio (Kaplan-Meier estimates of 3-year mortality, 4.4 %, 7.8 % and 12.5 %, respectively; (adjusted hazard ratio = 1.24, 95 % confidence interval 1.12 to 1.38; P < 0.001 for 1 unit higher De Ritis ratio). The C-statistic of the risk prediction model for mortality with baseline demographical and clinical variables without De Ritis ratio was 0.803 [0.774-0.832] and it increased to 0.810 [0.782-0.839] after inclusion of De Ritis ratio into the model (P = 0.038). CONCLUSIONS: An elevated De Ritis ratio with aminotransferase levels within the reference range was associated with the increased risk of mortality.
