AbstractPrevious studies had shown that an increased aspartate aminotransferase to alanine aminotransferase ratio (AST/ALT ratio) was associated with cardiovascular disease. This study aimed to assess the relationship between AST/ALT ratio and all-cause and cardiovascular mortality in patients with hypertension.By March 31, 2020, a cohort of 14,220 Chinese hypertensive patients was followed up. The end point was all-cause and cardiovascular death. Hazard ratios (HRs) and 95% CIs were calculated for mortality associated with AST/ALT ratio, using Cox proportional hazards models and competing risk model.In an average of 1.7 years of follow-up, 1.39% (n = 198) of patients died, 55.5% (n = 110) of whom from cardiovascular disease. AST/ALT ratio was associated with increased risk of all-cause death (HR:1.37, 95% CI:1.15-1.63) and cardiovascular death (HR:1.32, 95% CI:1.03-1.68) after adjustment for other potential confounders. Compared with low AST/ALT ratio (Tertile 1), high AST/ALT ratio was associated with high cause mortality (Tertile 2: HR:1.35, 95% CI:0.86-2.10; Tertile 3: HR:2.10, 95% CI:1.37-3.21; P for trend <.001). Compared with low AST/ALT ratio (Tertile 1), a statistically significant increased risk of cardiovascular mortality was also observed (Tertile 2: HR:1.27, 95% CI:0.70-2.29; Tertile 3: HR:1.92, 95% CI:1.09-3.37; P for trend <.001). High AST/ALT ratio was also associated with high cardiovascular mortality (Tertile 2: HR:1.27, 95% CI:0.70-2.29; Tertile 3: HR:1.92, 95% CI:1.09-3.37; P for trend <.001).Present study indicated that increased AST/ALT ratio levels were predictive of all-cause and cardiovascular mortality among Chinese hypertensive patients.Trial registration: CHICTR, CHiCTR1800017274.
