Nonalcoholic Fatty Liver Disease Is Associated with Increased Atrial Fibrillation Risk in an Elderly Chinese Population: A Cross-Sectional Study

Figure 2

Prevalence of AF in an elderly Chinese population stratified by NAFLD status on ultrasound combined with normal or elevated serum AST/ALT/GGT concentration. Without NAFLD: without diagnosed NAFLD. Simple steatosis: NAFLD with normal range of AST/ALT/GGT. NASH: NAFLD with elevated range of AST/ALT/GGT. Normal range for AST or AST level: ≤40 U/L; elevated range for AST or ALT level: >40 U/L; normal range for GGT level in male: ≤50 U/L; elevated range for GGT in male: >50 U/L; normal range for GGT level in female: ≤32 U/L; elevated range for GGT in female: >32 U/L. P value =0.001/=0.003/=0.027 by the χ2 test in AST/ALT/GGT group.
