GPT and myocardial ischemia: For predicting mortality, models based on the clinical characteristics (age > 80 years, presence of IHD), or GGT ≥ 26 IU, or ALT ≥ 17 IU, or combination of these variables demonstrated low-modest values for AUC (0.591–0.700), while in other tests/models AUC ranged from 0.803 to 0.722.
