ALB and Hypertension: For RAS patients who required stenting for moderate to severe stenosis, CORAL subgroup analysis showed that the severity of hypertension and the difference in peak systolic flow velocity at both ends of the stenotic lesion were risk factors that affected the prognosis of stenting, and patients with a low urinary albumin/creatinine level (<22.5 mg/g) had a tendency of better prognosis (17).
