In addition to the abovementioned biomarkers, other parameters including cardiac troponin I (cTnI) (22), high-sensitivity cardiac troponin(hs-cTnT) (23), ejection fraction (EF) (24), left ventricle longitudinal function (25), left ventricle septum thickness (15), systolic blood pressure (26), uric acid (27), albumin-to creatinine ratio (28), albumin (21), and proteinuria (21) have also been explored as indicators in patients with AL amyloidosis in recent years. This evidence concerns the gene ALB and AL amyloidosis.
