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. Here, TNNI3 is linked to AL amyloidosis.
