Anthracyline (ANT) has been demonstrated as a useful treatment for leukemia and solid tumors. However, ANT has previously reported cardiotoxic effects, which can reduce the therapeutic index for cancer treatment. This study aimed to investigate the associations of glycogen phosphorylase isoenzyme BB (GPBB), myoglobin (Mb), and brain natriuretic peptide (BNP) with anthracycline (ANT-induced cardiotoxicity (AIC)) amongst the Chinese population. Patients suffering from leukemia were recruited. Electrocardiogram and echocardiography were used along with chemotherapy to determine left ventricular ejection fraction (LVEF), mitral ratio of peak early to late diastolic filling velocity (E/A), E-wave deceleration time (EDT), and isovolumic relaxation time (IVRT). Double-antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA) was employed to examine and compare serum GPBB, Mb, and BNP levels. Following chemotherapy, the patients presented higher levels of serum GPBB, Mb, and BNP than before chemotherapy treatment. The levels of LVEF (%), E/A, and IVRT were significantly decreased after chemotherapy, while EDT was markedly increased. The cumulative ANT dose was positively corelated to serum GPBB, Mb, and BNP levels while it was negatively corelated to LVEF levels. In conclusion, serum GPBB, Mb, and BNP levels in combination might provide higher diagnostic accuracy in the early detection of AIC compared with other single indicators.

The photoelectrochemical immunoassay of glycogen phosphorylase BB (GPBB) was studied. A methyl orange/TiO nanorod heterojunction was constructed on a fluorine-doped tin oxide electrode by hydrothermal synthesis, calcination, and chemical adsorption. A sandwich immune structure consisting of GPBB as the first antibody, GPBB, and a CdS@mesoporous silica-ascorbic acid (AA)-GPBB as secondary antibody composite was constructed on each of the selected well surfaces of a 96-well microplate.

Recently, surface enhanced Raman scattering (SERS) has attracted much attention in medical diagnosis applications owing to better detection sensitivity and lower limit of detection (LOD) than colorimetric detection. In this paper, a novel calibration-free SERS-based μPAD with multi-reaction zones for simultaneous quantitative detection of multiple cardiac biomarkers - GPBB, CK-MB and cTnT for early diagnosis and prognosis of acute myocardial infarction (AMI) are presented. Three distinct Raman probes were synthesised, subsequently conjugated with respective detecting antibodies and used as SERS nanotags for cardiac biomarker detection.

The early detection of acute myocardial infarction (AMI) upon the onset of chest pain symptoms is crucial for patient survival. However, this detection is challenging, particularly without a persistent elevation of ST-segment reflected in an electrocardiogram or in blood tests. A majority of the available point-of-care testing devices allow accurate and rapid diagnosis of AMI.

Cardiac markers are used to evaluate functions of heart. However, there are no satisfactory cardiac biomarkers for the diagnosis of acute myocardial infarction (AMI) within 4 h of onset of chest pain. Among novel cardiac markers, glycogen phosphorylase BB (GPBB) is of particular interest as it is increased in the early hours after AMI.
