Abstract
The incidence of anthracycline-induced cardiotoxicity typically occurs within the first year after chemotherapy, but the changes in cardiac function and biomarkers beyond this initial year have not been adequately investigated. We analyzed 105 consecutive patients followed for 24 months after anthracycline-containing chemotherapy at Fukushima Medical University Hospital from June 2018 to April 2021. Echocardiography and blood tests for cardiac troponin I and B-type natriuretic peptide (BNP) were conducted at baseline, and 3, 6, 12, and 24 months after chemotherapy initiation. In the whole patient cohort, BNP levels increased from 10.5 [6.3-18.3] pg/mL at baseline to 19.2 [12.1-34.5] pg/mL at 24 months after chemotherapy (P < 0.01). Based on BNP levels at 24 months, the patients were divided into 2 groups: a BNP-elevated group (n = 57) and a BNP-normal group (n = 48). In the BNP-elevated group, time-course changes revealed that BNP levels remained stable until 12 months, but increased at 24 months. Multivariate logistic analysis identified age, total anthracycline dose, and baseline BNP levels as predicting factors for elevated BNP levels at 24 months. Subclinical BNP elevation was observed at 24 months of follow-up after initiation of anthracycline-containing chemotherapy.
