RESULTS: Our analysis revealed a statistically significant association between the compound endpoint of heart failure and ischemic heart disease and the protein biomarkers cysteine rich protein 61 (CYR61), glycoprotein nonmetastatic melanoma protein B (GPNMB) and activated leukocyte cell adhesion molecule (ALCAM) in samples collected after treatment for cHL. Here, GPNMB is linked to heart failure.
