NPPB and cardiomyopathy: Also, abnormal NT-pro-BNP (cardiomyopathy, age > 1 yr abnormal if NT-pro-BNP ≥ 100 pg/mL; age < 1 yr abnormal if NT-pro-BNP ≥ 150 pg/mL) during the first 90 days of anthracycline therapy is significantly related to LV remodeling (thickness to dimension ratio) by echocardiogram four years later [58].
