Comparisons of serum GPBB, Mb and BNP levels in study population before chemotherapy and those after chemotherapy respectively
| Before chemotherapy | p | After chemotherapy | p | |
|---|---|---|---|---|
| GPBB (pg/mL) | ||||
| Normal heart group | 22.19 ± 7.16 | 0.343 | 30.09 ± 6.46* | < 0.001 |
| Cardiotoxicity group | 23.46 ± 3.49 | 39.89 ± 10.22* | ||
| Mb (pg/mL) | ||||
| Normal heart group | 31.71 ± 12.58 | 44.75 ± 16.49* | ||
| Cardiotoxicity group | 31.55 ± 13.22 | 0.952 | 51.59 ± 16.43* | 0.030 |
| BNP (pg/mL) | ||||
| Normal heart group | 29.80 ± 14.53 | 0.276 | 65.28 ± 21.96* | < 0.001 |
| Cardiotoxicity group | 33.15 ± 15.93 | 86.01 ± 36.84* |
Note: GPBB, glycogen phosphorylase isoenzyme BB; Mb, myoglobin; BNP, brain natriuretic peptide. * refers to p < 0.05 vs the serum GPBB, Mb and BNP levels in study population before chemotherapy.
