Randomised controlled trial
Anthracyclines and Biomarkers of Myocardial Injury
- Randomised controlled trial
- single-blind
- sham-controlled
- prematurely halted
Authors' conclusion
TnT and cMyC significantly increased during anthracycline chemotherapy with 81% having a TnT ≥14 ng/L at cycle 6. RIC did not affect the rise in biomarkers, but there was a small increase in early cancer deaths, possibly related to the greater proportion of patients with metastatic disease randomized to the RIC group (54%vs 37%).
