Background
Cardiac dysfunction associated with anthracyclines is a significant side effect of chemotherapy, and early detection is crucial. We aimed to assess the diagnostic value of combining global longitudinal strain (GLS) with biomarkers for the early detection of anthracycline-related cardiac dysfunction.
Methods
In a prospective cohort study, 80 consecutive adult patients (mean age 51 ± 11 years; 68.8% females) were screened and underwent 2D echocardiographic assessments and biomarker assessments [high-sensitivity troponin-I (hs-Troponin-I) and NT-pro brain natriuretic peptide (NT-proBNP)] before and after anthracycline-based chemotherapy’s initial regimen. The patients were followed up for 12 weeks to monitor for the development of cardiotoxicity.
Results
Ten patients (12.5%) developed cardiotoxicity at the end of the 12-week follow-up. Baseline values of hs-Troponin-I and NT-proBNP were significantly higher in patients who developed cardiotoxicity compared to those who did not, with a similar pattern observed at the 3-week follow-up. Receiver operating characteristic (ROC) curve analysis demonstrated that a cutoff value of baseline hs-Troponin-I > 11 ng/L, NT-proBNP > 90.1 pg/mL, 3-week left ventricular ejection fraction (LVEF) ≤ 52%, 3-week GLS ≥ − 14.5%, 3-week hs-Troponin-I > 13.1 ng/L, and 3-week NT-proBNP > 118.1 pg/mL predicted the occurrence of cardiotoxicity with high sensitivity (range 83–94%) and specificity (range 77–92%).
Conclusion
Combination of GLS with biomarkers had a high diagnostic value in early identification of anthracycline-related cardiac dysfunction, with an estimated diagnostic accuracy of over 85%. This information could potentially help in the identification of patients at high risk of developing cardiac dysfunction, allowing for earlier management.
