Abstract

INTRODUCTION: Some of the chemotherapeutics can inflictthe cardiac damage, especially anthracyclines. In our study weevaluate to effect of anthracyclines on frontal QRS‐T angle inpatients with leukemia.METHODS: A total of 39 leukemia patients who takeanthracyclines were included in this retrospective study. Allpatients underwent 12‐lead surface electrocardiograms(ECGs) and echocardiography just before and after theanthracyclines. 14 patients were taken doxorubicin and 25patients were taken idarubicin. QT interval, QTc interval, Tp‐einterval, Tp‐e/QT, Tp‐e/QTc and frontal QRS‐T angle werecalculated from 12‐lead ECGs.RESULTS: In all, 39 patients(23% females) were enrolled inour study. Mean age of patients is 40 ±15 years. QT interval(360 ± 32 vs. 368 ± 27.1, P = 0.161), QTc interval (400 ± 6.4vs. 404 ± 20, P = 0.276), Tp‐e interval (80.17 ± 14.2 vs. 84.3 ±13 P = 0.248). More importantly, frontal QRS‐T angle (17.5±17 vs. 16.5 ±14, P = 0.692) was not significantly before andafter chemotherapy. In addition, Tp‐e/QT (0.22 ± 0.04 vs. 0.23± 0.04, P = 0.543) and Tp‐e/QTc (0.20 ± 0.03 vs. 0.20 ± 0.04,P = 0.313) were not significantly changed after chemotherapy.When we made subgroup analysis we found same results.DISCUSSION AND CONCLUSION: Both doxorubicin andepirubicin-based chemotherapy did not change the ECGparameter in early phase because of the lower dose. They canbe used safely in patient with leukemia.

Özet

GİRİŞ ve AMAÇ: Bazı kemoterapötikler özelikle de antrasiklinlerin kalbe zararlı etkileri olabilir. Biz bu çalışmamız da lösemi hastalarında kemoterapötiklerin frontal QRS‐T açısı üzerine etkisini değerlendirmeyi amaçladık. YÖNTEM ve GEREÇLER: Toplam 39 antrasiklin alan lösemi hastası bu retrospektif çalışmada yer aldı. Bütün hastalara antrasiklin öncesi ve sonrası 12 lead elektrokardiografi (EKG) ve ekokardiyografi çekilenler çalışmaya dahil edildi.14 hasta doxorubicin, 25 hasta da idarubicin alıyordu. Bütün hastaların. QT interval, QTc interval, Tp‐e interval, Tp‐e/QT, Tp‐e/QTc ve frontal QRS‐T açıları 12 lead EKG üzerinden hesaplandı BULGULAR: Çalışmamız toplam 39 hastadan (%23 kadın) oluşmaktadır. Hastaların ortalama yaşı 40 ±15 di. QT interval (360 ± 32 vs. 368 ± 27.1, P = 0.161), QTc interval (400 ± 6.4 vs. 404 ± 20, P = 0.276), Tp‐e interval (80.17 ± 14.2 vs. 84.3 ± 13 P = 0.248). Daha da önemlisi frontal QRS‐T angle (17.5 ±17 vs. 16.5 ±14, P = 0.692) değerinin kemoterapi öncesi ve sonrası arasında fark izlenmedi. Ek olarak Tp‐e/QT (0.22 ± 0.04 vs. 0.23 ± 0.04, P = 0.543) and Tp‐e/QTc (0.20 ± 0.03 vs. 0.20 ± 0.04, P = 0.313) değeride kemoterapi sonrası değişmedi. Alt grup analizinde de benzer sonuçlar elde ettik. TARTIŞMA ve SONUÇ: Hem doxorubicin hem de epirubicin temelli kemoterapi erken fazda düşük doz kullanıldığından dolayı EKG parametrelerini değiştirmedi. Antrasiklinleri güvenli bir biçimde lösemi hastalarına kullanabiliriz.
