Authors' conclusion

In patients with isolated GLS reduction after anthracyclines, cardioprotection is associated with better preservation of 12-month MRI-LVEF compared with usual care.

Study context

Population
Patients receiving anthracyclines with normal baseline left ventricular ejection fraction (LVEF), ≥1 other cancer therapy-related cardiac dysfunction (CTRCD) risk factor, developing GLS-CTRCD (>12% relative global longitudinal strain (GLS) reduction without LVEF change)randomised of 333 tracked
Participants
105 patients
