Assessment of late cardiomyopathy by magnetic resonance imaging in patients with acute promyelocytic leukaemia treated with all-trans retinoic acid and idarubicin

Late cardiomyopathy CMP is regarded as a potential severe long-term complication after anthracycline-based regimens for acute promyelocitic leukaemia (APL). We assess by MRI the incidence and severity of clinical and subclinical long-term CMP in a cohort of adult APL patients in first complete remission with PETHEMA trials. Adult patients diagnosed with APL in first complete remission lasting ≥2 years underwent anamnesis and physical examination and were asked to perform a cardiac MRI. Clinical CMP was defined as radiographic and physical signs of heart failure accompanied by symptoms or by left ventricle ejection fraction (LVEF)
