As demonstrated in post-infarction patients, the combined treatment with an ACEI and carvedilol could have additive effects to prevent LV dysfunction in patients with hematological malignancies at high risk of cardiac toxicity. Therefore, we designed the OVERCOME (preventiOn of left Ventricular dysfunction with Enalapril and caRvedilol in patients submitted to intensive ChemOtherapy for the treatment of Malignant hEmopathies) study, a prospective, randomized trial to evaluate the combined effect of enalapril and carvedilol on the prevention of left ventricular dysfunction in patients with malignant hemopathies undergoing intensive chemotherapy.
