How I Approach Optimization of Patients at Risk of Cardiac and Pulmonary Complications After CAR T-cell Therapy

Chimeric antigen receptor (CAR) T cells have transformed the care for patients with hematologic malignancies. Patients treated with CAR T cells may experience cardiovascular and pulmonary complications, which primarily occur in the setting of cytokine release syndrome. In addition, many patients considered for CAR T-cell therapy have preexisting cardiac and pulmonary comorbidities. Among patients with good functional status, these conditions should not prevent patients from being offered these lifesaving therapies. In this article, we use a case-based approach to discuss how we evaluate and optimize conditions for patients with cardiac and pulmonary risk factors before CAR T-cell therapy and manage cardiac and pulmonary complications that may arise with treatment.
