Cardiotoxicity linked with hematopoietic stem cell transplantation (HSCT) is a well-described phenomenon associated

 

ABSTRACT

Cardiotoxicity linked with hematopoietic stem cell transplantation (HSCT) is a well-described phenomenon associated with an increased mortality risk; however, the majority of cardiac events present over 100 days following transfusion and are often attributed to graft-versus-host disease or pre-treatment conditioning by chemotherapy with or without radiation therapy. Here, we present the case of a 60-year-old female with a medical history of chronic lymphocytic leukemia complicated by a myelodysplastic syndrome that progressed to acute myeloid leukemia who developed chest pain immediately following an allogeneic HSCT. Electrocardiogram showed dynamic ST-depressions in leads V3-5 without evidence of reciprocal changes. Transthoracic echocardiography revealed pericardial effusion without signs of tamponade. The patient was thought to have acute pericarditis and was subsequently treated with high-dose intravenous methylprednisolone with a taper for two weeks. Her symptoms promptly subsided, and the pericardial effusion resolved on repeat echocardiography, which confirmed the diagnosis. Acute pericarditis is a rarely described complication of HSCT that is fatal if left untreated and prompts urgent management. This atypical case of acute pericarditis in the early post-transplant phase highlights the importance of cardiac stratification in patients with active malignancy undergoing treatment. It would suggest a potential benefit in closely monitoring high-risk individuals who have a history of coronary artery disease, smoking, or pericarditis in the pre-engraftment phase of transplantation.
