What is the incidence of cardiotoxic effects associated with CAR-T therapy in adults with hematologic malignancies?
CAR-T cell therapy is associated with a nearly 20% incidence of cardiovascular events, emphasizing the need for vigilant cardiovascular monitoring, particularly in patients with pre-existing cardiovascular conditions.
BACKGROUND: Chimeric antigen receptor T-cell (CAR-T) therapy has shown promise in treating hematologic malignancies, yet its potential cardiotoxic effects require thorough investigation. OBJECTIVES: We aim to conduct a systematic review and meta-analysis to examine the cardiotoxic effects of CAR-T therapy in adults with hematologic malignancies. METHODS: We searched PubMed, Embase, and the Cochrane Central Register of Controlled Trials for studies reporting cardiovascular outcomes, such as arrhythmias, heart failure, and reduced left ventricle ejection fraction (LVEF). RESULTS: Our analysis of 20 studies involving 4789 patients revealed a 19.68% incidence rate of cardiovascular events, with arrhythmias (7.70%), heart failure (5.73%), and reduced LVEF (3.86%) being the most prevalent. Troponin elevation was observed in 23.61% of patients, while NT-Pro-BNP elevation was observed in 9.4. Subgroup analysis showed higher risks in patients with pre-existing conditions, such as atrial arrhythmia (OR 3.12; p < .001), hypertension (OR 1.85; p = .002), previous heart failure (OR 3.38; p = .003), and coronary artery disease (OR 2.80; p = .003). CONCLUSION: Vigilant cardiovascular monitoring is crucial for patients undergoing CAR-T therapy to enhance safety and treatment efficacy.Novelty Statements.
