CAR-T Therapy in Lymphoma Patients With Coexisting Cardiomyopathy or Cardiac Lymphomatous Involvement.

Chimeric antigen receptor T-cell (CAR-T) therapy has revolutionized the management of aggressive hematologic malignancies. However, its role in patients with lymphoma and cardiac metastasis or cardiomyopathy remains undefined due to potentially life-threatening complications such as ventricular rupture, cardiac tamponade, and circulatory failure. We present a case series of patients with lymphoma and cardiomyopathy or cardiac metastasis managed with chimeric antigen receptor T-cell therapy.

PET Imaging in Cardiac Sarcoidosis: A Narrative Review with Focus on Novel PET Tracers.

Sarcoidosis is a multi-system inflammatory disease characterized by the development of inflammation and noncaseating granulomas that can involve nearly every organ system, with a predilection for the pulmonary system. Cardiac involvement of sarcoidosis (CS) occurs in up to 70% of cases, and accounts for a significant share of sarcoid-related mortality. The clinical presentation of CS can range from absence of symptoms to conduction abnormalities, heart failure, arrhythmias, valvular disease, and sudden cardiac death.

Myocarditis Following Coronavirus Disease 2019 mRNA Vaccine: A Case Series and Incidence Rate Determination.

Background: Myocarditis following coronavirus disease 2019 (COVID-19) mRNA vaccines (Pfizer-BioNTech and Moderna) has been increasingly reported. Incidence rates in the general population are lacking, with pericarditis rather than myocarditis diagnostic codes being used to estimate background rates. This comparison is critical for balancing the risk of vaccination with the risk of no vaccination.

Senolytic agents lessen the severity of abdominal aortic aneurysm in aged mice.

Age is a major risk factor for abdominal aortic aneurysm (AAA), for which treatment options are limited to surgical intervention for large AAA and watchful waiting for small aneurysms. However, the factors that regulate the expansion of aneurysms are unclear. Development of new therapeutic strategies to prevent or treat small aneurysms awaits a more thorough understanding of the etiology of AAA formation and progression with aging.

Cardio Phenotypic Potential of Mesenchymal Stem Cells.

Cell therapy is being investigated as a powerful intervention to ameliorate the consequences of coronary artery disease. Among the different stem cell options, mesenchymal stem cells (MSCs) are particularly attractive due to their high availability, as well as immune-privileged status. However, it is still unclear whether mesenchymal stem cells can acquire cardiomyogenic characteristics after they are transplanted to the myocardium.
