Intersection of Tyrosine Kinase Inhibition and Sepsis-Induced Cardiomyopathy

This case details a 78-year-old male with a history of old myocardial infarction and chronic myeloid leukemia treated with tyrosine kinase inhibitors (TKIs). The patient presented with exertional dyspnea and was hospitalized for congestive heart failure. Following the development of a urinary tract infection, the patient exhibited signs of sepsis-induced cardiomyopathy (SIC), including myocardial injury and rapid hemodynamic deterioration, leading to death. Autopsy findings indicated SIC, characterized by neutrophil-dominant inflammatory cell infiltration and endothelial damage, which might have been exacerbated by the patient's preexisting conditions of old myocardial infarction and TKI therapy. This case underscores the multifactorial nature of SIC, suggesting that preexisting old myocardial infarction and TKI therapies can significantly impact the disease's pathogenesis and progression. It highlights the need for comprehensive management strategies in patients with complex medical histories and the importance of further research to elucidate the underlying mechanisms of SIC.
