About

Sepsis cardiac insufficiency is characterized by high morbidity and mortality. Studies have shown an association between elevated PLA levels in patients with sepsis and clinical outcomes of cardiac dysfunction. This study will explore the correlation between circulating PLA levels and organ dysfunction and disease severity in SIMD patients in the form of a cross-sectional study.

Full description

Sepsis cardiac insufficiency is an unsolved problem in the field of severe disease, which is characterized by high morbidity and high mortality. Several studies have found that infectious factors activate platelets and inflammatory cells, damage the vascular endothelium, and cause leukocytes to interact with platelets to form platelet-leukocyte aggregates, and elevated PLA levels in patients with sepsis are associated with the clinical outcome of cardiac dysfunction. The literature studies have shown that the serum PLA level in sepsis patients is significantly increased, and the PLA level is positively correlated with the severity of cardiac dysfunction in sepsis patients, and the formation of PLA is regulated by the binding of CD62P on the surface of activated platelets and PSGL-1 on the surface of leukocytes. This study will explore the correlation between circulating PLA levels and organ dysfunction and disease severity in patients with SIMD in the form of a cross-sectional study, in order to provide a new potential direction for the evaluation and treatment of SIMD.
