AI Article Synopsis

  • Human pericardial fluid (PF) contains biologically active markers that have significant effects on heart-related cellular activities.
  • PF can enhance the activity of cardiac fibroblasts, which are important for heart tissue repair, through a specific biological pathway known as the transforming growth factor-β pathway.
  • In patients with coronary artery disease, the PF possesses a higher capacity to promote fibrosis compared to those without the disease, indicating a potential area for clinical attention.

Article Abstract

Human pericardial fluid (PF) is a rich reservoir of biologically active markers. The acellular compartment of PF can drive cardiac fibroblast activity in vitro. This process is mediated through the transforming growth factor-β pathway. Of clinical importance, the PF of patients with coronary artery disease has an increased profibrotic capacity compared with the PF of patients without coronary artery disease.
