Inflammation from tissue injury alters blood flow (haemodynamics) by changing blood properties. New research explores fibrinogen

Area of Science:

  • Biomedical Engineering
  • Physiology
  • Pathology

Background:

  • Tissue injury triggers an inflammatory response, involving vascular and cellular changes.
  • Inflammation impacts blood rheology, affecting haemodynamics through altered resistance.
  • Systemic effects of inflammation can lead to detrimental haemodynamic changes.

Purpose of the Study:

  • To investigate the impact of inflammation on blood rheology and haemodynamics.
  • To explore novel mechanisms influencing blood flow during inflammation, specifically fibrinogen heterogeneity and leucocyte protease release.

Main Methods:

  • Review of existing literature on inflammation, haemodynamics, and blood rheology.
  • Analysis of the potential roles of fibrinogen heterogeneity and leucocyte proteases.

Main Results:

  • Inflammation-induced changes in vascular and plasma protein concentrations, like fibrinogen, alter blood viscosity.
  • Leukocyte activity and protease release may affect red blood cell aggregation.
  • These rheological changes contribute to both beneficial local and potentially harmful systemic haemodynamic alterations.

Conclusions:

  • Inflammation significantly impacts blood rheology and haemodynamics.
  • Fibrinogen heterogeneity and leucocyte protease release represent new areas of investigation for understanding inflammation-related haemodynamic dysfunction.
