Novel factors affecting fibrin clot formation and their clinical implications.
Fibrin formation is pivotal in hemostasis, serving as a temporary barrier to blood loss following vascular injury, while in thrombosis this process is involved in thrombus progression, stability, and recurrence. Growing evidence shows an exceptional complexity of processes that determine fibrin clot structure and function, especially lysability, both in health and disease, which might be relevant in the pathogenesis of arterial and venous thromboembolic diseases. ⋯ These factors have been shown to be not only associated with ischemic stroke, myocardial infarction, pulmonary embolism, and cardiovascular death, but also with unfavorably altered fibrin clot characteristics, which underscores clinical relevance of fibrin clot properties. Given preclinical or ongoing studies aimed at modifying some of these factors, in particular FXI / FXIa inhibitors, recent findings might expand our knowledge on fibrin-related mechanisms of emerging therapeutic agents tested and stimulate further research into new targets for future therapeutic interventions to prevent thromboembolic events.
