Insights
Aging platelets contribute to dangerous blood clots in elderly patients with cardiovascular disease and COVID-19. Understanding platelet aging and aggregation is key for early antiplatelet therapy.
Area of Science:
- Gerontology
- Hematology
- Infectious Diseases
Background:
- Thrombotic reactions are a significant concern in the elderly, particularly with cardiovascular diseases.
- New data is emerging on hemostatic system changes, including platelet and plasma levels, in patients with COVID-19.
Purpose of the Study:
- To review pathophysiological platelet reactions during aging.
- To explore mechanisms of pathological platelet aggregation.
- To inform discussions on early antiplatelet therapy for cardiovascular diseases and COVID-19.
Main Methods:
- Literature review of fundamental and clinical data.
- Synthesis of information on platelet aging and aggregation.
- Analysis of hemostatic system changes in COVID-19 patients.
Main Results:
- Platelet aging is associated with thrombotic reactions.
- Pathological aggregation mechanisms in aging platelets are being elucidated.
- COVID-19 impacts the hemostatic system, involving platelets.
Conclusions:
- Understanding platelet aging and aggregation is crucial for managing thrombotic risks.
- Early antiplatelet therapy may be beneficial for cardiovascular patients and those with COVID-19.
- Further research is needed to fully understand platelet roles in COVID-19 and aging.
Abstract:
The development of thrombotic reactions that lead to undesirable clinical consequences in the elderly is known in many diseases, including pathology of the cardiovascular system. Today, data on the severity of changes in the hemostatic system in patients with a new coronavirus infection (COVID-19) and the study of platelet and plasma levels are being accumulated. In order to understand some of the mechanisms associated with platelet pathology, we present a review that summarizes information about the pathophysiological reactions of platelets in the conditions of their aging and possible mechanisms of their pathological aggregation. Perhaps the presented fundamental and clinical data will be of interest to a wide audience of specialists to discuss early antiplatelet therapy and its justification not only in patients with cardiovascular diseases, but also with COVID-19.

Inflammation
Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
Structure and Function of Platelets
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000...
