Insights
Arterial tonometry and vascular calcification are linked to cardiovascular disease risk. This study found associations between arterial measures, platelet function, and calcification, suggesting interconnectedness in atherosclerosis development.
Area of Science:
- Cardiovascular Medicine
- Vascular Biology
- Platelet Physiology
Background:
- Arterial tonometry and vascular calcification are established cardiovascular disease (CVD) risk assessment tools.
- Prior research indicates associations between arterial measures, calcification, and CVD risk.
- Platelet activation and angiopoietin-1 release may link vascular structure and platelet function.
Purpose of the Study:
- To investigate the relationship between arterial tonometry measures, platelet function, and vascular calcification.
- To explore potential connections between vascular structure (aorta diameter) and platelet reactivity.
- To analyze these associations within the Framingham Heart Study cohorts.
Main Methods:
- Analysis of arterial tonometry, platelet function (5 assays, 7 agonists), and calcification (aortic, thoracic, coronary) in 3,429 participants.
- Measurement of thoracic and abdominal aorta diameters.
- Linear mixed effects models were used, adjusting for CVD risk factors and family structure.
Main Results:
- Higher arterial calcium trended with increased platelet reactivity.
- Larger aortic diameters trended with decreased platelet reactivity.
- Specific arterial tonometry measures showed mixed trends with platelet reactivity traits (e.g., Zc, pulse pressure, pulse wave velocity).
Conclusions:
- Vascular calcification and platelet activation appear interrelated in subclinical atherosclerosis.
- Aortic diameter trends suggest lower shear environments may reduce platelet reactivity.
- While trends were observed, results did not meet stringent multiple test correction thresholds.
Abstract:
Arterial tonometry and vascular calcification measures are useful in cardiovascular disease (CVD) risk assessment. Prior studies found associations between tonometry measures, arterial calcium, and CVD risk. Activated platelets release angiopoietin-1 and other factors, which may connect vascular structure and platelet function. We analyzed arterial tonometry, platelet function, aortic, thoracic and coronary calcium, and thoracic and abdominal aorta diameters measured in the Framingham Heart Study Gen3/NOS/OMNI-2 cohorts (n = 3,429, 53.7% women, mean age 54.4 years ±9.3). Platelet reactivity in whole blood or platelet-rich plasma was assessed using 5 assays and 7 agonists. We analyzed linear mixed effects models with platelet reactivity phenotypes as outcomes, adjusting for CVD risk factors and family structure. Higher arterial calcium trended with higher platelet reactivity, whereas larger aortic diameters trended with lower platelet reactivity. Characteristic impedance (Zc) and central pulse pressure positively trended with various platelet traits, while pulse wave velocity and Zc negatively trended with collagen, ADP, and epinephrine traits. All results did not pass a stringent multiple test correction threshold (p < 2.22e-04). The diameter trends were consistent with lower shear environments invoking less platelet reactivity. The vessel calcium trends were consistent with subclinical atherosclerosis and platelet activation being inter-related.

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...
