Platelet activity and cardiovascular risk in apparently healthy individuals: a review of the data

Area of Science:

• Cardiovascular Medicine
• Hematology
• Biomarkers

Background:

• Cardiovascular disease (CVD) is a leading cause of death globally.
• Existing risk scores identify individuals at elevated CVD risk.
• The role of platelet activity in CVD pathogenesis and prediction remains unclear.

Purpose of the Study:

• To evaluate the association between various platelet activity measurements and the incidence of cardiovascular disease in healthy individuals.
• To determine the utility of platelet function tests in predicting future CVD events.

Main Methods:

• Review of existing literature on platelet function tests and CVD incidence.
• Discussion of platelet aggregometry, plasma markers (soluble CD40L, P-selectin), mean platelet volume, platelet count, and bleeding time.
• Emphasis on the need for large-scale, prospective studies.

Main Results:

• Data on platelet aggregation and CVD incidence is conflicting.
• Plasma markers like soluble CD40L and P-selectin show potential but require further investigation.
• Platelet count and bleeding time are not specific indicators of platelet activity or CVD risk in healthy populations.

Conclusions:

• Current evidence on platelet activity measurements for predicting cardiovascular disease incidence is inconclusive.
• Further large-scale, prospective research is essential to validate the predictive value of platelet function tests.
• Standardized measurement of a panel of platelet tests in well-defined cohorts is recommended for future studies.
