Understanding the dynamics of platelet aggregation is fundamental to the formulation of antithrombotic treatments that can reduce morbidity rates associated with cardiovascular diseases. A recent study, supported by a microfluidics platform emulating a thrombogenic stenosis in an environment independent of chemical pathways and under non-recirculating conditions, has revealed the primary role of hemodynamics to initiate platelet aggregation. We identify four distinct stages in the thrombus growth present in such a platform, and formulate an explanatory physical model of the relationship between the hemodynamics and thrombus growth. This model provides insight into the mechanistic variables regulating platelet aggregation.
