AI Microscope Tracks Platelet Clotting in Heart Patients
Updated May 31, 2025
A team at the University of Tokyo has developed a non-invasive method to observe blood clotting activity using a novel microscope and artificial intelligence (AI). The study focuses on tracking platelet clumping in patients with coronary artery disease (CAD),potentially leading to safer,more personalized treatment strategies for heart disease and stroke prevention.
Platelets, essential for stopping bleeding, can sometimes form perilous clots in arteries, especially in individuals with heart conditions. Dr.Kazutoshi Hirose, assistant professor at the University of Tokyo Hospital, noted the difficulty in accurately evaluating the effectiveness of antiplatelet drugs, a common treatment for CAD. This challenge spurred the progress of the new monitoring system.
The innovative system employs a frequency-division multiplexed (FDM) microscope, described by co-author Yuqi Zhou as a “super high-speed camera” that captures rapid images of blood cells. AI than analyzes these images to identify single platelets, platelet clumps, and even white blood cells interacting with the platelets. This allows researchers to track platelet aggregation, a key indicator of clotting risk, in real time.
The team analyzed blood samples from over 200 patients, revealing that those with acute coronary syndrome exhibited more platelet aggregates compared to those with chronic symptoms. This finding supports the technology’s ability to monitor clotting risk effectively.
According to dr. Keisuke Goda, who led the research team, advances in high-speed imaging and AI have enabled the observation and analysis of blood cells in motion in unprecedented ways. The AI can detect patterns that are invisible to the human eye,providing valuable insights into platelet behavior.
Notably, the study found that a standard blood sample drawn from the arm provided almost the same facts as samples obtained through invasive procedures directly from the heart’s arteries. this significantly simplifies and reduces the risks associated with monitoring platelet activity.
“What we found is that just taking a regular blood sample from a vein in the arm can still provide meaningful information about platelet activity in the arteries. That’s exciting as it makes the process much easier, safer and more convenient,” Hirose said.
The researchers hope this technology will enable doctors to personalize heart disease treatment by tailoring antiplatelet drug dosages to individual patient needs. The AI-powered microscope offers a new way to monitor platelet activity and improve outcomes for those at risk of heart attack and stroke, offering a new approach to coronary artery disease (CAD) management.
What’s next
The research team plans to conduct further studies to refine the technology and explore its potential applications in other areas of medicine, with the goal of improving patient care through personalized treatment strategies based on real-time monitoring of platelet activity.
