Clot is a blood response
A clot forms when the blood-clotting system is activated. After plaque rupture, clotting can quickly reduce or block blood flow.
Risk Atlas · clot
How a clot can form at a rupture site and reduce blood flow.
This risk atlas picks up where the Rupture atlas stops: exposed plaque contents are already in contact with flowing blood. It shows how platelets, clotting proteins, and a growing thrombus can turn a surface injury into a blood-flow problem. Use the slider to move from exposure to platelet attachment, fibrin mesh formation, clot growth, and severe flow reduction.

Key information
Clot: what to understand
Platelets are central
Platelets can stick, activate, and recruit more clotting activity. That is why antiplatelet medicines exist for selected clinical situations.
Flow loss drives danger
The immediate danger is not the clot itself in isolation. The danger is reduced oxygen delivery to heart or brain tissue.
Clot risk has layers
Plaque rupture, inflammation, blood factors, rhythm problems, procedures, and some inherited or acquired conditions can all affect clot context. The cause matters for treatment.
Different clots need different decisions
Artery clots and vein clots are not managed the same way. Heart attack, stroke, atrial fibrillation, and venous clots each need their own clinical pathway.
Treatment is not do-it-yourself
Antiplatelet and anticoagulant medicines can help in the right setting and harm in the wrong one. They should be used only when clinically appropriate.
Clot is not the same as plaque
Plaque is an artery-wall process; clot is a blood process. They can connect, but they are not the same thing.
Blood thinners are not universal prevention
More clot prevention is not always better. Bleeding risk is part of the decision.
Symptoms that improve are still emergencies
Heart attack or stroke symptoms can fluctuate. Do not wait because symptoms ease or come and go.
Heart risk products
Clarify risks. Navigate dangers. Prevent events.
Clot is where a local plaque problem can become a blood-flow problem. If you want help understanding what your current heart risk checks do and do not show, start with Clarify. If you already have signals such as Lp(a), ApoB, inflammatory markers, blood pressure concerns, calcium-score findings, metabolic risk, or family history and want to understand how they may interact, Navigate may be right for you. If you want to reduce your — or a loved one’s — risk of heart attack, stroke, or avoidable cardiovascular damage, Prevent may be right for you.
