Summary
Most acute ischemic events stem from thrombosis on disrupted plaques. Researchers are investigating novel hemostatic risk factors beyond traditional atherosclerosis markers to understand these events better.
Area of Science:
- Cardiovascular Medicine
- Hematology
- Genetics
Background:
- Acute ischemic syndromes and sudden cardiac death are often triggered by thrombosis on disrupted atherosclerotic plaques.
- A notable proportion of these events occur in individuals lacking conventional atherosclerosis risk factors, suggesting other contributing elements.
- Understanding these additional factors is crucial for comprehensive risk assessment and prevention strategies.
Purpose of the Study:
- To identify and discuss potential hemostatic risk factors contributing to acute ischemic events.
- To explore the evidence linking these factors to atherothrombotic events, particularly in individuals without traditional risk factors.
- To examine the role of the thrombotic cascade, cellular components, plasma proteins, and genetic polymorphisms in atherothrombosis.
Main Methods:
- Review and synthesis of existing research on hemostatic factors and atherothrombotic events.
- Examination of the thrombotic cascade and its cellular and molecular components.
- Analysis of genetic polymorphisms associated with hemostatic pathways.
- Discussion of evidence linking specific hemostatic risk factors to clinical outcomes.
Main Results:
- Thrombosis on disrupted plaques is a primary cause of acute ischemic events.
- Several hemostatic factors, including genetic variations, are implicated as potential risk factors.
- Evidence links these factors to atherothrombotic events, even in the absence of traditional risk factors.
- The thrombotic system's components and their genetic makeup play a significant role.
Conclusions:
- Hemostatic factors represent important, often overlooked, risk factors for acute ischemic events.
- Further research into these factors can improve the identification and management of individuals at risk.
- Genetic polymorphisms within the hemostatic system may offer novel insights into atherothrombotic disease susceptibility.

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...
01:30Venous Thrombosis I: Introduction
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...
01:24Disorders of Hemostasis
Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.

01:19Pulmonary Embolism I: Introduction
A blood clot, or thrombus, is a semi-solid mass composed of fibrin, platelets, and red blood cells. When it forms within a vessel, it can obstruct blood flow, known as thrombosis. If part of the clot detaches, it becomes an embolus that can travel and block distant vessels. When this occurs in the pulmonary arteries, it causes a condition known as pulmonary embolism (PE).Origin and ImpactMost often, the embolus originates from a thrombus in the deep veins of the lower limbs, a condition called...
01:29Pulmonary Embolism I: Introduction
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...
01:29Venous Thrombosis III: Interprofessional Care
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
