Plasma fibrinogen--a major coronary risk factor

|December 1, 1985
Summary
High plasma fibrinogen levels significantly increase heart attack risk, independent of other factors. This finding highlights fibrinogen as a crucial coronary risk indicator for identifying individuals susceptible to myocardial infarction.
Area of Science:
- Cardiology
- Hematology
- Epidemiology
Background:
- Coronary heart disease (CHD) remains a leading cause of mortality worldwide.
- Identifying reliable indicators of heart attack susceptibility is crucial for preventive strategies.
- Plasma fibrinogen's role as a cardiovascular risk marker requires further elucidation.
Purpose of the Study:
- To investigate the association between plasma fibrinogen levels and the incidence of heart attacks in men without pre-existing CHD.
- To determine if plasma fibrinogen is an independent predictor of heart attack risk.
Main Methods:
- A cohort of 297 men aged 40-69, free from overt CHD at baseline, was observed.
- Plasma fibrinogen levels were measured at the start of the study.
- Follow-up averaged 7.3 years to record new heart attacks.
Main Results:
- A significant positive correlation was observed between initial plasma fibrinogen levels and subsequent heart attack incidence.
- Men with high fibrinogen had a substantially higher heart attack risk, especially when combined with high cholesterol or blood pressure.
- Plasma fibrinogen emerged as a significant and independent predictor of heart attacks, comparable in importance to cholesterol, blood pressure, and smoking.
Conclusions:
- Elevated plasma fibrinogen is a significant independent risk factor for heart attacks.
- Plasma fibrinogen levels should be incorporated into risk assessment profiles for identifying individuals at high risk of myocardial infarction.

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...
Extrinsic and Intrinsic Pathways of Hemostasis
Blood clotting or coagulation involves extrinsic and intrinsic pathways, which ultimately merge into the common pathway, forming a fibrin clot.
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which forms a...

Clot Retraction and Fibrinolysis
After a fibrin clot is formed, the next step is clot retraction, a vital process facilitated by platelet contractile proteins, such as actin and myosin. These proteins pull the fibrin strands closer together and condense the clot. This action reduces the size of the clot, creating a smaller, denser structure that effectively seals off the damaged vessel. Clot retraction consolidates the clot and helps with wound healing by bringing the edges of the damaged blood vessel closer together.
Coronary Artery Disease I: Introduction
Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...
Coronary Artery Disease II: Pathophysiology
Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...
Coronary Artery Disease IV: Preventive Measures
Effective preventive measures for coronary artery disease (CAD) focus on controlling modifiable risk factors, including cholesterol abnormalities and lifestyle changes.Cholesterol ManagementFirst, the Mediterranean diet and the American Heart Association advocate for maintaining low-density lipoprotein (LDL) cholesterol levels below 100 mg/dL, with a more stringent recommendation of below 70 mg/dL for individuals at high risk. LDL cholesterol, often termed "bad cholesterol," can lead to the...
