[Effect of emotional tension on intravascular coagulation in patients with angiographically established ischemic
Insights
Simulated emotional stress (ES) worsens blood clotting in coronary patients. Stress increases thrombogenic potential, leading to more intravascular coagulation in these individuals.
Area of Science:
- Cardiovascular Science
- Hemostasis Research
- Stress Physiology
Background:
- The hemostatic system is crucial for blood clotting.
- Coronary patients often exhibit pre-existing hemostatic disturbances.
- Emotional stress can impact physiological systems.
Purpose of the Study:
- To investigate the impact of simulated emotional stress (ES) on hemostasis.
- To compare the effects of ES in normal subjects versus coronary patients.
- To identify specific hemostatic markers affected by ES in coronary patients.
Main Methods:
- Simulated emotional stress (ES) was administered to participants.
- Platelet/vascular and plasma components of the hemostatic system were analyzed.
- Key markers including cAMP/cHMP ratio, soluble fibrin, fibrinogen-fibrin degradation products (FDPs), and antithrombin III were measured.
Main Results:
- Coronary patients displayed pre-existing hemostatic abnormalities and a tendency towards intravascular coagulation.
- ES significantly increased the thrombogenic potential in coronary patients.
- Declining cAMP/cHMP ratio, increased FDPs, and reduced antithrombin III indicated enhanced intravascular coagulation post-stress.
Conclusions:
- Emotional stress exacerbates the pro-thrombotic state in coronary patients.
- Hemostatic system alterations under stress highlight a heightened risk of coagulation disorders.
- Findings suggest stress management may be important for coronary patient care.
Abstract:
The effect of simulated emotional stress (ES) on the platelet/vascular and plasma components of the hemostatic system was examined in normal subjects and coronary patients. In coronary patients, prestress hemostatic platelet/vascular and plasma factors were disturbed, their blood showing a tendency to activated intravascular coagulation. Stress further increased the blood thrombogenic potential of coronary patients, causing intravascular coagulation as evidenced by declining cAMP/cHMP ratio, enhanced release of soluble fibrin and fibrinogen-fibrin degradation products (FDPs), and reduced antithrombin III.
