[Effects on platelet functions].

E Jacobi, O Richter, G Krüskemper

    Fortschritte Der Medizin
    |February 15, 1979
    PubMed
    Summary

    Stressful events increase platelet adhesiveness, a risk factor for cardiovascular conditions like heart failure and thrombosis. This heightened platelet activity is observed in patients with these conditions and healthy individuals exposed to stressors.

    Area of Science:

    • Biomedical Science
    • Hematology
    • Cardiovascular Research

    Context:

    • Platelet adhesiveness plays a crucial role in hemostasis and thrombosis.
    • Altered platelet function is implicated in various cardiovascular and thrombotic diseases.
    • Understanding factors influencing platelet adhesiveness is vital for risk assessment.

    Purpose:

    • To investigate platelet adhesiveness in healthy volunteers and patients with specific cardiovascular and thrombotic conditions.
    • To evaluate the in vivo impact of stressors on platelet adhesiveness.
    • To determine if stressors represent a risk factor in individuals with compromised vessel walls.

    Summary:

    • A study involving 589 participants measured platelet adhesiveness.
    • Patients with heart failure, diabetes mellitus, myocardial infarction, and deep vein thrombosis exhibited significantly higher platelet adhesiveness compared to healthy volunteers.
    • In vivo exposure to stressors replicated the elevated platelet adhesiveness seen in patients, indicating stressors' significant impact.

    Impact:

    • Findings suggest that stressors are a significant risk factor for individuals with pre-existing vascular wall alterations.
    • This research highlights the importance of managing stress in cardiovascular and thrombotic disease prevention and management.
    • The study provides evidence linking physiological stress to increased thrombotic risk via enhanced platelet activity.
