[Correlation between Haemostatic and Vegetate Nervous System Parameters under Examination Stress]

Area of Science:

• Physiology
• Autonomic Nervous System
• Cardiovascular System
• Hemostasis

Background:

• Examination stress is a common challenge for students, potentially affecting physiological systems.
• Understanding the interplay between the autonomic nervous system, cardiovascular function, and hemostasis during stress is crucial.

Purpose of the Study:

• To assess the correlation between autonomic nervous system (ANS) tone and the reactivity of the cardiovascular and hemostasis systems in students under examination stress.
• To identify physiological markers indicative of examination stress.

Main Methods:

• Assessment of autonomic nervous system tone through heart rate variability (HRV) analysis.
• Monitoring of cardiovascular parameters including respiration rate, tidal volume, and respiratory minute volume.
• Evaluation of hemostasis system markers such as trombocrite, platelet count and volume, prothrombin time, and thrombosis rate.

Main Results:

• Students under exam stress exhibited increased respiration rate and decreased tidal volume, leading to reduced respiratory minute volume in males, suggesting increased parasympathetic nervous system tone.
• Heart rate variability analysis showed a significant increase in fast wave power in both male and female students, indicating vagus nerve activation and serving as a marker for exam stress.
• Exam stress led to decreased trombocrite values. Female students showed a significant reduction in platelet count and an increase in platelet volume, alongside a higher initial thrombosis rate.
• Male students demonstrated an increase in prothrombin time under examination stress.

Conclusions:

• Examination stress activates the parasympathetic nervous system, evidenced by changes in respiratory patterns and heart rate variability.
• The hemostasis system is significantly altered by exam stress, with sex-specific differences observed in platelet parameters and clotting times.
• HRV and specific hemostasis markers can serve as reliable indicators of examination stress in students.
