Cold Pressor Test in Borderline Hypertensive University Students

Area of Science:

• Cardiovascular Physiology
• Hypertension Research
• Preventive Medicine

Background:

• Hyperactive sympathetic responses contribute to hypertension development in young individuals.
• Exaggerated cardiovascular reactivity to stress in youth predicts future blood pressure elevation.
• Understanding cardiovascular reactivity is crucial for early hypertension risk assessment.

Purpose of the Study:

• To assess cardiovascular reactivity using the cold pressor test.
• To correlate cardiovascular reactivity with smoking, family history, and physical activity.
• To identify early markers for hypertension development in young adults.

Main Methods:

• Recruited normotensive and prehypertensive volunteers.
• Measured resting blood pressure using a sphygmomanometer.
• Administered a cold pressor test (10°C water immersion) and monitored blood pressure changes.

Main Results:

• Both normotensive and prehypertensive groups showed significant blood pressure increases post-cold pressor test.
• Prehypertensive individuals exhibited less sharp blood pressure recovery compared to normotensive individuals.
• Prehypertensive smoking males displayed a significant rise and delayed recovery in diastolic blood pressure.

Conclusions:

• Prolonged blood pressure elevation post-stress indicates future hypertension risk in young individuals.
• Cardiovascular reactivity to cold pressor test serves as a potential hypertension marker.
• Adopting a healthy lifestyle may delay the onset of hypertension.
