Abstract Purpose Cardiovascular reactivity to the cold pressor test (CPT) is considered to be a marker for apparent and potential hypertension. We aimed to elucidate the association between the changes in wave intensity (WI) during CPT and hypertension. Methods We recruited 85 volunteers, 33 of whom were hypertensive and 52 normotensive. Using ultrasonic equipment during CPT, we measured carotid arterial WI, which is defined in terms of blood pressure and velocity in the carotid artery. Results The peak WI (W1) increased during CPT in 70.6% of hypertensive individuals, but decreased in 72.6% of normotensive individuals. The chi-square (χ2) test showed that the association between the direction of change in W1 (increase or decrease) and the blood pressure (hypertensive or normotensive) was very strong (P < 0.0001). Conclusion Direction of change in W1 during CPT is a clear marker to discriminate cardiovascular reactivity that does not vary depending on each investigator’s subjective point of view.

Hypertension is one of the leading diseases of the cardiovascular system. It is manifested by changes in arterial stiffness. Cardiovascular reactivity, especially blood pressure (BP), changes during the cold pressor test (CPT) depending on various factors. Undoubtedly, stress is one of the most important factors. The aim of this study is to investigate the various effects of CPT on cardiovascular responses in healthy young subjects. A total of 56 healthy individuals aged between 21 and 26 years were investigated. The cardiovascular responses (BP, heart rate and aortic pulse wave velocity) to CPT were recorded by using the applanation tonometry. The Medical Outcomes Study Sleep Scale and the State-Trait Anxiety Inventory were used. 32.14% (n = 18) of the individuals who showed differences in systolic BP more than 22 mm Hg and differences in diastolic BP more than 18 mm Hg after the CPT were defined as hyperreactors. Hyperreactors showed a significantly higher increase in sleep disturbances (p > 0.01) and anxiety when compared to normoreactors. The CPT used to diagnose cardiovascular reactivity in young individuals and the assessment of perceived stress can help identify candidates who are at risk of hypertonic disease in the future.   Keywords: Cold pressor test, cardiovascular reactivity, applanation tonometry, blood pressure, stress.
