Key result
Mild hypertension was associated with greater increases in mean arterial blood pressure during cold pressor (10 vs 5 mmHg) and ischaemic handgrip tests (9 vs 3 mmHg) compared to normotension (P<0.05).
Why the study?
Do individuals with mild hypertension have an augmented cardiovascular response to sympathoexcitatory stress compared to normotensive individuals?
Population
66 participants aged 30-79 years with no history of taking antihypertensive medication, comprising…

Augmented BP reactivity to stress in mild hypertension may reflect early autonomic imbalance; leaves open prospective validation before clinical use.
Observational (n=66)
Do individuals with mild hypertension have an augmented cardiovascular response to sympathoexcitatory stress compared to normotensive individuals?
Absolute Event Rate: 10% vs 5%
p-value: p=<0.05
Individuals with mild hypertension exhibit an augmented blood pressure response to sympathoexcitatory stress and lower resting parasympathetic cardiac modulation compared to normotensive individuals.
Carthy et al. (2014) conducted an observational in Mild hypertension (n=66). Mild hypertension vs. Normal blood pressure was evaluated on Increase in mean arterial blood pressure during cold pressor test (p=<0.05). Mild hypertension was associated with greater increases in mean arterial blood pressure during cold pressor (10 vs 5 mmHg) and ischaemic handgrip tests (9 vs 3 mmHg) compared to normotension (P<0.05).
