Key result
A cold pressor test elevated blood pressure in both angiography and adrenalectomised patients, but plasma catecholamines only rose significantly in those with intact adrenal glands.
Why the study?
Does the blood pressure elevation in response to a cold pressor test depend on adrenal medullary catecholamine release?
Population
10 patients undergoing coronary angiography and 2 adrenalectomised volunteers (n=12 total).

Cold pressor test raises catecholamines in angiography patients; leaves open adrenal contribution in this small cohort.
Observational (n=12)
Does the blood pressure elevation in response to a cold pressor test depend on adrenal medullary catecholamine release?
Blood pressure elevation during a cold pressor test appears to be independent of adrenal medullary catecholamine release.
Cummings et al. (1983) conducted an observational in Patients undergoing coronary angiography and adrenalectomised volunteers (n=12). Cold pressor test vs. Adrenalectomised volunteers / Baseline was evaluated on Plasma catecholamine levels (dopamine, adrenaline, noradrenaline) and arterial blood pressure. A cold pressor test elevated blood pressure in both angiography and adrenalectomised patients, but plasma catecholamines only rose significantly in those with intact adrenal glands.
