Key result
Awareness of hypertension increased mean blood pressure by 11.5 mm Hg after 15 minutes sitting (P<0.01) and significantly increased heart rate and epinephrine responses to a cold pressor test.
Why the study?
Does awareness of hypertension increase blood pressure and sympathetic responses to a cold pressor test in young men with elevated blood pressure?
RCT (n=29)
Randomized
Does awareness of hypertension increase blood pressure and sympathetic responses to a cold pressor test in young men with elevated blood pressure?
p-value: p=<.01
Awareness of a hypertension diagnosis can acutely increase blood pressure and sympathetic reactivity, highlighting the psychological impact of diagnostic labeling.
No takes yet. Share an insight, caveat, or question.
Awareness of hypertension diagnosis acutely elevates BP and sympathetic reactivity; warrants caution with labeling and extends evidence on diagnostic psychological effects.
Rostrup et al. (1990) conducted an RCT in Elevated blood pressure (n=29). Letter informing of high blood pressure vs. Neutral letter was evaluated on Mean blood pressure after 15 min sitting (p=<.01). Awareness of hypertension increased mean blood pressure by 11.5 mm Hg after 15 minutes sitting (P<0.01) and significantly increased heart rate and epinephrine responses to a cold pressor test.
