Key result
Chronic hypotension was associated with markedly reduced heat pain threshold and tolerance, and increased sensory and affective pain experience compared to normotension.
Why the study?
Does chronic hypotension increase sensitivity to heat pain compared to normotension?
Population
80 subjects, comprising 40 with chronic hypotension and 40 normotensive controls.
Comparison
Chronic hypotension vs Normotension
Design
Case-control

Should not yet change pain assessment in hypotensive patients; leaves open inverse BP-pain relationship for prospective trials.
Observational (n=80)
Does chronic hypotension increase sensitivity to heat pain compared to normotension?
Chronic hypotension is associated with increased sensitivity to heat pain, suggesting an inverse relationship between blood pressure and pain sensitivity across the blood pressure spectrum.
Duschek et al. (2008) conducted an observational in Chronic hypotension (n=80). Chronic hypotension vs. Normotensive controls was evaluated on Sensitivity to heat pain (pain threshold and tolerance). Chronic hypotension was associated with markedly reduced heat pain threshold and tolerance, and increased sensory and affective pain experience compared to normotension.
