Key result
Elevated blood pressure is associated with a higher pain threshold in acute pain but may reduce pain thresholds and worsen prognosis in patients with chronic pain syndromes.
Why the study?
Does elevated blood pressure affect the pain threshold in patients with acute and chronic pain syndromes?
Does elevated blood pressure affect the pain threshold in patients with acute and chronic pain syndromes?
Hypertension is associated with hypoalgesia in acute pain but may paradoxically lower pain thresholds in chronic pain syndromes.
May inform acute pain assessment in hypertensives; leaves open causal effects and interventions in chronic pain.
The paper considers the relationship between pain threshold and blood pressure (BP) in acute and chronic pain syndrome. Both experimental and clinical studies have established that elevated BP is accompanied by a higher pain threshold in acute pain (hypertension-related hypoalgesia). Epidemiological findings have shown that the prevalence of different pain syndromes is significantly lower in hypertensive patients than in individuals without hypertension. At the same time, there is evidence that elevated BP can, on the contrary, reduce pain thresholds and make prognosis worse in patients with chronic pain syndromes.

Grinyuk et al. (2016) conducted a review in Hypertension and pain syndrome. Elevated blood pressure vs. Individuals without hypertension was evaluated on Pain threshold. Elevated blood pressure is associated with a higher pain threshold in acute pain but may reduce pain thresholds and worsen prognosis in patients with chronic pain syndromes.
