本研究探讨疼痛敏感性及其与动脉血压的关系，在贪食症神经性（BN）。MethodsFourteen妇女谁符合诊断和统计手册的精神疾病，第4版，标准BN，清除亚型，和14个对照组进行了测试，缺血性疼痛敏感性后，延长基线期。血压，心输出量，每搏输出量，总外周阻力进行了评估，在基线期间，缺血性疼痛测试，并在自愿tolerance.ResultsBN妇女有显着更大的缺血性疼痛耐受性比对照组。此外，只有BN女性的血压与疼痛敏感性相关。在疼痛的过程中，并在点的耐受性symptoms血压呈正相关的疼痛阈值和耐受时间和负相关的额定不愉快的疼痛BN，而没有关系，涉及血压和疼痛的敏感性被观察到在controls.ConclusionsThese结果可能有影响适应不良的变化，中枢疼痛心血管调节系统的妇女BN。
ObjectiveThis study examined pain sensitivity and its relationship to arterial blood pressure in bulimia nervosa (BN).MethodsFourteen women who met Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, criteria for BN, purging subtype, and 14 controls were tested for ischemic pain sensitivity after an extended baseline period. Blood pressure, cardiac output, stroke volume, and total peripheral resistance were assessed during baseline, during ischemic pain testing, and at the point of voluntary tolerance.ResultsWomen with BN had significantly greater ischemic pain tolerance than controls. Additionally, only for BN women was blood pressure related to pain sensitivity. Systolic blood pressure during the pain procedure and at the point of tolerance was positively related to pain threshold and tolerance times and negatively related to rated unpleasantness of pain in BN, whereas no relationships involving blood pressure and pain sensitivity were observed in controls.ConclusionsThese results may have implications for maladaptive changes in central pain-cardiovascular regulatory systems for women with BN.
