BackgroundThere is evidence linking restless legs syndrome (RLS) with increased blood pressure (BP), but the mechanism of this relation remains unclear. Is the BP increased due to some features of RLS or to deterioration of sleep caused by RLS? This study compared values of nocturnal BP in patients with RLS and patients with insomnia. If increased BP in RLS is a consequence of disordered sleep, then it should be similar to increased BP in insomnia.MethodsPolysomnographic recordings of patients admitted to a sleep center with RLS or insomnia were analyzed. Demographic and clinical data, objective sleep parameters, and nocturnal BP were compared.ResultsRecordings of 35 patients with RLS and 33 patients with insomnia were analyzed. The groups did not significantly differ in terms of demographic traits or prevalence of other comorbidities. Patients with RLS had significantly higher systolic BP during the night (122.4 ± 13.8 vs 116.3 ± 13.4; p = 0.03) and during sleep (121.4 ± 13.3 vs 115.7 ± 13.3; p = 0.04). The only significant difference in sleep architecture was an increased number of periodic limb movements in sleep (PLMS) and PLMS with arousal in the RLS group (25.5 ± 24.6 vs 13.9 ± 22.7; p = 0.02 and 4.7 ± 5.4 vs 2.1 ± 3.4; p = 0.01).ConclusionOur results suggest that patients with RLS have higher nocturnal BP than patients with insomnia, and that increased PLMS is related to the increase in BP.  相似文献

BackgroundWe examined whether current overall attention deficit hyperactivity disorder (ADHD), inattention, or hyperactivity symptom severities are associated with the current presence and persistent history of sleep problems.MethodsN = 942 participants of the Netherlands Sleep Registry filled out online several validated questionnaires. Regression analyses were performed to assess the association between (1) current overall ADHD symptom severity and the current presence of sleep problems, (2) current ADHD symptom-severity groups and the persistent history of sleep problems, and (3) current inattention or hyperactivity symptom severities and the current presence of sleep problems.Results(1) Current overall ADHD symptom severity was associated with the odds of suffering from probable obstructive sleep apnea syndrome (OSAS), restless legs syndrome (RLS), periodic limb movement disorder (PLMD), insomnia disorder (ID) with predominant difficulties initiating sleep (DIS) and maintaining sleep (DMS), but not with the odds of suffering from narcolepsy or ID with predominant early-morning awakening (EMA). Current overall ADHD symptom severity was also associated with an extreme evening chronotype but not with short sleep. (2) The group with the most severe current ADHD symptoms was more likely to have a history of persistent OSAS, RLS, and ID. (3) The severity of symptoms of hyperactivity, but not of inattention, was specifically associated with probable RLS, PLMD, ID with DIS or DMS, and short sleep. Inattention symptom severity was only related to the probability of being an extreme evening chronotype.ConclusionADHD severity, especially the severity of hyperactivity, is associated with the current presence and persistent history of sleep problems.  相似文献

目的:观察桃红四物汤加减方内服联合中医外治疗法治疗动脉硬化闭塞症的临床效果。方法:将210例临床为动脉硬化闭塞症、辨证为瘀阻脉络型患者随机分为A组、B组和C组。三组在控制血压、血糖、血脂等基础治疗上,分别加用西药常规治疗(A组)、桃红四物汤加减方内服结合西药常规治疗(B组)及中西医结合综合治疗(C组)。检测血清凝血酶原时间(PT)、纤维蛋白原(FIB)、三酰甘油(TG)、总胆固醇(TC)、低密度脂蛋白(LDL-C)水平,测量并计算各组患者治疗前及治疗后踝肱指数(ABI),通过B超测量各组患者治疗前及治疗后股浅动脉、胫后动脉和足背动脉的血管内径、峰值流速和血流量。结果:疗效显著性C组B组A组(P0.05);血脂生化指标除PT及FIB治疗前后无统计学意义(P0.05)外,其余指标均有所改善,且改善效果C组优于B组,更优于A组(P0.01);三组治疗后ABI均有改善(P0.05),且改善效果C组优于B组,更优于A组(P0.01);三组治疗后B超检测项目均有改善(P0.05),其中股浅动脉的血流量、足背动脉的峰值速度和血流量的改善效果C组及B组均明显优于A组(P0.01),但C组优于B组不明显,其余检查指标三组内每两组间的治疗效果差异均有统计学意义(P0.01),改善效果C组优于B组,更优于A组。结论:桃红四物汤加减方内服联合中医外治疗法治疗脉络瘀阻型下肢动脉硬化闭塞症可明显改善患者多项血脂生化及血流物理指标,疗效明显优于单纯西医及中药内服结合西药常规治疗。  相似文献

Heparin-induced thrombocytopenia (HIT) is of special interest to vascular surgeons as heparin is the predominant anticoagulant used before, during, and after vascular surgery. Further, the prothrombotic nature of this antibody-mediated disorder leads to a high frequency of limb ischemia due to large arterial occlusion by platelet-rich (“white”) clots or because of extensive venous thrombosis involving large veins and small venules. This latter syndrome has been associated with coumarin anticoagulation of HIT-associated deep-vein thrombosis (coumarin-induced venous limb gangrene). Non-heparin anticoagulants, such as the direct thrombin inhibitors (lepirudin, argatroban), may be needed for intraoperative management of a patient with suspected acute HIT who requires vascular surgery. The transience of HIT antibodies provides a rationale for intraoperative use of heparin in a patient who has recovered from HIT and in whom HIT antibodies are no longer detectable.  相似文献
