In patients with end-stage renal disease (ESRD) treated with haemodialysis or peritoneal dialysis, hypertension is common and often poorly controlled. Blood pressure (BP) recordings obtained before or after haemodialysis display a J- or U-shaped association with cardiovascular events and survival, but this most likely reflects the low accuracy of these measurements and the peculiar haemodynamic setting related to dialysis treatment. Elevated BP detected by home or ambulatory BP monitoring is clearly associated with shorter survival. Sodium and volume excess is the prominent mechanism of hypertension in dialysis patients, but other pathways, such as arterial stiffness, activation of the renin-angiotensin-aldosterone and sympathetic nervous systems, endothelial dysfunction, sleep apnoea and the use of erythropoietin-stimulating agents may also be involved. Non-pharmacologic interventions targeting sodium and volume excess are fundamental for hypertension control in this population. If BP remains elevated after appropriate treatment of sodium and volume excess, the use of antihypertensive agents is necessary. Drug treatment in the dialysis population should take into consideration the patient's comorbidities and specific characteristics of each agent, such as dialysability. This document is an overview of the diagnosis, epidemiology, pathogenesis and treatment of hypertension in patients on dialysis, aiming to offer the renal physician practical recommendations based on current knowledge and expert opinion and to highlight areas for future research.
在接受血液透析或腹膜透析治疗的终末期肾病(ESRD)患者中,高血压很常见,且通常难以控制。在血液透析前后获得的血压(BP)记录与心血管事件和生存呈 J 形或 U 形关联,但这很可能反映了这些测量的低准确性以及与透析治疗相关的特殊血液动力学环境。家庭或动态血压监测检测到的血压升高与生存时间缩短明显相关。钠和容量过多是透析患者高血压的突出机制,但其他途径,如动脉僵硬、肾素-血管紧张素-醛固酮和交感神经系统的激活、内皮功能障碍、睡眠呼吸暂停和促红细胞生成素刺激剂的使用,也可能参与其中。针对钠和容量过多的非药物干预措施是该人群控制高血压的基础。如果在适当治疗钠和容量过多后血压仍然升高,则需要使用降压药物。透析人群中的药物治疗应考虑患者的合并症和每种药物的特定特征,如可透析性。本文概述了透析患者高血压的诊断、流行病学、发病机制和治疗,旨在根据现有知识和专家意见为肾脏医生提供实用建议,并强调未来研究的领域。
