To summarize the current evidence regarding epidemiology, clinical pathophysiology, and latest therapeutic approaches for the management of intradialytic hypertension (IDH).IDH is a rather common complication of dialysis, affecting 10-15% of the patient population and significantly increasing the cardiovascular risk. Its pathophysiology involves multiple mechanisms, including volume and sodium overload, sympathetic nervous system (SNS) and renin-angiotensin-aldosterone system (RAAS) overactivity, endothelial dysfunction, and arterial stiffness. IDH management requires a combination of nonpharmacological and pharmacological interventions. The first mainly focus on volume control through dry weight optimization and modification of dialysate sodium, as studies show that strict volume control or low dialysate sodium can significantly reduce intradialytic and ambulatory blood pressure (BP). Pharmacological interventions have also been examined in research studies. Beta-blockers, particularly those with vasodilatory properties, can effectively target mechanisms such as SNS overactivity and endothelial dysfunction, and have shown some promising results reducing both intradialytic and ambulatory BP. Other drugs classes have also been explored as potential therapeutic options for IDH management, though further research is needed to clarify the efficacy of these interventions. A tailored approach addressing both the underlying pathophysiological mechanisms and individualized patient is warranted for improving BP control and cardiovascular outcomes in this high-risk population.
