Rate of Blood Pressure Control among Hypertensive Patients with Hemodialysis in Sohag University Hospital

Background and Aim: Hypertension is a common comorbidity in hemodialysis patients, complicating cardiovascular management.While hemodialysis is known to affect blood pressure, the link between dialysis and hypertension control is not well understood.Our study investigates how hemodialysis affects blood pressure control in hypertensive patients and examines the frequency of cardiovascular events in this population. Materials and Methods:This cross-sectional observational study included 57 hypertensive hemodialysis patients at Sohag University Hospital.Data collected included demographics, comorbidities, hemodialysis parameters, blood pressure (pre-dialysis, inter-dialysis, and post-dialysis), and incidence of cardiovascular events.Mean arterial pressure (MAP) was also calculated. Results:The mean age of participants was 48.3 years (15.18),with 73.68% male.The median hemodialysis duration was 36 months, and the median frequency was 3 sessions per week.A significant reduction in MAP was observed during dialysis on the first day compared to pre-dialysis (P < 0.001).Despite these improvements, 64.91% had uncontrolled hypertension, while 35.09% achieved control.Cardiovascular events were infrequent: cerebrovascular stroke (7.02%), myocardial infarction (1.75%), hypertensive urgency (14.04%), and pulmonary edema (1.75%); there were no significant differences between the controlled and uncontrolled hypertension groups. Conclusion:Hemodialysis was associated with significant short-term, procedure-related blood pressure fluctuations across pre-dialysis, intradialytic, and interdialytic time points; however, sustained blood pressure control remained suboptimal, with most patients classified as uncontrolled.These findings highlight the limitations of relying solely on in-unit blood pressure measurements and support the need for more comprehensive monitoring strategies in hypertensive patients receiving hemodialysis.
