HIGH BLOOD PRESSURE IN HEMODIALYSIS: PREVALENCE AND PROGRESSION

Abstract

Objective: High blood pressure (hypertension) is frequently found in chronic hemodialysis patients. It affects the prognosis by increasing the morbidity and mortality of patients. The objective of our study was to assess the prevalence of hypertension and to study its evolutionary profile in chronic hemodialysis patients at the University Hospital of Béjaia Design and method: This is a three-year retrospective cross-sectional study of 40 patients who have been chronic hemodialysis patients for at least one year and are over 18 years of age. For each patient, we recorded age, sex, initial nephropathy, date of start of hemodialysis, blood pressure balance, fluid status and different treatments prescribed. Results: We included 40 haemodialysis patients: 24 men and 16 women. The average age of our population was 54.37± 15.33 years. The duration of hemodialysis was 08.17± 7.5 years. High blood pressure was found in 67.5%. All of our patients were on antihypertensive therapy at the start of dialysis. After 3 years of evolution, 55% of patients had reached the blood pressure target, 30% had a correct blood pressure without any therapy and 15% had not reached the blood pressure targets despite triple therapy. Blood pressure balance in dialysis patients; Of course, it depends on adherence to treatment and hygienic and dietary rules, but also on effective dialysis and strict control of fluid balance in order to fight against volo-dependent hypertension. Conclusions: The control of hypertension in dialysis patients is essential and must include, in addition to adherence to treatment and dietary rules, adequate dialysis and strict control of dry weight, which must be assessed and adjusted periodically.
