title: [Arterial hypertension in patients on long-term haemodialysis].
abstract: Arterial hypertension is one of the most frequent causes of chronic kidney failure but also one of most frequent complications in patients on long-term haemodialysis. The aim of this work is to investigate the prevalence of arterial hypertension in long-term haemodialysis patients, and methods for treating it. A total of 168 patients (86 women and 82 men average age 62.9 +/- 12.9 years) from three dialysis centers were included in this study. Arterial hypertension was defined as blood pressure immediately before hemodialysis > 140/90 mmHg or less if the patient has been on anti-hypertensive therapy. Before the beginning of a long-term hemodialysis program arterial hypertension was registered in 139 (81%) patients. The patients were on haemodialysis 52.5 +/- 45.17 months. All patients were dialyzed three times per week, an average of 11.7 hours per week (9 to 13.5 hours). Body weight of the patients was 68.4 +/- 15.8 kg, and weight gain between dialysis treatments was 2.9 +/- 1.1 kg. Arterial hypertension was recorded in 141 patients (84%), i.e. average blood pressure before haemodialysis in all patients was 157.3 +/- 17.3/85.2 +/- 8 mmHg. The average blood pressure of the remaining patients was 132.6 +/- 8.2/ 78.3 +/- 10.3 mmHg. The patients were treated with a variety of anti-hypertensive drugs. Thirty-seven patients were on monotherapy, while the others were on combined treatment (2-4 antihypertensive drugs). The most frequently used antihypertensive drugs were calcium channel blockers (95 patients, or 67%), ACE inhibitors (47 patients, or 33%), beta-blockers (29 patients, or 20%), angiotensin II receptor blockers and alpha-blockers (25 patients, or 17%), diuretics (11 patients, or seven percent), and nine patients (6%) received central agents or drugs wich acted like an alpha+beta blocker. Prevention and treatment of arterial hypertension is a special problem for haemodialysis patients. Unfortunately, there are still no guidelines for the optimal method of measuring blood pressure in these patients, or optimal values of arterial blood pressure, the first drug of choice or optimal combination of therapies. Perhaps because of this cardiovascular morbidity and mortality among these patients is high.
