abstract

  • To examine the adequacy of hypertension control, we monitored the blood pressure (BP) of 53 hemodialysis patients who received treatment for hypertension. BP measurement using an ambulatory BP monitor began 1 hour before dialysis and continued every 30 to 60 minutes for 48 hours until the next dialysis. Diet, medications including antihypertensive drugs, and hemodialysis prescription were not changed during this study. Each patient had a mean of 68 BP measurements during the monitoring period. Mean (+/- SD) systolic and diastolic BP levels of all patients over 48 hours were 158.6 +/- 22.7 mm Hg and 88.7 +/- 16.6 mm Hg, respectively, without diurnal variations. In these, BP loads (the percentage of systolic BP exceeding 150 mm Hg and diastolic BP exceeding 90 mm Hg) were 58.4% and 39.4%, respectively, suggesting that hypertension was inadequately controlled for more than half of the study period. Eight patients (15%) maintained BP within normal ranges at all times. All patients lost weight (2.9 +/- 0.9 kg) at the end of dialysis by ultrafiltration. However, only 27 patients (51%) had a greater than 5% decrease in mean arterial BP post-dialysis, which returned to predialysis levels within 12 to 24 hours. Reduction of BP postdialysis was significantly more common among black patients (72%) than white patients (30%) (P less than 0.01). However, there was no difference in age, cause of kidney disease, amount of ultrafiltration, and BP loads between those whose BP decreased and those whose did not. BP monitoring was repeated in eight patients, 2 to 3 months after adjustment of their antihypertensive regimens.(ABSTRACT TRUNCATED AT 250 WORDS)
