To evaluate a possible correlation between sympathetic activity and blood pressure in uremia, catecholamines and blood pressure were determined in 81 uremic patients. In 34 of these 81 patients, thyroid hormones were also measured. In 16 patients on maintenance dialysis, a longitudinal study was performed to compare long-term blood pressure and catecholamine variations. No correlation was found between mean blood pressure and noradrenaline in the 81 patients as a whole, but when male and female patients were evaluated separately, a significant correlation was found in the former group. In the 34 patients, a correlation between mean blood pressure and noradrenaline was found only when hypothyroid patients were excluded. Variations in mean blood pressure induced by chronic dialysis were related to noradrenaline changes in the 16 patients studied. In conclusion, sympathetic activity seems to be correlated to blood pressure in uremic patients.
