Abstract     The influence of daily activities and emotional stress on ambulatory blood pressure (ABP) monitoring in two groups of patients is described. Sixty-seven consecutive patients were divided into two groups according to their conventional blood pressure (BP) levels: the hypentensive group and white coat hypertension group. Both groups were not perviously treated with antihypertensive drugs. All patients underwnt 24-h ABP monitoring and marked their activity and mood at the time of measurement in a diary. The Spacelabs 90202 ABP oscillometric monitors (Spacelabs, Inc.) were used. In the hypertensive group, 66% of patients were hypertensive (24 h average 144 +- 22/88 +- Hg), while in the white coat hypertension group 25% of ABP monitorings were hypertensive (128 +- 17/80 +- mm Hg). Diary data were analyzed with the multipleregression anaysis to evaluate the quantitativ effects data were analyzedwith the multiple regression analysis ot evaluate the quantitative effects of activities and mood on the variability of BP. THe standardized BP values of each patient were used. Statistical analysis accounted for 37.8 and 32.4% of variability for the systolic BP in the hypertensive and white coat hypertension group and for 38.6 and 33.8% of diastolic BP, respectively. Only a minor part of BP variability was explained with regular cyclic functions (the circadian rhythm). Typically 8 to 9 independent covariates entered the stepwise multiple regression analysis. The most important covariates of BP in both groups were body position and locationof patient ("at job," "outside"). Diferent activities and mood of thepatient influence ABP. It is important to consider various levels of activity and emotional stress in the evaluation of ABP monitoring.
