Casual and ambulatory blood pressure (BP) were measured in samples of adults from two separate studies. Changes in casual BP and heart rate (HR) from the first to the second days of the studies were used with casual BP levels to try to better predict ambulatory BP. Casual BP changes significantly predicted ambulatory BP levels beyond that accounted for by casual BP levels alone in many analyses. However, they accounted for a very small proportion of the variance so as to likely be of little clinical use, and the types of changes that were predictive for one sample were not predictive for the other. Both of these problems may be due to the different proportions of hypertensives and normotensives in the two samples, and might be remedied by studying the two groups separately. This study also found that casual systolic and diastolic BP and HR show a significant decline after the first three days of measurement averaging, 19 mmHg SBP, 13 mmHg DBP, and 9 heart beats per minute.
