Graded exercise blood pressure correlated strongly with 24-hour ambulatory blood pressure, suggesting it may be a better indicator of elevated blood pressure than clinic blood pressure.

Does graded exercise testing correlate better with ambulatory blood pressure than clinic blood pressure in patients with suspected hypertension?
Graded exercise testing provides blood pressure measurements that correlate more strongly with 24-hour ambulatory blood pressure than standard clinic measurements in patients with suspected hypertension.
Twenty-five patients with suspected hypertension were studied using the "Oxford" continuous intra-arterial blood pressure recording technique. Each patient carried out graded exercise on a bicycle ergometer, using a standard protocol, and then underwent a fully ambulatory 24-h outpatient blood pressure recording. Using computer analysis, ambulatory blood pressure in each patient was characterised by measuring the mean daytime systolic and diastolic pressures. Exercise was found to be associated with a characteristic increase in systolic and diastolic blood pressure. Submaximal and maximal exercise blood pressures were shown to correlate strongly with ambulatory blood pressure. A much weaker correlation was found between clinic and ambulatory blood pressure. These findings suggest that the blood pressure response to exercise may be a better indicator of elevated blood pressure than a causal clinic blood pressure in individual borderline subjects.
Millar-Craig et al. (Fri,) conducted a observational in Suspected hypertension (n=25). Graded exercise testing vs. Clinic blood pressure was evaluated on Correlation between exercise blood pressure and ambulatory blood pressure. Graded exercise blood pressure correlated strongly with 24-hour ambulatory blood pressure, suggesting it may be a better indicator of elevated blood pressure than clinic blood pressure.
