24-hour blood pressure measurement has greater prognostic power than clinic values in determining cardiovascular pathology in hypertension.
Does 24-hour ambulatory blood pressure monitoring improve prognostic assessment compared to clinic blood pressure values in patients with hypertension?
24-hour ambulatory blood pressure monitoring may provide superior prognostic information compared to isolated clinic measurements in hypertensive patients.
AbstractLong-term recordings of blood pressure in an individual could logically be expected to have greater prognostic power than values recorded in the clinic in view of the known inaccuracies and variability of the latter. This feature has been shown to be true in a large series investigated by Perloff and colleagues1. Specific components of the 24h profile may have greater prognostic power than others, 'basal' blood pressure (generally equated with night-time resting values) has been thought by some2 to have greater predictive value than that recorded during less standardised activity at other times of day. A further hypothesis is that high intrinsic blood pressure variability may play an independent role in determining cardiovascular pathology when measured either as a global index3 or as a specific component such as the slope of the early morning rise in pressure4.Key Words: Ambulatory monitoringblood pressurevariabilityhypertensionprognosisleft ventricular hypertrophymyocardial infarctionstroke
Mann et al. (1985) conducted a review in Hypertension. 24-hour blood pressure measurement vs. Clinic blood pressure values was evaluated on Prognosis / cardiovascular pathology. 24-hour blood pressure measurement has greater prognostic power than clinic values in determining cardiovascular pathology in hypertension.
