Systolic blood pressure and pulse pressure: role of 24-h mean values and variability in the determination of organ damage.
An increasing amount of data suggests that systolic blood pressure (SBP) and pulse pressure (PP) may more closely relate to and thus favour the atherogenic process than does diastolic blood pressure (DBP). The baseline data from the ongoing European Lacidipine Study on Atherosclerosis (ELSA) recently indicated that carotid artery atherosclerosis in normocholesterolaemic patients with mild or moderate essential hypertension is more closely related to SBP and more so PP than to DBP and lipid variables. Other new data point to the effects of hypertension on arterial compliance, as well as the effects of 24-h blood pressure variability on arterial compliance and distensibility. When viewed in their entirety, these data present a compelling case for the closer monitoring of SBP and PP with respect to arterial compliance, and the need for aggressive blood pressure treatment to control and perhaps reverse the underlying pathological changes in arterial structure and function in hypertensive patients.
