Ambulant 24 h blood pressure was recorded in 97 untreated hypertensive subjects (50 with, 47 without echocardiographic signs of left ventricular hypertrophy) and 45 matched normotensive subjects. Forearm vascular resistance was calculated from mean blood pressure and blood flow, which was measured by venous plethysmography during reactive hyperemia. Blood pressure variability was calculated by standard deviations of pressure values.

Left ventricular (LV) hypertrophy was assessed before and after 24 weeks of therapy with either the converting enzyme inhibitor perindopril or the calcium antagonist nifedipine. The design was a double-blind parallel study with a placebo run-in period.

Forearm vascular resistance was calculated from mean blood pressure and postischemic blood flow, which was measured by venous plethysmography. Systolic ambulant 24-h blood pressure exhibited the closest correlation with left-ventricular mass index in hypertensives (r = 0.

The risk is further increased by left ventricular hypertrophy as an independent contributor to these cardiovascular events. However, the incidence of coronary mortality and sudden death could not be reduced by antihypertensive drug therapy.
View Article and Find Full Text PDFA study of normotensive volunteers and patients with primary hypertension demonstrated the superiority of a single 24-h mean systolic and diastolic ambulatory blood pressure monitoring (SpaceLabs 90207 ABPM) over standardized sphygmomanometric casual readings. In contrast to the casual blood pressure measurement there was a significant correlation between both 24-h mean systolic and diastolic blood pressures and left ventricular hypertrophy as assessed by two-dimensional M-mode echocardiography. Although no significant differences between daytime and night-time blood pressure were demonstrated in normotensive or hypertensive subjects with or without target organ damage, larger prospective trials are required to confirm this finding.
