ANALYSIS OF THE DATA OBTAINED AT AMBULATO RY 24-H MONITORING OF ARTERIAL-PRESSURE IN HYPERTENSIVE SUBJECTS

The authors have found that more accurate prognosis of left ventricula r myocardial hypertrophy (LVMH) may be made basing on fluctuations and variability of arterial pressure throughout the day: significant fluc tuations of arterial pressure at night and pronounced variability of s ystolic arterial pressure in the day time and at night are indicative of essential hypertension unstability and may contribute to LVMH progr ession. Of still greater prognostic significance is assessment of 24-h arterial pressure rhythm by the degree of a night fall (DNF) in diast olic arterial pressure (DAP). A disturbed 24-h rhythm of arterial pres sure (a fall in DNF of DAP) is a predictor of LVMH development.
