Abstract

EVALUATION OF A SMOOTH BLOOD PRESSURE RESPONSE TO TREATMENT: Smooth or uniform blood pressure control is an obvious goal of antihypertensive therapy, but it is difficult to assess by the traditional clinic blood pressure measurements. Ambulatory blood pressure monitoring is therefore increasingly being used to evaluate new antihypertensive drugs and to assess the adequacy of treatment. The use of ambulatory blood pressure monitoring is based on two assumptions: that treatment must be continuously optimal, and that more frequent blood pressure measurements during treatment, particularly at different times and during various types of activity and mental states, may lead to a more accurate assessment than infrequent measurements in the clinic. When ambulatory blood pressure monitoring is used, the effect of a given antihypertensive agent or of a given antihypertensive regimen can be tested on the average blood pressure values over 24 h, or on day- or night-time values. The actual verification of the achievement of a uniform reduction of blood pressure throughout the 24-h time span can be achieved by comparing 24-h blood pressure profiles before treatment and during treatment. The so-called trough: peak ratio is generally used in a...Continue Reading
