title: Ambulatory blood pressure and left ventricular hypertrophy.
abstract: The relation between ambulatory blood pressure and left ventricular mass has been studied with three main aims. The first aim was to validate this new technique for measuring blood pressure. Most studies have shown that the left ventricular mass is correlated more closely to the ambulatory blood pressure than it is to the office blood pressure. The second aim was to define the parameters of most interest in ambulatory recordings. Although the mean 24 h blood pressure has emerged as the parameter of most clinical interest, other parameters, such as the blood pressure measured during activity, the difference between daytime and night-time values and the blood pressure measured when the subject arises in the morning, may also be of value. The interest of these parameters awaits confirmation in prospective studies. Random peak pressures and the variability as determined by discontinuous measurements using non-invasive methods appear to be of little value. The third aim was to assess the value of ambulatory monitoring in identifying the role played by mechanical as opposed to genetic, humoural and hormonal factors in the development of left ventricular hypertrophy in the hypertensive patient. Ambulatory blood pressure monitoring might prove of particular value in assessing the true impact of blood pressure reduction by antihypertensive therapy on left ventricular hypertrophy.
