[Predictive criteria of left ventricular hypertrophy given by ambulatory monitoring of blood pressure in hypertension of the elderly].
Eighty-nine patients over 65 years of age, with mild to moderate hypertension, underwent ambulatory blood pressure monitoring during 1988 and 45 of them also underwent echocardiography. Concentric left ventricular hypertrophy was diagnosed in 9 patients (20%) and criteria predictive of this complication were looked for in the results of the ambulatory pressure monitoring. The most predictive factors seemed to be: nocturnal systolic blood pressure (the average of the systolic values recorded between 22 h and 6 h); the percentage of excessive nocturnal values (values over 120/80 during the same nocturnal period); the loss of diurnal rythm with absence of the clearcut difference between the daytime and nocturnal blood pressure value; increased differential pressure, a sign of reduced arterial compliance. These notions, based on ambulatory blood pressure recordings, have diagnostic and prognostic implications (need for echocardiography) and important therapeutic consequences (drugs reducing LHV and improving arterial compliance).
