[Cardiac mass, ventricular relaxation parameters and their correlation with blood pressure during rest and ambulatory monitoring].

A resting blood pressure (Dynamap, 8AM-8PM, one recording every 15 minutes) has been recorded among 60 patients; mean age: 51 +/- 14 years (24 females, 36 males; 3 normotensive and 57 hypertensive WHO) and a echocardiogram TM and two-dimensional with doppler in order to measure the interventricular septum thickness, Left Ventricular Posterior Wall Thickness and the left Ventricular Internal diameter with which we can calculate the myocardial mass (MM, Devereux formula) and the myocardial mass index using the body surface. Furthermore ventricular relaxation has been studied (A/E, PHT) by using doppler echocardiogram. During the same week an ambulatory blood pressure (Nippon Colin 8AM-8PM one reading every 15 minutes) has been recorded. The blood variables are the mean of the recording, systolic, diastolic, mean. We have confirmed the conclusion between blood pressure and left ventricular mass by using resting and ambulatory blood pressure recordings. But it does not exist any significant difference within we compare the correlations coefficients (Hotteling's Test with Williams modification) obtained with two devices. In revenge this difference exists with ventricular relaxation index A/E to MBP: mMBPr = 0.51, mMBPa = 0.34 (p less than 0.05), and PHT to MBP: mMBPr = 0.49, mMBPa = 0.31, (p less than 0.05) and to the SBP: mSBPr = 0.54, mSBPa = 0.35, (p less than 0.05).,the relationship between blood pressure and myocardial mass and by, the heart effect from hypertension can be studied by using in any case resting and ambulatory blood pressure recordings. This will confirm the hypothesis in which the blood pressure recordings multiplication is more important than the way of recording it.(ABSTRACT TRUNCATED AT 250 WORDS)
