[Left ventricular hypertrophy of the hypertensive patient: relation to exertional and ambulatory blood pressure].
In a prospective study the relation of left ventricular hypertrophy and exercise versus ambulatory blood pressure was analysed in 31 patients with essential hypertension (10 females, 21 males, mean age 44 +/- 14). Hypertension is borderline and has never been treated in 8 patients, mild to moderate in 24 patients who had discontinued therapy at least 8 days prior to the study. M mode echocardiogram, bicycle exercise testing and ambulatory blood pressure monitoring (spacelabs 5200) were performed within a 7 days period. Left ventricular wass (LVM) was calculated from M. mode echo data according to Devereux's formula and used to determine a LVM index (LVM/Body surface area). Correlations between LVM index and rest (R) SBP, end exercise (EE) SBP, the average of approximatively 60 SBP recordings from 7H to 22H (A-SBP) and the average of the 5 highest (5H) SBP recordings in the day are reported: (Formula: see text). There is no significative correlation with diastolic blood pressure.


CONCLUSIONS
24H A-SBP and EE-SBP appears to correlate better with severity of LVH than does the R-SBP. The selection of the 5 highest SBP in a day do not improve the correlation compared with R-SBP.
