[The relationship between the 24 hour arterial pressure profile with heart changes in patients with essential hypertension].

A 24-h profile of arterial pressure (AP), structural-geometrical changes of the left ventricle (LV) and severity of hypertensive heart were compared in 47 patients with essential hypertension. Absolute AP and LV geometric models were not related. In patients with concentric LV hypertrophy, the time index (TI) of night systolic hypertension was significantly higher than TI in excentric LV hypertrophy. A relationship was found between mean day systolic pressure, a morning rise in AP and form of LV hypertrophy. The severity of hypertensive heart correlated with TI of 24-h systolic arterial pressure (SAP), TI of 24-h diastolic arterial pressure (DAP), mean 24-h SAP, mean daytime SAP, mean night SAP, mean 24-h DAP, mean daytime DAP, a morning rise in DAP. Thus, a 24-h AP profile, a morning rise in DAP, 24-h hypertension time correlate with LV structural-geometric changes and severity of hypertensive heart.
