P168 CHARACTERIZATION OF THE HEMODYNAMIC PATTERN OF CONTROLLED HYPERTENSIVE PATIENTS

Background: Hemodynamic alterations have been described in hypertensive disease. However, we still do not know if the identification of an altered hemodynamic pattern in patients with controlled hypertension could predict cardiovascular risk or evolution of hypertension. Objective: to identify the hemodynamic pattern of hypertensive patients with BP values in goals. Methods: Controlled hypertensive subjects were recruited (n = 107) and included a control group of normotensive subjects (n: 35.9). A non-invasive hemodynamic study (Z Logic, lying down / standing) was performed, and the cardiac index (CI) and vascular resistance index (VRI) data were recorded for the determination of the hemodynamic pattern. Hypodynamic pattern was considered: CI <2.5 L / min / m2 and VRI> 2500 dynas.seg.cm-5.m2; Hyperdynamic pattern IC> 4,4 L / min / m2 and VRI <2500 dynas.seg.cm-5.m2 Results: The SBP / DBP of the HTA group was 133.09 +/- 6.01 / 82.4 +/-7.2 mm Hg; and of the NT group was SBP/ DBP 123.6 +/- 9.7 / 75.5 +/- 8.9. The CI and VRI of the HTA group obtained was 2.81 l / m2 / min and 2842.31 dynas that, without corresponding to a hypodynamic pattern, showed a predominance of the VRI increase. In the control group of NT subjects, the values were 3.23 and 2289.23, respectively, corresponding to a normal pattern. The values obtained were different between both groups (p <.05). Conclusions: Controlled hypertensive patients with hypertension goals have a hemodynamics pattern with an increase in the VRI different from that of normotensive subjects. These results coincide with those reported by Ferrario and col. The relevance of the imbalance found could only be analyzed in the context of long-term follow-up to identify whether it is a predictor of CV events and / or complications.
