P-543: Sympatho-vagal pattern correlation with cardiovascular risk scores in essential hypertension

The autonomic pattern, including analysis of heart rate variability (HRV) and baroreflex sensitivity (BRS), has been suggested by some authors as an additional factor in the evaluation of cardiovascular risk in hypertensive patients.

Description
Summary:The autonomic pattern, including analysis of heart rate variability (HRV) and baroreflex sensitivity (BRS), has been suggested by some authors as an additional factor in the evaluation of cardiovascular risk in hypertensive patients. The aim of this study is to stratify never treated mild hypertensive patients by their autonomic nervous pattern, assessed by time domain analysis of heart rate variability (HRV) and baroreflex sensitivity (BRS) and to examine if autonomic pattern correlates with some of the known cardiovascular risk factors and with the Framnigham score. We selected 290 never treated essential hypertensive patients; they underwent ambulatory blood pressure monitoring, 24hr ECG Holter (for the evaluation of HRV), non invasive continuous finger blood pressure monitoring by Portapres device (for the evaluation of BRS) and ecocardiocolordoppler; HRV variables are strongly correlated to BRS values (p
