P-88: Correlation of a novel research cardiovascular profiling system with ambulatory blood pressure monitoring

Introduction: The elasticity of the vessels affects the shape of the blood pressure waveform. Not many studies analyze a relation between such evaluation and Ambulatory Blood Pressure Monitoring (ABPM). AIMS: 1. To determine the prevalence of abnormal large and/or small artery elasticity index (AEI). 2. To determine its correlation with ABPM. Methods: N=69, aged 31–81 (60,49+-1,63), M/F ratio= 39/30, 40 hypertensive.Large (C1) and small (C2), AEI, systemic vascular resistance, total vascular impedance. HDI/PulseWave CR-2000. ABPM : Activity, rest and critical (06:00–9:00am) periods: average systolic BP (aSBP), average diastolic BP (aDBP), average Mean Arterial Pressure –MAP-, Ambulatory pulse pressure (APP). Systolic and diastolic BP burden (systolic>125 and diastolic>75 mmHg pressure reading percentages) (SBPB and DBPB). Hemodynamic load (HL=Heart Rate x MAP/100). SBP variability (SBPV) and DBP variability (DBPV). HR variability (HRV). Statistical: t-Student, Levene’s, Mann-Whitney U test. Results: 1- The prevalence of abnormal C1 was 36,2% (N=25). We found differences in age (p
