- W4311760064 abstract "Abstract Introduction Hemodynamic interaction between left ventricular (LV) and arterial system is a key determinant of cardiovascular performance. The non-invasive carotid-femoral Pulse Wave Velocity (PWV), obtained with applanation tonometry, is considered the most precise way of estimating arterial stiffness. The LV myocardial work (MW), based on non-invasive LV pressure-strain loop (PSL), is a new promising tool to assess LV function. Aims The aim of the study was to evaluate the correlation between PWV and MW parameters in a population of non-hypertensive and newly diagnosed untreated hypertensive people. Materials and methods 80 people (M=48), divided in hypertensive (group 1 n=40, 45±10 years) and non-hypertensive (group 2 n=40, 40±12 years), were prospectively enrolled. All underwent conventional transthoracic echocardiogram and at the same day carotid femoral PWV was calculated with applanation tonometry (SphygmoCor® XCEL). MW parameters were obtained using 2D Speckle-tracking technique. Results Comparing the two groups, PWV and Global Work Wasted (GWW) were significantly higher in the hypertensives group (9,73±2,4 vs 7,79±1,1; p=0,001 and 146±50 vs 85±27, p=0,001), as shown in Figure 1, whereas Global Work Efficiency (GWE) and Global Work Constructive (GWC) were significantly lower (93,6±2,5 vs 95,6±1,2, p=0,001 and 2410±122 vs 2167±65, p=0,002). We found a linear and positive correlation of PWV with GWW (r=0,271, p=0,016), as seen in Figure 2, and a linear and negative correlation of PWV with GWE (r=-0,282, p=0,012). Conclusion This study highlights the role of PWV and MW evaluation in hypertensives. Higher PWV and GWW could be considered as red flags of myocardial damage suggesting the need of an early appropriate antihypertensive therapy." @default.
