Evluate Relationship Of Structure And Function Of Cardiac And The Carotid Artery And Femoral Artery In Essential Hypertension With Carotid Transient Wave

Objective: Assessment relationship of structure function of cardiac and elasticity changes of carotid artery and femoral artery in patients with essential hypertension.by wave intensity(WI)Methods : 150 patients with essential hypertension according to the size of the left atrial diameter(LADs), left ventricular mass index(LVMI) and relative wall thickness(RWT) were divided into left atrial structure of normal and the left ventricular configuration group 30(group A), left atrial enlargement and normal left ventricular configuration group 30(group B), left ventricular centripetal reconstruction group 30(group C), left ventricular centripetal hypertrophy group 30(group D), left ventricular concentric hypertrophy group 30 people(E group) and 30 normal control group(N group), detecting by the M- and two-dimensional ultrasound technology. measurement of left atrial systolic diameter(LADs), left ventricular end-diastolic diameter(LVDd), inter ventricular septal end-diastolic thickness(IVSTd) and left ventricular posterior wall thickness(LVPWTd), calculation of left ventricular mass index LVMI(g/m2), relative wall thickness(RWT). Teich method calculation of left ventricular ejection fraction(LVEF), the application of pulsed doppler mitral valve blood flow spectrum, early blood flow peak velocity measurement of left ventricular diastolic E, application of tissue doppler left ventricular wall mitral peak early diastolic blood flow velocity E ’, E/E ’calculation. Technology WI for carotid artery and femoral artery function parameters: W1(early shrinkage forward wave) and W2(late shrinkage and isovo lumetric diastolic forward wave), NA(midsystole negative wave), PWVβ(pulse wave conduction velocity), β(stiffness) and Ep(vascular stress- strain elasticity coefficient), AC(compliance).Results: 1. Compared LVMI, D, E group were obviously more decreasing than the N group, with statistical significance(P < 0.05), RWT comparison, C, D group than N group the obvious increasing, was statistically significant(P < 0.05), and LVEF is obvious decrease in group E and N, with statistical significance(P <0.05). Pulse doppler and tissue doppler measurement by the E/E ’, B, C, D, E group of obvious increase than the N group, with statistical significance(P < 0.05). 2. High blood pressure in each group compared with control WI parameter: A, B, C, D group,much more increased than N group, W1 was statistically significant(P < 0.05); E group and N group is a decreasing trend, with statistical significance(P < 0.05). A, B, C, D, E group compared with N group comparison, NA, PWVβ, β, Ep has the varying degree to increasing, with statistical significance(P < 0.05), W2 and AC are different degree of decline, with statistical significance(P < 0.05). 3. Hypertension WI parameter comparison between groups, compared group B and A, compared group C and B, compared group D and C, compared group E and D,, NA, PWVβ,β, Ep has the varying degree to increasing, was statistically significant(P < 0.05), W2 and AC are different degree of decreasing, with statistical significance(P < 0.05). 4. LVEF in hypertension group was positively related with W1(rC = 0.668, rF = 0.573, P < 0.01), E/E ’and negatively correlated with W2(rC =-0.585, rF =- 0.632, P < 0.01).Conclusion: 1. Evaluate artery elastic function, and the systolic and diastolic function of the heart in the patients with high blood pressure by The WI,and elastic function changing of carotid artery can reflect the heart function changing better than femoral artery. 2. The structure and function of cardiac changing closely relate to big blood vessel function in high blood pressure,...
