目的探讨激光散斑血流图(LSFG)显示的视神经头搏动血流形态参数与超声心动图测定的左心室舒张末压力及质量之间的关系。我们对175例接受多导睡眠监测的受试者进行横断面分析。采用标准M型二维彩色多普勒超声评价E/e比值(代表LV舒张末压力)和LV质量。评价了井喷分值和加速时间指数等脉动流态分析参数。分别对组织、血管和整个视神经头的参数进行分析。我们进行了一次回归分析和多元回归分析，以确定搏动性血流形态是否是E/E比值和LV质量的独立因素。影响E/E比值的独立因素是井喷时间-组织(标准回归=-0.27，t值=-2.90，p
To evaluate the relationships between parameters of the pulsatile flow form in the optic nerve head shown by laser speckle flowgraphy (LSFG) and the left ventricular (LV) end-diastolic pressure and mass obtained by echocardiography. We cross sectional analyzed the cases of 175 subjects who had undergone polysomnography. Standard M-mode two-dimensional color Doppler imaging was performed to evaluate the E/e ratio (which represents the LV end-diastolic pressure) and LV mass. The pulsatile flow form analysis parameters of the blowout score and acceleration time index were evaluated. The parameters were analyzed separately for the tissue, vessels and throughout the optic nerve head (All). We performed a single regression analysis and a multiple regression analysis to determine whether pulsatile flow form are independent factors for the E/e ratio and LV mass. The factors contributing independently to the E/e ratio were blowout time-Tissue (standard regression=-0.27, t-value=-2.90, p
