Abstract

Methods: Before and three months after KTx, we obtained radial pressure waveforms using applanation tonometry, in a group of 61 patients with restored renal function (eGFR > 45 ml/min/1,73 m2). Radial waveforms were recorded over a 10 seconds period and ensemble-averaged (using in house-MATLAB program) to obtain a single waveform and then modelled using two Gaussian functions, was then determined as the transit time between the first systolic peak T1 and the early diastolic peak T2.

P.66肾移植后桡动脉收缩期-舒张期脉搏传递时间

方法：在肾功能恢复（eGFR>45ml/min/1.73m2）的61例患者中，在KTx术前和术后3个月，我们使用压平眼压计获得了径向压力波形。在10秒内记录径向波形，并进行整体平均（使用内部MATLAB程序）以获得单个波形，然后使用两个高斯函数建模，然后确定为第一个收缩峰值T1和早期舒张峰值T2之间的过渡时间。
