高血压、糖尿病患者光电容积脉搏波特征分析

Analysis on Characteristics of Photoplethysmography in Hypertension and Diabetes Patients

为探讨高血压、糖尿病患者PPG及其导数特征的变化情况,选取吉大二院患者和校内师生共350例,分为正常组、高血压组、糖尿病组及高血压合并糖尿病组,收集基础资料和PPG信号,采用CEEMD-DWT方法对信号去噪,提取SI、RI、CTR、W、K和B A等进行相关性分析。与正常组相比,三组SI、W、CTR差异具有统计学意义;高血压组RI、B A差异具有统计学意义,糖尿病组的K值差异具有统计学意义。结果表明PPG特征参数与高血压、糖尿病之间存在较强相关性,能反映二者动脉弹性功能的改变,可以为高血压、糖尿病血管并发症的早期发现提供依据,减缓转换为心脑血管疾病的进程。

To investigate the change in photoplethysmography(PPG) and its derivative waveform characteristics of hypertension and diabetes,350 patients,teachers and students in the second hospital of Jilin University and our university were divided into normal group,hypertension group,diabetes group and hypertension with diabetes group. The SI,RI,CTR,W,K and B/A were recorded by the PPG which was denoised using CEEMD-DWT and analyzed by correlation analysis.There was a significant difference in SI,W and CTR between three groups normal group. There was a significant difference in RI,B A between hypertension group and normal group. There was a significant difference in K between diabetes group and normal group. The result showed that PPG characteristic parameters were strongly correlated with hypertension and diabetes,which could reflect the changes in arterial elastic function;an evidence could be provided for early detection of vascular complications of hypertension and diabetes. And the conversion to cerebra-cardiovascular disease is retarded.
