目的:对中老年糖尿病患者无创心脏血流动力学临床探索,以期为临床研究提供借鉴。方法:选取我院接治的56例中老年糖尿病患者作为本次研究对象,划分为观察组,选取同期56例正常人群作为对照组,借助LIFEGARDⅡ型无创血流动力学监护系统对两组的心输出量(CO)、心率(HR)等指标进行测定对比。结果:经统计发现,观察组与对照组在BMI和甘油三酯方面并无显著性差异(P>0.05),而观察组的腰臀比(WHR)、空腹血糖(FPG)和总胆固醇(TC)明显升高(P<0.05),差异具有统计学意义。在血流动力学参数对比中,观察组的ACI、VI指标均呈现显著性降低,且与对照组具有显著性差异(P<0.05),而SBP、PP、PEP、STR则显著性升高,与对照组差异显著(P<0.05),且具有统计学意义。结论:中老年糖尿病患者存在不同程度的心脏血流动力学异常症状,其中加速指数与速度指数可作为糖尿病心脏血流动力学异常的无创性敏感性评价指标。
Objective: To explore the noninvasive cardiac hemodynamics in middle-aged and elderly patients with diabetes, in order to provide reference for clinical research. Methods: Fifty-six middle-aged and elderly diabetic patients treated in our hospital were selected as the study group, divided into observation group, 56 normal subjects were selected as the control group, with LIFEGARD Ⅱ noninvasive hemodynamic monitoring system on the heart of both groups Output (CO), heart rate (HR) and other indicators were measured contrast. Results: The statistics showed that there was no significant difference between BMI and triglyceride in the observation group and the control group (P> 0.05), while the WHR, FPG and TC ) Was significantly higher (P <0.05), the difference was statistically significant. Compared with the control group, the ACI and VI indexes of the observation group showed a significant decrease (P <0.05), while the SBP, PP, PEP and STR of the observation group were significantly increased in the hemodynamic parameters, There was significant difference with the control group (P <0.05), and had statistical significance. CONCLUSIONS: There are varying degrees of abnormalities of cardiac hemodynamics in middle-aged and elderly diabetic patients, of which the acceleration index and speed index can be used as a noninvasive and sensitive evaluation indicator of hemodynamic abnormalities in diabetic patients.
