高血压前期红外热成像图像特征分析

目的：初步阐明高血压前期红外热成像特征，为高血压前期早期诊疗提供可视化依据。方法随机选取岳阳市中医院治未病中心2015年3-6月体检的150例受检者，分为高血压前期组、高血压病组及健康志愿者组共3组，每组50例，采集各组研究对象头面部、心前区、背部红外热成像图像，并进行定性与定量分析。结果高血压前期受检者头面部可见深红色图像，心前区见红黄夹杂图像；高血压组头面部可见深红色与白色夹杂图像，心前区可见红色不连续图像；高血压前期与高血压病组背部出现背带裤样偏红图像。定量研究结果显示，高血压前期受检者头面部平均温度显著低于高血压病组（P=0.004），高于健康志愿者组（P=0.017）；心前区平均温度显著低于高血压病组（P＜0.001），高于健康志愿者组（P=0.010）。结论高血压前期人群在头面部、心前区以及背部有其特定的红外热图，为高血压前期的早期诊疗提供可视化依据。

Analysis of the Characteristics of Infrared Imaging in Pre-Hypertension Patients

Objective To clarify the characteristics of infrared thermal imaging in pre-hypertension, and provide the basis for early diagnosis and treatment of hypertension. Methods 150 cases of patients selected from Preventive Treatment of Disease Center of Yueyang Hospital of TCM in March -June 2015, who were randomly divided into 3 groups:pre-hypertension group, hypertension group and healthy volunteers group 50 cases in each group. The infrared thermal images in face, precordial and back regions of all groups were given the qualitative and quantitative analysis. Results Deep red image in the head and face and red-yellow mixed image in precordial region of the pre-hypertension group was observed. In the hypertension group, deep red-white image in head and face was visible, while discontinuous red visible in precardial region. The back of pre-hypertension group and pre-hypertension group appears suspender trousers like slight red image. The quantitative results showed that the average temperature of the head and face in pre-hypertension group was significantly lower than that in the hypertension group (P=0.004), while higher than that of the healthy volunteers group (P=0.017). The average temperature in precadial region of pre-hypertension group was significantly lower than that in the hypertension group (P<0.001), while higher than that in healthy volunteers group (P=0.010). Conclusion The prehypertensive patients show specific infrared thermal image in the head and face,precadial and back regions, provide visual basis for early diagnosis and treatment of hypertension in the early stage.
