THERMOGRAPHIC FEATURES OF FUNCTIONAL COLD TEST IN SCHOOLCHILDREN WITH ARTERIAL HYPERTENSION

Introduction. Hypertension is in the focus of pediatricians worldwide, as it one most common diseases modern pediatric cardiology. Methods. 61 school-age children were examined. They divided into three groups: 1st group included with hypertension, 2nd – prehypertension, and control consisted normal blood pressure. Infrared thermography was performed on back surface hands, remotely, using a certified thermal imager professional software. Thermographic evaluation hands after cold test immediately end test, 1 2 minutes, final degree recovery heat radiation determined 15 minutes. The study found that decrease temperature probably higher than from group. Children prehypertension also had slightly greater compared obtained significant difference between indicators hypertension may be due to worse compensatory mechanisms microcirculatory tract, lower capillary density, presence local spasm venules arterioles them. In addition, have increased vascular resistance, which affects level fall temperature, because emission direct reflection microcirculation fingers child. Conclusion. are likely maximum slower contrast group, disorders.
