Deskripsi
This study examines the ability of infrared thermography (IRT) to distinguish vasculopathy patients (VP) from healthy controls (HC) during post-occlusive reactive hyperemia (PORH). Three VP and three HC participated in the study. The experimental procedure included a 3-min baseline, a 5-min occlusion at 50 mmHg above the systolic pressure, and a 3-min reperfusion. During PORH, HC had a larger temperature fluctuation of the fingertips from the baseline (1.22 ± 0.97 °C) compared to VP (0.53 ± 0.57 °C). Accordingly, color Doppler ultrasound assessed differences in the arterial resistivity index between the two groups. These findings, albeit preliminary, could facilitate IRT employment during POHR.
