Case Report Pereira et al. Exertional rhabdomyolysis microvascular reactivity Arq Bras Cardiol. 2019; 113(2):294-298 Figure 1 – Effects of skin iontophoresis of acetylcholine (ACH) on cutaneous microvascular conductance (A, expressed in arbitrary perfusion units,APU, divided by mean arterial pressure, in mmHg) before military training (BEFORE) and one day after hospital discharge (AFTER). (B) Effects of forearm post-occlusive reactive hyperemia (PORH) on cutaneous microvascular conductance. (C) Functional capillary density before (BASAL) and during post-occlusive reactive hyperemia (PORH) before military training (BEFORE) and one day after hospital discharge (AFTER). (D) Percentage change in endothelial-dependent increase in capillary density after PORH before military training (BEFORE) and one day after hospital discharge (AFTER). BASAL: values before PORH; PEAK: maximum values after PORH; INCREASE: the difference between peak and basal values. 1.2 1.0 1.5 0.5 0.0 BEFORE BEFORE AFTER AFTER 1.0 0.8 0.6 0.4 0.2 0.0 0 30 60 90 Iontophoresis Current ( µ A) CUTANEOUS VASCULAR CONDUCTANCE INCREASE - ACH (APU/mmHg) CAPILLARY DENSITY (capillaries/mm 2 ) % CHANGE OF CAPILLARY DENSITY AFTER PORH CUTANEOUS VASCULAR CONDUCTANCE INCREASE - PORH (APU/mmHg) 120 150 180 4 2 –2 –4 –6 0 120 115 105 100 110 BASAL BEFORE BASAL BEFORE BASAL AFTER BASAL AFTER PEAK BEFORE PEAK AFTER INCREASE BEFORE INCREASE AFTER PORH BEFORE PORH AFTER A C B D 297
