Moreover, indexes of cardiac autonomic modulation were associated with hormonal, inflammatory and oxidative stress markers: RMSSD was positively correlated with adiponectin (r = 0.86) and was negatively correlated with spleen levels of PAI-1 (r = −0.81) and cardiac levels of angiotensin II (r = −0.68); VAR PI was inversely correlated with cardiac levels of angiotensin II (r = −0.72); %LF was inversely correlated with cardiac levels of angiotensin 1–7 (r = −0.68); and %HF was positively correlated with cardiac levels of angiotensin 1–7 (r = 0.68) (Figure 5). The gene discussed is ADIPOQ; the disease is hydrops fetalis.
