Blood levels of NETs at day-1 was significantly lower in patients with vs. without a right ventricular dilation (40 [33.5, 105.6] vs. 63 [37.7, 88.6] p < 0.001, 0 [0, 0.3] vs. 3 [0.4, 4.9] p = 0.622, and 2.7 [0.8, 12.5] vs. 6.1 [2.6, 18.4] p < 0.001 for MPO+, Cit-H3+, and MPO+ Cit-H3+ NETs, respectively). The gene discussed is MPO; the disease is Right ventricular dilatation.
