PARP1 and coronary artery disorder: In CAD patients, along with the increasing levels of 8-OHdG, vessels scores (P = 0.024, Figure 3D) and modified Gensini scores (r = 0.228, P = 0.012, Figure 3E) were gradually increased; there was a positive correlation between PARP activities and modified Gensini scores (r = 0.234, P = 0.010, Figure 3F).
