Figure 4 Bar Graphs Illustrating the Frequency and Distribution of Ruptures and Erosions in the Major Coronary Arteries Relative to the Degree of Thrombus Maturation
Frequency and distribution of (A) ruptures and (B) erosions in the major coronary arteries relative to the degree of thrombus maturation. The proximal regions consisted of the first 3 cm for the right coronary artery (pRC), before the first diagonal branch for the left anterior descending artery (pLAD), and the obtuse marginal for the left circumflex artery (pLCx). The mid-segments were between the first and second diagonals for the LAD, between left obtuse marginal (LOM) 1 and LOM 2 for the LCx, and beyond 3 cm of the right coronary artery (RCA) to the right marginal branch. The solid bars represent culprit plaques with early stage thrombi (<1 day of age), whereas the unfilled (open bars) represent culprit lesions with late-stage thrombi characterized as lytic (1 to 3 days), infiltrating (4 to 7 days), or healing (>7 days of age). Note the majority of ruptures and erosions were localized to the proximal LAD or RCA where there were far greater numbers of plaque erosions with late thrombi. dLAD = distal left anterior descending coronary artery; dLCx = distal left circumflex coronary artery; dRC = distal right coronary artery; LM = left main.
