FIGURE 2.
Coronary plaque progression detected by consecutive coronary CTA in the 61-year-old male cocaine user. The participant underwent contrast-enhanced coronary CTA on March 27, 2014 (baseline), and October 2, 2014 (6-month follow-up). In the left image from baseline CTA, calcified plaque in the proximal left anterior descending coronary artery (LAD) near the first diagonal is eccentric and no any narrowing is seen. In the right image from 6-month follow-up, plaque is seen in the proximal LAD near the first diagonal, causing at least 50% diameter stenosis. During the 6-month study, he used cocaine for 70 days. CTA indicates CT angiography.
