  1. Detailed assessment of coronary vessels from the 18 subjects included in the study are collected. Results for visibility of the coronary ostia, vessels sharpness, and vessel length are listed. Asterisks indicate statistically significant differences in vessel measurements between Group 1 (intubated patients) and Group 2 (free-breathing patients), which appears only in the visible length of RCA
  2. LAD left anterior descending coronary artery, LCX left circumflex coronary artery, LM left main coronary artery, RCA right coronary artery
