A 28-year-old man admitted with angina pectoris, CAD-RADS 5. (a) Image showed coronary artery calcification score of 0; (b) MPR revealed the anterior descending branch lumen obstruction (arrow); (c) curves of myocardial strain and time in the cardiac cycle. The peak systolic strains of the left ventricular myocardium were markedly decreased. Red, blue, green represents myocardial global radial strain, global longitudinal strain, and global circumferential strain respectively.
