Fig. 1.

Pie charts show disease distribution among the 3 main coronary arteries in STEMI, NSTEMI, and stable AP. Note the higher prevalence of the LAD and the lower prevalence of the LCx only in STEMI, versus the more even distribution in NSTEMI, stable AP, and total obstructive CAD (narrowing, ≥50%).

AP = angina pectoris; CAD = coronary artery disease; LAD = left anterior descending coronary artery; LCx = left circumflex coronary artery; NSTEMI = non-ST-segment-elevation myocardial infarction; RCA = right coronary artery; STEMI = ST-segment-elevation myocardial infarction
