Dallas AMI cohort [4]: culprit artery in relation to the location of the AMI.

	Inferior AMI (𝑛=107)	Anterior AMI (𝑛=71)
RCA	88 (82.2%)∗	0
LCX	13 (12.1%)	2 (2.8%)
LAD	4 (3.7%)	69 (97.1%)†
LCX/LAD	1 (0.9%)	0
Ramus branch	1 (0.9%)	0

AMI: acute myocardial infarction; LAD: left anterior descending artery or its branches; LCX: left circumflex artery or its branches; RCA: right coronary artery or its branches.
