Purpose of our study was to investigate the association of the extent of MI localized by gadolinium enhanced MRI, and the quantity of calcium in the coronary arteries detected with CT. Of the 674 subject, 21% had evidence of MI. Subjects with MI in all three coronary distributions had higher coronary calcium score (CCS), compared to those with MI in only one. Those with only one or two infarcted segments had significantly lower CCS than those with infarct in three or more segments. The relationship between the extent of MI and quantity of coronary calcium is significant and strong.
