Degree of coronary artery calcification by myocardial flow reserve tertile in patients with normal myocardial perfusion imaging

MFR < 1.71 (n = 29) 1.71 ≤ MFR ≤ 2.24 (n = 29) MFR > 2.24 (n = 29) p value
No CAC 13 (45%) 14 (48%) 16 (55%) 0.80
Mild CAC 8 (28%) 8 (28%) 8 (28%) 1.00
Moderate CAC 7 (24%) 4 (14%) 5 (17%) 0.69
Severe CAC 1 (3%) 3 (10%) 0 (0%) 0.32

There were no statistically significant differences in either the overall presence or severity of coronary artery calcification seen on transmission computed tomography scans between the myocardial flow reserve tertiles.

CAC, coronary artery calcium; MFR, myocardial flow reserve.
