Table 4.

Unadjusted and adjusted change in myocardial flow reserve per Gray increase in mean cardiac radiation dose for all patients and for patients with no known ischemic heart disease. IHD = ischemic heart disease. LAD = left anterior descending. LCx = left circumflex. MFR = myocardial flow reserve. RCA = right coronary artery. SE = standard error.
