Figure 3: Comparison of cTFC between the vessel responsible for the scintigraphic perfusion defect and the average of the values relieved on the other two major branches; p-value <0.0001. As shown, heart cath confirms the reliefs of scintigraphic images notwithstanding the indemnity of subepicardial vessels, by showing in the artery responsible for the perfusion defect much worse indices of microvascular functionality in comparison to the average of the other two major branches.
