Figure 2: Comparison of TTFC (P <0,05; figure 2A) and TMBS (p <0,01; figure 2B) between patients whose perfusion scintigraphy showed a perfusion defect and patients whose did not; p-value <0,05. According to the graphs, patients with an ischemia demonstrated through the performance of a myocardial scintigraphy have much worse microvascular functionality indices, in comparison with patients whose nuclear imaging show no ischemic alterations at all.
