Myocardial perfusion evaluation in the three groups.
| TC (N = 27); n (%)/median (interquartile range) | MVA (n = 27); n (%)/median (interquartile range) | CG (n = 27); n (%)/median (interquartile range) | p value (TCvsCG/TCvsMVA/MVAvsCG) | |
|---|---|---|---|---|
| Blush LAD | 19 (70%) | 27 (100%) | 27 (100%) | 0,001/0,001/NS |
| QuBE LAD | 8,9 (7,2–11,5) | 13,5 (10–16) | 11,4 (10–15,7) | 0,008/0,006/NS |
| Blush 3 RCA | 26 (96%) | 27 (100%) | 27 (100%) | NS∗ |
| QuBE RCA | 10 (7,7–12,4) | 11 (9–15,4) | 10,5 (7,7–13) | NS∗ |
| Blush 3 LC | 27 (100%) | 26 (96%) | 27 (100%) | NS∗ |
| QuBE LC | 10,4 (7,1–12,8) | 13 (10–17) | 11,5 (9,5–15) | NS∗ |
TC: Takotsubo cardiomyopathy; MVA: microvascular angina; CG: control group; TFC: TIMI frame count; QuBE: Quantitative Blush Evaluator; LAD: left anterior descending coronary artery; RCA: right coronary artery; LC: left circumflex coronary artery; ∗ indicates the same result for all the three matches.
