Acute CMR Characteristics Between Patients Who Completed Paired Acute and Follow‐up Scans (n=40) and Patients Who Only Had the Acute Scan (n=8)
| Patients With Paired CMR (n=40) | Patients With Acute CMR Only (n=8) | P Value | |
|---|---|---|---|
| Acute LV EDV, mL | 172±38 | 135±28 | 0.01a |
| Acute indexed LV EDV, mL/m2 | 87±13 | 73±13 | 0.01a |
| Acute LV ESV, mL | 90±30 | 66±20 | 0.04a |
| Acute indexed LV ESV, mL/m2 | 45±13 | 36±11 | 0.07 |
| Acute LV EF, % | 49±8 | 52±8 | 0.32 |
| Acute LV mass, g | 111 (92–124) | 137 (86–154) | 0.28 |
| Acute MI size, % of LV | 28 (14.8–38.0) | 24.0 (23.0–25.8) | 0.52 |
| AAR, % of LV | 42.0±12.0 | 46.4±10.9 | 0.34 |
| MVO, % | 26 (65%) | 5 (63%) | 0.60 |
| Acute T2Remote, ms | 50 (48–52) | 49 (48–54) | 0.78 |
| Acute T1Remote, ms | 1026 (990–1077) | 1043 (963–1095) | 0.80 |
| Acute ECVRemote, % | 28.1 (26.2–29.7) | 27.6 (26.2–31.2) | 0.73 |
AAR indicates area‐at‐risk; CMR, cardiovascular magnetic resonance imaging; EDV, end diastolic volume; EF, ejection fraction; ESV, end systolic volume; LV, left ventricle; MVO, microvascular obstruction.
