Comparison of CMR data between athletes demonstrating de-novo ECG changes and athletes undergoing a mandatory CMR
| Athletes undergoing mandatory CMR assessment (n=30) | Athletes demonstrating de-novo ECG changes undergoing CMR assessment (n=17) | P value | |
| Age (years) | 26 (19–30) | 22 (19–25) | 0.094 |
| BSA (m2) | 2 (1.9–2.1) | 2 (1.9–2.1) | 0.861 |
| Symptom duration (days, 0=asymptomatic) | 0 (0–3) | 5 (3–10) | 0.0001* |
| Positive PCR to ECG | 11 (11–11) | 12 (10–14) | 0.298 |
| Positive PCR to CMR | 11 (11–11) | 15 (11.5–19.5) | 0.005* |
| LVMWT (mm) | 10 (9–10) | 9 (9–11) | 0.770 |
| LVEF (%) | 59 (57–62) | 60 (57–64.3) | 0.415 |
| LV mass indexed (g/m2) | 72 (54–83) | 82 (65–93) | 0.094 |
| RVEF (%) | 53 (51–60) | 58 (51–62.5) | 0.179 |
| Presence of inflammatory cardiac sequalae | 0 | 15 |
Values are expressed as median (IQR).
*P value <0.05 deemed statistically significant.
BSA, body surface area; CMR, cardiac magnetic resonance; LV, left ventricular; LVEF, left ventricular ejection fraction; LVMWT, left ventricular maximal wall thickness; RVEF, right ventricular ejection fraction.
