| Diabetes | 1.36 (0.47-2.25) | .003 |
| Hypertension | −0.36 (−1.02 to 0.31) | .29 |
| Current smoking | −0.62 (−1.29 to 0.06) | .07 |
| Time from symptom onset to device (per 1 h) | 0.32 (0.06-0.58) | .02 |
| Baseline TIMI flow grade ≤1 (vs ≥2) | 2.08 (1.39-2.76) | <.0001 |
Estimates and 95% CI were estimated using multiple linear models.
