Relative risk of 30 day mortality after acute myocardial infarction: results of multivariate analyses with non-dyskinetic wall motion index (ND-WMI)
| Relative risk (95% CI) | p Value | |
|---|---|---|
| *Relative risk is per unit for continuous variables. | ||
| †Patient delay is time from start of symptoms until arrival at hospital. | ||
| AMI, acute myocardial infarction; CI, confidence interval; WMI, wall motion index. | ||
