Predictors of Prehospital Delay
| Predictor | Hazard Ratio |
95% CI | p-value | |
|---|---|---|---|---|
| Black Race | 1.07 | 0.85 | 1.32 | 0.590 |
| Age | 1.00 | 1.00 | 1.01 | 0.260 |
| Sex | 0.93 | 0.78 | 1.12 | 0.470 |
| Diabetes | 1.23 | 1.01 | 1.49 | 0.036 |
| ACS Diagnosis | 1.31 | 1.09 | 1.56 | 0.003 |
| Greater number of symptoms | 0.51 | 0.44 | 0.61 | 0.001 |
| Greater symptom distress | 1.05 | 1.01 | 1.08 | 0.015 |
| Abrupt (vs. gradual) symptom onset | 1.41 | 1.18 | 1.68 | 0.001 |
Note: CI is confidence interval. ACS is acute coronary syndrome.
Hazard ratios > 1 indicate decreased delay time. Hazard ratios < 1 indicate increased delay time.
