Clinical and Electrocardiographic Predictors of NSTEMI and MACE
| Univariate OR (95% CI) | Multivariate OR (95% CI) | |
|---|---|---|
| Predictors of NSTEMI upon ED admission* | ||
| Baseline characteristics | ||
| Age (per 10-year increment) | 1.2 (1.0 to 1.5) | NS |
| Clinical diagnostics | ||
| HDL (per 5 unit increment) | 0.90 (0.77 to 0.95) | NS |
| Creatinine (per 0.1 unit increment) | 1.05 (1.01 to 1.09) | NS |
| Ejection fraction (per 10% increment) | 0.63 (0.51 to 0.79) | NS |
| Presenting 12-lead ECG | ||
| Any ST depression | 2.7 (1.4 to 5.1) | NS |
| T wave complexity (per 1% increment) | 1.03 (1.02 to 1.05) | 1.03 (1.01 to 1.05) |
| Predictors of MACE during hospitalization† | ||
| Baseline characteristics | ||
| Male sex | 2.7 (1.0 to 7.2) | NS |
| Known CHF | 4.1 (1.4 to 12.0) | NS |
| Clinical diagnostics | ||
| Creatinine (per 0.1 unit increment) | 1.05 (1.01 to 1.09) | NS |
| B-type natriuretic peptide (per 100 units) | 1.11 (1.05 to 1.12) | NS |
| Presenting 12-lead ECG | ||
| Any ST depression | 2.3 (0.8 to 5.9) | NS |
| T-wave complexity (per 1% increment) | 1.04 (1.01 to 1.06) | 1.04 (1.01 to 1.06) |
CHF indicates congestive heart failure; CI, confidence interval; ED indicates emergency department; HDL, high-density lipoprotein; MACE, major adverse cardiac events; NS, not significant; NSTEMI, non-ST elevation myocardial infarction; OR, odds ratio.
