Variables associated with 30-day mortality after adjustment (Cox multivariate analysis, model 1).
| Hazard Ratio | 95% Confidence Interval | p | |
|---|---|---|---|
| Age (per year) | 1.03 | 0.99–1.07 | 0.073 |
| Sex male | 5.70 | 1.85–17.51 | 0.002 |
| Diabetes | 1.51 | 0.68–3.56 | 0.309 |
| Acute myocardial infarction at admission | 2.79 | 1.29–6.03 | 0.009 |
| LVEF (per %) | 0.99 | 0.97–.01 | 0.349 |
| Lactate level (per one unit) | 1.17 | 1.10–1.25 | <0.001 |
| Creatinine level (per one unit) | 1.04 | 1.01–1.08 | 0.026 |
| Hemoglobin level (per one unit) | 0.92 | 0.81–1.05 | 0.236 |
| VA-ECMO first | 0.25 | 0.10–.65 | 0.004 |
Cox model: age, sex, diabetes, acute myocardial infarction at admission, left ventricle ejection fraction, lactate level, creatinine level, hemoglobin level, VA-ECMO first; variables of interest were selected based on the previous literature. LVEF = left ventricular ejection fraction; VA-ECMO = veno-arterial membrane oxygenation.
