Multivariable Logistic Regression for 28-Day Mortality (Adjusted for Admission APACHE II Score, Mechanical Ventilation at Time of Echocardiogram, Receipt of Fluid and Vasopressor Dose at Time of Echocardiogram)
| Variable | OR | 95% CI | P |
|---|---|---|---|
| RV dysfunction | 3.37 | (1.67-6.78) | .001 |
| LV systolic dysfunction | 0.63 | (0.32-1.24) | .32 |
| LV diastolic dysfunction | 1.26 | (0.64-2.50) | .51 |
| APACHE II | 1.09 | (1.04-1.13) | <.001 |
| Ventilated during echo | 0.48 | (0.19-1.17) | .11 |
| Pao2/Fio2 ratio | 1.00 | (1.00-1.00) | .29 |
| NEE dose (per 0.01 μg/kg/min increase) | 1.02 | (1.01-1.04) | .01 |
| Fluid 6 hours before echo, mL | 1.00 | (1.00-1.00) | .41 |
Area under receiver operating characteristic curve = 0.77. For patients on multiple vasopressors, all doses were converted to norepinephrine-equivalent doses, per previously described methods.28 APACHE = Acute Physiology and Chronic Health Evaluation; LV = left ventricle; NEE = norepinephrine equivalent.
