Table 3. Independent Predictors of ACVE.

Risk Factor	OR (95% CI)	Adjusted OR* (95% CI)
QTc, (> 500 ms)	25.7 (12.2-54.1)	27.6 (11.1-69.1)
Bicarbonate, (<20 mEq/L)	10.7 (5.9-19.4)	4.4 (2.1-9.1)
Prior cardiac disease, (CAD or CHF)	9.5 (5.6-16.4)	9.5 (4.9-18.4)

^*Multivariable model adjusted for: altered mental status, age, sex, and ED site.

CAD = coronary artery disease; CHF = congestive heart failure; OR = odds ratio; mEq/L = milliequivalents per liter; ms = milliseconds

ACVE = adverse cardiovascular events; QTc = Bazett's corrected QT interval
