Abbreviations: RVD, right ventricular dysfunction; LVEF, left ventricular ejection fraction; CHF, congestive heart failure; CVA, cerebrovascular accident; pulmonary HTN, pulmonary hypertension; RVSP, right ventricular systolic pressure; OR, odds ratio; CI, confidence interval.

Logistic regression was performed to estimate OR, 95% CI, and p-value. Only covariate that is individually associated with outcome with a p value < 0.1 was included in the multivariable model. Only LVEF was included in the multivariable model because of multi-collinearity.
