Abstract

Background: Preoperative risk assessment for major non-cardiac surgery focuses on ischemic heart disease, not heart failure. We examined whether transthoracic echo (TTE) parameters are associated with 6 month mortality.

Methods: 1,770 patients who had TTE within 90 days prior to surgery (n=192 with LVEF≤40%) were retrospectively identified and followed for 6 months. Descriptive statistics were used to compare populations and Cox proportional hazards were used for univariate and multivariate models.

Results: 6 month mortality was higher in patients with LVEF≤40% (Figure 1). In this group, univariate and multivariable models associated with mortality are shown in table 1.

Conclusions: Preoperative LVEF
