Shi Y, Pedersen R, Rappelt MW, et al. Risk Stratification Of Patients Undergoing Major Non-Cardiac Surgery and Implications Of Preoperative Echocardiography. Journal of the American College of Cardiology (JACC). 2016; 67(13S):1458-1458.
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
