The Evaluation of Preoperative Right Ventricular Diastolic Dysfunction on Coronary Artery Disease Patients with Left Ventricular Dysfunction

摘要: Objective Early death following coronary artery bypass graft (CABG) surgery tends to occur in heart disease (CHD) patients with significantly decreased left ventricular function. Methods The clinical data of 231 preoperative ejection fraction (LVEF) ≤35% who underwent CABG were retrospectively analyzed from June 2007 October 2012. The divided into 2 groups: group A contained 39 suffered early postoperative and B 192 had a successful outcome. Results Multivariate analysis demonstrated that only right (RV) diastolic function (increase Et/Et′) lack suitable target vessels independent risk factors for after severely impaired (P = 0.003 0.002, respectively). Other factors, including age, intra-aortic balloon pump (IABP) implantation, ischemic mitral regurgitation (IMR) treatment, atrial internal diameter, end-diastolic not associated CABG. Preoperative Et/Et′ ≥10 was (χ2 = 11.55, P < 0.001, odds ratio [OR] = 17.54, 95% confidence interval [CI]: 2.12–383.16). Conclusion Decreased RV are function. Therefore, assessment will be helpful predicting these patients. Additionally, is
