Preexisting Right Ventricular Diastolic Dysfunction and Postoperative Cardiac Complications in Patients Undergoing Nonemergency Coronary Artery Bypass Surgery.

摘要: Objectives To evaluate whether the presence of preexisting right ventricular diastolic dysfunction (RVDD) in patients undergoing coronary artery bypass grafting (CABG) is associated with a greater incidence postoperative cardiac complications. Design Single-center, observational, retrospective, cohort study. Setting Research institute hospital. Participants Patients CABG from February 2017 to November 2018 (n = 200). Interventions None. Measurements and Main Results Transthoracic echocardiography was performed obtain following values (RV) function: peak velocity early (Et) late (At) transtricuspid flow, e't, a't, s't, tricuspid annular plane systolic excursion, RV Tei index. All were divided into 2 groups: RVDD (n = 92) or without (n = 108). Compared control patients, developed heart failure (PHF) (primary outcome) more frequently (p = 0.026). RVDD, low left ejection fraction, female, underwent cardiopulmonary bypass, increased mass index, an Et/At ratio that risk development PHF. However, only (odds 4.82; p = 0.015), 4.04; p = 0.028), female sex independently PHF multivariate analyses. Conclusions Preoperative are independent factors for after disease patients. The decreased best echocardiographic marker predicting CABG. Nevertheless, possibility assessing preoperative function predict requires confirmation additional studies.
