Although resting left ventricular ejection fraction (LVEF) is routinely determined as part of the preoperative evaluation of patients undergoing coronary artery bypass graft (CABG) surgery, the value of repeating the LVEF determination after the surgery has not been established. To investigate whether the change in LVEF between pre- and early post-CABG had long-term prognostic significance, records for all 303 patients who underwent successful CABG surgery (no peri- or 30 day post-operative mortality) between 1982–1984 at our institution (WR) and had both pre- and postoperative first-pass radionuclide ventriculography were reviewed. The survival status of 255 patients (254 male) was determined from responses to mailed questionnaires, telephone interviews, and reviews of medical records and computerized death registries. Pre-CABG (mean 8.8 days) and predischarge (mean 7.4 days postCABG) LVEFs were tabulated, with an absolute change of ≥5% (increased or decreased) considered significant. Long-term survival probability was examined using Kaplan-Meier curves for three patient groups based upon preCABG LVEF: Normal (Nil: ≥47% (long-established value with camera used); Moderately reduced (Mod): 35–46%; Severely reduced (Sev): <35%.
