Abstract
Early readmission (within 30 days) after left ventricular assist device (LVAD) implantation might be a marker for increased mortality. We retrospectively reviewed the records of 277 adults who underwent continuous-flow LVAD implantation from 2005 through 2015 at our institution. The baseline characteristics of patients who were (versus were not) readmitted within 30 days after LVAD implantation were compared. To assess the impact of 30 day readmission on long-term survival, we used multivariate Cox regression. We also compared the cardiac transplant rate between the two groups. Of the 277 patients, 217 (78.3%) underwent LVAD implantation as a bridge-to-transplant; 76 (27.4%) of the 277 were readmitted within 30 days. The most common reason for readmission was volume overload (23.6%), followed by gastrointestinal bleeding (15.8%). Male gender, previous smoking, a higher baseline creatinine level, higher Model for End Stage Liver Disease Excluding INR (MELD-XI) score, and postoperative gastrointestinal bleeding or stroke were each associated with 30 day readmission. In our final multivariate model, increased mortality was also associated with 30 day readmission (hazard ratio, 1.60; 95% confidence interval, 1.1-2.5). Among the 217...Continue Reading
