Frequency Of Poor Outcome (Death Or Poor Quality Of Life) After Left Ventricular Assist Device For Destination Therapy Results From The Intermacs Registry
CIRCULATION-HEART FAILURE(2016)
摘要
Background-A left ventricular assist device (LVAD) improves survival and quality of life for many, but not all, patients with end-stage heart failure who are ineligible for transplantation. We sought to evaluate the frequency of poor outcomes using a novel composite measure that integrates quality of life with mortality.Methods and Results-Within the INTERMACS (Interagency Registry for Mechanically Assisted Circulatory Support) national registry, poor outcome was defined as death or an average Kansas City Cardiomyopathy Questionnaire <45 during the year after LVAD (persistently limiting heart failure symptoms and poor quality of life). Among 1638 patients with LVAD, 29.7% had a poor outcome, with death in 22.4% and persistently poor quality of life in 7.3%. Patients who had a poor outcome were more likely to have higher body mass indices (29.3 versus 28.2 kg/m(2); P=0.007), lower hemoglobin levels (11.1 versus 11.4 g/dL; P=0.005), previous cardiac surgery (47.8% versus 39.8%; P=0.004), history of cancer (13.8% versus 9.7%; P=0.025), severe diabetes mellitus (15.6% versus 11.5%; P=0.038), and poorer quality of life preimplant (Kansas City Cardiomyopathy Questionnaire scores: 29.8 versus 35.3; P<0.001).Conclusions-Nearly one third of patients die or have a persistently poor quality of life during the year after LVAD. We identified several factors associated with a poor outcome, which may inform discussions before LVAD implantation to enable more realistic expectations of recovery.
