Abstract
Depression and anxiety disorders are prevalent in patients with heart failure. They are associated with adverse effects such as rapid disease progression, poor medication compliance, low quality of life and increased mortality rate. The current literature review aims to provide an overview of the overall rate of depression in patients who receive left ventricular assist device (LVAD) implantation and identify the psychological phases that these individuals experienced peri- and post-LVAD implantation. A PubMed search using regular and Medical Subject Headings (MeSH) keywords identified 239 articles. After applying inclusion/exclusion criteria, removal of duplicate studies, and careful review of articles, 40 studies provided relevant information on our primary end-point. These 40 studies selected include 13 paid articles with abstracts and 27 free full-text articles comprising eight prospective cohort studies, five retrospective cohort studies, six cross-sectional studies, one qualitative study, one randomized clinical trial, one systematic review, four literature reviews, and one practice guide. Our review shows that patients experienced different psychological phases after LVAD implantation. However, as the time from implantation progressed, these patients showed a significant improvement in depression, anxiety, and health-related quality of life.
