A large research literature attests to the positive influence of spirituality on a range of health outcomes. Recently, a growing literature links spirituality to improved recovery from cardiac surgery. Cardiac surgery has become an increasingly common procedure in the United States, so these results may provide a promising indication for improved treatment of patients undergoing surgery. To our knowledge, a comprehensive review of the literature in this area does not exist. Therefore, this paper reviews the literature relevant to the influence of spirituality on recovery from cardiac surgery. In addition, it proposes a conceptual model that attempts to explicate relationships among the variables studied in the research on this topic. Finally, it discusses limitations, suggests directions for future research, and discusses implications for the treatment of patients undergoing cardiac surgery.
