Abstract
This research synthesis analyzed research on spirituality in cardiac illness from 1991 to 2004 to identify progress, gaps, and priorities for research. Articles were retrieved from PubMed and CINAHL. Twenty-six studies met inclusion criteria. Moody's Research Analysis Tool, Version 2004, was used to analyze studies. Lack of conceptual model and universal definition of spirituality are major knowledge gaps. A proposed conceptual model is presented.
