Mending broken hearts: the role of spirituality in cardiac illness: a research synthesis, 1991-2004.

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.
