The diagnosis of a cardiac illness and subsequent adjustment to a permanently altered lifestyle have profound impact on patient and family. Nurses are in a key position to support the cardiac family during crisis and assist them in recovery. Within the group environment, the nurse can clarify perceptions of the cardiac event, explore alternative coping strategies, and facilitate the development of new social supports.

It focuses on assessment, planning, implementation, and evaluation strategies with recommendations for future research.
