Implications of genetic testing for sudden cardiac death syndrome

The completion of the Human Genome Project in 2003 is shifting the focus of modern health care from disease management based on clinical signs to genomic-based treatment and prevention. Nurses at all levels of practice are going to increasingly come under pressure to deliver evidence-based, competent care to families undergoing genetic testing for hereditary conditions (Skirton and Barnes, 2005). A new chapter added to the National Service Framework for Coronary Heart Disease in 2005 raised awareness of the genetic basis of up to 400 sudden cardiac deaths that occur every year in the UK (Department of Health, 2005). This article addresses some of the clinical and ethical implications for nurses caring for families who may be at risk of an inherited sudden cardiac death syndrome. Nursing practice implications are discussed, concluding that more research is needed to explore how family members cope with genetic information which will shape the provision of future genetic healthcare.
