Cardiovascular Genescreen(TM)

Scientific rationale

The Cardiovascular Genescreen combines diagnostic genetic testing with the integrative sciences of pharmacogenetics and nutrigenetics for targeted risk reduction intervention. The detection of genetic variation is interpreted together with a medical and lifestyle assessment to identify a combination of risk factors that, if left untreated, could cause or contribute to disease development. This approach is based on the knowledge that a single genetic risk factor  such as heterozygous familial hypercholesterolaemia (FH) is not sufficient to cause cardiovascular disease (CVD). Treatment guided by genetic testing is aimed at reducing the risk of disease development or recurrence.

A recent study published in the New England Journal of Medicine has provided solid proof that assessment of a combination of carefully selected genetic markers could improve the determination of risks to individuals beyond standard clinical indicators. While each individual marker may exert a modest effect in isolation, a combination of functional genetic variations may have a substantial influence on the development or progression of particular medical conditions in any specific population.
