London: Scientists, including an Indian-origin researcher, have discovered what they claim are genetic glitches that put some at greater risk of heart attack and stroke, a finding which may pave the way for a genetic test for cardiovascular disease.
And experts warn that because most cases of heart disease are caused by lifestyle as opposed to genes, the creation of a simple gene test may do little to help the vastmajority of people who suffer from heart disease. Sandhu said: "For common diseases such as type 2 diabetes, heart disease and some cancers, with relatively small familial relative risks, it is unlikely that the discovery of all susceptibility loci genes will provide clinically useful risk prediction." Dr Samuli Ripatti from Helsinki University, who led the study, was quoted by the `Daily Express` as saying, "Genetic risk score improved risk reclassification in participants who were at intermediate risk on the basis of traditional risk factors. Whether this will have clinical usefulness remains to be seen." PTI
