When is an appropriate time to consider genetic testing for cardiomyopathies for athletes as part of risk stratification for sudden cardiac death, in light of heightened prevalence of cardiac remodeling confounded by exercise and athletic conditioning?  

Genetic testing for cardiomyopathies in athletes may be appropriate in the presence of structural cardiac abnormalities with known genetic basis documented by imaging or a family history of an index case of sudden cardiac death with documented genetic basis in a relative preferable first or second d...

I'm assuming this question is referring to proactive genetic screening rather than evaluation of a patient with clinical signs of heart disease. Clinical screening with EKG, echo and history including family history is a much more effective method of risk stratification. UK Biobank exome sequencin...
