Characteristics That May Identify An Individual with a Genetic Predisposition to Cardiovascular Disease Positive Family History Disease in a first-degree relative Parents, siblings Disease in female relatives Disease in the absence of other recognized risk factors Early age-at-onset Genetically determined risk often characterized by an earlier age-at onset Hyperlipidemia resistant to dietary intervention
