Family History Strongly Predicts Hidden Coronary Atherosclerosis
- A family history of premature coronary disease markedly increases the prevalence of high-risk atherosclerosis on coronary CT angiography.
- In the FREIGHTER study, 62% with family history had high-risk disease vs 43% without; even 'very low risk' with family history showed 42% disease.
