At what age is a father or brother considered high risk for coronary artery disease (CAD) history?

A father or brother is considered high risk for coronary artery disease (CAD) if they have a history of the disease before the age of 55. This threshold is based on the understanding that early-onset CAD in male first-degree relatives (which includes fathers and brothers) significantly increases an individual's risk for developing CAD themselves. Identifying family history, especially at a younger age, is crucial for assessing risk factors and implementing preventative strategies.

Risk factors in men under 55, including lifestyle, hypertension, hyperlipidemia, and diabetes, can guide clinicians in recommending early screening and lifestyle modifications. Therefore, early awareness of these risks aids in better management and preventive care for those with a family history of CAD.
