Which of the following is a risk factor for developing coronary artery disease?

A family history of heart disease is a significant risk factor for developing coronary artery disease. Genetics plays a crucial role in the predisposition to cardiovascular diseases. When immediate family members, such as parents or siblings, have experienced heart-related issues, it increases an individual's risk for similar conditions. This genetic component can influence various factors, such as blood cholesterol levels, blood pressure, and overall heart health.

In contrast, factors like a low cholesterol diet and regular physical activity contribute to heart health and are protective against coronary artery disease. Frequent medical check-ups can also help in the early detection and management of potential risk factors but do not inherently pose a risk themselves. Understanding the impact of genetic predisposition helps individuals assess their own risk and take preventive measures to maintain cardiovascular health.
