Which of the following findings would be considered a high-risk indicator for coronary artery disease?

A family history of coronary artery disease (CAD) is considered a high-risk indicator because genetics play a significant role in the predisposition to heart conditions. Individuals with a first-degree relative who has had heart disease—especially at a young age—are more likely to develop CAD themselves due to inherited risk factors. This familial linkage can be tied to shared genetic traits, lifestyle factors, and environmental influences that increase the risk of atherosclerosis and other heart-related issues.

In contrast, normal blood pressure is generally indicative of lower risk, as hypertension is a major risk factor for CAD. Low LDL cholesterol is also protective against heart disease; lower levels are associated with a reduced risk for cardiovascular events. Regular exercise contributes positively to heart health by improving circulation, reducing weight, and enhancing overall cardiovascular function, thus also lowering the risk of developing CAD. Therefore, family history stands out as a significant warning sign that warrants further attention and proactive management regarding coronary artery disease risk.
