What are considered non-modifiable risk factors for coronary heart disease?

The correct answer focuses on non-modifiable risk factors for coronary heart disease, which are characteristics that cannot be changed or altered by lifestyle or behavioral changes. Age and family history are key examples of these factors.

As individuals age, their risk for developing coronary heart disease naturally increases due to various biological and physiological changes that occur in the body over time. Family history refers to the genetic predisposition to heart disease, as having close relatives with a history of cardiovascular issues can raise one's own risk, regardless of individual lifestyle choices.

In contrast, the other choices consist of modifiable risk factors. Conditions such as obesity, inactivity, smoking, elevated LDL cholesterol levels, high blood pressure, and diabetes can all be addressed through lifestyle modifications, medical interventions, or a combination of both. Understanding the distinction between modifiable and non-modifiable risk factors is crucial for developing effective strategies in prevention and management of coronary heart disease.
