Risk factors for coronary heart disease include each of the following except:

The answer is based on understanding how different factors contribute to the risk of developing coronary heart disease. High-density lipoprotein (HDL) cholesterol is often referred to as "good" cholesterol because higher levels are generally associated with a lower risk of heart disease. An HDL level greater than 60 mg/dL is considered protective against coronary heart disease rather than a risk factor. This is because HDL helps transport cholesterol away from the arteries and back to the liver for disposal, thus helping to prevent the accumulation of plaque that can lead to atherosclerosis.

In contrast, hypertension, smoking, and family history are established risk factors for coronary heart disease. Hypertension increases the workload on the heart and can damage blood vessel walls. Smoking introduces toxins that can lead to arterial damage and promote the development of plaque. Family history indicates a genetic predisposition to heart diseases, increasing the likelihood one will develop similar conditions.

Therefore, identifying HDL levels above 60 as not being a risk factor reflects the understanding of its protective role in cardiovascular health.
