All of the following are modifiable risk factors for coronary artery disease (CAD) EXCEPT

  1. high stress.
  2. obesity.
  3. smoking.
  4. family history.
Number 4 is correct.
Modifiable risk factors are lifestyle changes a person can make in order to reduce their risk of developing a certain disease. A high-stress lifestyle, smoking, and obesity are all modifiable risk factors for CAD. Risk factors such as age, gender, race, and family history are nonmodifiable.
