Chen, a 78-year-old male has a long history of cardiovascular disease. Recently, he has developed “blue lines” bilaterally, distal to the knees. He is worried that this could be a sign of another heart attack or something similar, so he decides to seek treatment.

Chen reports that his right leg hurts, especially during and after exercise.   Chen reports that his father had varicose veins. Chen reports that he is mostly sedentary and spends a lot of time watching TV or playing board/card games. His BMI is 24, BP is 130/78, and pulse is 68.   Which part of Chen’s medical information is most likely NOT a risk factor for varicose veins?   Body mass index   Sedentary lifestyle   Family history   Cardiovascular disease
