Is it possible to have blocked arteries at the age of 23?

Yes: Although rare, it can happen. Some of the possible causes are buerger's disease (blockage of small arteries related to smoking), vasculitis, severe raynauds disease (vasospasm from cold exposure), collagen vascular disease, embolism, popliteal entrapment or popliteal adventitial cystic disease.

Yes: Vessels can be blocked by trauma or congenital problems like popliteal artery entrapment or thoracic outlet syndrome. Pad is rare in this age group. Juvenile diabetics are at increased risk.

Blocked arteries: Very unlikely at age 23

Yes: It is quite uncommon, but we have treated people with heart attacks due to coronary artery blockage in their mid 20's. If you have chest pain, there are other cardiac causes in younger people such as heart rhythm problems or if you were born with coronary arteries which travel in a different pattern to supply blood flow to your heart (congenital anomalous origin of the coronary arteries).
