Why would someone run fever a week after having cardiac stents inserted?

My husband had 3 stents put in arteries a week ago. He was sent home with about seven prescriptions, but none of them were anti-biotics. He has been running a low grade fever since day two. When we called the cardiologist, he said that we should worry until his fever reached 101.5 and then we should go immediately to the ER. Has anyone else ever experienced this or know anything about it? Also, incredibly after the procedure and even with blood pressure meds, his bottom number is stayng in the 90s?

Just with my general medical background I'll give you a partial answer.

Fever is a sign of an infection. Fever is our body's way of fighting an infection. So a low fever is a GOOD thing. It's your body working as it should. A low grade fever should not be treated.
