Stent after a heart attack. Feeling dizzy and often get chest pain, could anxiety cause these symptoms or there can be another attack?

I am a 40-year-old male. Last year I had a stent after a heart attack. I am starting to feel dizzy and often get chest pain, went back to the hospital once because I thought I was having another heart attack but was ok, and visit a doctor frequently but I still feel dizzy, could anxiety cause these symptoms?
