What treatment options are likely for hardening of the arteries

Hi, thanks for the information - yes I went for a cardiac perfusion imaging test & the doctor in nuclear science told me that the test indicated hardening of the arteries, (& suggested I refrain from strenuous activity until I speak to my physician). I have not seen my doctor yet to discuss the results as he will not receive the report until next week. I wanted to know what questions to ask when I do see him.
