A 33-year-old member asked:

Can someone drive home after a myocardial perfusion scan?

2 doctor answers6 doctors weighed in
Dr. Thomas Heston
Family Medicine 29 years experience
Yes: You can drive home unless you are administered a medication for relaxation during the test as is sometimes necessary for people with severe claustrophobia. However, this is very, very rare because nuclear cameras are so open. Nearly 100% of the people who get a myocardial perfusion scan can drive home safely after the test.

What are the risks in having a myocardial perfusion scan?

Dr. Samuel Hahn
Cardiology 28 years experience
Minimal : There is a small amount of radiation from the scan but it is less than from a cat scan. If you do an exercise stress test, there is a small risk from the exercise portion but you are continuously monitored for any problems. Your job is to report any difficulties or symptoms during the test.

Can I buy anything that will prevent me from breathing cigarette smoke?

No and Yes: Well you do not need to buy anything, but stay away from smokers and not smoke yourself. If there was something like this available, it would make someone very wealthy. Seems i read the most powerful toxic fume masks used by industrial folks working with hazardous fumes will only block about 90% of nearby cigarette smoke. Would not quote that figure.
