A milleSievert is a measurement of the amount of radiation absorbed so whether it hits your heart or anywhere else is irrelevant. The heart is made of muscle and far more resistant to the effects of radiation than many other tissues.

A healthcare worker is allowed to receive 50 mSv each and every year. Even looking at those people who have got close year after year for 40 years there is scant evidence of harm. Every long haul flight gives you 0.1 to 0.3 mSv. So you are worrying about a test that gives you the same exposure at perhaps only ten flights.

Everyone seems happy there is no risk of coronary issues so I would put the issue to bed and forget it. Should there be a problem you would most likely get a change of symptoms and we normally just send these people for a same day CTA. Most likely you will get no change, not have an issue, and fly for many years absorbing radiation with no consequences.
