In technical terms I heartily agree thatcoronary thrombosis [med.] - die Koronarthrombose
is the blockage of a coronary artery by blood clot, which often leads to myocardial infarction (tissue destruction).
Colloquially, however, both myocardial infarction and coronary thrombosis may be referred to as heart attacks.
“The popular use of coronary as a synonym for heart attack, as in an article that asks “Is it safe for them to continue a normal sexual life after a coronary?” is colloquial and is not usually encountered in scientific or medical writing.”
The American Heritage® Dictionary of the English Language, 5th edition Copyright © 2013 by Houghton Mifflin Harcourt Publishing Company.
Coronary here is being used in a shortened form of "coronary thrombosis" as a synonym for a heart attack.
> Ich wäre ja dafür, [med] als Domäne bei heart attack zu streichen, da es sich nicht um einen Fachterminus handelt.
I don’t agree. #2 was written in 2005, but even then the simpler term “heart attack“ was in technical use and is even more so today.
