Answers: Does the diagnosis R/O MI mean that the pt has had an MI?
No. R/o means "rule out." Any time someone has chest pain, it is essentially necessary to r/o MI.
It means the diagnosis of MI is under consideration and needs to be confirmed or excluded (ruled out) generally by further laboratory testing.
