Re: Silent heart attack or unstable angina?

Hi dee,

Angina is chest PAIN due to insufficient supply of blood/oxygen to the heart muscle. Stable indicates pain with exertion, but goes away with rest. Unstable indicates pain even at rest.

A heart attack is the result of an insufficient supply of blood to the heart with the result of muscle damage. Angina may or may not be present during a heart attack (myocardiac infraction, MI)
