Silent heart attack or unstable angina?
 
Hi, are there similar or different symptoms when experiencing a silent heart attack or an episode of unstable angina? I'm not sure if the onset of symptoms are different, accept for the diagnosis.

Thanks in advance for any information and advice.

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)

Hi kenkeith,

would <muscle damage> include an enlarged heart and/or heart failure?

dee,


Silent heart attack doesn't hurt...unstable angina does!

Muscle damage would impede heart contractions and could interfere with electric impulses and cause irregular heartbeats.

The damaged heart to compensate for weak contractions could/would enlarge and require treatment. Without intervention and proper treatment the heart pumped into circulation would eventually be reduced to an output of less than 29%, and that would be in the heart failure range.

Heart failure and an enlarged heart is not always just a consequence of a heart attack (MI). Heart failure can develop from other causes, i.e. heart valve stenosis (restricted output by a narrowed opening), valve regurgitation (some backflow of blood resulting in not enough blood getting into circulation), etc.
