A member asked:
Can any doc tell me what's the difference between an angina attack, a heart attack and a cardiac arrest?
A doctor has provided 1 answer
Lots.: Angina: discomfort from imbalance between oxygen supply and demand in the heart, but no muscle death. Heart attack: supply/demand imbalance so prolonged and severe that part of the heart muscle dies. Cardiac arrest: heart function so poor (bad pumping rhythm, no pumping rhythm, electrical rhythm but no actual pumping, etc) your circulation essentially stops.
