Subject: What are heart failure, heart attack and cardiac arrest?
Though all types of heart trouble pose emergency threats to people's health, there are many differences between them in terms of both causes and symptoms. "Heart failure" refers to some loss of the heart's successful function as a pump; "congestive heart failure" applies more specifically to when blood flow has backed up, causing the swelling of veins. A "heart attack" occurs when blood flow to the heart is cut off - sometimes, this is caused by a spasm. But if the heart suddenly stops beating, that is a "cardiac arrest", and is a problem with the timed electrical signals that make the heart contract.
- Singer George Michael passed away on Christmas Day, at age 53.
- His manager, Michael Lippman, cited heart failure as the cause of death.
- If Michael's heart not only failed but also stopped beating entirely, he would have had minutes for doctors to intervene.
"Blockages causing heart attacks are mostly caused by a buildup of plaque in the arteries."
