Answers
Explanation:
A heart attack occurs when an artery supplying your heart with blood and oxygen becomes blocked. Fatty deposits build up over time, forming plaques in your heart's arteries. If a plaque ruptures, a blood clot can form and block your arteries, causing a heart attack
Answer:
HEART ATTACK;
A blockage of blood flow to the heart muscle.
A heart attack is a medical emergency. A heart attack usually occurs when a blood clot blocks blood flow to the heart. Without blood, tissue loses oxygen and dies.
CAUSE:Heart attacks are caused by the blood supply to the heart being suddenly interrupted. Without this supply, heart muscles may be damaged and begin to die.
Without treatment, the heart muscles will experience irreversible damage.
If a large portion of the heart is damaged in this way, the heart stops beating (known as a cardiac arrest), resulting in death.
