What can cause a heart attack?
Imagine A and B are both arteries leading to the heart. B is partially clogged by plaque build up.() A() BThe lower one (b.) is semi-clogged and thus does not provide as much oxygen to muscles such as the heart. The Heart muscle will begin to die if not treated quickly.
Can a 16 year old have a heart attack and how long does it take for heart attack to occur if you have arm pain?
Anyone can suffer from a heart attack and it could only be minutes for the heart attack to kick in.
Can you have a heart attack after quitting smoking for a long time?
Yes, you can have a heart attack even if you quit smoking many years ago. Not all heart attacks occur in smokers. Smoking increases the risk of a heart attack, though. Within eight to 15 years of quitting smoking, your risk of heart attack is at the same level as that of nonsmokers.
What happens during a heart attack?
In a heart attack (myocardial infarction) the heart is deprived of oxygen, and this eventually causes necrosis of the deprived cardiac tissues. This tissue death can result in heart failure and deadly arrhythmia.Basically plaque builds up in the coronary artery and when the plaque hardens it explodes and platelets (cells that help to clot arteries and veins when they are cut) come in and prevent further release of the plaque that has explodes. However, this clotting can block an artery completely and stop blood flow to a part of the heart. When the blood flow stops, so does the oxygen to that part of the heart. Because of the lack of oxygen to keep the muscle going, muscle cells die in the heart, that's what happens in the heart during a heart attack!When you have a heart attack the heart stops beating. It's because it clogs up the heart and you sometimes you will die or have brain damagewhen you have a heart attack some of your heart cells stay without oxygen (Hypoxia )which may hurt or kill them related to how fast you get a medical care .
What are the causes for the heart attack?
A heart attack happens if the flow of oxygen-rich blood to a section of heart muscle suddenly becomes blocked. Most heart attacks occur as a result ofcoronary heart disease (CHD).CHD is a condition in which a waxy substance called plaque builds up inside of the coronary arteries. These arteries supply oxygen-rich blood to your heart. When plaque builds up in the arteries, the condition is called atherosclerosis. The buildup of plaque occurs over many years.Eventually, an area of plaque can rupture (break open) inside of an artery. This causes a blood clot to form on the plaque's surface. If the clot becomes large enough, it can mostly or completely block blood flow through a coronary artery.If the blockage isn't treated quickly, the portion of heart muscle fed by the artery begins to die. Healthy heart tissue is replaced with scar tissue. This heart damage may not be obvious, or it may cause severe or long-lasting problems.
Where does a heart attack occur in the heart?

What conditions are caused by blood clots?
A blood clot that blocks an artery to the brain can cause a stroke. If the clot blocks blood flow to the lungs pulmonary embolism can occur. A blood clot that blocks a coronary artery can cause a heart attack.
The blockage of which blood vessel causes a heart attack?
It is not really the blood vessel that starts a heart attack. Instead, it is the process of narrowing of the arteries that causes it. The heart has 3 main blood vessels that supply different parts of it. If any of these vessels get completely blocked by a blood clot or fat deposition, it could lead to a heart attack. Even if the branches of these vessels get blocked, it could lead to a heart attack.
What is a heart attck?
Most heart attacks occur as a result of coronary artery disease This disease is the buildup of plaque on the inner walls of the arteries leading to the heart. Eventually, a section of plaque can break open, causing a blood clot to form at the site. A heart attack occurs if the clot becomes large enough to cut off most or all of the blood flow through the artery.

Is having a heart at tact a permanent disability?
No. Most heart attacks occur as a result of coronary artery disease (CAD). CAD is the buildup over time of a material called plaque on the inner walls of the coronary arteries. Eventually, a section of plaque can break open, causing a blood clot to form at the site. A heart attack occurs if the clot becomes large enough to cut off most or all of the blood flow through the artery. The blocked blood flow prevents oxygen-rich blood from reaching the part of the heart muscle fed by the artery. The lack of oxygen damages the heart muscle. If the blockage isn't treated quickly, the damaged heart muscle begins to die.Heart attack also can occur due to problems with the very small, microscopic blood vessels of the heart. This condition is called microvascular disease. It's believed to be more common in women than in men.Another less common cause of heart attack is a severe spasm (tightening) of a coronary artery that cuts off blood flow through the artery. These spasms can occur in coronary arteries that don't have CAD. It's not always clear what causes a coronary artery spasm, but sometimes it can be related to:Taking certain drugs, such as cocaineEmotional stress or painExposure to extreme coldCigarette smoking
What are facts about heart attack?
1.5 million heart attacks occur in the United States each year. Women are more likely to die suddenly from a heart attack than men. Almost 50% of deaths from heart attack occur within one hour, outside a hospital.
What triggers a heart attack?
Atherosclerotic Plaque is an irregular accumulation of cholesterol and fat. When plaque is present in the coronary artery, a heart attack is likely to occur because of restricted blood flow.

Which is mainly affected during heart attack the organ that pumps blood the vessel that carries oxygenated blood the vessel that carries deoxygenated blood or where gas and nutrient exchange occur?
The most affected organ is the heart (organ) itself. The cause of a heart attack is when the arteries that feed the heart are blocked either by a clot or build-up of plaque. When the heart does not get enough blood, and therefore not enough oxygen, it sends out pain or distress signals- stabbing, crushing, or clenching chest pain, back pain, jaw or left arm pain, or pressure. The location of the pain is different for each individual and can vary depending on the location of the blocked artery. If the heart is deprived of enough oxygen for a long enough period of time, the heart muscle starts to die. Each cardiac artery feeds a certain area of the heart. So, depending on which artery is blocked, the heart attack can be more or less catastrophic depending on which area of the heart is damaged.
Is angina pectoris another name for heart attack?
No, it's another name for "chest pain". Chest pain is associated with having a heart-attack, but can also just occur by itself (without a heart-attack).
