What Is a Heart Attack..?

When blood flow to a section of heart muscle becomes blocked, then a heart attack occurs. If the required blood isn’t restored quickly, the section of heart muscle becomes damaged because the lack of oxygen and it begins to die.
Today heart attack is a leading killer of both men and women in the United States and England. But fortunately, today we have excellent treatments for heart attack that can save lives and prevent disabilities. Treatment is most effective when is started within 1 hour of beginning of symptoms. If you feel a pain in the chest sometimes…? Then that small pain may lead to a large painful heart attack, if have, then you must contact your nearest heart specialist for further details.



More about...

Heart attacks occur most often as a result of a condition called coronary artery disease (CAD). In CAD, a fatty material called plaque (plak) builds up over many years on the inside walls of the coronary arteries (the arteries that supply blood and oxygen to your heart). Then, an area of plaque can rupture, causing a blood clot to form on the surface of the plaque. If the clot becomes large enough, it can mostly or completely block the flow of oxygen-rich blood to the part of the heart muscle fed by the artery.



Block in Artery

Figure ‘A’ is an overview of a heart and coronary artery showing damage (dead heart muscle) caused by a heart attack. Figure ‘B’ is a cross-section of the coronary artery with plaque buildup and a blood clot.


During a heart attack, if the blockage in the coronary artery isn’t treated quickly, the heart muscle will begin to die and be replaced by scar tissue. This heart damage may not be obvious, or it may cause severe or long-lasting symptoms and problems.
Problems linked to heart attack include heart failure and life-threatening arrhythmias (irregular heartbeats). Heart failure is a condition in which the heart can’t pump enough blood throughout the body. Ventricular fibrillation is a serious arrhythmia that can cause death if not treated quickly.


Common heart attack signs and symptoms

==> Chest discomfort or pain—uncomfortable pressure, squeezing, fullness, or pain in the center of the chest that can be mild or strong. This discomfort or pain lasts more than a few minutes or goes away and comes back.
==> Upper body gets discomforted in one or both arms, the back, neck, jaw, or stomach.
Shortness of breath may occur with or before chest discomfort.
==>Other signs include nausea (feeling sick to your stomach), vomiting, lightheadedness or fainting, or breaking out in a cold sweat.
Result
In every year more than 1.1 million people in USA becomes hear patient and almost half dies.
If we give help to those patients immediately, then many more people could recover from heart attacks. The people who dies because of heart attacks, about half of them die within an hour of the first symptoms and before they reach the hospital.
