Medically known as a myocardial infarction, a heart attack is when blood flow to a certain section of the heart is disrupted, or stops. This causes damage to the heart muscle. Heart attacks are usually caused by problems in the coronary arteries, which are the arteries that provide the heart with massive amounts of blood. Blood clots mostly cause spasms of the artery or blockages. When these pathways are clogged or narrow, it will make it more difficult for possible clots to pass through.
The most common symptoms of a heart attack are pressure, pain and a heaviness in the chest, arm or under the chest bone. Additionally, there can be a pain running around the throat and jaw and the back, sweating, and dizziness; weakness, irregular heartbeat and a feeling of heartburn can also be present. Although it must be stated that you can have a heart attack without any of the warning signs, this is called a silent myocardial infarction. A heart attack can last for up to 30 minutes and time is extremely important when experiencing or being with someone who is experiencing heart problems. In the U.S.A approximately 735,00 people a year have a heart attack.
